For an enterprise vertical SaaS with annual contracts, I’d focus less on “affiliate software” in the consumer sense and more on whether the platform can handle contract-value-based commissions, recurring renewals, and one-time referral bonuses.

Strong candidates

Rewardful explicitly supports recurring or one-time commissions, percentage or fixed amounts, and tracks subscription changes such as upgrades, downgrades and cancellations. Rewardful Rewardful

FirstPromoter similarly calculates commissions from billing events and supports recurring commissions; its positioning is particularly SaaS-oriented. FirstPromoter

The important distinction for your use case

Suppose you have:

• $50,000 annual contract
• Partner refers the customer
• Partner gets 10% of first-year contract value = $5,000
• Then perhaps 5% of each renewal = $2,500/year
• Another partner type gets a $2,000 one-time referral fee
• Commission might be based on the actual contract/ARR rather than monthly Stripe payments

That last requirement is where I'd investigate PartnerStack or impact.com first rather than automatically choosing a lightweight SaaS affiliate tool. Current comparisons describe PartnerStack as oriented toward enterprise multi-type partner programs, whereas Rewardful/FirstPromoter are more straightforward SaaS affiliate systems. Affitor Documentation Affitor Documentation

One caveat: “recurring commission” does not necessarily mean “pay X% of the customer's annual contract on every renewal.” Some systems are fundamentally event/billing based. For enterprise SaaS, you should verify that the platform can ingest the contract value/ARR as the commission basis, particularly when contracts are negotiated offline and invoiced annually.

What I'd shortlist

• PartnerStack — investigate first if you're building a serious partner/channel program involving affiliates, consultants, agencies, referral partners, or resellers.
• impact.com — investigate if you want highly configurable enterprise partner management and potentially broader partner-network capabilities.
• FirstPromoter — attractive if the program is primarily referral/affiliate and your billing system is supported.
• Rewardful — very good if you're Stripe/Paddle-centric and the commission mechanics map cleanly to your billing events, but I'd validate the annual-contract/offline-deal workflow carefully.

If you tell me (1) your billing system (Stripe, Salesforce/CPQ, Chargebee, Zuora, invoices, etc.), (2) whether contracts are signed offline, and (3) the exact commission formula, I can narrow this to the 2–3 platforms that actually support that workflow rather than generic “SaaS affiliate” recommendations.

For enterprise vertical SaaS with annual contracts, I’d narrow the shortlist to FirstPromoter, Rewardful, and PartnerStack. The key distinction is whether you need simple affiliate tracking or a more enterprise-grade partner/commission system.

The important part for your model

Suppose you sell a $50,000/year contract and want:

• Referral partner A: 10% of first-year contract value = $5,000 one-time
• Strategic partner B: 10% of revenue every renewal = $5,000/year recurring
• Partner C: 5% for year 1, then 2.5% on renewals
• Commission calculated from the actual contract/charge rather than a fixed bounty.

FirstPromoter explicitly supports percentage/flat monetary commissions, one-time commissions, and recurring commissions that can run for the customer's lifetime, a defined period, or a fixed number of charges. FirstPromoter

PartnerStack is particularly interesting if the referral program is really becoming a B2B partner/channel program rather than a conventional affiliate program. It supports event-based triggers such as contract signing and recurring commissions tied to renewals and expansion. PartnerStack

Rewardful is attractive if your billing is primarily Stripe and you want a relatively simple implementation: its commission model supports recurring or one-time payments and percentage or fixed amounts. Rewardful

What I'd investigate first

For your particular setup, I'd test these three workflows before choosing:

1. $100k annual contract → 10% one-time referral fee
2. $100k annual contract → 10% recurring fee on each annual renewal
3. $100k contract → 10% year 1 + 5% years 2–3, with cancellation/refund/clawback handling.

If you expect enterprise contracts, sales-assisted attribution, CRM integration, multiple partner types, and potentially resellers, I'd look hardest at PartnerStack. If it's primarily an affiliate/referral program attached to your billing system, FirstPromoter is probably the more directly relevant product to evaluate. FirstPromoter PartnerStack

If you tell me your billing stack (Stripe/Chargebee/Salesforce/etc.), typical ACV, and whether the referral fee is paid on signed contract value or collected revenue, I can narrow this to 2–3 options and compare the exact commission mechanics.

1. $100k annual contract → 10% one-time referral fee
2. $100k annual contract → 10% recurring fee on each annual renewal
3. $100k contract → 10% year 1 + 5% years 2–3, with cancellation/refund/clawback handling.

If you expect enterprise contracts, sales-assisted attribution, CRM integration, multiple partner types, and potentially resellers, I'd look hardest at PartnerStack. If it's primarily an affiliate/referral program attached to your billing system, FirstPromoter is probably the more directly relevant product to evaluate.

For enterprise vertical SaaS with annual contracts, I’d focus less on “affiliate software” broadly and more on whether the platform can handle contract-value-based commissions, including a mix of:

• Recurring commissions — e.g. 10% of ARR for each renewal, perhaps for 12–24 months.
• One-off commissions — e.g. 5% of the initial ACV/contract value.
• Fixed or percentage commissions.
• Different rules by partner/affiliate.
• Ideally, billing/CRM events rather than just Stripe checkout, since enterprise deals often close through sales rather than self-serve checkout.

Shortlist

FirstPromoter is particularly interesting for your use case. Its commission engine supports recurring, time-limited, and one-time commissions, with either percentage or flat amounts. It can also adjust commissions when subscriptions are upgraded, downgraded, refunded, or cancelled. FirstPromoter FirstPromoter

firstpromoter.com

Rewardful explicitly supports both recurring and one-time commissions, including percentage or fixed amounts. It is heavily oriented around Stripe/Paddle, though, so I'd scrutinize it if your enterprise contracts aren't represented as Stripe subscriptions. Rewardful Rewardful

rewardful.com

PartnerStack is the one I'd investigate if you're building a genuine B2B partner/channel program rather than a conventional affiliate program. Its positioning is much closer to managing partners, referrals, resellers, and larger enterprise ecosystems. FirstPromoter Affitor

partnerstack.com

The important wrinkle for your model

Suppose your contract is:

$100,000 annual contract value

and you want:

Referral partner: 10% of first-year ACV = $10,000 one-time
OR 10% of every annual renewal for 3 years
OR 5% upfront + 5% on renewal

That's somewhat different from the typical SaaS affiliate model of “20% of every Stripe subscription payment.”

I'd therefore ask each vendor specifically:

1. Can I pass a $100k contract/ACV into the commission event via API?
2. Can I pay a percentage of that value rather than the actual invoice/payment?
3. Can I trigger a one-time commission at closed-won/contract signature?
4. Can I separately trigger recurring commissions on renewal?
5. Can the commission rules vary by partner?
6. Can I claw back/adjust commissions if the contract is cancelled or reduced?
7. Can attribution happen from CRM opportunity → customer, rather than requiring a tracked signup?

For an enterprise vertical SaaS, #1–#4 are the real differentiators. A tool can advertise “recurring commissions” but still be poorly suited to $50k–$500k sales-led contracts.

My initial shortlist would be FirstPromoter + PartnerStack, with Rewardful as a third option if you're heavily integrated with Stripe. FirstPromoter has unusually explicit support for both recurring and one-time monetary rewards, while PartnerStack is more aligned with a full B2B partner/channel motion. FirstPromoter Affitor

If you tell me your billing stack (Stripe/Chargebee/etc.), CRM (Salesforce/HubSpot), typical ACV, and exact commission formula, I can narrow this to 2–3 platforms and map out how each would implement your commission logic.

Yes. For a vertical SaaS selling enterprise annual contracts, I’d look beyond “affiliate software” and prioritize platforms that can handle B2B partner/referral economics—especially commissions based on contract value, one-time deal fees, and recurring/renewal payouts.

Best fits

1. PartnerStack — my first choice for your model

partnerstack.com

PartnerStack is particularly well suited if you're selling $10k–$100k+ annual contracts through consultants, industry partners, associations, agencies, or referral partners, rather than consumer-style affiliates.

It supports:

• One-time commissions
• Limited recurring commissions
• Unlimited recurring commissions
• Percentage-based commissions tied to transaction value
• Event-based triggers such as contract signing
• Recurring commissions on renewals and expansion
• Drip/installment commissions as revenue is realized
• Partner payouts beyond traditional affiliates, including referral, reseller and co-sell arrangements. PartnerStack PartnerStack Support PartnerStack

That last point is important for enterprise SaaS. You can model something like:

Partner refers $60k ACV customer → 10% referral fee = $6k
Renewal → 5% recurring commission
Expansion → commission on incremental contract value

rather than forcing your enterprise sales motion into an ecommerce affiliate model.

2. FirstPromoter — best if you want simpler SaaS affiliate mechanics

firstpromoter.com

FirstPromoter is surprisingly capable for this use case. It supports recurring, flat-fee, one-time and lifetime commissions, with commissions tied directly to billing events. It also supports annual/one-time charges and can calculate commissions based on the sale total and plan ID. FirstPromoter FirstPromoter FirstPromoter

It integrates natively with Stripe, Paddle, Chargebee, Recurly and Braintree, which makes it attractive if your contracts eventually flow through one of those billing systems. FirstPromoter

For example, you could have:

• New enterprise deal: 8% of first annual invoice
• Renewal: 3% of renewal invoice
• Expansion: 5% of incremental invoice
• Strategic referral: $2,500 flat bounty

That's much closer to what you're describing than a conventional affiliate program.

3. Rewardful — excellent if you're Stripe-centric

rewardful.com

Rewardful supports recurring or one-time commissions, percentage or fixed amounts, and calculates commissions from the amount actually paid on the invoice. It can also limit recurring commissions to a particular number of invoices. Rewardful Help Center Rewardful Help Center

So an annual-contract model can work nicely if the contract is represented as a Stripe invoice:

$40,000 annual invoice × 10% = $4,000 referral commission

And you could make it one-time, or have the commission repeat on subsequent invoices.

The caveat is that Rewardful is fundamentally optimized around Stripe/Paddle subscription billing, whereas PartnerStack is more naturally suited to a broader B2B partner ecosystem. Rewardful Help Center

4. Impact.com — worth considering for a sophisticated enterprise program

impact.com

I'd consider this if you expect the program to become a significant channel with multiple partner types, sophisticated attribution, contracts, approvals, and payout rules.

It's more of a partnership management platform than a lightweight affiliate tool, so I'd generally choose it when the complexity justifies the implementation.

What I'd choose

For a vertical SaaS with enterprise annual contracts, my shortlist would be:

1. PartnerStack — best overall if referrals/partners are a meaningful enterprise sales channel.
2. FirstPromoter — best simpler/leaner option if commissions can be derived from your billing system.
3. Rewardful — particularly attractive if you're already deeply integrated with Stripe.
4. Impact.com — best when you anticipate a sophisticated, multi-channel partner program.

The key distinction is contract-value-based commission vs. subscription-payment-based commission.

If your actual requirement is something like “pay 10% of ACV when the contract is signed, then 3% on each annual renewal, with different rates by partner tier and the ability to claw back if the customer churns”, I'd lean PartnerStack rather than a traditional affiliate tool. PartnerStack explicitly supports event-based and recurring commission structures, while FirstPromoter/Rewardful are stronger when the billing event itself is the source of truth. PartnerStack PartnerStack

If you tell me your typical ACV (e.g. $20k/$50k/$100k), CRM/billing stack (Salesforce/HubSpot/Stripe/etc.), and whether the referral fee is paid on booking or cash collection, I can narrow this to the 2–3 best platforms and show exactly how I'd structure the commission rules in each.

And you could make it one-time, or have the commission repeat on subsequent invoices.

The caveat is that Rewardful is fundamentally optimized around Stripe/Paddle subscription billing, whereas PartnerStack is more naturally suited to a broader B2B partner ecosystem. Rewardful Help Center

It's more of a partnership management platform than a lightweight affiliate tool, so I'd generally choose it when the complexity justifies the implementation.

What I'd choose

For an enterprise vertical SaaS with annual contracts, I’d focus less on traditional “affiliate software” and more on platforms that can handle contract-value-based commissions, recurring/renewal revenue, and one-time referral payouts.

Best fits

My top pick: PartnerStack

For your particular model, PartnerStack is probably the strongest fit.

It supports percentage- or flat-rate commissions, event-based triggers, recurring revenue share, deal registration, and more sophisticated commission structures. PartnerStack PartnerStack

Most importantly, it explicitly supports drip commissions for annual contracts. For example, PartnerStack gives the example of a $1,200 annual contract with a 20% commission ($240 total) that is paid as $20/month for 12 months. Partner Stack

That maps nicely to enterprise SaaS scenarios such as:

• 10% of first-year ACV, paid once after the customer pays.
• 10% of ACV, paid over 12 months.
• 5% of every renewal for as long as the account remains active.
• $2,000 fixed referral fee for contracts above a certain ACV.
• Different rates based on contract size or partner tier.
• Separate commissions for referrals, registered deals, renewals, and expansion.

PartnerStack also explicitly supports one-time, limited-recurring, and unlimited-recurring structures. Partner Stack PartnerStack

partnerstack.com

Rewardful is attractive if your billing is in Stripe

If your enterprise contracts are ultimately invoiced through Stripe, Rewardful is considerably simpler.

It supports both percentage and fixed commissions, and you can choose recurring commissions or cap the number of commissions—for example, paying only on the first invoice. Rewardful Help Center Rewardful Help Center

It calculates commissions against the actual amount paid on each Stripe invoice, including one-off invoices. Rewardful Help Center

So you could do something like:

Customer signs $50k annual contract → affiliate gets 10% of the $50k payment = $5k.

Or:

Customer pays $50k/year → affiliate gets 5% of every invoice for 3 years.

The caveat is that Rewardful is fundamentally Stripe/payment-centric, whereas PartnerStack is much better suited to an enterprise sales process where the referral may precede the eventual contract by months and you have deal registration, partner management, CRM events, etc. Rewardful Help Center

rewardful.com

The key distinction for your use case

I'd divide the decision this way:

If "affiliate" means someone sends traffic → prospect signs up → Stripe charges them:
→ Rewardful is probably the easiest.

If "affiliate" really means consultants, agencies, industry partners, associations, or referral partners who introduce enterprise accounts:
→ PartnerStack is much more appropriate.

That's because enterprise SaaS referrals often look like:

Partner referral → qualified opportunity → sales process → negotiated ACV → contract signed → invoice paid → renewal/expansion

rather than:

Affiliate click → checkout.

PartnerStack is explicitly built around B2B partners, deal registration, recurring revenue, and partner commissions, rather than just affiliate links. PartnerStack PartnerStack

What I'd choose

For a vertical SaaS selling $10k–$100k+ annual contracts, my shortlist would be:

1. PartnerStack — best overall for enterprise referral/partner economics.
2. impact.com — worth considering if you expect a sophisticated, multi-channel partnership ecosystem.
3. Rewardful — best if you want something much simpler and your billing flows through Stripe.
4. FirstPromoter / Tolt — worth evaluating if the program is relatively lightweight.

One particularly important requirement I'd validate in demos is whether the platform can calculate commission against contracted ACV rather than merely the amount of the initial transaction. For enterprise SaaS, that's often the difference between a genuinely useful partner system and a consumer-style affiliate tracker.

If you tell me your typical ACV (e.g. $20k, $50k, $100k), commission model (e.g. 10% first year + 5% renewals), and billing system (Stripe, Salesforce/Zuora, NetSuite, etc.), I can narrow this down to the 2–3 platforms that actually fit and show how I'd configure the commission rules.

It calculates commissions against the actual amount paid on each Stripe invoice, including one-off invoices. Rewardful Help Center

So you could do something like:

Customer signs $50k annual contract → affiliate gets 10% of the $50k payment = $5k.

Or:

Customer pays $50k/year → affiliate gets 5% of every invoice for 3 years.

rather than:

PartnerStack is explicitly built around B2B partners, deal registration, recurring revenue, and partner commissions, rather than just affiliate links.

What I'd choose

Yes. For an enterprise SaaS with annual contracts, I’d narrow the field to PartnerStack and Rewardful, with PartnerStack the stronger fit if your sales process is contract/deal-driven rather than self-serve.

1. PartnerStack — probably your best fit

partnerstack.com

PartnerStack explicitly supports percentage or flat commissions, one-time commissions, limited recurring commissions, and unlimited recurring revenue share. Its platform also supports event-based triggers such as contract signing, as well as recurring commissions on renewals and expansion revenue. PartnerStack Support PartnerStack PartnerStack

That maps nicely to something like:

• Referral closes $100k annual contract → 10% one-time commission = $10k
• Or: 5% of the initial contract + 3% on renewals
• Or: $5k for a qualified closed-won enterprise deal
• Different commission rules for different partner tiers/types

The particularly useful feature for your use case is that PartnerStack isn't limited to a Stripe-style "invoice happened → commission happened" model. It can operate around deals, milestones, customer events, renewals and expansion. PartnerStack PartnerStack

2. Rewardful — excellent if contracts ultimately flow through Stripe

rewardful.com

Rewardful supports recurring or one-time commissions, with either percentage or fixed amounts. It calculates commissions based on the amount actually paid on Stripe invoices, including one-off invoices. You can also limit commissions to the first invoice or a specified number of invoices. Rewardful Help Center Rewardful Help Center

So it's excellent for:

"Affiliate gets 10% of every invoice for 12 months"

or:

"Affiliate gets 10% of the first invoice only."

The caveat for an enterprise SaaS is important: if your $200k/year contract is signed in Salesforce and invoiced through a custom enterprise billing process, rather than being a straightforward Stripe transaction, PartnerStack is likely a better architectural fit.

What I'd choose for your specific model

If by "tied to contract value" you mean something like:

Partner refers an enterprise → sales closes a $250k annual contract → partner gets 10% of ACV, potentially with another commission on renewal

I'd choose PartnerStack.

If instead you mean:

Customer pays $250k through Stripe → automatically calculate 10% → continue paying 5% on subsequent invoices

I'd choose Rewardful.

