For a B2B SaaS selling annual plans, I’d shortlist FirstPromoter, PartnerStack, and Rewardful. The key distinction is whether by “lead-based” you mean paying for qualified leads/demos rather than only paying when a lead becomes a customer.

The important distinction

If you want to pay an affiliate for a qualified lead, e.g.:

$50 per qualified demo → $500 when that company signs an annual contract → 10% on renewal

I'd lean toward PartnerStack. It explicitly supports event-based commissions for milestones such as demo completions and contract signings, and its CRM integration can follow partner-sourced leads through the sales cycle. PartnerStack

If you primarily want affiliate → customer attribution with increasingly higher commission rates, FirstPromoter is particularly relevant. It supports tiered rates that automatically increase when affiliates cross volume thresholds, and can tie commissions to actual billing events rather than merely signups. FirstPromoter FirstPromoter

For example, you could structure:

• 1–5 annual customers: 15%
• 6–15: 20%
• 16+: 25%
• Separate $100 qualified-demo bounty
• Commission paid on first annual invoice
• Optional recurring commission on renewals

FirstPromoter explicitly supports tiered commission models and recurring subscription commissions. FirstPromoter

My practical shortlist

FirstPromoter → if you're primarily building an affiliate/referral program around your SaaS and want lots of control over commission rules.

PartnerStack → if “lead-based” really means MQL/demo → opportunity → closed-won, and you want CRM-driven partner attribution. Its positioning is specifically B2B, with full-funnel tracking and event-based commissions. PartnerStack

Rewardful → if you're on Stripe and want something relatively lightweight rather than a full partner-management system. rewardful.com

If you tell me (1) Stripe/Chargebee/etc., (2) your typical annual contract value, and (3) whether “lead” means demo booked, qualified opportunity, or closed customer, I can narrow this to the most appropriate 2–3 and show how I'd configure the commission model.

For a B2B SaaS with annual plans, I’d focus on platforms that can do two things cleanly:

1. Attribute the lead/signup before purchase, including longer sales cycles.
2. Apply commission rules based on volume or revenue tiers, rather than just “20% of every sale.”

Based on current product capabilities, these are the strongest fits:

The two I'd investigate first

FirstPromoter is particularly relevant if you want straightforward commission rules. Its current product supports percentage, flat-fee, lifetime and tiered commission models, with rates increasing when affiliates hit volume thresholds. It also connects commission events to actual subscription billing events. FirstPromoter FirstPromoter

PartnerStack is more interesting if “lead-based” means something like:

Affiliate gets $X for a qualified demo → $Y when the opportunity is created → $Z when the annual contract closes → recurring commission on renewal.

PartnerStack explicitly supports event-based commissions for milestones such as demo completions and contract signings, plus recurring commissions tied to subscriptions, renewals and expansion revenue. PartnerStack

That distinction matters for B2B SaaS: a traditional affiliate tracker is often optimized around click → signup → purchase, whereas a sales-assisted B2B motion may need lead → MQL → SQL → opportunity → closed-won → renewal.

My practical shortlist

• Sales-assisted / enterprise B2B SaaS: PartnerStack
• PLG or relatively simple annual SaaS sales: FirstPromoter
• Stripe + relatively simple affiliate program: Rewardful
• Early-stage SaaS wanting a lightweight system: Tolt
• Large, complex partner ecosystem: impact.com

One thing I'd verify in demos: whether “tiered commissions” means tiers based on affiliate performance, or genuinely different commission amounts for different funnel events. Those are quite different capabilities.

If you tell me your intended rules (e.g. $100 per qualified lead + 20% first-year ARR + 25% above $50k referred ARR), I can map that exact commission structure against these platforms.

Affiliate gets $X for a qualified demo → $Y when the opportunity is created → $Z when the annual contract closes → recurring commission on renewal.

PartnerStack explicitly supports event-based commissions for milestones such as demo completions and contract signings, plus recurring commissions tied to subscriptions, renewals and expansion revenue. partnerstack.com

That distinction matters for B2B SaaS: a traditional affiliate tracker is often optimized around click → signup → purchase, whereas a sales-assisted B2B motion may need lead → MQL → SQL → opportunity → closed-won → renewal.

My practical shortlist

For a B2B SaaS with annual plans, especially if you want both tiered commissions and lead-based tracking, I’d shortlist these:

My pick: PartnerStack

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

It supports event-based commissions, so you can pay on things like demo completion, qualified lead, opportunity, contract signing, or revenue. It also supports commission tiers and recurring commissions tied to subscriptions, renewals, and expansion. PartnerStack

That makes it particularly useful if your funnel is:

Affiliate → lead → qualified opportunity → annual contract → renewal

rather than simply:

Affiliate → Stripe checkout → commission

When I'd choose FirstPromoter instead

FirstPromoter is compelling if you're primarily running an affiliate/referral program around your billing system.

It supports tiered commission rates, recurring/lifetime commissions, and can trigger commissions based on actual billing events. It integrates with Stripe, Paddle, Chargebee, Recurly and Braintree. FirstPromoter FirstPromoter

It also has multi-level commissions if you want affiliates recruiting other affiliates. FirstPromoter

The distinction I'd make is:

• Sales-led B2B SaaS + leads/deals + partner ecosystem → PartnerStack
• Product-led SaaS + affiliates + subscription billing → FirstPromoter
• Large/complex enterprise partner ecosystem → impact.com

partnerstack.com
firstpromoter.com
impact.com

If you tell me (1) your CRM, (2) billing system, and (3) exactly how you want the tiers to work (e.g. 10% under $50k referred ARR, 15% above $50k), I can narrow this down to the best 1–2 platforms.

That makes it particularly useful if your funnel is:

Affiliate → lead → qualified opportunity → annual contract → renewal

rather than simply:

Affiliate → Stripe checkout → commission

When I'd choose FirstPromoter instead

FirstPromoter is compelling if you're primarily running an affiliate/referral program around your billing system.

It supports tiered commission rates, recurring/lifetime commissions, and can trigger commissions based on actual billing events. It integrates with Stripe, Paddle, Chargebee, Recurly and Braintree.

For a B2B SaaS selling annual plans, I’d shortlist FirstPromoter and PartnerStack, with FirstPromoter probably the best fit if you mainly need affiliate management rather than a full partner ecosystem.

My pick: FirstPromoter

FirstPromoter explicitly supports tiered commission rates, including automatically moving affiliates to higher rates when they cross thresholds based on customers referred, active customers, or revenue. It also supports commissions triggered by actual billing events rather than merely signups. FirstPromoter FirstPromoter

For an annual SaaS model, that's particularly useful if your structure looks something like:

• 10% commission for 1–10 customers
• 15% for 11–25
• 20% for 26+
• Commission paid on the annual subscription
• Higher rate based on revenue/customer volume
• Optional recurring commission on renewals

It also supports Stripe, Paddle, Chargebee, Recurly and Braintree, plus API/postback tracking. FirstPromoter

When I'd choose PartnerStack instead

If by "lead-based tracking" you mean "pay a partner for generating a qualified lead/demo/opportunity, then potentially another commission when that lead becomes a customer," I'd lean toward PartnerStack.

PartnerStack supports event-based commission models and explicitly gives examples such as rewarding affiliates for demo completions or contract signings. It also supports full-funnel tracking across clicks, conversions and revenue, plus recurring commissions for subscriptions, renewals and expansion. PartnerStack

The tradeoff is that PartnerStack is more of an enterprise B2B partner ecosystem/PRM than a lightweight affiliate tool. Current market comparisons put it substantially above the ~$50–150/month SaaS affiliate tools in pricing. Affitor

Bottom line

Choose FirstPromoter if your model is primarily:

Affiliate → lead/signup → annual subscription → commission

Choose PartnerStack if it's:

Partner → lead/demo → opportunity → closed-won annual contract → recurring/expansion commissions

One interesting detail: FirstPromoter also now supports multi-tier/multi-level rewards, so if by "tiered commissions" you mean affiliate A gets 10%, then 15% after hitting a revenue threshold, rather than affiliate A recruits affiliate B and gets an override, it handles both concepts. FirstPromoter

If you tell me your commission rules + CRM/billing stack (e.g. HubSpot + Stripe), I can narrow this down to the best 2–3 platforms and show exactly how I'd implement the tracking.

For a B2B SaaS selling annual plans, I’d shortlist FirstPromoter and PartnerStack. The better choice depends on whether “lead-based tracking” means tracking leads through your sales funnel or simply crediting an affiliate for a signup/demo.

My pick: FirstPromoter

firstpromoter.com is probably the best fit if you want a relatively straightforward affiliate program with sophisticated commission rules.

• Tiered commissions: yes — commission rates can increase based on customers referred, active customers, or revenue. FirstPromoter FirstPromoter
• Annual/recurring SaaS revenue: yes — commissions can be tied to billing events, including recurring charges, renewals, upgrades, downgrades and cancellations. FirstPromoter FirstPromoter
• Lead attribution: supports links, coupons, direct URL tracking, and postback/server-side tracking. FirstPromoter
• CRM/sales-funnel leads: this is the important caveat. It's primarily optimized around subscription/billing events rather than a full partner CRM/deal-registration workflow.

If you mean "pay affiliates for qualified leads"

Then PartnerStack is stronger.

partnerstack.com explicitly supports event-based commissions for milestones such as demo completions and contract signings, as well as CRM-connected tracking of partner-sourced leads through the sales cycle. It also supports tiers and recurring commissions on subscriptions, renewals and expansion revenue. PartnerStack

That makes it particularly attractive if your funnel looks like:

Affiliate → lead/demo → qualified opportunity → annual contract → renewal/expansion

rather than:

Affiliate → self-serve signup → Stripe payment

Quick comparison

Bottom line: If you're a SaaS company where affiliates primarily drive annual subscriptions directly, I'd start with FirstPromoter. If you're selling through a sales-assisted B2B funnel and need to compensate partners for things like MQL → SQL → demo → opportunity → closed-won, I'd choose PartnerStack.