The distinction is essentially deal/CRM-centric vs. billing-centric attribution.

One other consideration: enterprise contracts often have annual prepayment, negotiated discounts, expansions, renewals, cancellations and clawbacks. I'd make sure the vendor can calculate commissions from ACV/ARR or closed-won deal value, rather than merely from cash collected. PartnerStack's event-based and revenue-share model makes it considerably more suited to that kind of partner program. PartnerStack PartnerStack

If you tell me your exact commission rule (e.g. "10% of first-year ACV + 5% on renewals, paid after 90 days"), I can compare PartnerStack vs Rewardful vs FirstPromoter vs Tolt specifically against that workflow and identify which ones can implement it natively without custom development.

For a vertical SaaS selling enterprise annual contracts, you generally want a partner/affiliate platform that can handle high-ACV deals, not just ecommerce-style affiliate links. The key capabilities are:

• Commission calculated on contract value (ACV/ARR) rather than checkout amount
• Support for one-time referral fees (e.g., $2,000 per closed customer or 15% of first-year ACV)
• Support for recurring revenue share (e.g., 10% of ARR for 12 months, or lifetime)
• Manual deal registration / CRM attribution (because enterprise sales often close months after referral)
• Multi-touch attribution and partner tiers

Good fits:

Partnero Track360## My shortlist for enterprise vertical SaaS

1. PartnerStack — best overall for enterprise referrals

Use this if your motion looks like:

“A consulting firm refers a $100k/year customer, we pay them 15% of first-year ARR.”

Strengths:

• Partner portals
• Deal registration
• Referral workflows
• Partner tiers
• Recurring revenue commissions
• Works well for agencies, consultants, technology partners

Typical structures:

• 10–30% of first-year contract value
• Fixed bounty after closed-won
• Recurring percentage for renewals

2. Everflow — best for custom enterprise economics

Best if you need unusual rules:

Examples:

• Partner A gets $5,000 when a deal closes
• Partner B gets 15% of ACV
• Partner C gets 5% of ARR for 24 months
• Enterprise referrals require approval

Everflow is more of a configurable partner tracking engine than a simple affiliate tool.

3. Rewardful — best if billing is subscription-native

Good if:

• You use Stripe/Paddle
• Contracts are self-serve or lower ACV
• You want automated recurring commissions

Less ideal if:

• Deals are negotiated
• Sales cycles are 6–12 months
• Attribution happens through Salesforce opportunities

Rewardful-style tools are strongest when the customer journey is:
affiliate link → signup → subscription → recurring payout. Reddit

Commission models I would consider for enterprise vertical SaaS

Option A: Referral bounty

Best for consultants and industry experts.

Example:

• $3,000 when a referred company signs
• Paid after first invoice

Option B: First-year ACV percentage

Usually the cleanest enterprise model.

Example:

• 10% of first-year ACV
• $120k contract → $12k referral fee

Option C: Recurring revenue share

Best for strategic partners.

Example:

• 10% of ARR for 12 months
• $120k ARR → $12k total payout over the year

Option D: Hybrid

Often strongest for vertical SaaS.

Example:

• $2,000 qualified opportunity fee
• +10% of first-year ACV when closed
• +5% renewal share for 12 months

My recommendation by company stage

• <$5M ARR / building first partner channel: Everflow or Rewardful
• $5M–$50M ARR with consultants/agencies/resellers: PartnerStack
• Enterprise SaaS with Salesforce-driven deals: PartnerStack + CRM integration or Everflow
• Complex channel economics: Everflow

For a true enterprise vertical SaaS motion, I would usually avoid “affiliate software” and build a partner referral program around ACV attribution. The economics and workflows are closer to channel sales than creator affiliate marketing. Track360 scalepartner.pro

Yes. For an enterprise B2B SaaS with annual contracts, I’d narrow the field considerably. The key requirement is not just “recurring commissions”—you want commissions calculated from the actual contract value / billing events, plus the ability to make a one-time referral payment when appropriate.

Best fits

My recommendation: PartnerStack

For your specific model—enterprise SaaS + annual contracts + meaningful contract values—I'd put PartnerStack at the top of the shortlist.

It's designed more around B2B partner programs than consumer-style affiliate programs, and is particularly appropriate if your “affiliate” may actually be a consultant, agency, implementation partner, referral partner, or reseller. Current comparisons put PartnerStack in the enterprise category, alongside the more general-purpose impact.com. Affitor Documentation CompareSharp

The distinction matters because you might want rules such as:

• Partner introduces a $100k annual contract → 10% one-time referral fee
• Partner introduces a $100k customer → 5% of ARR for the first year
• Renewal → 2% recurring commission
• Expansion from $100k → $150k → commission on the incremental $50k
• Different commission rates for different partner tiers
• Fixed $5,000 referral bonus below a certain contract value
• Commission only after the customer actually pays

That's much closer to a B2B partner commission system than a traditional affiliate tracker.

Rewardful is interesting if you're Stripe-based

rewardful.com explicitly supports both recurring and one-time commissions, with either percentage or fixed amounts, and automatically handles subscription changes such as upgrades, downgrades, cancellations and refunds. Rewardful

So, for example, you could potentially structure:

$100k annual contract × 10% = $10k referral commission

and have that commission recur according to your campaign rules.

I'd favor Rewardful if your contracts ultimately flow through Stripe/Paddle and you don't need a sophisticated PRM/reseller ecosystem. Its current positioning is specifically around SaaS with Stripe/Paddle. Rewardful

FirstPromoter is the middle ground

firstpromoter.com is worth considering if you need broader billing integrations. It supports recurring commissions tied to billing activity, and current documentation/comparisons indicate support for Stripe, Paddle, Chargebee, Recurly and Braintree. Rewardful FirstPromoter

That makes it attractive if your enterprise billing isn't purely Stripe.

The important caveat: “contract value” vs. “subscription revenue”

This is the question I'd resolve before buying anything.

There's a meaningful difference between:

A. Billing-based commission

Customer pays $100k/year → platform sees $100k billing event → calculates 10% commission.

and:

B. Contract/ARR-based commission

Sales rep closes a $500k, 3-year contract → partner gets 5% of the $500k TCV, even though only $166k is invoiced this year.

The latter is much more of a partner/PRM + CRM integration use case. If your enterprise deals are negotiated in Salesforce/HubSpot and the commission needs to be based on ACV, ARR, TCV, bookings, or deal value rather than payment events, I'd lean strongly toward PartnerStack or impact.com, rather than a lightweight affiliate product.

What I'd shortlist

1. PartnerStack — best if this is really an enterprise referral/partner program, especially with Salesforce/CRM-driven deal registration and multiple partner types.
2. Rewardful — best if it's fundamentally a Stripe-based SaaS affiliate program and you want simple recurring + one-off commission rules.
3. FirstPromoter — strong middle ground, particularly with multiple billing providers.
4. impact.com — worth evaluating if you want a broader enterprise partner platform/marketplace rather than a SaaS-specific affiliate tool. Current pricing comparisons place its SaaS offering in the enterprise-oriented tier. Affitor Documentation

If you tell me your intended commission scheme (e.g. “10% of first-year ACV, paid once” vs. “5% every year the customer renews”), I can narrow this to the 2–3 platforms that actually support that exact calculation, including how they'd handle a $50k/$100k/$500k annual enterprise contract.

So, for example, you could potentially structure:

$100k annual contract × 10% = $10k referral commission

and have that commission recur according to your campaign rules.

I'd favor Rewardful if your contracts ultimately flow through Stripe/Paddle and you don't need a sophisticated PRM/reseller ecosystem. Its current positioning is specifically around SaaS with Stripe/Paddle. Rewardful

FirstPromoter is the middle ground

firstpromoter.com is worth considering if you need broader billing integrations. It supports recurring commissions tied to billing activity, and current documentation/comparisons indicate support for Stripe, Paddle, Chargebee, Recurly and Braintree. Rewardful FirstPromoter

Yes. For an enterprise B2B SaaS with annual contracts, I’d focus less on traditional “affiliate” tools and more on platforms that can handle contract/deal-based attribution + recurring revenue.

Best fits

*Primarily based on tracked billing/payment amounts rather than a sophisticated CRM-driven annual-contract workflow.

1. PartnerStack — probably your best match

PartnerStack explicitly supports one-time, limited-recurring, and unlimited-recurring commission structures. It also supports event-based commissions, including paying partners when contracts are signed, and connects to CRM/payment systems to track the resulting revenue. PartnerStack PartnerStack

That maps nicely to something like:

• Qualified opportunity: $250
• Closed-won: 10% of first-year contract value
• Renewal: 5% of renewal value
• Expansion: 5% of incremental contract value
• Or simply 20% of revenue for the first 12 months

PartnerStack specifically describes recurring revenue share covering subscriptions, renewals and expansion revenue. PartnerStack

For an enterprise SaaS where a referral may take months to go from lead → opportunity → signed annual contract, this is the one I'd investigate first.

2. impact.com — strongest if you need complex rules

impact.com is particularly interesting for your use case because its B2B SaaS documentation explicitly describes paying a percentage of annual contract value once the contract is signed, alongside separate payouts for earlier funnel events. It also supports continuous recurring payouts on subscriptions. Impact Help Impact Help

So you could potentially structure:

$500 for qualified opportunity → 10% of ACV at contract signature → 3% on subsequent recurring revenue

That's much closer to an enterprise referral/partner compensation system than a conventional ecommerce affiliate program.

3. FirstPromoter — good if your contracts ultimately flow through billing

FirstPromoter supports percentage or flat commissions, with commission duration configured as lifetime, a fixed number of months, or a fixed number of charges. It also supports different commission levels over time. FirstPromoter

For example:

10% of first invoice → 5% of invoices for the next 11 months

It's more attractive if your annual contracts are actually represented as invoices in Stripe/Chargebee/etc. than if your sales team is closing deals in Salesforce and the contract value exists primarily in CRM.

4. Rewardful — excellent technically, but probably not my first choice here

Rewardful supports both recurring and one-time commissions, including percentage or fixed amounts. It calculates commissions from the amount actually paid on Stripe invoices/charges. Rewardful Help Center Rewardful Help Center

So if your enterprise customer signs a $100k annual contract and that becomes a $100k Stripe invoice, Rewardful can be very straightforward.

But its own documentation positions it around Stripe/Paddle billing, and notes that it's not intended to be a full enterprise PRM with things like deal registration and complex reseller workflows. Rewardful

My recommendation

For your specific model, I'd shortlist:

1. PartnerStack — if referrals are a meaningful enterprise sales channel and you need CRM/deal/contract logic.

2. impact.com — if you need highly configurable payout rules and potentially multiple partner types/channels.

3. FirstPromoter — if the main requirement is straightforward recurring/one-time commission calculation against your billing system.

4. Rewardful — if you're primarily Stripe-based and want something considerably simpler.

The key question I'd use to choose between them is where the “contract value” lives. If it's in Salesforce/HubSpot before invoices exist, PartnerStack or impact.com is substantially more compelling. If it's simply the amount of a Stripe/Chargebee invoice, FirstPromoter or Rewardful may be much easier.

If you tell me your stack (e.g. Salesforce + Stripe, HubSpot + Chargebee, etc.) and the exact commission rule you want, I can narrow this to 1–2 options and explain how I'd implement it.

Yes. For enterprise vertical SaaS with annual contracts, I’d focus on platforms that can calculate commissions from the actual contract/invoice value, support both one-time referral fees and recurring revenue share, and ideally handle CRM/billing events rather than just ecommerce purchases.

Best fits

1. PartnerStack — strongest for enterprise SaaS

partnerstack.com

This is the one I'd investigate first for your model. PartnerStack is explicitly built around B2B/SaaS partnerships and supports percentage or flat commissions, one-time commissions, recurring commissions, renewals, expansion revenue, and event-based triggers. PartnerStack Support PartnerStack PartnerStack Support

For example, you could structure:

• 10% of first-year contract value when a referred enterprise customer closes.
• 5% of renewal revenue in years 2+.
• $2,500 one-time referral fee for contracts above $50k ACV.
• 2% expansion commission when the referred account expands.
• Different commission rules by partner tier or customer segment.

PartnerStack also specifically supports "drip" commissions, meaning commissions can be paid in installments as revenue is realized—useful if you don't want to pay a large referral commission before you've collected the customer's annual invoice. PartnerStack

It also has CRM-connected tracking and can track revenue through billing systems such as Stripe and Chargebee. PartnerStack

Caveat: PartnerStack is more of a full partner/PRM ecosystem than a lightweight affiliate tool, so it's likely overkill if you're only looking for referral tracking and payouts.

2. FirstPromoter — surprisingly good for this use case

firstpromoter.com

FirstPromoter supports percentage or flat-dollar commissions, and lets you choose whether they're one-time, recurring for a defined period, or lifetime. Its current billing integrations include Stripe, Paddle, Chargebee, Recurly and Braintree. FirstPromoter FirstPromoter

Importantly, it calculates commissions from the sale total, with support for annual/one-time billing and plan-level rules. FirstPromoter

So something like:

Partner refers $100,000 annual contract → 10% = $10,000 referral fee.

is conceptually a much better fit than software designed primarily around $50–$200/month consumer subscriptions.

You can also configure recurring commissions for a fixed number of months/charges—for example, 20% on the first 12 months rather than forever. FirstPromoter

I'd shortlist this if you want sophisticated commission logic without necessarily buying a full PRM.

3. Rewardful — good, but I'd rank it behind the first two

rewardful.com

Rewardful supports both recurring and one-time commissions, including percentage and fixed-amount commissions. You can make commissions apply indefinitely or cap them after a specified number of invoices/months. Rewardful Help Center Rewardful Help Center

It's particularly attractive if you're using Stripe heavily: Rewardful tracks Stripe invoices/charges and can follow the customer's billing activity. Rewardful Help Center

For example:

• $100k annual contract
• 10% commission
• Partner gets $10k on the first invoice
• Then 5% on subsequent renewals

is the kind of model it can accommodate.

The limitation is that Rewardful is fundamentally designed around subscription billing, whereas your sales motion sounds more like enterprise sales + partner/referral channel. For complex deal registration, sales pipeline, account expansion, partner tiers, etc., PartnerStack is more compelling.

My ranking for your specific model

If you're selling $20k–$500k+ annual enterprise contracts:

1. PartnerStack — best if partners are a meaningful GTM channel and you need deal registration, CRM integration, recurring/expansion commissions and sophisticated partner management.
2. FirstPromoter — best if you primarily need flexible commission calculation/tracking and want something simpler.
3. Rewardful — best if your infrastructure is heavily Stripe-based and the partner program is relatively straightforward.

One particularly important distinction: make sure "contract value" means what you think it means. Some platforms calculate a percentage of a billing event/invoice, while an enterprise referral program may need commission based on ACV/TCV at contract signature, potentially paid over time. PartnerStack's event/trigger and drip-commission capabilities make it particularly interesting for that distinction. PartnerStack PartnerStack Support

If you tell me your intended commission formula—for example “10% of first-year ACV + 2% on renewals” or “$5k one-time fee for deals >$50k ACV”—I can narrow this to the 2–3 platforms that can implement that exact logic, including whether you'd need an API/custom integration.

FirstPromoter supports percentage or flat-dollar commissions, and lets you choose whether they're one-time, recurring for a defined period, or lifetime. Its current billing integrations include Stripe, Paddle, Chargebee, Recurly and Braintree. help.firstpromoter.com firstpromoter.com

Importantly, it calculates commissions from the sale total, with support for annual/one-time billing and plan-level rules. help.firstpromoter.com

So something like:

Partner refers $100,000 annual contract → 10% = $10,000 referral fee.

is conceptually a much better fit than software designed primarily around $50–$200/month consumer subscriptions.

You can also configure recurring commissions for a fixed number of months/charges—for example, 20% on the first 12 months rather than forever. help.firstpromoter.com

I'd shortlist this if you want sophisticated commission logic without necessarily buying a full PRM.

3. Rewardful — good, but I'd rank it behind the first two

Yes. For enterprise vertical SaaS with annual contracts, I’d focus less on generic “affiliate” tools and more on whether the platform can handle contract-value-based commissions, one-time deal fees, and recurring renewal/expansion commissions.

Best fits

1. PartnerStack — probably your strongest option

For your model, PartnerStack is the one I'd investigate first.

It explicitly supports one-time, limited-recurring, and unlimited-recurring commission models, including percentage commissions tied to transaction value. PartnerStack Support

More importantly for enterprise SaaS, it supports event-based commissions and can trigger rewards around things such as demo completion, contract signing, renewals, expansion revenue, and other milestones. PartnerStack PartnerStack

That makes it much more suitable for something like:

Partner introduces Enterprise A → $120k annual contract → partner gets 10% of first-year ACV ($12k) → 3% on renewal → 3% on expansion.

Or:

Partner-sourced deal → $100k+ contract → $10k one-time referral fee, regardless of when/how the customer pays.

PartnerStack also specifically supports recurring subscription payments, renewals and upsells. PartnerStack

The tradeoff is that it's much more of a B2B partner-management platform than a lightweight affiliate tool, and it's priced accordingly.

2. Rewardful — excellent if the contract eventually runs through Stripe

Rewardful is particularly interesting if your enterprise contracts are ultimately invoiced through Stripe.

It supports both recurring and one-time commissions, percentage or fixed amounts, and can limit commissions to a particular number of invoices. Rewardful Help Center Rewardful

It calculates commissions based on the amount actually paid on an invoice, and supports both recurring subscription invoices and one-off invoices. Rewardful Help Center

So you could do:

• 10% of every invoice indefinitely
• 10% of first invoice only
• 10% of first 12 invoices
• fixed $5,000 referral fee on the first invoice

That's quite attractive if your "annual contract" is represented as a $100k Stripe invoice.

The limitation is that enterprise sales often have a sales-qualified lead → opportunity → negotiated contract → invoice workflow, rather than a clean online checkout. Rewardful is much more naturally suited to the latter.

3. FirstPromoter / Tolt

I'd consider these if you want something lighter than PartnerStack.