If you tell me your average ACV, sales cycle, CRM (e.g. HubSpot/Salesforce), and exactly what event you want to pay the commission on, I can narrow it down to 2–3 platforms and show how I'd structure the tiers.

For a B2B SaaS selling annual contracts, I’d narrow it to FirstPromoter vs. PartnerStack, with the choice depending on what you mean by “lead-based tracking.”

My pick: PartnerStack if leads are central

If your funnel is something like:

Affiliate → lead → demo → qualified opportunity → annual contract → renewal

then PartnerStack is probably the stronger fit. Its affiliate product explicitly supports event-based triggers such as demo completions and contract signings, while also supporting recurring commissions tied to subscriptions, renewals, and expansion revenue. PartnerStack

That makes it much more suitable than a basic “affiliate link → Stripe checkout” system when your affiliates are actually generating sales leads that your sales team closes later.

FirstPromoter is the better value if billing is the center

firstpromoter.com is particularly attractive if you want sophisticated commission rules without going all the way to an enterprise PRM.

It supports:

• Tiered commission rates that increase when affiliates hit volume thresholds
• One-time and recurring commissions
• Multiple billing triggers
• API/postback tracking
• Coupon and link attribution
• Stripe, Paddle, Chargebee, Recurly and Braintree
• Multi-tier affiliate programs FirstPromoter FirstPromoter

One important distinction: “tiered commissions” can mean two different things. FirstPromoter supports both higher commission rates as an individual affiliate hits thresholds and multi-level/sub-affiliate commissions. FirstPromoter

What I'd choose for your model

If you're selling $5k–$50k+ annual contracts through demos/sales calls, I'd rank them:

1. PartnerStack — best if affiliates/partners generate leads that sales closes.
2. FirstPromoter — best if you want flexible commission logic and strong billing integration at a lower level of complexity.
3. Rewardful — great if virtually everything happens through Stripe checkout, but less compelling for a lead → opportunity → closed-won B2B funnel.

The key question I'd use to make the decision is: Do you need to attribute an affiliate to a lead at the top of the funnel and then pay commission when that lead becomes an annual customer weeks/months later? If yes, I'd lean PartnerStack. PartnerStack

If you tell me your CRM (HubSpot/Salesforce/etc.), billing system (Stripe/Chargebee/etc.), ACV, and commission structure, I can give you a much more definitive recommendation and map out exactly how I'd implement the tracking.

FirstPromoter is the better value if billing is the center

For a B2B SaaS selling annual plans, I’d shortlist PartnerStack and FirstPromoter. The better choice depends on what you mean by “lead-based tracking.”

My pick: PartnerStack

If your affiliates/partners can generate a lead first and revenue later, PartnerStack is the strongest match. It explicitly supports lead and deal registration, CRM-connected tracking, event-based commissions, recurring commissions, and partner tiers. It can also reward specific milestones such as demo completions or contract signings, rather than requiring an immediate purchase. PartnerStack PartnerStack

That makes it particularly suitable if your funnel looks like:

Partner referral → lead → qualified opportunity → closed annual contract → renewal/expansion

You can build commission rules around those events rather than treating everything as a simple affiliate sale.

When I'd choose FirstPromoter instead

If your annual plans are self-serve through Stripe/Paddle/Chargebee and by “lead-based” you really mean track the referral from signup through conversion, FirstPromoter is probably the better value.

It supports tiered commissions, recurring commissions, and commission structures based on plans/products. It also supports multiple tracking/attribution methods. FirstPromoter FirstPromoter

So:

• Sales-led B2B SaaS + leads/deals → PartnerStack
• PLG/self-serve SaaS + referred signups → FirstPromoter
• Simple Stripe affiliate program → Rewardful
• Large enterprise/multi-channel partnership ecosystem → impact.com

One important distinction: “tiered commissions” can mean two different things. If you mean “an affiliate earns 20% until they generate $50k, then 25% above that”, FirstPromoter explicitly supports volume-threshold tiering. If you mean “partner gets paid for recruiting sub-affiliates”, FirstPromoter also supports multi-level commissions. FirstPromoter FirstPromoter

If you tell me your average annual contract value, sales cycle, CRM (Salesforce/HubSpot/etc.), and whether leads are paid before or only after closed-won, I can narrow this to the best 2–3 platforms and compare their commission models.

Partner referral → lead → qualified opportunity → closed annual contract → renewal/expansion

You can build commission rules around those events rather than treating everything as a simple affiliate sale.

When I'd choose FirstPromoter instead

If your annual plans are self-serve through Stripe/Paddle/Chargebee and by “lead-based” you really mean track the referral from signup through conversion, FirstPromoter is probably the better value.

It supports tiered commissions, recurring commissions, and commission structures based on plans/products. It also supports multiple tracking/attribution methods.

So:

For a B2B SaaS with annual plans, tiered commissions, and lead-based tracking, I’d shortlist:

• Rewardful — strong SaaS-focused option; Stripe-native, easy affiliate setup, recurring/annual subscription attribution, and commission structures.
• FirstPromoter — particularly good for SaaS referral/affiliate programs; supports lead tracking and flexible commission rules.
• PartnerStack — best if you’re building a more sophisticated B2B partner ecosystem, with tiered commissions, lead/deal registration, and partner management.
• impact.com — powerful enterprise option with sophisticated tracking and commission structures, but more complex to implement.

My pick: If you mainly need affiliates driving annual SaaS subscriptions, start with Rewardful or FirstPromoter. If you also need lead → opportunity → closed-won tracking and multiple partner tiers, PartnerStack is the stronger fit.

If you tell me your approximate ARR/ACV, CRM (e.g. HubSpot/Salesforce), and whether commissions are paid on leads, meetings, or closed deals, I can narrow it to the best 2–3 platforms.

For a B2B SaaS selling annual plans, I’d shortlist PartnerStack and FirstPromoter first. The better choice depends on what you mean by “lead-based.”

My pick: PartnerStack

If your affiliates/partners are generating leads that enter a sales cycle—e.g. lead → demo → opportunity → closed annual contract—PartnerStack is the strongest fit. It explicitly supports event-based commissions, including milestones such as demo completions and contract signings, plus CRM-connected tracking for partner-sourced leads. It also supports recurring commissions on renewals and expansion revenue. PartnerStack

partnerstack.com

For example, you could structure something like:

• $25 per qualified lead
• $100 when the lead completes a demo
• 10% of the first annual contract
• 5% on renewals
• Higher commission rate once a partner exceeds $100k in sourced ARR

That is much closer to a B2B partner program than a traditional ecommerce-style affiliate program.

When I'd choose FirstPromoter instead

If by “lead-based” you mean something like affiliate → signup/trial → paid annual customer, rather than managing a Salesforce-style pipeline, FirstPromoter is probably the better value/simple implementation.

It supports percentage, flat, one-time, lifetime, and tiered commission rates, with tiers increasing as affiliates hit volume thresholds. It also handles subscription billing events, upgrades, cancellations and renewals. FirstPromoter FirstPromoter

firstpromoter.com

Bottom line:

• Sales-led B2B SaaS + qualified leads/opportunities → PartnerStack
• Self-serve/PLG SaaS + affiliate-generated customers → FirstPromoter
• Stripe + simple affiliate program → Rewardful

If you tell me your ACV, sales cycle, CRM (Salesforce/HubSpot/etc.), billing system, and exactly what you want the commission tiers to be, I can narrow this to one platform and map out the commission/tracking setup.

It supports percentage, flat, one-time, lifetime, and tiered commission rates, with tiers increasing as affiliates hit volume thresholds. It also handles subscription billing events, upgrades, cancellations and renewals. firstpromoter.com firstpromoter.com

For a B2B SaaS selling annual plans, you’ll usually want more than a basic affiliate link tracker. The key requirements are:

• Tiered commissions (e.g., 20% → 25% → 30% after revenue thresholds)
• Lead-based attribution (track signup → qualified lead → opportunity → closed-won)
• Recurring/annual revenue attribution
• CRM + billing integrations
• Partner portals and payout automation

The strongest fits:

My shortlist by scenario

• You have sales-assisted SaaS (demo → SDR → AE → annual contract):

Pick PartnerStack or Everflow. Lead lifecycle tracking matters more than just purchase attribution. PartnerStack Everflow

• You have self-serve SaaS (Stripe checkout, annual subscriptions):

Pick Rewardful or FirstPromoter. They’re faster to launch and naturally handle recurring revenue commissions. Rewardful FirstPromoter

• You want a multi-tier partner channel (affiliate → agency → reseller):

Lean PartnerStack or Everflow. PartnerStack Everflow

A common B2B SaaS commission model these platforms can support is:

• Tier 1: 20% of first-year ARR for partners generating < $50k ARR
• Tier 2: 25% after $50k ARR
• Tier 3: 30% after $250k ARR
• Bonus: $100–$500 for sales-qualified opportunities

If you tell me your ACV (e.g., $1k vs $25k+), sales motion (PLG vs demo-led), CRM (HubSpot/Salesforce), and billing stack (Stripe/Paddle/etc.), I can narrow this to the best 2–3 options.

For a B2B SaaS with annual plans, where you specifically need tiered commissions + lead-based tracking, I’d shortlist these:

1. PartnerStack — best fit if "lead" means pipeline

PartnerStack is probably my first choice if your affiliates/partners are generating leads that may take weeks or months to become annual contracts.