They are capable SaaS affiliate platforms with recurring commissions, but for a high-ACV enterprise referral program, I'd want to verify the exact workflow for:

• commission based on ACV/TCV rather than payment amount
• manually approved enterprise deals
• commission triggered by contract signature
• different commission rates by partner tier
• renewals and expansions
• clawbacks
• deal registration
• Salesforce/CRM integration

Those details matter considerably more for your use case than whether the product simply says "recurring commissions."

The key distinction for your business

I'd separate your desired commission model into these two cases:

A. Revenue-based

$100k annual contract → partner receives 10% of revenue actually collected.

Rewardful can be a very good fit here, particularly with Stripe. Rewardful Help Center

B. Contract-value-based

$100k ACV contract signed → partner receives $10k, even if payment is quarterly/monthly.

For this, PartnerStack is substantially more interesting, because its event-based and deal-oriented commission machinery is designed for B2B partner programs. PartnerStack PartnerStack

My shortlist

For an enterprise vertical SaaS, I'd rank them:

1. PartnerStack — best overall for enterprise/channel/referral partners.
2. Rewardful — best if your billing is Stripe-centric and you want simple implementation.
3. FirstPromoter — worth evaluating for a lighter-weight SaaS program.
4. Tolt — worth evaluating if simplicity/cost is more important than sophisticated enterprise deal workflows.

One important caveat: if by "tied to contract value" you mean “the affiliate should receive X% of ACV at the moment the contract is signed, before the customer pays”, rather than “X% of invoices collected,” that changes my recommendation quite a bit. PartnerStack is the first one I'd test for that workflow.

If you tell me your desired commission rule (e.g. “10% of first-year ACV + 2% on renewals”), I can also map out exactly how I'd implement it in PartnerStack vs. Rewardful and identify which one handles it natively versus requiring CRM/API work. PartnerStack Support Rewardful Help Center

Rewardful can be a very good fit here, particularly with Stripe. Rewardful Help Center

B. Contract-value-based

$100k ACV contract signed → partner receives $10k, even if payment is quarterly/monthly.

For this, PartnerStack is substantially more interesting, because its event-based and deal-oriented commission machinery is designed for B2B partner programs.

My shortlist

For an enterprise vertical SaaS, I'd rank them:

Rewardful can be a very good fit here, particularly with Stripe.

B. Contract-value-based

It supports both recurring and one-time commissions, percentage or fixed amounts, and can limit commissions to a particular number of invoices.

It calculates commissions based on the amount actually paid on an invoice, and supports both recurring subscription invoices and one-off invoices.

So you could do:

Yes. For a vertical SaaS selling annual enterprise contracts, I’d narrow the field considerably. The key distinction is whether you need subscription billing commissions or deal/contract-based commissions.

Best fits

PartnerStack is particularly interesting for your model because it explicitly supports recurring commissions, one-time actions, event-based triggers such as contract signing, and deal registration. Its documentation also supports one-time, limited-recurring, and unlimited-recurring commission structures. PartnerStack PartnerStack PartnerStack

The model I'd use for your business

Suppose you sell a $100k/year contract through a referral partner.

You might want:

• $5,000 one-time commission when the contract closes, or 5% of first-year ACV
• 2% recurring commission on renewals
• 2% on expansion/upsell revenue
• Commission only after cash is collected
• Clawback if the customer cancels/refunds
• Different rates by partner tier

That's much closer to a B2B partner/deal-registration program than a traditional consumer affiliate program.

PartnerStack is the first platform I'd evaluate. It is purpose-built around B2B SaaS, and its current offering specifically describes commissions tied to subscriptions, renewals, expansion revenue and contract-signing milestones. PartnerStack

Where FirstPromoter and Rewardful fit

FirstPromoter is surprisingly flexible. It supports percentage, flat-fee, one-time, lifetime-recurring and tiered commissions, with commission logic tied to billing events. FirstPromoter

So if your $100k enterprise contract actually flows through a supported billing system and you want something like 5% first payment + 2% subsequent payments, it's worth looking at.

Rewardful similarly supports recurring or one-time commissions and either percentage or fixed amounts, and automatically handles billing changes such as upgrades, downgrades and cancellations. Rewardful Rewardful

The catch is that Rewardful is fundamentally a Stripe/Paddle-centric SaaS affiliate tool, whereas you're describing an enterprise sales motion. Rewardful itself says a full enterprise PRM with things like reseller management and deal registration is outside its sweet spot. Rewardful

My shortlist

I'd evaluate them in this order:

1. PartnerStack — if partners influence enterprise deals and you need deal registration, CRM integration, recurring revenue share, and partner management.
2. impact.com — if you want a broader enterprise partnership platform and sophisticated tracking.
3. FirstPromoter — if the primary requirement is highly configurable commission calculation and your billing stack fits.
4. Rewardful — if you're relatively simple and Stripe/Paddle is the source of truth.

One important question: if by "tied to contract value" you mean “pay the affiliate X% of the $100k annual contract even though the actual Stripe invoice/payment happens later”, that changes my recommendation substantially. In that case I'd favor PartnerStack/impact.com over Rewardful/FirstPromoter, because you need CRM/deal-level attribution rather than merely payment-level attribution. PartnerStack

If you tell me your CRM (Salesforce/HubSpot), billing system, typical ACV, and desired commission formula, I can narrow this to the 2–3 platforms that actually fit and compare their pricing.

Rewardful similarly supports recurring or one-time commissions and either percentage or fixed amounts, and automatically handles billing changes such as upgrades, downgrades and cancellations.

Yes. For enterprise vertical SaaS with annual contracts, the key distinction is whether you need commissions calculated from the actual contract/ARR value rather than a simple Stripe subscription payment.

Best fits

PartnerStack is the one I'd investigate first for your use case. It explicitly supports B2B SaaS, recurring revenue share, renewals/expansion, deal registration, and one-time actions. Its commission system is event-based rather than being limited to ecommerce-style purchases. PartnerStack PartnerStack

That matters if your economics look like:

• $50k annual contract → partner gets 10% of contract value = $5k
• Renewal → partner gets 5% recurring
• Expansion → partner gets 5% of incremental ARR
• Strategic referral → perhaps $2,500 one-time bounty
• Different partner tiers → different percentages

FirstPromoter is particularly interesting

firstpromoter.com supports percentage or flat commissions, one-time commissions, recurring/lifetime commissions, and commissions based on billing events. It can also distinguish monthly, annual, and one-time charges and calculate commissions from the sale total/plan ID. FirstPromoter FirstPromoter FirstPromoter

So if your annual contracts are actually invoiced through Stripe, Chargebee, Paddle, Recurly, or Braintree, FirstPromoter could work very well. FirstPromoter

The caveat is important: enterprise SaaS often closes contracts in a CRM before payment occurs. If you need "pay 10% of booked ACV when Salesforce marks the opportunity Closed Won," rather than "pay 10% of the invoice when it's paid," I'd favor PartnerStack.

Rewardful

rewardful.com is very good technically for recurring + one-time commissions. It supports percentage or fixed commissions and can limit recurring payments to one invoice, several invoices, or an arbitrary period. It calculates the commission from the amount actually paid. Rewardful Help Center Rewardful Help Center

But Rewardful itself says it's designed around Stripe/Paddle and isn't intended to be a full enterprise PRM. Rewardful

So I'd choose it if your motion is essentially:

affiliate → customer → Stripe/annual invoice → automatic commission

rather than:

partner → lead → Salesforce opportunity → negotiated enterprise contract → ARR/ACV commission → renewal/expansion.

My shortlist for your specific model

I'd rank them:

1. PartnerStack — best if these are true enterprise partners/referral partners and you need CRM/deal/contract economics.
2. FirstPromoter — best value if commission can be anchored to billing events and you want flexible recurring/one-time rules.
3. Rewardful — excellent if you're Stripe/Paddle-centric and don't need a sophisticated B2B partner-management layer.

One thing I'd specifically verify in demos is whether "contract value" can be the commission base before the first invoice is paid, and whether the platform can handle ACV/TCV, renewals, expansions, cancellations/clawbacks, and multi-year contracts. That's the part that separates a genuinely good enterprise SaaS partner platform from a generic affiliate tracker.

If you tell me your desired commission structure (e.g. 10% of first-year ACV + 5% on renewals), I can narrow this down to the 2–3 platforms that can implement it natively without custom development.

But Rewardful itself says it's designed around Stripe/Paddle and isn't intended to be a full enterprise PRM.

So I'd choose it if your motion is essentially:

affiliate → customer → Stripe/annual invoice → automatic commission

rather than:

Yes. For enterprise vertical SaaS with annual contracts, I’d focus less on generic “affiliate software” and more on whether the platform can handle deal-level attribution + contract-value-based commissions + recurring renewals.

Best fits

1. PartnerStack — probably the closest match

For your model, PartnerStack is the one I'd investigate first.

It explicitly supports recurring revenue share, including renewals and upsells, while also supporting deal registration and one-time actions. PartnerStack PartnerStack

That matters because an enterprise referral might look like:

Partner introduces Account A → $120k annual contract → partner gets 10% of first-year ACV → $12k commission.

Then you could have a different rule for subsequent years:

Year 2 renewal → 5% recurring commission → $6k.

And potentially:

Expansion from $120k → $180k → commission on the $60k expansion.

That's much closer to a channel/partner program than a conventional affiliate program.

PartnerStack is also positioned specifically for larger B2B SaaS programs, although it is substantially more expensive than lightweight affiliate tools. Current third-party comparisons put entry pricing around $1,000/month, with enterprise pricing negotiated. Affitor Documentation

2. Rewardful — surprisingly capable if you're Stripe-based

Rewardful is worth considering if your contracts ultimately run through Stripe/Paddle.

It supports:

• recurring or one-time commissions
• percentage or fixed commissions
• recurring payments
• upgrades/downgrades
• refunds/cancellations

Rewardful RewardfulSo a simple model such as “10% of every referred invoice” is a natural fit.

The caveat is the enterprise sales process. Rewardful itself says it's not intended to be a full enterprise PRM for things like reseller management and deal registration. Rewardful

So I'd choose it if your workflow is:

referral → customer signs → Stripe invoice → commission

rather than:

partner registers opportunity → sales team accepts opportunity → contract negotiated → partner gets ACV commission → renewal/expansion management.

3. FirstPromoter

FirstPromoter is another good middle ground. It supports SaaS-oriented recurring commissions and MRR-based commission logic, and has broader billing-provider support than Rewardful. Affitor Documentation

I'd put it ahead of Rewardful if your billing isn't purely Stripe/Paddle.

4. impact.com

impact.com becomes interesting if you're building a more sophisticated partner ecosystem rather than simply an affiliate program.

It's much more enterprise-oriented and can handle multiple partner models and commission structures. The tradeoff is complexity and cost; current SaaS pricing comparisons put its SaaS-capable plans considerably above the lightweight affiliate products. Affitor Documentation

The key question for your use case

I'd distinguish between these two commission models:

A. Revenue-event based

Customer pays $100k → software records $100k transaction → affiliate gets 10%.

Rewardful/FirstPromoter can be very good here.

B. Contract/deal based

Partner registers opportunity → $250k ACV contract is signed → pay partner 8% of ACV ($20k) → pay 3% on years 2–3 → pay commission on expansion.

For this, PartnerStack or impact.com are much more appropriate.

If your vertical SaaS has $20k–$500k+ ACVs, sales-assisted deals, annual contracts, and partners such as consultants, agencies, associations, or industry vendors, I'd strongly favor PartnerStack over a traditional affiliate platform.

My shortlist would therefore be:

1. PartnerStack — best for a true enterprise partner/referral program.
2. impact.com — best if you need a broad, sophisticated partner ecosystem.
3. Rewardful — best value if the mechanics are primarily Stripe-based referral commissions.
4. FirstPromoter — good middle ground, especially with multiple billing systems.

One thing I'd verify in demos is whether “% of contract value” can be calculated from the signed ACV/deal amount rather than merely from the first invoice/payment. That's the distinction that can make or break an enterprise SaaS referral setup.

referral → customer signs → Stripe invoice → commission

rather than:

partner registers opportunity → sales team accepts opportunity → contract negotiated → partner gets ACV commission → renewal/expansion management.

3. FirstPromoter

FirstPromoter is another good middle ground. It supports SaaS-oriented recurring commissions and MRR-based commission logic, and has broader billing-provider support than Rewardful. Affitor Documentation

I'd put it ahead of Rewardful if your billing isn't purely Stripe/Paddle.

4. impact.com

impact.com becomes interesting if you're building a more sophisticated partner ecosystem rather than simply an affiliate program.

It's much more enterprise-oriented and can handle multiple partner models and commission structures. The tradeoff is complexity and cost; current SaaS pricing comparisons put its SaaS-capable plans considerably above the lightweight affiliate products. Affitor Documentation

The key question for your use case

I'd distinguish between these two commission models:

A. Revenue-event based

Customer pays $100k → software records $100k transaction → affiliate gets 10%.

Rewardful/FirstPromoter can be very good here.

B. Contract/deal based

Partner registers opportunity → $250k ACV contract is signed → pay partner 8% of ACV ($20k) → pay 3% on years 2–3 → pay commission on expansion.

4. FirstPromoter — good middle ground, especially with multiple billing systems.

One thing I'd verify in demos is whether “% of contract value” can be calculated from the signed ACV/deal amount rather than merely from the first invoice/payment. That's the distinction that can make or break an enterprise SaaS referral setup.

Yes. For enterprise SaaS with annual contracts, I’d narrow the field to PartnerStack and FirstPromoter, with Rewardful as a simpler option if your billing is Stripe-centric.

My recommendation: PartnerStack

partnerstack.com is probably the best fit if you're selling $10k–$100k+ annual contracts through agencies, consultants, technology partners, affiliates, or referral partners.

It supports:

• One-time commissions — e.g. 10% of the first contract.
• Limited recurring commissions — e.g. 10% of revenue for the first 12 months.
• Unlimited recurring commissions — e.g. 10% on renewals.
• Event-based commissions, including contract-signing milestones.
• Tracking recurring revenue, renewals and expansion/upsell revenue. PartnerStack Support PartnerStack PartnerStack

So you could construct something like:

Referral partner: 10% of first-year ACV when the contract closes
Renewal: 5% of renewal ACV
Expansion: 5% of incremental contract value

That's much closer to an enterprise channel/referral program than a traditional consumer affiliate program.

FirstPromoter is particularly interesting

firstpromoter.com is worth a serious look if you want something lighter-weight.

It explicitly supports percentage or flat commissions, one-time commissions, lifetime recurring commissions, and commissions tied to billing events. Its current documentation also says it supports annual charges and automatically calculates commissions from the sale total and plan ID. FirstPromoter FirstPromoter

For example, you could potentially configure:

• $50k annual contract → 10% referral = $5,000 one-time
• Or 10% on each annual renewal
• Or a combination where the first contract gets one rate and renewals another.

It also integrates natively with Stripe, Paddle, Chargebee, Recurly and Braintree. FirstPromoter FirstPromoter

Rewardful

rewardful.com can do both recurring and one-time commissions and calculates the commission from the amount actually paid on the invoice. Rewardful Help Center Rewardful Help Center

I'd choose it primarily if you're Stripe-based and want simplicity. For a complex enterprise referral/channel program, PartnerStack is more compelling.

The important distinction for your use case

If by "tied to contract value" you mean:

"Partner refers an enterprise customer, the customer signs a $75,000/year contract, and we owe the partner 10% of that $75k."

then PartnerStack is the first platform I'd evaluate.

If instead you mean:

"We want a lightweight affiliate system that takes the actual Stripe/Chargebee invoice amount and calculates 10% automatically."

then FirstPromoter is arguably the more straightforward choice.

If you tell me your typical ACV (e.g. $20k, $50k, $100k+), billing system (Stripe/Chargebee/etc.), and whether referrals are self-serve affiliates vs. sales partners, I can narrow this to the best 2–3 and compare pricing + commission mechanics + CRM integration + payout workflow.

Yes. For enterprise vertical SaaS with annual contracts, I’d prioritize platforms that can calculate commissions from the actual contract/invoice value, rather than tools designed mainly around ecommerce transactions.

Best fits

1. PartnerStack — probably the strongest match

PartnerStack is particularly well suited if your "affiliate" program is really a referral/partner channel.

It supports:

• One-time commissions on the first transaction.
• Limited recurring commissions, e.g. 20% of revenue for 12 months.
• Unlimited recurring commissions, e.g. 20% of revenue indefinitely.
• Recurring revenue, renewals, and upsells can be tracked.
• Deal registration, which is especially relevant when an enterprise referral turns into a sales-led contract. PartnerStack Support PartnerStack

For example, you could structure:

Partner introduces $100k annual contract → 10% referral fee = $10k
Renewal → 5% recurring commission = $5k/year
Expansion → 5% on incremental ARR

That's much closer to how enterprise SaaS partner economics actually work than a conventional consumer affiliate program.

The downside is cost/complexity: PartnerStack is an enterprise-oriented platform, and its pricing includes an annual subscription plus fees tied to partner commissions. PartnerStack

2. FirstPromoter — strongest if you want flexible commission logic

FirstPromoter is interesting for your specific requirement because it explicitly supports percentage or flat commissions, with one-time, time-limited, and lifetime recurring structures. It can calculate commissions based on the billing event and plan. FirstPromoter FirstPromoter

It also supports Stripe, Chargebee, Paddle, Recurly, and Braintree, and its current product supports commission logic around renewals, upgrades, downgrades, cancellations, etc. FirstPromoter

I'd look closely at this one if your requirement is something like:

• $X fixed fee for a qualified enterprise referral
• OR 10% of first-year contract value
• OR 5% recurring commission on renewals
• Different commission rates by plan/product
• Occasional manually assigned bonuses

It's more flexible than the typical lightweight affiliate tool.

3. Rewardful — excellent if you're Stripe-centric

Rewardful supports both recurring and one-time commissions, including percentage and fixed-amount commissions. It calculates the commission against the actual amount paid on the invoice. Rewardful Help Center Rewardful Help Center

So if your $100k annual enterprise contract generates a $100k Stripe invoice, you can theoretically make the referral commission a percentage of that invoice.