It supports commissions triggered by events such as sign-ups, demo completions, sales and contract signings, and can track partner-sourced leads through the sales cycle with CRM integration. It also supports commission structures by partner group, tier, deal stage, etc. PartnerStack PartnerStack

That makes it particularly suitable for something like:

• Lead submitted → $25
• Qualified opportunity → $100
• Annual contract closed → 15%
• $50k+ annual revenue → 20%
• Renewal → 10% recurring

2. FirstPromoter — best if you want simpler + SaaS-native

FirstPromoter is surprisingly strong for this exact use case.

It can track leads/sign-ups separately from sales, and its API lets you associate the lead with the referring affiliate before the eventual purchase. FirstPromoter Docs

It also supports performance-based tiers, where an affiliate's commission rate automatically increases based on customers, active customers, or revenue generated. FirstPromoter

For example:

1–10 customers → 15%
11–25 → 20%
26+ → 25%

It also supports multi-tier/sub-affiliate commissions if by "tiered" you mean Affiliate A recruits Affiliate B and receives an override. FirstPromoter

3. Rewardful — probably not my choice for your requirements

Rewardful is very good if you're essentially doing Stripe-based affiliate → customer → recurring commission. It automatically handles recurring charges, upgrades, downgrades and cancellations. Rewardful Help Center Rewardful

But if your definition of lead-based tracking is affiliate → lead → MQL → SQL → opportunity → annual contract, I'd choose PartnerStack instead.

My recommendation

If you're selling $5k–$100k+ annual contracts through partners: PartnerStack.

If you're selling lower/mid-ticket annual SaaS subscriptions and want a straightforward affiliate system: FirstPromoter.

The key question is what you mean by "lead-based." If you mean "pay the affiliate for submitting a lead before a sale happens," both PartnerStack and FirstPromoter can accommodate that. If you mean "track an affiliate's lead through our CRM all the way to a closed-won annual contract," PartnerStack is the much stronger fit. PartnerStack PartnerStack

For a B2B SaaS with annual plans, I’d narrow it to PartnerStack vs. FirstPromoter, depending on how sophisticated your partner motion is.

My pick: PartnerStack

If by lead-based tracking you mean something like:

Affiliate refers a company → lead enters Salesforce/HubSpot → opportunity is created → deal closes → affiliate gets X% → higher-performing affiliates move to a higher commission tier

then PartnerStack is probably the strongest fit. It explicitly supports partner-sourced leads, CRM syncing, deal registration, event-based commissions, and recurring commissions. PartnerStack PartnerStack

It also lets you structure incentives around milestones such as demo completions or contract signings, rather than requiring the commission event to be a direct online purchase. PartnerStack

The tradeoff is cost and complexity: PartnerStack is much more of a B2B partner/PRM platform than a lightweight affiliate tracker. Its current pricing is sales-led and varies by program requirements. PartnerStack

FirstPromoter is the better value if you're PLG

If your annual SaaS plan is purchased directly online—e.g. affiliate → signup → Stripe/Chargebee payment—FirstPromoter is very compelling. It supports percentage, flat, lifetime recurring, and tiered rates based on performance levels, with billing-event tracking for renewals, upgrades, downgrades and cancellations. FirstPromoter FirstPromoter

It also supports multi-level affiliate commissions, although that's different from simply having performance tiers for an individual affiliate. FirstPromoter

The key distinction

I'd choose:

• Sales-led / $10k+ ACV / leads → opportunities → closed-won: PartnerStack
• PLG / self-serve annual subscriptions / Stripe or Chargebee: FirstPromoter
• Enterprise affiliate network with highly customized tracking: TUNE
• Simple Stripe referral program: Rewardful

If you tell me your ACV, CRM (Salesforce/HubSpot/etc.), billing system, and what you mean by “tiered” (e.g. 10% for 1–10 sales, 15% for 11–25), I can give you a much more definitive recommendation.

If by lead-based tracking you mean something like:

Affiliate refers a company → lead enters Salesforce/HubSpot → opportunity is created → deal closes → affiliate gets X% → higher-performing affiliates move to a higher commission tier

then PartnerStack is probably the strongest fit. It explicitly supports partner-sourced leads, CRM syncing, deal registration, event-based commissions, and recurring commissions. PartnerStack PartnerStack

It also lets you structure incentives around milestones such as demo completions or contract signings, rather than requiring the commission event to be a direct online purchase. PartnerStack

The tradeoff is cost and complexity: PartnerStack is much more of a B2B partner/PRM platform than a lightweight affiliate tracker. Its current pricing is sales-led and varies by program requirements. PartnerStack

FirstPromoter is the better value if you're PLG

If your annual SaaS plan is purchased directly online—e.g. affiliate → signup → Stripe/Chargebee payment—FirstPromoter is very compelling. It supports percentage, flat, lifetime recurring, and tiered rates based on performance levels, with billing-event tracking for renewals, upgrades, downgrades and cancellations.

It also supports multi-level affiliate commissions, although that's different from simply having performance tiers for an individual affiliate.

For a B2B SaaS selling annual plans, I’d shortlist these three:

My pick: FirstPromoter

For your specific model, FirstPromoter is probably the sweet spot. It supports tier rewards, recurring commissions, and multiple billing integrations, and its tier system can pay an override when an affiliate recruits a sub-affiliate who generates a customer. FirstPromoter

That's particularly useful if your structure is something like:

• Affiliate generates a qualified lead → $X
• Lead books a demo → $Y
• Lead becomes an annual customer → 20% commission
• High-performing affiliates move to 25% / 30%
• Affiliate who recruited another affiliate receives a 5% override

If by "lead-based tracking" you specifically mean attributing a lead before they ever become a paying customer—e.g. webinar signup → demo → opportunity → closed-won—I'd lean toward Everflow or PartnerStack rather than a lightweight Stripe-first affiliate tool. PartnerStack explicitly supports event-based triggers for things like demo completions and contract signings, as well as full-funnel tracking. PartnerStack

One important distinction: if "tiered commissions" means commission rates based on affiliate performance (20% up to $50k, 25% above $50k), that's different from multi-tier/sub-affiliate commissions (affiliate A recruits affiliate B and gets an override). FirstPromoter supports the latter particularly well. FirstPromoter

If you tell me your CRM + billing stack (e.g. HubSpot + Stripe) and the exact commission tiers you want, I can narrow this down to the best 2–3 options and show how I'd implement the tracking.

For a B2B SaaS with annual plans, I’d shortlist FirstPromoter and PartnerStack, with the right choice depending on what you mean by “lead-based.”

My pick for your use case

If “lead-based” means an affiliate gets paid for qualified leads, demos, opportunities, or closed annual contracts—not just when someone immediately purchases—I'd choose PartnerStack.

It explicitly supports event-based commissions such as demo completions and contract signings, CRM-connected lead progression, deal registration, and recurring commissions for subscriptions/renewals/expansion. PartnerStack PartnerStack

That makes it particularly well suited to the typical B2B SaaS funnel:

Affiliate → lead → qualified opportunity → annual contract → renewal/expansion

You can then build commission rules around those milestones rather than forcing everything into “affiliate clicks → checkout.” PartnerStack is also considerably more of a partner-management platform than a basic affiliate tracker. PartnerStack PartnerStack

When I'd pick FirstPromoter instead

If your annual plans are mostly self-serve/Stripe purchases, FirstPromoter is probably the better value and simpler implementation. It supports percentage, flat, lifetime and tiered commissions, with rates increasing automatically based on affiliate volume, and commissions can be tied to actual billing events rather than merely signups. FirstPromoter

It also supports up to three levels of multi-tier commissions, if by “tiered” you mean affiliate A recruits affiliate B and earns an override. FirstPromoter FirstPromoter

Bottom line:

• Sales-assisted B2B + leads/deals + annual contracts → PartnerStack
• Self-serve SaaS + Stripe + tiered affiliate rates → FirstPromoter
• Highly customized/enterprise affiliate infrastructure → TUNE

If you tell me your average ACV, sales cycle, CRM (HubSpot/Salesforce/etc.), and whether “tiered” means volume-based rates or multi-level affiliates, I can narrow it to one platform.

If “lead-based” means an affiliate gets paid for qualified leads, demos, opportunities, or closed annual contracts—not just when someone immediately purchases—I'd choose PartnerStack.

It explicitly supports event-based commissions such as demo completions and contract signings, CRM-connected lead progression, deal registration, and recurring commissions for subscriptions/renewals/expansion. PartnerStack PartnerStack

That makes it particularly well suited to the typical B2B SaaS funnel:

Affiliate → lead → qualified opportunity → annual contract → renewal/expansion

You can then build commission rules around those milestones rather than forcing everything into “affiliate clicks → checkout.” PartnerStack is also considerably more of a partner-management platform than a basic affiliate tracker. PartnerStack PartnerStack

When I'd pick FirstPromoter instead

If your annual plans are mostly self-serve/Stripe purchases, FirstPromoter is probably the better value and simpler implementation. It supports percentage, flat, lifetime and tiered commissions, with rates increasing automatically based on affiliate volume, and commissions can be tied to actual billing events rather than merely signups.

It also supports up to three levels of multi-tier commissions, if by “tiered” you mean affiliate A recruits affiliate B and earns an override.

Bottom line:

For a B2B SaaS with annual plans, I’d shortlist FirstPromoter and PartnerStack, with the choice depending on what you mean by “lead-based.”

My pick: FirstPromoter if you're primarily affiliate-led

FirstPromoter is particularly well aligned with subscription SaaS. It can automatically track recurring and one-time charges, cancellations and refunds, and supports commission rates that increase based on revenue, customers, or active customers. It also supports up to three levels of affiliate commissions. FirstPromoter FirstPromoter FirstPromoter

For example, you could implement:

• 10% commission for partners generating $0–$10k
• 15% at $10k–$50k
• 20% above $50k
• Commission only when the referred lead becomes a paying customer
• Different commission rules for annual vs. monthly plans
• Recurring commission for a defined period, e.g. first 12 months

It also supports plan-specific rewards, which is useful if your annual Pro and Enterprise plans need different payouts. FirstPromoter FirstPromoter

When I'd choose PartnerStack instead

If by lead-based tracking you mean something like:

“Partner gets $X when a referred prospect books a demo, another amount when they become an opportunity, and 20% when the deal closes.”