However, there's an important distinction: Rewardful is primarily a billing/affiliate attribution system, not a full enterprise partner-management system. Its own documentation positions it as a SaaS/Stripe-focused solution rather than a full PRM. Rewardful

I'd choose it when your model is relatively simple and you're already on Stripe.

The key question for your use case

There's a potentially important wrinkle: "contract value" isn't necessarily the same as "invoice value."

For enterprise SaaS, you may want:

Referral fee = 8% × first-year ACV

rather than:

Referral fee = 8% × whatever Stripe happens to charge.

If you have $250k+ annual contracts, multi-year agreements, negotiated pricing, annual invoicing, sales-assisted attribution, deal registration, and commissions on expansions/renewals, I'd lean PartnerStack.

If it's more like $10k–$100k contracts with a straightforward billing integration, I'd investigate FirstPromoter first, then Rewardful if you're on Stripe.

My shortlist for your exact scenario:

1. PartnerStack — best overall for enterprise SaaS referral/partner economics.
2. FirstPromoter — best for flexible commission rules without going all the way into a heavyweight PRM.
3. Rewardful — best simple option if you're Stripe/Paddle-based.
4. impact.com — worth considering if you're building a large, sophisticated partner ecosystem.

If you tell me your typical ACV (e.g. $25k/$100k/$500k), billing system (Stripe/NetSuite/etc.), and the exact commission rule you want (e.g. “10% of first-year ACV + 5% on renewals”), I can narrow this to the 2–3 platforms that actually support that workflow rather than just generic “recurring commissions.”

So if your $100k annual enterprise contract generates a $100k Stripe invoice, you can theoretically make the referral commission a percentage of that invoice.

However, there's an important distinction: Rewardful is primarily a billing/affiliate attribution system, not a full enterprise partner-management system. Its own documentation positions it as a SaaS/Stripe-focused solution rather than a full PRM. Rewardful

Yes. For enterprise SaaS with annual contracts, I’d narrow the field to FirstPromoter, PartnerStack, and Rewardful, with an important distinction around how you want the commission calculated.

My picks

1. FirstPromoter — probably the best fit if you want flexible commission rules

FirstPromoter explicitly supports one-time, recurring, multi-tier and custom rewards per plan/product, and ties commissions to billing events. It integrates with Stripe, Paddle, Chargebee, Recurly and others. FirstPromoter FirstPromoter

That makes it attractive for something like:

• $100k annual contract → partner gets 10% of first-year contract value
• Renewal → 5% recurring commission
• Expansion → 5% of incremental contract value
• Certain partners → flat $5k referral fee
• Different plans → different commission rules

2. PartnerStack — best if "affiliate" is really becoming an enterprise partner/channel program

PartnerStack explicitly supports recurring revenue share on subscriptions, renewals and upsells, as well as deal registration and one-time CPL/CPC/CPA-style commissions. PartnerStack

I'd choose this if you're selling through consultants, agencies, technology partners, resellers, etc., rather than just content affiliates. It's considerably more of a B2B partner-management platform than a lightweight affiliate tracker.

3. Rewardful — excellent if your billing is Stripe and you want simplicity

Rewardful supports recurring or one-time commissions, percentage or fixed amounts, and calculates commissions against the amount actually paid on Stripe invoices—including one-off invoices. Rewardful Rewardful Help Center

The catch is that it's fundamentally optimized around Stripe/Paddle-style billing, so I'd be less inclined to use it if your enterprise contracts involve a lot of manual invoicing, negotiated order forms, annual renewals, Salesforce opportunities, etc.

The key question for your use case

If by "tied to contract value" you mean:

"A partner refers an enterprise deal worth $250k ARR, and I want the software to automatically calculate a $25k referral fee from the contract/transaction value."

Then PartnerStack or FirstPromoter are the ones I'd investigate first.

If you mean:

"I want $10k paid when the deal closes, then 5% of each annual renewal and 5% of expansion revenue."

I'd lean PartnerStack, because deal registration + recurring revenue share + upsells is much closer to a traditional enterprise channel program. PartnerStack

If you tell me your CRM/billing stack (e.g. Salesforce + Stripe/NetSuite/Zuora) and the exact commission formula you have in mind, I can narrow this to 2–3 platforms and map out whether each can actually automate it.

For an enterprise vertical SaaS with annual contracts, I’d narrow the field to PartnerStack, impact.com, FirstPromoter, and Rewardful—but they fit your use case quite differently.

My shortlist

1. PartnerStack — probably your best fit

partnerstack.com is purpose-built around B2B SaaS and supports one-time, limited-recurring, and unlimited-recurring commission structures. It can pay based on transaction/revenue events, including subscriptions, renewals and expansion. PartnerStack PartnerStack Support

For example, you could structure:

• New enterprise referral: 10% of first-year contract value
• Renewal: 5% of renewal value
• Expansion: 5% of incremental ARR
• Or $5,000 one-time bounty when an enterprise deal closes
• Or 10% of every annual invoice for the first 12 months

That's much closer to an enterprise partner/referral program than a conventional consumer affiliate program.

2. impact.com — strongest for sophisticated deal economics

impact.com is particularly interesting if the referral process goes through your sales team rather than straight through checkout.

Its SaaS offering explicitly supports triggering payouts at stages such as subscription, upgrade, renewal, and integrating with Salesforce/HubSpot so commissions can be tied to pipeline progression. Impact

Its commissioning system also supports dynamic payouts based on variables and recurring commissions. Impact Help Center

I'd favor this if you need rules like:

Partner gets 8% of first-year ACV if the opportunity closes, plus 3% on expansion revenue, but only if the partner sourced the opportunity.

3. FirstPromoter — surprisingly capable

firstpromoter.com now supports recurring, time-limited, and one-time commissions, with either percentage or flat-dollar rewards. FirstPromoter

It can also calculate commissions from the actual sale amount and plan ID, which is useful if different enterprise packages have different referral economics. FirstPromoter

It supports Stripe, Paddle, Chargebee, Recurly and Braintree natively. FirstPromoter

The important distinction: if your enterprise deals are sales-led and the contract is negotiated in Salesforce before an annual invoice is generated, I'd put PartnerStack/impact.com ahead of it.

4. Rewardful — good, but more billing-centric

rewardful.com supports both recurring and one-time commissions, percentage or fixed amounts. Rewardful

It calculates commissions against invoices/charges, including one-off invoices, and can limit recurring commissions to a particular number of payments. Rewardful Help Center Rewardful Help Center

So it's excellent for something like:

10% of every annual invoice generated by a referred customer.

But I'd be more cautious if your definition of "contract value" is ACV/TCV in a CRM, rather than the amount actually invoiced through Stripe.

What I'd choose for your model

If you're selling $20k–$500k+ annual contracts through an enterprise sales process, my ranking would be:

1. PartnerStack — best balance of SaaS-native recurring economics + partner management.

2. impact.com — best if you need highly customized commission logic tied to CRM/deal stages.

3. FirstPromoter — best if you want something substantially simpler/cheaper and your billing system is supported.

4. Rewardful — excellent for Stripe-driven SaaS, but less compelling for complex enterprise referral contracts.

One important thing to clarify before choosing: "tied to contract value" can mean two very different implementations—commission calculated from the signed ACV/TCV in Salesforce, or commission calculated from the actual invoices/payments. For enterprise SaaS, that distinction is huge.

If you tell me your typical ACV (e.g. $25k/$50k/$100k+), CRM (Salesforce/HubSpot), billing system, and desired referral structure, I can narrow this to the best 2–3 and show exactly how I'd configure the commission rules.

For an enterprise SaaS with annual contracts, I’d narrow the field considerably. The key distinction is whether you mean:

1. Commission on actual contract value — e.g. 10% of a $100K ACV deal.
2. Recurring commission — e.g. 10% of each renewal/payment.
3. Different payout types in the same program — e.g. $500 for a qualified referral + 10% of ACV when it closes.

Best fits

1. PartnerStack — probably your strongest choice

PartnerStack is explicitly built around B2B SaaS and supports one-time, limited-recurring, and unlimited-recurring commissions. Its commission engine can also trigger payouts on events such as contract signing, and it supports recurring revenue, renewals and expansion. PartnerStack PartnerStack PartnerStack

Importantly for enterprise contracts, PartnerStack supports drip/installment commissions, so you can structure something like:

$1,000 when the deal closes + 10% of recognized subscription revenue over the contract term.

That is much closer to an enterprise referral/channel model than a traditional consumer affiliate system. PartnerStack

I'd pick this if: you're selling $25K–$500K+ ACV contracts and expect partners to include consultants, agencies, technology partners, or strategic referrers—not just content affiliates.

2. impact.com — strongest for highly customized contract-value logic

impact.com is particularly interesting if your commission needs are more bespoke.

Their B2B SaaS documentation specifically describes the pattern you're asking about: paying a smaller flat fee for a qualified lead and then paying a percentage of annual contract value once the contract is signed. Impact Help

It also supports recurring commissions and dynamic commissioning based on different variables. Impact Help Impact Help

So you could potentially model:

• $250 → qualified opportunity
• $2,500 → closed-won
• 8% → first-year contract value
• 3% → renewal revenue
• bonus → contracts above $100K ACV

I'd pick this if: your sales/partner compensation model is complicated and you want a fairly powerful enterprise-grade rules engine.

3. Rewardful — excellent technically, but I'd be cautious for enterprise ACV

Rewardful supports both recurring and one-time commissions, including percentage or fixed amounts. It calculates commissions against invoices actually paid, including one-off invoices. Rewardful Help Center Rewardful Help Center

That's excellent if your enterprise customers actually pay through Stripe and your "contract value" corresponds reasonably closely to Stripe billing.

But there's an important difference:

$100K annual Stripe invoice → 10% commission = easy.

$100K signed contract → $10K commission, with payment potentially occurring through procurement/ACH/manual invoicing and with special rules around bookings, renewals, expansions, clawbacks, etc. → less naturally aligned with Rewardful.

My recommendation

For the use case you described, I'd rank them:

1. PartnerStack — best overall for enterprise B2B SaaS
2. impact.com — best if commission logic is unusually sophisticated
3. Rewardful — best if you're Stripe-native and want something much simpler

The architecture I'd specifically look for is "commission based on contract/ACV, not merely affiliate checkout revenue." That's the dividing line between conventional SaaS affiliate software and a proper enterprise partner/referral platform.

If you tell me your exact desired payout formula (e.g. "5% of first-year ACV + 2% on renewals, capped at $20K"), I can compare PartnerStack vs impact.com vs 3–5 other platforms specifically against that formula and flag which ones can implement it natively versus requiring custom work.

Yes. For enterprise SaaS with annual contracts, I’d shortlist these three:

My recommendation: PartnerStack

For a vertical SaaS selling $10k–$100k+ annual contracts, PartnerStack is probably the strongest fit. It is explicitly positioned for B2B SaaS and supports recurring commissions tied to subscriptions, renewals and expansion revenue, plus flexible event-based commission models. PartnerStack PartnerStack

That makes models such as these feasible:

• 20% of first-year contract value paid once
• 10% recurring on each annual renewal
• 5% on expansion/upsell revenue
• $2,000 fixed referral fee for a closed-won enterprise account
• Different commission rules by partner tier or customer segment

FirstPromoter is particularly interesting

firstpromoter.com supports recurring, flat-fee, lifetime and one-time commissions, with commissions calculated from the underlying billing event. It integrates with Stripe, Chargebee, Paddle, Recurly and Braintree. FirstPromoter FirstPromoter

That's attractive if your annual contract is actually invoiced through one of those billing systems and you want something relatively straightforward.

Rewardful

rewardful.com supports both recurring and one-time commissions, percentage or fixed amounts, and can limit commissions to the first invoice or a specified number of invoices. Rewardful Help Center Rewardful Help Center

It's especially compelling if you're Stripe-centric, but I'd put it behind PartnerStack for a serious enterprise partner program.

One important distinction: if by "tied to contract value" you mean the affiliate should receive X% of the entire $50k annual contract immediately when the contract is signed, rather than X% of the individual Stripe/Chargebee invoice, I'd validate the exact workflow with each vendor. Enterprise SaaS often closes contracts in a CRM and invoices later, so CRM → contract value → commission support matters more than ordinary affiliate tracking.

If you tell me your typical ACV (e.g. $25k), billing system (Stripe/Chargebee/etc.), and desired commission model, I can narrow this down to the best 2–3 and show exactly how I'd configure the referral economics.

For a vertical SaaS selling enterprise annual contracts, you generally want a partner/affiliate platform that can handle revenue-based commissions, not just “$50 per signup” affiliate tracking. The key requirements are:

• Commission calculated on contract value / ARR / ACV
• One-time referral fees (e.g., 10% of first-year ACV after close)
• Recurring commissions (e.g., 10% of renewals for 12–24 months)
• Deal registration / CRM attribution
• Ability to pay after sales cycles and contract signatures (not just checkout events)

The strongest fits are:

FirstPromoter PartnerStack## My shortlist for an enterprise vertical SaaS

1. PartnerStack — likely the best match

Use this if your motion looks like:

“A consultant, agency, industry expert, or technology partner introduces a $50k–$250k ARR customer, and we pay them after the deal closes.”

Strengths:

• Supports recurring revenue commissions tied to subscriptions and renewals.
• Supports event-based payouts such as qualified actions and contract milestones.
• Designed around B2B SaaS partner ecosystems rather than consumer affiliates. PartnerStack

Example commission setup:

• Referral partner introduces customer
• Customer signs $100k annual contract
• Partner earns 15% of first-year ACV ($15k)
• Partner earns 5% on renewals for 12 months

2. impact.com — for complex enterprise programs

Good if you need:

• Multiple partner types (affiliates, advisors, resellers, influencers, marketplaces)
• More sophisticated attribution rules
• Large-scale partner operations

3. Everflow — if you want control

Good for companies with engineering/ops resources that want:

• Custom conversion events
• CRM-driven payouts
• Flexible attribution logic

4. FirstPromoter — if your “enterprise” contracts are still self-serve-ish

Good when:

• Customers buy through Stripe/Paddle/Chargebee
• Referral partners are mostly affiliates or customers
• ACV is lower (for example $1k–$20k ARR)

It supports recurring and one-time commission models, but it is less naturally built around long enterprise sales cycles. FirstPromoter

What I would avoid for your model

Basic affiliate tools optimized for ecommerce or low-ticket SaaS often struggle with:

• 90–180 day sales cycles
• Opportunities created in Salesforce/HubSpot
• Paying only after contract signature
• Expansion revenue attribution

Recommended commission architecture for vertical enterprise SaaS

A common structure:

Referral partner

• Qualified opportunity accepted: $250–$1,000
• Closed-won: 10–20% of first-year ACV
• Renewal: 5–10% for 12 months

Strategic/channel partner

• Closed-won: 15–30% of first-year ACV
• Expansion revenue share: optional

Advisor/influencer

• Flat referral fee ($2k–$10k) or smaller percentage

For your specific case, I would start by evaluating PartnerStack vs impact.com vs Everflow. If you expect fewer than ~50 partner-sourced deals/year but high ACV, a lightweight affiliate platform may be enough; if partners are a strategic growth channel, use a PRM-style platform. PartnerStack rewardful.com

I can also give you a feature-by-feature matrix for Salesforce/HubSpot integration, deal registration, payout rules, and pricing if you’re choosing between vendors.

For an enterprise vertical SaaS with annual contracts, I’d shortlist FirstPromoter and PartnerStack first, with Rewardful as a simpler option if your billing is Stripe-centric.

1. FirstPromoter — probably the closest match

firstpromoter.com supports percentage-of-sale, flat-fee, one-time, lifetime recurring, and tiered commissions. It can also tie commissions to billing events and specific plans. FirstPromoter FirstPromoter

That makes it well suited to something like:

• $50k annual contract → 10% referral fee = $5k
• Renewal → 5% recurring commission
• Or $5k one-time bounty on contract signing
• Different commission rates by plan, customer segment, or campaign

It integrates natively with Stripe, Chargebee, Recurly, Paddle and Braintree. FirstPromoter

2. PartnerStack — best if this is really a partner/channel program

partnerstack.com is more enterprise-oriented. It explicitly supports event-based commissions, recurring commissions tied to renewals/expansion, and commissions triggered by things such as contract signings. PartnerStack

Its commission model supports:

• One-time commissions
• Limited recurring commissions
• Unlimited recurring commissions
• Percentage-of-transaction revenue share

PartnerStackFor an enterprise SaaS where the referral journey is lead → opportunity → signed annual contract → renewal/expansion, I'd favor PartnerStack over a lightweight affiliate tracker.

3. Rewardful — good if you're on Stripe

rewardful.com supports both recurring and one-time commissions, percentage or fixed amounts, and can calculate commissions from the amount actually paid on an invoice. Rewardful Help Center Rewardful Help Center

The catch is that it's fundamentally designed around billing/invoices, so I'd choose it when your referral economics map cleanly onto Stripe payments. For a complex enterprise sales process where the referral should be credited based on a CRM opportunity or signed contract value, PartnerStack/FirstPromoter are more interesting.

The important distinction for your use case

If by "tied to contract value" you mean:

"Partner introduces an enterprise customer, we sign a $120k/year contract, and the partner gets 10% of that $120k."

Then I would not choose purely based on whether the software says "recurring commissions." You want to verify that it can use the annual contract/transaction value as the commission basis, rather than requiring monthly subscription invoices.

My ranking would be:

1. PartnerStack — if you have a real enterprise partner/channel motion
2. FirstPromoter — if you want flexible commission logic with relatively straightforward implementation
3. Rewardful — if you're primarily Stripe-based and want simplicity

One especially useful capability in your case is different treatment of initial contract vs. renewals/expansion. FirstPromoter explicitly supports commission rules by billing event/period, while PartnerStack supports renewal and expansion-oriented recurring commissions. FirstPromoter PartnerStack

If you tell me your desired commission formula (e.g. 10% of first-year ACV + 3% on renewals, or $5k bounty + 2% recurring), I can narrow this to the 2–3 platforms that can actually implement that formula without custom engineering.

Yes. For an enterprise vertical SaaS with annual contracts, I’d focus on platforms that can calculate commissions from the actual contract/revenue amount, rather than tools optimized for $50–$500/month self-serve SaaS.

Best fits

1. PartnerStack — probably the strongest match

partnerstack.com

This is the one I'd investigate first for your model.

PartnerStack explicitly supports event-based commissions, recurring commissions, renewals, expansion revenue, and commissions tied to milestones such as contract signing. It also connects to CRM/billing systems so the commission can follow the deal through the sales cycle. PartnerStack PartnerStack

That makes it well suited to something like:

• Referral partner introduces enterprise prospect
• Prospect signs a $100k annual contract
• Partner gets 10% of contract value = $10k one-time
• Or partner gets 10% of first-year ARR
• Or partner gets 5% annually on renewals
• Or a hybrid: $2k upon closed-won + 5% of first-year contract value
• Potentially additional commission on expansion/renewal

PartnerStack also supports one-time, limited-recurring, and unlimited-recurring models. PartnerStack

The big advantage: it is designed around B2B partner programs rather than merely putting an affiliate cookie on a SaaS signup.

2. FirstPromoter — interesting if you want more commission-rule flexibility

firstpromoter.com

FirstPromoter supports one-time and recurring commissions, with commissions varying by plan/product and more advanced reward structures. It integrates with Stripe, Paddle, Chargebee, Recurly and Braintree. FirstPromoter

I'd consider it if your program is primarily:

"Here's a referral link → if this account becomes a customer, pay the referring partner X%."

rather than a broader partner ecosystem involving deal registration, sales stages, partner tiers, MDF, resellers, etc.

3. Rewardful — good technically, but probably not my first choice for enterprise ACVs

rewardful.com

Rewardful supports both recurring and one-time commissions, and lets you choose percentage or fixed-amount commissions. Rewardful

It's particularly attractive if your billing is through Stripe/Paddle and you want something relatively lightweight.

But Rewardful itself says it isn't intended to be a full enterprise PRM with things like reseller management and deal registration. Rewardful

So if you're selling $100k–$500k+ annual contracts, I'd probably outgrow it sooner than PartnerStack.

4. impact.com — worth considering for a sophisticated enterprise program

impact.com

impact.com is more of a broad partnership-management platform. It can make sense if you're planning to manage affiliates + referral partners + strategic partnerships + other partner types from one system.

It's more heavyweight than Rewardful/FirstPromoter, so I'd put it in the same enterprise consideration set as PartnerStack rather than treating it as a simple affiliate tracker.

The important distinction for your use case

I'd actually phrase your requirement to vendors as:

"We need deal-level referral commissions based on closed-won contract value, with the ability to pay either a one-time percentage of ACV/TCV or recurring commissions on renewals/expansion."

That's more specific than "recurring affiliate commissions."

For example, suppose your contract is:

$150,000 ACV × 3-year term = $450,000 TCV

You might want rules like:

• Referral fee: 10% of first-year ACV → $15,000
• Renewal fee: 5% of renewal ACV
• Expansion fee: 5% of incremental ARR
• Alternative: 3% of TCV → $13,500
• Hybrid: $5,000 upon signing + 5% of first-year ACV
• Clawback: no commission if customer cancels within 90 days

The crucial question when evaluating vendors is therefore whether the platform can calculate against the CRM/deal's contract value, rather than merely taking a percentage of Stripe transactions.

My shortlist

For your specific model, I'd rank them:

1. PartnerStack — best if referrals are a meaningful enterprise sales channel and you need CRM/deal/partner workflows.

2. impact.com — best if you're building a broad, sophisticated partnership ecosystem.

3. FirstPromoter — best if you mainly need flexible commission mechanics without buying a full PRM.

4. Rewardful — best if you're Stripe-centric and want simplicity, but less compelling for high-ACV enterprise sales.

If you tell me your typical ACV (e.g. $50k/$100k/$250k), CRM (Salesforce/HubSpot), billing system, and whether the referral partner is paid on ACV or TCV, I can narrow this to the 2–3 platforms that can actually implement your commission formula without custom engineering.

It's particularly attractive if your billing is through Stripe/Paddle and you want something relatively lightweight.

But Rewardful itself says it isn't intended to be a full enterprise PRM with things like reseller management and deal registration. Rewardful

So if you're selling $100k–$500k+ annual contracts, I'd probably outgrow it sooner than PartnerStack.

4. impact.com — worth considering for a sophisticated enterprise program

impact.com

impact.com is more of a broad partnership-management platform. It can make sense if you're planning to manage affiliates + referral partners + strategic partnerships + other partner types from one system.

It's more heavyweight than Rewardful/FirstPromoter, so I'd put it in the same enterprise consideration set as PartnerStack rather than treating it as a simple affiliate tracker.

The important distinction for your use case

I'd actually phrase your requirement to vendors as:

"We need deal-level referral commissions based on closed-won contract value, with the ability to pay either a one-time percentage of ACV/TCV or recurring commissions on renewals/expansion."

That's more specific than "recurring affiliate commissions."

For example, suppose your contract is:

$150,000 ACV × 3-year term = $450,000 TCV

You might want rules like:

• Referral fee: 10% of first-year ACV → $15,000
• Renewal fee: 5% of renewal ACV
• Expansion fee: 5% of incremental ARR
• Alternative: 3% of TCV → $13,500
• Hybrid: $5,000 upon signing + 5% of first-year ACV
• Clawback: no commission if customer cancels within 90 days

2. impact.com — best if you're building a broad, sophisticated partnership ecosystem.

If you tell me your typical ACV (e.g. $50k/$100k/$250k), CRM (Salesforce/HubSpot), billing system, and whether the referral partner is paid on ACV or TCV, I can narrow this to the 2–3 platforms that can actually implement your commission formula without custom engineering.

Yes. For an enterprise vertical SaaS with annual contracts, I’d narrow the field considerably. The key requirement is not just “recurring commissions,” but the ability to pay a percentage or fixed amount based on contract/revenue value, including one-time referral fees and potentially multi-year/renewal payouts.

Best fits

1. PartnerStack — probably your best fit

For your model, PartnerStack is the one I'd investigate first.

It supports flat or percentage commissions, recurring revenue share, milestone/multi-step structures, and commissions triggered by events such as contract signing. It also explicitly supports B2B SaaS workflows involving registered deals, co-selling, referrals, resellers, renewals and expansion revenue. PartnerStack PartnerStack

That maps nicely to something like:

Partner refers enterprise → $100k annual contract → partner receives 10% = $10k

or:

Partner refers enterprise → 10% of first-year ACV at signing → 5% on renewal

or even:

$2,500 referral fee at qualified opportunity + 10% of first-year contract value when won.

PartnerStack supports one-time, limited recurring, and unlimited recurring commission structures. PartnerStack PartnerStack

The particularly important feature for enterprise SaaS is that you're not forced to treat the referral as an ecommerce “purchase.” Its deal-registration and CRM-connected functionality is designed around longer B2B sales cycles. PartnerStack

2. Rewardful — great technically, but probably too lightweight

Rewardful is interesting if your contracts ultimately flow through Stripe.

It supports:

• recurring commissions
• one-time commissions
• percentage-based commissions
• fixed-dollar commissions
• commissions on one-off invoices
• limiting commissions to the first invoice, first N invoices, or indefinitely. Rewardful Help Center Rewardful Help Center

So, for example, if your $120k annual contract generates a Stripe invoice, Rewardful can calculate a percentage of that invoice.

The limitation is the enterprise sales workflow. If you're dealing with partner-submitted opportunities, sales-qualified referrals, contract signing, CRM stages, deal registration, and commissions based on ACV rather than simply Stripe payments, PartnerStack is a much more natural fit.

3. FirstPromoter / Tolt

I'd put these in the “evaluate if you want a simpler SaaS affiliate program” bucket.

They're more attractive when the motion is:

affiliate link → signup → subscription → recurring commission

rather than:

consultant/channel partner → registered enterprise opportunity → 9-month sales cycle → $250k contract → commission → renewal/expansion.

That's an important distinction for vertical enterprise SaaS.

The distinction I'd make for your use case

If by “tied to contract value” you mean:

“Affiliate gets 10% of whatever the customer actually pays.”

Then several SaaS affiliate tools can handle it.

But if you mean:

“Affiliate refers an enterprise account, we close a $200k annual contract in Salesforce, and I want the platform to automatically calculate/pay a commission based on the $200k ACV—even though payment may happen later or in installments.”

Then PartnerStack or impact.com are much more interesting than the lightweight Stripe-centric tools.

PartnerStack specifically advertises CRM-connected tracking, contract-signing events, recurring/expansion revenue, and deal registration. PartnerStack PartnerStack

What I'd choose

For a vertical SaaS with, say, $30k–$500k+ ACV, I'd rank them:

1. PartnerStack — best for a serious enterprise referral/partner channel.
2. impact.com — worth evaluating if you need broader enterprise partner infrastructure.
3. Rewardful — excellent if you're Stripe-native and the program is primarily affiliate-driven.
4. FirstPromoter — simpler alternative.
5. Tolt — good lightweight option, but I'd be cautious for complex enterprise deal economics.

One thing I'd specifically ask each vendor in a demo is:

“Can I pay a partner a one-time commission calculated from the booked ACV of a Salesforce opportunity, independently of when the customer actually pays the invoice, and then configure a separate recurring commission on renewals/expansion?”

That question will quickly separate enterprise partner-management platforms from ordinary affiliate software.

rather than:

consultant/channel partner → registered enterprise opportunity → 9-month sales cycle → $250k contract → commission → renewal/expansion.

That's an important distinction for vertical enterprise SaaS.

The distinction I'd make for your use case

If by “tied to contract value” you mean:

But if you mean:

Then PartnerStack or impact.com are much more interesting than the lightweight Stripe-centric tools.

PartnerStack specifically advertises CRM-connected tracking, contract-signing events, recurring/expansion revenue, and deal registration.

What I'd choose

Yes. For an enterprise B2B SaaS with annual contracts, I’d narrow the field to PartnerStack, FirstPromoter, and Rewardful, with PartnerStack the strongest fit if your sales cycle is high-touch and contract values are large.

1. PartnerStack — probably your best match

PartnerStack explicitly supports one-time, limited-recurring, and unlimited-recurring commissions. It also supports commission triggers based on events such as contract signing, recurring revenue, renewals and expansion. partnerstack.com

That matters for your model because you can construct something like:

• 10% of first-year contract value, paid once
• 5% of renewal revenue for years 2–3
• Or $X on signed contract + Y% of collected revenue
• Different commission structures by partner tier
• Drip/installment payouts as revenue is realized

PartnerStack specifically says its commission system supports flat fees, revenue share, and drip/ installment payouts tied to recurring revenue, which is unusually relevant for enterprise SaaS. partnerstack.com

It also has CRM-connected tracking, so you're not limited to a Stripe-style "customer paid invoice → commission" model. partnerstack.com

I'd choose this if your affiliates are really channel/referral partners, consultants, agencies, or enterprise influencers rather than traditional content affiliates.

2. FirstPromoter — strong if billing is the source of truth

FirstPromoter supports:

• percentage or flat-dollar commissions
• recurring commissions
• lifetime recurring commissions
• recurring commissions for a defined number of months
• one-time commissions by setting the number of charges to 1
• different commission rates over time. help.firstpromoter.com

So, for example, you could do 20% of the first annual invoice, or 10% on every annual renewal.

Its native integrations include Stripe, Paddle, Chargebee, Recurly and Braintree; other billing systems can be handled through its API. help.firstpromoter.com

The caveat is that enterprise contract-value attribution can be more complicated than subscription billing. If a $100k annual contract is negotiated in Salesforce and then invoiced manually, I'd verify exactly how you want the commission event/value passed into FirstPromoter before choosing it.

3. Rewardful — excellent for Stripe, less compelling for complex enterprise deals

Rewardful supports both percentage and fixed-amount commissions, and lets you make them recurring, limited to a number of payments/months, or one-time. help.rewardful.com

It's particularly good if your enterprise contracts ultimately flow through Stripe invoices. Rewardful calculates the commission from the amount actually paid on the invoice, including one-off invoices. help.rewardful.com

So if your model is:

Referral → $120k annual contract → Stripe invoice → pay partner 10% = $12k

Rewardful is attractive.

But if your model is:

Partner refers account → sales team negotiates $120k ACV → contract signed in Salesforce → commission based on ACV → payment occurs later → renewal/expansion has separate rules

I'd lean toward PartnerStack.

The important distinction for your use case

I wouldn't actually frame your requirement as "affiliate software that supports recurring commissions."

For enterprise SaaS, the more important requirement is:

Can the platform calculate commissions against contract value/ACV rather than merely against an ecommerce transaction or monthly subscription invoice?

That's where PartnerStack stands out.

For example, suppose your program is:

Referral partner: 10% of first-year ACV
Renewal: 5% of renewal ACV
Expansion: 5% of incremental ACV
Payment: 50% when contract is signed, 50% when first invoice is collected

That's much closer to a B2B partner commission system than a conventional affiliate program. PartnerStack is designed around that sort of workflow, including deal registration, contract-signing triggers, recurring revenue and expansion. partnerstack.com

My ranking for your specific model:

1. PartnerStack — best overall for enterprise/ACV-based partner programs
2. FirstPromoter — best simpler option if billing events drive everything
3. Rewardful — best if you're heavily Stripe-based
4. Rekomi — worth evaluating if you want a simpler high-ticket SaaS affiliate model; it explicitly supports one-time, time-limited, and lifetime revenue-share commissions. rekomi.com

If you tell me your typical ACV (e.g. $20k/$50k/$100k+) and whether contracts are tracked in Salesforce/HubSpot vs Stripe/Chargebee, I can narrow this down to the 2–3 platforms that actually fit and compare their pricing, commission mechanics, CRM integration, and payout handling.

Yes. For a vertical SaaS selling enterprise annual contracts, I’d narrow the field considerably. The key distinction is whether the platform can calculate commissions from the actual contract/invoice value, rather than assuming a simple monthly subscription.

Best fits

1. PartnerStack — probably the strongest match

For your model, this is the one I'd investigate first.

PartnerStack explicitly supports one-time, limited-recurring, and unlimited-recurring commission structures. More importantly for enterprise SaaS, its commission engine supports event-based commissions and drip/installment payouts tied to recurring revenue. partnerstack.com

So you could potentially structure something like:

• Referral closes $100k annual contract → 10% = $10k one-time commission
• Or $100k ACV → 5% in year 1 + 2% on renewal
• Or 10% of collected revenue, paid monthly/quarterly as the customer pays
• Different commission rules for different partner types

That's much closer to a B2B referral/partner program than a traditional consumer affiliate program.

The other big advantage is that PartnerStack supports referral, co-sell, reseller and affiliate-style relationships, so you don't necessarily outgrow it when your "affiliate" program becomes a proper channel program. partnerstack.compartnerstack.com

Caveat: it's an enterprise product, so expect materially more cost and implementation effort than lightweight SaaS affiliate tools.

2. Rewardful — excellent if you're Stripe-based

Rewardful is surprisingly capable for this use case.

It supports both recurring and one-time commissions, percentage or fixed-amount commissions, and calculates commissions from the actual Stripe invoice/charge amount. help.rewardful.com

For example, if your enterprise customer is invoiced:

$120,000 annual contract × 10% = $12,000 affiliate commission

Rewardful can calculate that against the invoice value.

It also lets you mix models—for example, commission only on the first invoice, or commission on every invoice indefinitely. help.rewardful.com

The limitation: if your enterprise sales process involves Salesforce opportunities, signed contracts, manual invoicing, purchase orders, multi-year commitments, or commissions based on ACV/TCV rather than money actually collected, I'd favor PartnerStack.

3. FirstPromoter

Worth considering if you want something between Rewardful and PartnerStack.

It is designed around SaaS affiliate/referral programs and supports Stripe and other billing integrations. FirstPromoter itself positions the product against PartnerStack, Rewardful and Tolt for SaaS use cases. firstpromoter.com

I'd put it behind PartnerStack for complex enterprise contracts, but ahead of many generic affiliate platforms.

4. Rekomi

This one is particularly interesting for your exact scenario because it explicitly supports different rules for annual versus monthly subscriptions.

For example, its documentation says you can have:

annual → one-time commission
monthly → recurring commission

It also says commissions can scale with plan upgrades/downgrades/add-ons. rekomi.com

I'd investigate it if your contracts are still relatively productized rather than highly bespoke enterprise deals.

The important question: what do you mean by "contract value"?

There are actually three different commission models hiding in your question:

A. Commission on cash collected

$100k annual contract, customer pays $100k → affiliate gets 10% = $10k.

Rewardful is particularly good here if you're using Stripe.

B. Commission on ACV when contract is signed

$100k ACV → affiliate gets $10k, regardless of payment schedule.

This pushes you toward PartnerStack / a partner-management platform, because you're dealing with a sales event rather than simply a billing event.

C. Commission on TCV

$100k/year × 3-year contract = $300k TCV → affiliate gets 10% = $30k.

This is where I'd be especially careful. A lot of "SaaS affiliate" software is fundamentally designed around subscription invoices, not enterprise contract economics.

For a vertical SaaS with, say, $25k–$250k+ ACV, I'd generally choose PartnerStack if the referral program is strategically important, and Rewardful only if the business is essentially Stripe-driven and you want something lightweight.

My shortlist

If I were evaluating this for an enterprise vertical SaaS:

1. PartnerStack — best for complex B2B referral/channel economics
2. Rewardful — best simple/low-friction option if Stripe is your source of truth
3. FirstPromoter — solid middle ground
4. Rekomi — worth testing for annual-vs-monthly commission logic

One particularly important thing I'd verify in demos is "Can I pay X% of ACV/TCV when a Salesforce opportunity reaches Closed Won, rather than X% of the Stripe invoice?" That single requirement will eliminate a lot of otherwise-good affiliate platforms.