Then PartnerStack is probably the stronger choice. Its commission engine supports event-based triggers such as signups and sales, while its B2B SaaS offering explicitly supports milestones like demo completions and contract signings, plus recurring commissions. PartnerStack PartnerStack

So my rule of thumb is:

PLG / self-serve annual SaaS → FirstPromoter.
Sales-led B2B SaaS with MQL → demo → opportunity → closed-won → PartnerStack.

If you tell me your annual contract value (ACV), sales cycle, CRM (HubSpot/Salesforce/etc.), and whether affiliates are paid on leads or only closed revenue, I can narrow it down to the best 2–3 platforms and compare pricing.

For a B2B SaaS selling annual plans, I’d shortlist FirstPromoter and PartnerStack, with the choice depending on what you mean by “lead-based.”

My pick: FirstPromoter

If your model is something like:

10% commission on referred annual contracts → 15% after $50k referred ARR → 20% after $100k

FirstPromoter is particularly compelling. It supports tiered rates that automatically increase when affiliates hit volume thresholds, as well as commissions based on different billing events. It also supports custom tracking and attribution. FirstPromoter FirstPromoter

firstpromoter.com

When I'd choose PartnerStack instead

If by lead-based tracking you mean:

Partner refers a lead → lead enters HubSpot/Salesforce → sales rep works it → opportunity closes months later → partner gets paid based on the eventual contract

then I'd lean PartnerStack. Its tracking is explicitly designed around partner-sourced leads and customer lifecycle stages, with CRM syncing and event-based commissions such as demo completions or contract signings. PartnerStack PartnerStack

It also has a much stronger B2B partner ecosystem/marketplace, so it's more appropriate if you're building an actual partner channel involving affiliates, agencies, consultants, resellers, etc., rather than just a referral program. PartnerStack

partnerstack.com

Bottom line:

• Affiliate → annual SaaS purchase: FirstPromoter
• Affiliate → qualified lead → sales pipeline → annual contract: PartnerStack
• Need both, with complex CRM-based attribution: PartnerStack is probably the safer long-term choice.

If you tell me your CRM (HubSpot/Salesforce/etc.), billing system (Stripe/Chargebee/etc.), and exactly when you want the commission to trigger, I can narrow this to the best 2–3 platforms and compare their pricing.

If your model is something like:

10% commission on referred annual contracts → 15% after $50k referred ARR → 20% after $100k

FirstPromoter is particularly compelling. It supports tiered rates that automatically increase when affiliates hit volume thresholds, as well as commissions based on different billing events. It also supports custom tracking and attribution. FirstPromoter FirstPromoter

firstpromoter.com

When I'd choose PartnerStack instead

If by lead-based tracking you mean:

Partner refers a lead → lead enters HubSpot/Salesforce → sales rep works it → opportunity closes months later → partner gets paid based on the eventual contract

then I'd lean PartnerStack. Its tracking is explicitly designed around partner-sourced leads and customer lifecycle stages, with CRM syncing and event-based commissions such as demo completions or contract signings. partnerstack.com partnerstack.com

It also has a much stronger B2B partner ecosystem/marketplace, so it's more appropriate if you're building an actual partner channel involving affiliates, agencies, consultants, resellers, etc., rather than just a referral program.

For a B2B SaaS with annual plans, I’d shortlist PartnerStack and FirstPromoter. The better choice depends on what you mean by “lead-based tracking.”

My pick: PartnerStack

If your funnel looks like:

Affiliate → lead/demo → qualified opportunity → closed annual contract → renewal

then PartnerStack is probably the strongest fit. It can track partner-sourced leads through the CRM, trigger commissions on events such as signups or contract signings, and supports different commission structures by partner group/tier. It also handles recurring revenue, renewals, and expansion. PartnerStack PartnerStack

It is particularly compelling if your affiliates are really referral/agency/partner relationships, rather than traditional coupon/content affiliates.

partnerstack.com

FirstPromoter is the better lightweight option

If you're primarily running an affiliate program around your annual SaaS subscriptions, FirstPromoter is worth serious consideration. It supports tiered rates that increase with affiliate performance, recurring/lifetime commissions, custom rewards, and multiple billing systems including Stripe, Paddle, Chargebee, Recurly and Braintree. FirstPromoter FirstPromoter

It also supports attribution through links, coupons and direct tracking, which is useful if affiliates generate leads through content, podcasts, outbound, etc. FirstPromoter

firstpromoter.com

The key distinction

I'd choose:

• PartnerStack → if “lead-based” means paying for qualified leads, opportunities, demos, or closed-won deals, especially with a CRM-driven sales cycle.
• FirstPromoter → if “lead-based” means affiliate attribution around SaaS signups/conversions, and you want more control without buying a full PRM.
• Rewardful → if you're mostly Stripe + straightforward affiliate referrals and don't need sophisticated lead/opportunity workflows. Rewardful

For your specific case, if you tell me your commission model (e.g. “$100 per qualified lead + 20% of first-year ARR, with 25% after 10 deals”), I can tell you which platform handles it cleanly and where each one hits limitations.