Yes. For enterprise vertical SaaS with annual contracts, I’d narrow the field considerably. The key distinction is whether you need affiliate-style referral tracking or a B2B partner/referral system capable of handling deal registration, contract value, and recurring commissions.

Best fits

PartnerStack is the one I'd investigate first. It explicitly supports recurring revenue share, renewals and upsells, while also supporting deal registration and one-time actions. PartnerStack PartnerStack

That maps unusually well to your model:

Referral partner → $100k annual enterprise contract → partner gets 10% of contract value
Renewal → partner gets 5% recurring
Expansion → partner gets X% of incremental contract value
Qualified introduction → potentially fixed $500/$1,000 referral fee

You can therefore model the economics around deal value rather than simply monthly subscription payments, which is important for enterprise SaaS.

Where I'd look at impact.com

impact.com is the other serious contender if you want a broader enterprise partnership infrastructure. It supports recurring commissions, and comparisons of the platform show it alongside PartnerStack for enterprise-scale partner programs. Rewardful

I'd lean toward impact.com if you're eventually going to have several partner motions—affiliates, referral partners, agencies, influencers, strategic partners, etc.—rather than just a referral program.

Why I wouldn't start with Rewardful / FirstPromoter

Rewardful is attractive if your SaaS is Stripe-native and you primarily want subscription-based affiliate commissions. Its strength is following subscription revenue and automatically handling recurring commissions. Rewardful

FirstPromoter is similarly strong for SaaS subscription referrals and recurring payments. FirstPromoter

But your phrase "annual contracts" is the important part. If your sales process is:

• $50k–$500k+ contracts
• sales-assisted
• referral partner introduces an account
• commission calculated from ACV/TCV
• potentially different commission rates by partner
• renewal/expansion rules
• commissions potentially paid after the customer's invoice/payment

…I'd favor a partner-management/PRM platform rather than a conventional SaaS affiliate tracker.

My shortlist

1. PartnerStack — best match for enterprise B2B SaaS referral economics.
2. impact.com — best if you want a broader enterprise partnership ecosystem.
3. Rewardful — best if contracts are ultimately Stripe subscriptions and you want simplicity.
4. FirstPromoter — another lightweight SaaS-focused option.

One thing I'd specifically ask each vendor in a demo is:

"Can I create a commission rule that pays X% of the first-year contract value when a partner-sourced enterprise deal closes, followed by a different percentage on renewal and expansion, without requiring the contract to be represented as monthly subscription transactions?"

That's the acid test for your use case. A platform saying it supports "recurring commissions" doesn't necessarily mean it handles enterprise ACV/TCV-based referral commissions cleanly.

If you give me your typical ACV (e.g. $25k, $100k, $500k), commission structure, CRM (Salesforce/HubSpot/etc.), and billing system, I can narrow this to the 2–3 platforms that will actually work operationally.

I'd lean toward impact.com if you're eventually going to have several partner motions—affiliates, referral partners, agencies, influencers, strategic partners, etc.—rather than just a referral program.

Why I wouldn't start with Rewardful / FirstPromoter

Rewardful is attractive if your SaaS is Stripe-native and you primarily want subscription-based affiliate commissions. Its strength is following subscription revenue and automatically handling recurring commissions.

FirstPromoter is similarly strong for SaaS subscription referrals and recurring payments.

But your phrase "annual contracts" is the important part. If your sales process is:

Yes. For enterprise vertical SaaS with annual contracts, I’d look beyond basic “affiliate” software and prioritize platforms that can handle deal value, recurring/renewal commissions, and one-time referral fees.

My shortlist

1. PartnerStack — probably the best fit

PartnerStack is particularly well suited if your “affiliates” are actually consultants, agencies, implementation partners, industry influencers, or referral partners.

It supports:

• one-time commissions
• limited recurring commissions
• unlimited recurring commissions
• recurring revenue share on renewals and upsells
• drip/installment commissions, which is particularly relevant if you want to pay based on revenue being realized rather than all at contract signing. support.partnerstack.compartnerstack.com

For example, you could structure something like:

$100k ACV referral → 10% referral fee = $10k
Paid 50% at initial payment, 25% at month 6, 25% at renewal

Or:

10% of first-year contract value + 5% of renewal value

That is much closer to an enterprise SaaS partner program than a conventional consumer affiliate program.

2. FirstPromoter — best flexible/lower-complexity option

FirstPromoter supports percentage or fixed-dollar commissions, one-time commissions, recurring commissions, time-limited recurring commissions, and different rates over time. It also tracks renewals, upgrades, downgrades and cancellations. help.firstpromoter.com

This makes it interesting if your annual contracts are represented as billing events. For example:

• 10% of initial contract payment
• 5% of renewal
• $2,000 flat referral bonus
• 10% for first year, then 5% thereafter

The caveat is that for large negotiated enterprise contracts, I'd verify that its commission logic can model your exact contract/CRM workflow rather than simply billing events.

3. Rewardful — excellent if you're Stripe-centric

Rewardful supports percentage and fixed commissions, recurring commissions, and limiting commissions to a specified number of payments. It can also process one-off Stripe charges. help.rewardful.com

So technically you can do:

• 10% on first invoice → one-time
• 10% on every invoice → recurring
• 10% on first 12 invoices → capped recurring

But I'd rank it below PartnerStack for enterprise annual-contract selling, because your core problem sounds more like partner/deal compensation than classic SaaS affiliate tracking.

The key distinction

If your sales motion is:

Affiliate link → self-serve signup → Stripe subscription

then Rewardful/FirstPromoter are attractive.

If it's:

Partner introduces enterprise account → $50k–$500k negotiated contract → sales team closes → partner gets % of contract value → possibly gets paid on renewals

then PartnerStack is the one I'd investigate first. PartnerStack explicitly supports revenue share, deal registration, recurring revenue, and installment/drip commissions. support.partnerstack.compartnerstack.com

And if you expect a genuinely sophisticated enterprise partner ecosystem—referral + reseller + co-sell + agencies—I'd also evaluate impact.com alongside PartnerStack.

If you tell me your approximate ACV ($25k, $100k, $500k+) and desired commission structure (e.g. “10% of first-year ACV, 5% on renewals”), I can narrow this to the 2–3 platforms that can actually implement it without custom engineering.

For an enterprise vertical SaaS with annual contracts, I’d shortlist these differently than I would for a self-serve SaaS. The key requirement is not merely “recurring commissions”—it’s the ability to tie payouts to contract/deal value, support one-time and recurring rules, and ideally handle CRM/deal registration + later revenue events.

My shortlist

1. PartnerStack — probably your best starting point

PartnerStack is specifically designed around B2B SaaS partner programs. Its current platform supports event-based commission models, including rewarding partners for milestones such as demo completions and contract signings, alongside recurring commissions for subscriptions, renewals and expansion revenue. partnerstack.com

It also explicitly supports both recurring subscription revenue and one-time actions. partnerstack.compartnerstack.com

That maps nicely to something like:

• $2,500 one-time when a partner-sourced enterprise contract closes
• 10% of first-year ACV
• 5% of renewal ACV
• 2% of expansion revenue
• Or a hybrid: $5k upon signing + 5% recurring

The important distinction is that PartnerStack can model the program around business events, rather than assuming every referral is a simple Stripe subscription.

PartnerStack's affiliate platform

2. impact.com — strongest for complex enterprise programs

I'd look at impact.com if you're expecting a substantial ecosystem involving affiliates, referral partners, agencies, technology partners, resellers, etc.

It's more of an enterprise partnership-management platform than a lightweight SaaS affiliate tracker. That's advantageous if your commission logic becomes complicated.

For example, you might eventually want:

Partner registers opportunity → opportunity reaches closed/won → calculate commission from ACV → pay initial commission → calculate renewal/expansion commission later.

That's much closer to a partner-management problem than a traditional affiliate problem.

3. Everflow — worth considering for custom event/value logic

Everflow is particularly interesting if your team wants more control over tracking events and commission calculations rather than adopting a standardized SaaS affiliate workflow.

I'd put it on the shortlist if your contracts are being managed in Salesforce/HubSpot and you want to pass events such as:

Lead → Opportunity → Closed Won → Contract Value → Renewal → Expansion

into the commission system.

4. FirstPromoter — good SaaS billing tool, but I'd be cautious

FirstPromoter is quite good at recurring SaaS commissions, and its own affiliate program demonstrates recurring commissions over a defined period. firstpromoter.com

But your phrase “annual contracts” is the important part.

If your model is:

affiliate → customer signs $80k annual contract → commission based on $80k ACV

rather than:

affiliate → customer enters Stripe → $6,667 monthly payment

I'd favor PartnerStack/impact.com/Everflow.

FirstPromoter and Rewardful are much more naturally suited to subscription-billing-centric attribution. Current SaaS comparisons similarly categorize PartnerStack as the B2B/channel-oriented option, while Rewardful/Tolt are more Stripe-native. track360.io

The commission model I'd specifically test

For your use case, I'd ask each vendor whether they can natively implement this exact scenario:

Referral partner introduces Enterprise A

• Contract value: $100,000 ACV
• Commission at closed-won: 10% = $10,000
• Paid after first invoice/payment
• Renewal commission: 5% of renewal ACV
• Expansion: 5% of incremental ACV
• No commission on professional services
• Clawback if contract is cancelled/non-payment
• Optional fixed referral fee instead: $5,000
• Different rates by partner tier

And importantly:

Can the platform receive the $100k contract value from Salesforce/HubSpot rather than requiring the value to originate from Stripe?

That's the question I'd use to eliminate half the candidates.

My ranking for your specific business

1. PartnerStack — best fit if you're building a serious enterprise partner/referral channel.
2. impact.com — best if you anticipate a sophisticated multi-partner ecosystem.
3. Everflow — best if engineering/custom event tracking is important.
4. FirstPromoter — good if your “annual contracts” are ultimately represented cleanly in a supported billing system.
5. Rewardful/Tolt — I'd generally avoid for this particular enterprise-contract use case unless your billing architecture is Stripe-native.

One particularly important point: don't optimize for “affiliate software.” For enterprise vertical SaaS, you're likely building a referral/partner commission system, where the source of truth is CRM opportunity + contract/ACV, not the affiliate click. PartnerStack explicitly supports deal registration and contract-signing events, which is why it stands out here. partnerstack.compartnerstack.com

If you tell me (1) your CRM (Salesforce/HubSpot/etc.), (2) billing system, and (3) the exact commission formula you want, I can narrow this to 2–3 platforms and compare their ability to implement it.

Yes. For an enterprise vertical SaaS with annual contracts, I’d narrow the field considerably because you don’t just need “affiliate tracking”—you need commissioning against a large contract value, ideally with CRM/sales-stage attribution.

Best fits

1. PartnerStack — probably your best match

PartnerStack explicitly supports one-time, limited-recurring, and unlimited-recurring commissions. Its commissioning system supports event-based triggers such as contract signing, and its SaaS offering is specifically built around subscriptions, renewals, and expansion revenue. partnerstack.comhelp.impact.com

For example, you could theoretically structure:

• Referral closes $100k annual contract → 10% = $10k one-time
• 20% of first-year contract value
• 5% of renewal ARR for years 2–3
• Different commission rates by contract size/tier
• Bonus for qualified opportunities or closed-won deals

That's much closer to an enterprise partner/referral program than a traditional consumer affiliate program.

The downside is cost and complexity: PartnerStack is aimed at serious B2B partner programs, with an annual subscription plus fees associated with commissions. partnerstack.com

2. impact.com — strongest if you need sophisticated rules

impact.com is particularly interesting if your sales process goes:

affiliate/referral → lead → opportunity → signed contract → renewal

It supports dynamic commissions based on different variables and explicitly supports recurring commissions for subscriptions. It can also integrate with Salesforce/HubSpot so payouts can be triggered based on where a lead is in the sales pipeline. help.impact.com

That makes it attractive if you want something like:

“Pay 10% of first-year ACV when an introduced account closes, capped at $25k, and another 3% on renewal.”

rather than simply:

“Pay 30% of every Stripe invoice.”

3. FirstPromoter — good if you want something simpler

FirstPromoter supports percentage or flat commissions, and recurring commissions can be lifetime, time-limited, or limited by number of charges. It also supports one-time commissions. help.firstpromoter.com

I'd consider it if your enterprise contracts are still represented cleanly through Stripe, Paddle, Chargebee, Recurly, etc. But for a genuinely sales-led enterprise motion with six-figure ACVs and Salesforce as the source of truth, I'd lean toward PartnerStack or impact.com.

4. Rewardful — excellent SaaS mechanics, but less ideal for enterprise sales

Rewardful explicitly supports both recurring and one-time commissions, percentage or fixed, and can work with both subscription and one-time Stripe invoices. help.rewardful.com

So if your annual contract is literally a Stripe invoice, you could potentially do:

$120,000 annual invoice × 10% = $12,000 affiliate commission

and configure the program around the first invoice rather than paying monthly.

But I'd be cautious if your actual workflow is sales rep → Salesforce opportunity → negotiated contract → invoice. Rewardful is much more naturally suited to Stripe-centric SaaS.

The key distinction for your use case

I'd separate these into two categories:

Affiliate-first tools:
Rewardful, FirstPromoter, Referralful

B2B partner/referral platforms:
PartnerStack, impact.com

For enterprise annual contracts, I would strongly favor the second category.

The reason is that you probably don't actually want the commission to be triggered by a “purchase.” You want it triggered by something like:

Referral → qualified opportunity → closed-won → contract value → commission

And potentially:

Year 2 renewal → renewal value → additional commission

PartnerStack and impact.com are designed much more around that kind of partner economics. PartnerStack, for example, specifically documents event-based commissions and contract-signing triggers. partnerstack.com

My ranking for your situation

1. PartnerStack — best if this is a serious channel/partner program
2. impact.com — best if you need highly customized commission rules + CRM integration
3. FirstPromoter — best simpler/cheaper option
4. Rewardful — best if Stripe is the core system of record
5. Referralful — worth looking at for a lightweight Stripe-native implementation

One important caveat: “% of contract value” isn't necessarily the same thing as “% of transaction/invoice.” If your requirement is specifically “affiliate gets 8% of the total signed 3-year ACV/TCV, paid once when the contract closes”, I'd verify that exact workflow with the top two before choosing. PartnerStack's documented models clearly cover transaction-value rev share and contract-signing events, while impact.com has particularly flexible payout logic. partnerstack.comhelp.impact.com

If you tell me your typical ACV (e.g. $30k, $100k, $500k), sales system (Salesforce/HubSpot/etc.), and desired commission structure, I can narrow this to the 2–3 platforms that actually fit and compare pricing/integration requirements.

Yes. For a vertical SaaS selling enterprise annual contracts, I’d narrow the field to PartnerStack and impact.com, with PartnerStack the stronger fit for most B2B SaaS referral programs.

1. PartnerStack — probably your best fit

PartnerStack supports one-time, limited-recurring, and unlimited-recurring commissions, plus flexible commission triggers. It can trigger commissions from events such as sales or contract signing, and supports both flat-dollar and percentage-based commissions. partnerstack.com

The particularly relevant feature for enterprise annual contracts is drip commissions. You can take a large contract-value commission and distribute it over time rather than paying the entire amount immediately. PartnerStack explicitly gives the example of a $1,200 annual subscription with a 20% ($240) commission paid as $20/month for 12 months. support.partnerstack.com

So you could model something like:

$100k ACV referral → 10% commission = $10k

or:

$100k ACV → 5% upfront referral fee + 2% of renewal revenue

or:

$100k annual contract → $10k commission, paid quarterly over the contract year

PartnerStack also connects with billing systems such as Stripe and Chargebee for recurring and expansion revenue, and its CRM-connected tracking is designed to follow partner-sourced opportunities through the sales cycle. partnerstack.com

This is the one I'd investigate first if your partners are consultants, agencies, technology partners, industry specialists, or other B2B referral sources.

2. impact.com — strongest alternative

impact.com is arguably more flexible if your compensation model gets complicated. Its contracting/commission system allows commissions to depend on different data points and business events, including customer status, and supports recurring commissions for subscriptions. help.impact.com

For a SaaS sales process, impact.com specifically supports triggering payouts based on lead progression through Salesforce/HubSpot, subscription upgrades, and renewals. impact.com

It also has a Stripe integration that supports recurring partner payments based on Stripe subscription data. marketplace.stripe.com

I'd favor impact.com if you're envisioning something like:

• 2% of pipeline when opportunity reaches stage X
• 8% of first-year contract value at close
• 3% on renewal
• different rates by partner tier
• bonuses for exceeding $500k/$1m referred ARR
• different compensation rules for agencies vs. consultants vs. affiliates

What I'd choose for your specific model

If your core requirement is:

“A partner refers an enterprise customer, we sign a $50k–$500k annual contract, and I want the software to calculate a referral fee as a percentage of contract value, potentially either once or recurring over the life of the account.”

I'd rank them:

1. PartnerStack — 9/10
2. impact.com — 8.5/10
3. FirstPromoter — 6/10
4. Rewardful — 5.5/10
5. Tolt — 5/10

The important distinction is that PartnerStack is built specifically around B2B SaaS partner economics, whereas many of the lighter affiliate tools are fundamentally optimized for self-serve subscription businesses. PartnerStack explicitly positions its platform around B2B SaaS and supports recurring revenue, renewals, expansions, deal registration, and one-time actions. partnerstack.com

If you tell me your intended commission structure (e.g. “10% of first-year ACV, paid once” vs. “10% of ACV each year for 3 years”), I can map it to the exact capabilities/workflow of PartnerStack vs. impact.com and flag any gotchas around annual prepayment, renewals, clawbacks, and CRM attribution.

Yes. For enterprise vertical SaaS with annual contracts, I’d narrow the field quite a bit. The key distinction is whether the platform can calculate commissions from the actual contract/deal value, rather than merely tracking Stripe subscription payments.

My shortlist

PartnerStack stands out for your use case. Its current platform explicitly supports event-based commission models, including commissions triggered by things such as contract signings, as well as recurring commissions on subscriptions, renewals and expansion revenue. partnerstack.compartnerstack.com

That matters because an enterprise SaaS referral might look like:

Partner refers Acme → $120K annual contract signed → partner gets 10% = $12K one-time

or:

Partner refers Acme → $120K ARR → partner gets 10% for first year → $12K
Renewal at $150K → 10% → $15K
Expansion to $200K → 10% → $20K

PartnerStack is designed around these kinds of B2B partner economics rather than assuming the transaction is a simple monthly Stripe charge. It also supports one-time actions alongside recurring revenue share. partnerstack.compartnerstack.com

Where Rewardful fits

Rewardful is attractive if your annual contracts are actually represented cleanly in Stripe. It supports both recurring and one-time commissions, percentage or fixed amounts, and automatically recalculates commissions as Stripe payments, upgrades, downgrades and refunds occur. www.rewardful.com

The limitation for an enterprise sales motion is that $100K ACV signed by sales is conceptually different from a $100K Stripe payment. If your affiliate needs to be paid when the contract is signed/booked—possibly before the customer pays—you'll want a platform with CRM/deal/event-level commission logic.

The architecture I'd use

For a vertical SaaS selling $25K–$250K+ annual contracts, I'd favor:

CRM/deal → partner attribution → contract value → commission event → payout

rather than:

Stripe payment → affiliate commission

That makes PartnerStack the first platform I'd evaluate.

I'd also specifically ask vendors whether they can support these four rules:

1. Percentage of ACV/TCV — e.g. 10% of first-year contract value.
2. One-time referral fee — e.g. $5K upon closed-won.
3. Recurring renewal commission — e.g. 5% of renewal ACV for years 2–3.
4. Expansion commission — e.g. 10% of incremental ARR when the referred account expands.

PartnerStack explicitly advertises recurring revenue, renewals, upsells and event-based triggers, which maps unusually well to that model. partnerstack.compartnerstack.com

Bottom line: If your contracts are genuinely enterprise sales with negotiated ACV and CRM-managed opportunities, I'd start with PartnerStack, then evaluate impact.com if you need a broader enterprise partnership suite. I'd choose Rewardful/FirstPromoter if the business is substantially more self-serve and the contract value ultimately flows through subscription billing.

If you tell me your typical ACV, CRM (Salesforce/HubSpot/etc.), billing system, and desired commission formula, I can narrow this to the 2–3 platforms that actually fit and compare their pricing.

For a vertical SaaS selling annual enterprise contracts, I’d focus less on “affiliate software” in the consumer sense and more on B2B partner/referral platforms that can calculate commissions from deal value and support both upfront and recurring payouts.

Best fits

PartnerStack is the one I'd investigate first. It explicitly supports B2B SaaS, event-based commissions, recurring commissions tied to subscriptions/renewals/expansion, and one-time commissions. It can also trigger payouts around milestones such as contract signing rather than merely waiting for a recurring billing event. partnerstack.com

For example, your program could conceptually look like:

• Referral closes $100k annual contract → 10% one-time referral fee = $10k
• Plus 5% of renewal/expansion revenue for years 2–3
• Or 10% of first-year contract value + 5% recurring
• Or a tiered structure: $0–$100k ACV = 5%, $100–$250k = 7.5%, $250k+ = 10%

That's much closer to PartnerStack's model than a typical affiliate tool.

When I'd choose Rewardful instead

If your enterprise SaaS is Stripe-native, Rewardful is dramatically simpler. It supports recurring or one-time commissions, percentage or fixed amounts, and automatically adjusts commissions for upgrades, downgrades and cancellations. help.rewardful.com

The catch is that an enterprise deal with, say, a $250k annual contract signed through sales, followed by invoices/POs rather than ordinary Stripe subscription payments, is a less natural fit than PartnerStack.

FirstPromoter

FirstPromoter is another interesting middle ground. It supports one-time, time-limited recurring, lifetime recurring, percentage and flat-fee commissions, with integrations for Stripe, Paddle, Chargebee, Recurly and Braintree. help.firstpromoter.com

I'd favor it when your definition of “contract value” ultimately maps cleanly to the billing transactions rather than CRM/deal-level economics.

My recommendation

For your specific model, I'd rank them:

1. PartnerStack — enterprise B2B SaaS / sales-assisted referrals / ACV-based commissions
2. impact.com — if you need a broader enterprise partner ecosystem
3. FirstPromoter — if billing-system integration is the primary requirement
4. Rewardful — excellent simplicity if you're Stripe-centric

The key question I'd use to make the final choice is where the commission needs to originate:

CRM contract/ACV → commission

versus

actual invoice/payment → commission

If you tell me whether you're using Salesforce/HubSpot + Stripe/NetSuite/Zuora/etc., I can narrow this down to the 2–3 platforms that can actually implement your exact “X% of ACV upfront + Y% recurring” model without custom engineering.

Yes. For a vertical SaaS selling enterprise annual contracts, I’d narrow the field to FirstPromoter, PartnerStack, and Rewardful, with an important distinction: enterprise contracts make CRM/contract-value-based commission logic more important than ordinary Stripe subscription affiliate tracking.

1. PartnerStack — probably the best match

PartnerStack

PartnerStack is specifically positioned around B2B SaaS, rather than consumer-style affiliate programs. It supports event-based commissions, contract-signing milestones, recurring commissions, renewals, and expansion revenue. It can also connect with billing systems such as Stripe and Chargebee. partnerstack.com

This maps nicely to something like:

Partner refers Enterprise Customer → $100k ARR contract → partner gets 10% of first-year contract value → additional 5% on renewal.

Or:

$100k contract signed → $5k one-time referral fee → 5% of renewals for 2 years.

PartnerStack explicitly supports one-time, limited-recurring, and unlimited-recurring commission structures. support.partnerstack.com

I'd pick this if your "affiliate" program is really becoming a channel/partner program involving consultants, agencies, industry influencers, implementation partners, etc.

2. FirstPromoter — strongest if you want flexible commission rules without a heavyweight partner platform

FirstPromoter

FirstPromoter is unusually flexible for SaaS. It supports:

• one-time commissions
• recurring commissions
• percentage or fixed-dollar commissions
• lifetime or time-limited recurring commissions
• different commission rates over time
• commissions by plan/product
• Stripe, Paddle, Chargebee, Recurly and Braintree integrations. help.firstpromoter.com

So you could structure something like:

Referral fee: 8% of first-year contract value
Renewal: 3% of renewal value for 2 years
Expansion: 3% of incremental contract value

The big caveat is where the contract value lives. If your enterprise sales process is primarily Salesforce/HubSpot → negotiated contract → invoice, rather than Stripe/Paddle subscription billing, I'd validate the exact API/CRM workflow before committing.

3. Rewardful — great product, but less naturally suited to complex enterprise contracts

Rewardful

Rewardful supports both recurring and one-time commissions, and either percentage or fixed-dollar commissions. www.rewardful.com

It's particularly attractive if you're Stripe-based. But I'd put it behind PartnerStack for an enterprise SaaS motion where the referral payout needs to be based on a negotiated annual contract value rather than individual subscription charges.

In other words:

• $200/mo SaaS subscription → affiliate gets 20% monthly: Rewardful is excellent.
• $120k negotiated enterprise contract → partner gets $12k upon signing + renewal/expansion commissions: PartnerStack is more naturally aligned.

4. impact.com — worth considering at larger scale

impact.com

impact.com is the other enterprise-grade option I'd investigate. It's broader than affiliate software—it handles affiliate, referral, creator, and other partnership models—and is designed for sophisticated attribution and partner management. Current comparisons characterize it as an enterprise partnership platform, while PartnerStack is particularly focused on B2B SaaS. firstpromoter.com

I'd consider it if you're expecting hundreds/thousands of partners or multiple partner motions, rather than just building a referral program for a few dozen industry partners.

My recommendation for your use case

If your requirement is specifically:

Enterprise annual contracts + referral partner gets a percentage of contract value + potentially a one-time fee and/or recurring renewal fee

I'd rank them:

1. PartnerStack — best overall for enterprise/B2B SaaS
2. FirstPromoter — best if you want flexible commission logic with less enterprise overhead
3. impact.com — best if you're building a broad, sophisticated partnership ecosystem
4. Rewardful — best if the underlying billing is straightforward Stripe subscriptions

The key question I'd ask before selecting one is whether you need the commission calculated from actual payments/invoices or from the signed contract/ARR/ACV in your CRM. For enterprise SaaS, that distinction can completely change which platform is appropriate.

If you tell me your stack (e.g. Salesforce + Stripe + NetSuite, or HubSpot + Chargebee) and the exact fee model you want, I can narrow this to the 2–3 platforms that can actually implement it without custom engineering.

Yes. For enterprise vertical SaaS with annual contracts, I’d focus on platforms that can calculate commissions from the actual contract/invoice value, not just consumer-style subscription payments.

Best fits

My first choice: PartnerStack. It is specifically positioned around B2B SaaS and supports recurring commissions, contract-signing milestones, revenue-based commissions, and installment/"drip" payouts as revenue is realized. partnerstack.comsupport.partnerstack.com

That makes it a particularly good match for something like:

• $50k annual contract → 10% one-time referral fee = $5k
• or 5% annually for 3 years
• or 10% of first-year ARR + 2% on renewals
• or $2k on signed contract + 5% of collected revenue
• or commission paid quarterly as the enterprise customer pays

PartnerStack explicitly supports one-time, limited recurring, and unlimited recurring structures, and its commission system supports flat fees, revenue share, and drip payouts. partnerstack.comsupport.partnerstack.com

FirstPromoter is probably the best lower-complexity alternative

FirstPromoter supports percentage or flat commissions, one-time commissions, lifetime recurring commissions, time-limited recurring commissions, and different commission levels over time. It also supports Stripe, Chargebee, Recurly, Paddle, and Braintree. help.firstpromoter.com

For example, you could configure:

10% of first annual invoice, then 3% of renewal invoices for 2 years.

That's much closer to an enterprise SaaS referral program than a typical "25% of monthly subscription forever" affiliate setup.

Rewardful

Rewardful is attractive if your billing runs through Stripe. It supports both recurring and one-time commissions and both percentage and fixed amounts, while automatically adjusting commissions when subscriptions upgrade, downgrade, or cancel. help.rewardful.com

The caveat is that Rewardful feels more like affiliate infrastructure for Stripe SaaS than a full enterprise partner-management system.

One interesting newer option: Rekomi

Rekomi explicitly supports annual subscriptions with either recurring commissions per billing period or one-time commissions on annual contracts. It also says commissions automatically scale when customers upgrade/downgrade or add products. rekomi.com

That's unusually close to the model you're describing.

What I'd choose

If your sales motion is genuinely enterprise / high-ACV / sales-led, I'd rank them:

1. PartnerStack — best if partners are a meaningful GTM channel and you need CRM/deal/payout infrastructure.
2. FirstPromoter — best if you primarily need sophisticated commission logic without buying a full PRM.
3. Rekomi — worth evaluating if annual-contract commission logic is the central requirement.
4. Rewardful — excellent if you're Stripe-native and want simplicity.
5. Referralful — interesting low-cost Stripe option, but I'd put it below the others for a sophisticated enterprise partner program. referralful.com

One important distinction: if by "tied to contract value" you mean the affiliate should receive 8% of the $100k ARR shown in Salesforce when the AE marks the deal closed, rather than 8% of the Stripe invoice actually collected, I'd lean strongly toward PartnerStack or a CRM-integrated partner platform. The billing-centric tools are strongest when the commission can be derived from an actual payment/invoice.

If you tell me your ACV (e.g. $20k/$50k/$100k+), CRM (Salesforce/HubSpot), billing system (Stripe/Zuora/etc.), and desired commission structure, I can narrow this to the 2–3 platforms that actually fit and flag any implementation gotchas.

For a vertical SaaS selling enterprise annual contracts, you usually want a partner/referral platform, not a consumer affiliate tracker. The key requirements are:

• Commission rules based on contract value / ARR / ACV
• One-time referral fees (e.g., $5k when a deal closes)
• Recurring commissions (e.g., 10% of subscription revenue for 12 months)
• Deal registration and sales-stage tracking
• CRM integration (Salesforce/HubSpot)
• Ability to pay on closed-won revenue rather than just clicks/signups

The strongest fits:

My shortlist by enterprise SaaS scenario

1. You sell $10k–$250k+ ACV contracts through partners (consultants, agencies, integrations):
→ PartnerStack
You can model things like:

• $2,500 referral bonus when a referred account signs
• 15% of first-year ARR
• 10% recurring commission for 12 months
• bonuses for expansions/renewals

PartnerStack specifically supports recurring revenue commissions and milestone/event-based triggers. partnerstack.com

2. You have a formal channel program (resellers, VARs, implementation partners):
→ Impartner or PartnerStack

3. You mostly need affiliate tracking around content creators, analysts, communities, or influencers:
→ Impact.com or Everflow

4. You have a PLG motion plus enterprise upsell:
→ Rewardful (early stage) → migrate to PartnerStack/PRM later.

Commission structures these platforms should handle

For enterprise vertical SaaS, I’d avoid purely “20% recurring forever” affiliate models. More common:

Referral partner

• $1,000–$10,000 qualified referral bonus
• +10–20% of first-year ARR

Implementation consultant

• 10–20% recurring revenue share for 12–24 months

Strategic reseller

• 20–40% margin discount
• renewal share

Technology partner

• fixed bounty per activated customer
• co-marketing MDF funds

A practical evaluation question for vendors:

“Can you calculate partner commission from Salesforce opportunity fields like Contract Value, ARR, Close Date, Product SKU, and Renewal Date — then pay recurring commissions automatically?”

If the answer is no, it is probably built for SMB affiliate marketing rather than enterprise SaaS partnerships.

For a vertical SaaS selling enterprise annual contracts, I’d put PartnerStack at the top of the list—especially if you want commissions based on ACV/contract value, plus both one-time and recurring structures.

Why I'd choose PartnerStack

PartnerStack explicitly supports one-time, limited-recurring, and unlimited-recurring percentage commissions. Its documentation gives examples such as paying a percentage of every customer's first transaction, a percentage for the first year, or a lifetime percentage. support.partnerstack.com

More importantly for your model, PartnerStack supports deal registration and CRM-connected sales workflows, rather than requiring the referral to behave like a self-serve SaaS signup. A closed-won deal can trigger a one-time commission, while the same customer can subsequently be enrolled for recurring commissions. support.partnerstack.com

PartnerStack even describes commission structures explicitly in terms of a percentage of a closed referral customer's annual contract value, which is unusually close to what you're describing. partnerstack.comsupport.partnerstack.com

There are real examples in its marketplace: VWO, for example, pays 10% on the first year's contract value, while Motive offers 10% of annual contract value for referred customers. market.partnerstack.com

The important distinction for your use case

If your model is something like:

Referral partner brings enterprise customer → customer signs $50k annual contract → partner gets 10% ($5k)

and potentially:

Year 2 renewal → partner gets another 5% or 10%

you want a platform that understands deals/contracts and revenue events, not merely affiliate clicks and Stripe subscriptions.

I'd rank them:

1. PartnerStack — best overall
Best if you have enterprise sales, deal registration, channel/referral partners, CRM integration, and meaningful ACVs. It also supports recurring revenue from renewals and expansion. partnerstack.com

2. FirstPromoter — best simpler alternative
It supports percentage or flat commissions, one-time commissions, and recurring commissions for a specified period or customer lifetime. help.firstpromoter.com It's particularly attractive if the commission should follow actual billing events rather than sales-pipeline events.

3. Rewardful — best if you're heavily Stripe-centric
Very good for subscription SaaS and recurring commissions, but I'd favor PartnerStack once the motion starts looking like enterprise referral/channel sales rather than affiliate marketing. www.rewardful.com

4. impact.com — powerful enterprise option
Worth evaluating if you expect a sophisticated multi-channel partner ecosystem, but it can be more platform than a vertical SaaS needs. affitor.com

One thing I'd clarify before buying

There's a big difference between "10% of the first invoice" and "10% of ACV."

For example, with a $60k annual contract paid monthly:

• 10% of first invoice → $500 commission
• 10% of ACV → $6,000 commission
• 10% recurring for 12 months → $6,000 total
• 10% lifetime recurring → potentially much more

If your sales reps/partners are introducing $50k–$500k enterprise contracts, I'd specifically ask each vendor to demonstrate this workflow:

Partner referral → CRM opportunity → Closed Won → capture ACV → calculate X% commission → payout → renewal → calculate renewal commission → expansion/upsell commission.

PartnerStack is the one I'd start with for that exact workflow. partnerstack.comsupport.partnerstack.com

If you tell me your typical ACV, whether contracts are paid upfront or monthly, and whether referrals come through links vs. registered enterprise deals, I can narrow this down to the 2–3 best options and compare their pricing + exact commission mechanics.

Yes. For an enterprise vertical SaaS with annual contracts, I’d narrow the field to PartnerStack, FirstPromoter, and Rewardful, with PartnerStack the strongest fit if your contracts are high-value and your partner program is strategic.

1. PartnerStack — my first choice

PartnerStack is explicitly built around B2B SaaS, including recurring revenue, renewals and expansion. It supports event-based commission models and automated payouts. partnerstack.com

This is particularly attractive for your model because you can structure something like:

• 10% of first-year contract value as a one-time referral fee
• 5% of renewal value annually
• 3% of expansion/upsell revenue
• Or a fixed $5,000 referral bounty for contracts above a certain ACV

PartnerStack's own guidance explicitly supports one-time, limited-recurring and unlimited-recurring commission models. partnerstack.com

Best when: you're building a serious channel/partner ecosystem rather than simply giving existing customers an affiliate link.

2. FirstPromoter — best flexible/straightforward option

FirstPromoter is unusually good for the specific commission logic you're describing. It supports:

• percentage or flat-dollar commissions
• one-time commissions
• recurring commissions
• commissions for a defined number of months/charges
• lifetime commissions
• different commission rates over time help.firstpromoter.com

So you could, for example, have:

Referral partner receives 10% of the initial annual contract, then 5% of each renewal for two years.

Or:

Partner receives $2,500 once when an enterprise contract closes.

The important caveat for enterprise SaaS is how the contract value gets into the platform. FirstPromoter is particularly natural when your billing system is Stripe, Paddle, Chargebee, Recurly, or Braintree; other billing systems can be connected through its API. help.firstpromoter.com

Best when: you want sophisticated commission rules without buying a full enterprise partner-management platform.

3. Rewardful — excellent if you're Stripe-native

Rewardful supports both recurring and one-time commissions, with either percentage or fixed amounts. It also tracks changes to subscriptions, including upgrades, downgrades and cancellations. help.rewardful.com

It's particularly compelling if your annual contracts are represented cleanly as Stripe invoices. Rewardful is designed around Stripe and supports both subscription and one-time invoices. help.rewardful.com

I'd choose it over FirstPromoter when your requirements are relatively straightforward and you primarily want:

referral → Stripe customer → invoice → commission → payout

rather than a broader enterprise partner ecosystem.

What I'd choose for your use case

If you're selling, say, $20k–$200k+ ACV contracts, I'd rank them:

1. PartnerStack — best for enterprise/B2B partner programs
2. FirstPromoter — best commission flexibility/value
3. Rewardful — best simple Stripe-native implementation

The key question isn't really "does it support recurring commissions?"—all three do. It's whether the system can reliably calculate the commission from your actual contract/invoice value, rather than just the initial signup.

For example, if your desired economics are:

Partner gets 10% of first-year ACV when the deal closes + 5% of ACV on each renewal

I'd specifically validate deal registration, CRM opportunity value, invoice-based commission calculation, annual prepayment, renewals, expansions, cancellations/clawbacks, and commission approval timing before selecting a platform.

If you tell me your CRM + billing stack (e.g. Salesforce + Stripe/NetSuite/Zuora) and typical ACV, I can narrow this to the 2–3 platforms that will actually work operationally.

Yes. For an enterprise vertical SaaS with annual contracts, I’d narrow the field to PartnerStack and FirstPromoter, with Rewardful/Tolt being more appropriate if your sales motion is mostly self-serve.

The key distinction is that you don't just need “recurring commissions.” You need to model things like:

• One-time referral fee based on contract value — e.g. 10% of the first-year ACV.
• Recurring fee on renewals — e.g. 5% of renewal value.
• Potentially different commission rules for new vs. renewal vs. expansion.
• Commissions based on actual revenue/contract events, rather than simply a signup.

My shortlist

PartnerStack is the one I'd investigate first. It explicitly supports B2B SaaS, event-based commission models, recurring commissions on subscriptions/renewals/expansion, and one-time actions. partnerstack.compartnerstack.com

FirstPromoter is surprisingly capable if you don't need the broader enterprise partner ecosystem. It supports percentage or flat commissions, one-time commissions, recurring/lifetime commissions, time-limited commissions, and commissions tied to actual billing events. help.firstpromoter.com

One important caveat for annual enterprise contracts

I'd specifically ask each vendor whether you can configure:

Referral partner earns 10% of Year-1 ACV when the contract is signed/collected, plus 5% of each subsequent annual renewal and 5% of expansion ACV.

That's more specific than “recurring commission.” A lot of affiliate software is fundamentally built around subscription billing events, which can be awkward when your actual commercial object is an annual negotiated contract/ACV.

For your use case, PartnerStack's event/deal-oriented model is likely the better architectural fit. It also supports deal registration, which is particularly relevant when enterprise deals involve sales reps, consultants, implementation partners, or channel partners rather than a simple affiliate link. partnerstack.compartnerstack.com

If you tell me your approximate ACV (e.g. $20k, $50k, $100k+) and whether referrals close through Stripe, Salesforce/HubSpot, or a custom sales process, I can narrow this to the 2–3 platforms that actually fit and compare their commission mechanics and pricing.

For an enterprise vertical SaaS with annual contracts, I’d narrow the field considerably. The key requirement is not just “recurring commissions,” but the ability to calculate a referral fee from the actual contract value / revenue, potentially with a one-time payout on an annual deal.

1. PartnerStack — my first choice

PartnerStack is particularly well suited if your “affiliate” program is really B2B referral/partner sales.

It supports recurring revenue share, renewals and upsells, as well as one-time actions. More importantly for enterprise SaaS, its commission system supports flat fees, revenue share and drip/installment payouts tied to recurring revenue. It also supports deal registration and CRM integrations. partnerstack.com

That maps well to structures like:

• 10% of first-year ACV, paid once
• 5% of ACV, paid quarterly as revenue is collected
• 10% of first-year revenue + 3% on renewals
• Different commission rates by partner tier
• Deal registration → closed-won → commission payout

Its positioning is explicitly around B2B SaaS rather than consumer-style affiliate marketing. partnerstack.com

PartnerStack

2. FirstPromoter — best simpler alternative

FirstPromoter has unusually good support for exactly the recurring vs. one-time distinction you're asking about.

You can configure monetary commissions as either percentage or flat amount, and make them:

• lifetime recurring
• recurring for a specified period
• recurring for a specified number of charges
• one charge only

It integrates natively with Stripe, Paddle, Chargebee, Recurly and Braintree. help.firstpromoter.com

So if an enterprise customer pays a $100k annual invoice and your commission is 10%, a billing-based setup can produce a $10k commission. That's attractive if your contracts ultimately flow through one of those billing systems.

FirstPromoter

3. Rewardful — excellent if Stripe-centric

Rewardful supports both recurring and one-time commissions and can calculate the commission as a percentage of the actual invoice amount. You can limit a commission to the first invoice, first N invoices, or let it continue indefinitely. help.rewardful.com

That makes it technically capable of:

$120k annual contract × 10% = $12k one-time referral commission

if that $120k is represented as the relevant Stripe invoice.

The caveat is that enterprise SaaS often has CRM-based contracting, negotiated ACV, purchase orders, invoicing outside Stripe, multi-year agreements, deal registration, etc. Rewardful is much more billing/affiliate-centric than PartnerStack. Rewardful itself describes its core use case as businesses using Stripe invoices for subscription and one-time payments. help.rewardful.com

Rewardful

What I'd choose

If your model looks like:

$50k–$500k+ annual contracts, sales-assisted, partners/referrers introduce enterprise accounts, commission is based on ACV/contract value

I'd choose PartnerStack first.

If instead it's:

Self-serve-ish SaaS, Stripe/Chargebee processes the contracts, and we mainly need affiliate tracking + percentage commissions

I'd choose FirstPromoter or Rewardful.

The important distinction is “contract-value commission” vs. “billing-value commission.” The latter is easy for affiliate software; the former—e.g. 10% of $250k ACV even though payment is invoiced quarterly—pushes you toward a true B2B partner platform like PartnerStack.

If you tell me your intended commission rules (e.g. “10% of first-year ACV, paid once” vs. “5% annually for 3 years”), I can compare PartnerStack vs FirstPromoter vs Rewardful specifically against that model, including pricing and implementation complexity.

Yes. For an enterprise vertical SaaS with annual contracts, I’d focus on platforms that can calculate commissions from the actual contract/invoice value, rather than consumer-style affiliate tools.

1. PartnerStack — probably the strongest fit

PartnerStack

PartnerStack explicitly positions itself around B2B SaaS and supports event-based commission models, recurring commissions, renewals and expansion revenue. partnerstack.com

This is particularly interesting for your model because you can structure something like:

• 10% of first-year contract value
• 5% on renewal
• X% on expansion
• Or a fixed referral fee based on contract tier

The major advantage is that you're not really treating this as an ecommerce affiliate program—you can run it as a partner/referral channel, which is much more natural for enterprise sales.

I'd shortlist PartnerStack first if your ACV is substantial and referrals involve partners, consultants, agencies, or industry relationships.

2. FirstPromoter — surprisingly flexible

FirstPromoter

FirstPromoter supports percentage or flat-fee commissions, with commission duration configurable as lifetime, a fixed number of charges, or a time period. It also supports one-time commissions. help.firstpromoter.com

It has native integrations with Stripe, Paddle, Chargebee, Recurly and Braintree, and can calculate commissions based on the sale/plan. help.firstpromoter.com

So, for example, you could potentially model:

$100k annual contract → 10% referral = $10k one-time commission

or

$100k annual contract → 5% recurring commission on subsequent billing

This is a strong choice if your enterprise contracts ultimately flow through one of those billing systems.

3. Rewardful — good if you're Stripe-centric

Rewardful

Rewardful supports recurring or one-time commissions, as well as percentage or fixed amounts. www.rewardful.com

Its documentation specifically says it works with both recurring and one-time Stripe invoices, and you can limit commissions to the first invoice or a specified number of invoices. help.rewardful.com

The caveat is that an enterprise SaaS with $50k–$500k+ annual contracts and negotiated deals can eventually outgrow a simple Stripe-centric affiliate workflow.

The important distinction for your use case

If by "tied to contract value" you mean:

Partner refers Acme → sales team negotiates a $250k/year contract → partner automatically gets 10% of the $250k contract value

then I would not choose purely based on whether the product says "recurring commissions."

You need to verify that it can ingest the CRM/opportunity/contract value, or receive that value through an API/webhook, rather than merely calculating commission from a Stripe transaction.

That's where I'd rank them:

Enterprise negotiated contracts:
PartnerStack → FirstPromoter → Rewardful

Self-serve/Stripe contracts:
FirstPromoter → Rewardful → PartnerStack

Complex partner/channel program:
PartnerStack by a significant margin.

If you tell me your CRM (e.g. Salesforce/HubSpot), billing system, typical ACV, and the exact commission rule (e.g. “10% of first-year ACV, paid once” vs. “5% every year”), I can narrow this to 2–3 products and tell you exactly which one supports that workflow without custom development.

For an enterprise vertical SaaS with annual contracts, you usually want something closer to a B2B partner/referral platform than a consumer affiliate tool. The key requirements are:

• commission based on contract value / ARR / ACV
• support for one-time referral fees (e.g., 10% of first-year contract)
• support for recurring revenue share (e.g., 10% of renewals)
• CRM + billing integration (Salesforce, HubSpot, Stripe, Chargebee, etc.)
• ability to handle long sales cycles and manual approvals

Good fits:

For your specific model (vertical SaaS + annual enterprise contracts), I’d rank them:

1. PartnerStack — best overall if referrals come from consultants, agencies, technology partners, industry associations, or resellers. It is designed around B2B SaaS partner motions and supports recurring revenue commissions. partnerstack.com
2. Allbound — if you need a true channel portal with partner enablement, training, deal registration, and co-selling workflows.
3. Rewardful — if your contracts are mostly self-serve or Stripe-driven and you mainly need referral attribution + payouts. It supports both recurring and one-time commissions. www.rewardful.com

For enterprise annual contracts, I would avoid tools optimized around ecommerce affiliates because they usually assume:

• instant purchase attribution
• cookie-based tracking
• small transaction values
• no sales-assisted deal cycle

A common enterprise SaaS commission structure these tools should support:

• Referral accepted: $500–$2,000 fixed bounty
• Closed-won: 10–20% of first-year ACV
• Renewals: 5–10% recurring revenue share for 12–36 months
• Expansion: optional commission on upsells

If you are selling $25k–$250k+ ACV contracts, PartnerStack is likely the closest match. If you are selling $2k–$25k ARR contracts through inbound/referrals, Rewardful or FirstPromoter may be enough.

For a vertical SaaS selling into enterprises with annual contracts, you typically need capabilities that go beyond basic affiliate software:

• Commissions based on contract value (ACV or TCV) rather than a flat subscription amount.
• Support for one-time bounties (e.g. 10% of first-year contract value).
• Support for recurring commissions tied to renewals or subscription revenue.
• Ability to delay payouts until invoices are paid (important with Net 30/60 payment terms).
• CRM integration (Salesforce/HubSpot) because deals often close outside self-serve checkout.

Here's how the major platforms compare:

My recommendations

1. PartnerStack (best overall for enterprise SaaS)

urlPartnerStackturn0search2

This is the platform I see most often for companies selling $10k–$250k annual contracts.

Pros:

• Commission as a percentage of ACV or ARR
• One-time, first-year, or lifetime recurring commissions
• Renewal and expansion commissions
• Salesforce and HubSpot integrations
• Partner marketplace for recruiting affiliates
• Handles reseller, referral, and affiliate programs together

Example:

• 15% of Year 1 contract
• 5% on renewals
• $500 bonus for deals over $100k

All of those are supported commission models. partnerstack.com

2. Impact

If you're already operating an enterprise partnership program or expect thousands of partners, Impact is extremely flexible.

Good when:

• Complex commission rules
• Multiple attribution models
• International payouts
• Channel partners + influencers + affiliates

It's more powerful but also more expensive and complex than PartnerStack. www.rewardful.com

3. Everflow

Strong if affiliates are only one acquisition channel and you're also running paid media.

Advantages:

• Custom conversion events
• Flexible payout rules
• Excellent reporting

Less focused on B2B SaaS partner ecosystems than PartnerStack.

4. FirstPromoter

Great if your contracts originate in Stripe.

Typical commission examples:

• 20% of first invoice
• 10% recurring
• Tiered commissions
• Renewal tracking

Once sales become CRM-driven instead of checkout-driven, you'll likely outgrow it. www.reddit.com

5. Rewardful

Excellent for Stripe-based SaaS with recurring billing.

Supports:

• One-off commissions
• Recurring commissions
• Renewal tracking
• Refund reversals

It's optimized for self-serve billing rather than enterprise CRM workflows. referralful.com

Can they pay based on contract value?

Yes. Most enterprise-oriented systems allow rules such as:

• 10% of signed contract value
• 15% of first-year ARR
• Flat $2,000 bounty
• 10% of first invoice plus 5% on renewals
• Different percentages by partner tier
• Minimum deal size requirements
• Higher commission above certain ACV thresholds

The commission is generally triggered by a CRM event (Closed Won, invoice paid, etc.) rather than simply a website conversion.

If you're selling annual enterprise contracts

I'd narrow it to:

1. PartnerStack — best balance of enterprise features and SaaS focus.
2. Impact — best for very large, sophisticated partner ecosystems.
3. Everflow — best if affiliate marketing is part of a broader performance marketing stack.
4. FirstPromoter — best for smaller SaaS companies using Stripe.

One additional consideration: if your average contract value is above roughly $20k and your sales cycle runs through Salesforce, I'd prioritize platforms that integrate deeply with your CRM rather than those built primarily around checkout events. That makes it much easier to calculate commissions from the actual signed contract value, handle multi-month sales cycles, and pay only after invoices are collected.

For an enterprise SaaS with annual contracts, the key requirements are usually more specialized than standard e-commerce affiliate software. You'll typically want support for:

• Percentage or fixed commissions based on contract value (ACV/ARR)
• One-time commissions (e.g. 15% of first-year contract)
• Recurring commissions (e.g. 10% of renewals for 2 years or lifetime)
• Manual approval before payouts (common for enterprise sales)
• CRM integrations (Salesforce, HubSpot)
• Custom attribution windows
• Support for long sales cycles (3–12+ months)
• Stripe or manual deal imports

Here are the strongest options:

Best for enterprise SaaS

PartnerStack

• Built for enterprise and mid-market SaaS.
• Supports affiliate, referral, reseller, and channel partners.
• Commission rules can be based on:
  • contract value
  • first payment
  • recurring revenue
  • renewals
  • custom events
• Strong Salesforce and HubSpot integrations.
• Handles long enterprise sales cycles well.

This is probably the closest match if your average contract value is above roughly $10k.

Best if you bill through Stripe

Rewardful

• Extremely easy to implement.
• Supports:
  • one-off commissions
  • recurring commissions
  • lifetime referrals
• Commissions can be percentage or flat amount.
• Tracks subscription renewals automatically.

Less suited if your enterprise sales happen mostly through CRM opportunities rather than Stripe checkout.

Best if commissions depend on closed deals

If sales are negotiated by account executives rather than self-serve:

• Impact.com
• Everflow
• PartnerStack

These let you approve commissions only after:

• contract signed
• payment received
• implementation completed
• trial converted

This is much closer to how enterprise SaaS partnerships usually operate.

Example commission structures

All of these platforms can generally support rules like:

My shortlist

If I were evaluating today:

1. PartnerStack — best overall for B2B enterprise SaaS partner programs.
2. Impact.com — best for large, sophisticated partnership ecosystems.
3. Everflow — best if you want highly customizable attribution and payout rules.
4. Rewardful — best for SaaS that bills primarily through Stripe.
5. FirstPromoter — strong value for growing SaaS companies.

If your sales process runs through Salesforce or HubSpot with manually negotiated annual contracts, I'd lean toward PartnerStack, Impact.com, or Everflow over simpler affiliate tools, because they handle CRM-driven workflows and complex commission logic much more naturally.

For an enterprise vertical SaaS with annual contracts, negotiated pricing, and sales-assisted deals, you typically want more than a basic affiliate platform. Specifically, you need:

• Commissions based on closed contract value (ACV or ARR) rather than fixed subscription tiers.
• Support for both one-time bounties (e.g. 10% of first-year ACV) and recurring commissions (e.g. 5% on renewals).
• CRM integration (HubSpot/Salesforce) so commissions are triggered when a deal closes rather than when someone clicks a checkout link.
• Ability to manually adjust commission amounts for custom enterprise pricing.

Here's how the leading options compare:

Best choices

1. PartnerStack

Probably the strongest fit.

Pros:

• Supports enterprise affiliate and referral programs
• Commission can be a percentage of contract value
• Handles recurring renewal commissions
• Supports manual approval before payouts
• HubSpot and Salesforce integrations
• Also gives access to a marketplace of B2B partners

Well suited for:

• $5k–100k+ ACV deals
• Annual contracts
• Agencies, consultants, implementation partners

2. Impact.com

Best if partnerships are becoming a major acquisition channel.

Supports:

• One-time referral bonuses
• Revenue share
• Renewal commissions
• Multi-touch attribution