If your funnel looks like:

Affiliate → lead/demo → qualified opportunity → closed annual contract → renewal

then PartnerStack is probably the strongest fit. It can track partner-sourced leads through the CRM, trigger commissions on events such as signups or contract signings, and supports different commission structures by partner group/tier. It also handles recurring revenue, renewals, and expansion. PartnerStack PartnerStack

It is particularly compelling if your affiliates are really referral/agency/partner relationships, rather than traditional coupon/content affiliates.

It supports tiered rates that increase with affiliate performance, recurring/lifetime commissions, custom rewards, and multiple billing systems including Stripe, Paddle, Chargebee, Recurly and Braintree. firstpromoter.com firstpromoter.com

It also supports attribution through links, coupons and direct tracking, which is useful if affiliates generate leads through content, podcasts, outbound, etc.

For a B2B SaaS with annual plans, I’d shortlist FirstPromoter and PartnerStack, with the choice depending on what you mean by “lead-based tracking.”

• firstpromoter.com — best fit for most SaaS teams. It supports tiered commission rates based on affiliate performance, recurring/lifetime commissions, and tracking tied to actual billing events. It also supports event-based commission triggers and integrations with Stripe, Paddle, Chargebee, Recurly, and Braintree. FirstPromoter FirstPromoter
• partnerstack.com — better if you have a more enterprise partner program. It supports event-based commissions, including milestones such as demo completions or contract signings, plus tiers, recurring commissions, and full-funnel tracking from click → conversion → revenue. PartnerStack
• Rewardful is attractive for a simpler Stripe/Paddle setup, but I'd put it behind the two above if lead-stage commissions and sophisticated tiers are core requirements. Rewardful

For your specific model

If your intended logic is something like:

Affiliate sends lead → $X when qualified/demo booked → $Y when opportunity closes → 20% of first annual contract → higher commission rate after $50k/$100k in referred ARR

PartnerStack is the stronger fit. Its event-based model is explicitly designed around milestones beyond just a paid subscription. PartnerStack

If instead you mean:

Affiliate gets 20% of annual revenue, then 25% after 10 customers, then 30% after 25 customers

FirstPromoter is probably the better value/simple implementation. It specifically supports performance-based tiered rates and subscription billing events. FirstPromoter FirstPromoter

My pick: FirstPromoter for a typical growing B2B SaaS; PartnerStack if you have sales-led, multi-stage partner attribution and a larger partner operation.

If you tell me your CRM (HubSpot/Salesforce/etc.), billing system (Stripe/Chargebee/etc.), and exactly when you want to pay the commission, I can narrow it to the best 2–3 platforms.

For an annual-plan B2B SaaS, I’d shortlist FirstPromoter and PartnerStack, with the choice depending on what you mean by “lead-based.”

My pick: FirstPromoter

If your model is something like:

Affiliate generates a lead → lead becomes an annual customer → affiliate earns 20% → after 10 customers, 25% → after 25 customers, 30%

FirstPromoter is particularly well suited. It supports tiered rates based on performance thresholds and can track subscription billing events, including upgrades, cancellations and refunds. FirstPromoter FirstPromoter

It also supports custom/API-based tracking, so if “lead” means MQL, SQL, demo booked, opportunity created, or closed-won, rather than simply “signup,” you have more flexibility than with a basic affiliate tracker. FirstPromoter

When I'd choose PartnerStack instead

Go with PartnerStack if you're building a broader B2B partner channel rather than just an affiliate program—for example, affiliates + agencies + consultants + resellers, with CRM pipeline/deal tracking. It explicitly positions itself around B2B SaaS, full-funnel tracking, event-based commissions, and recurring commissions tied to renewals and expansion. PartnerStack PartnerStack

Bottom line:

• Affiliate-led SaaS growth + tiered commissions → FirstPromoter
• Enterprise B2B partner/channel program + CRM pipeline → PartnerStack

If you tell me your billing stack (Stripe/Chargebee/etc.), what counts as a “lead,” and your commission tiers, I can narrow it down to the best 2–3 platforms and compare the exact implementation.

If your model is something like:

Affiliate generates a lead → lead becomes an annual customer → affiliate earns 20% → after 10 customers, 25% → after 25 customers, 30%

When I'd choose PartnerStack instead

Go with PartnerStack if you're building a broader B2B partner channel rather than just an affiliate program—for example, affiliates + agencies + consultants + resellers, with CRM pipeline/deal tracking. It explicitly positions itself around B2B SaaS, full-funnel tracking, event-based commissions, and recurring commissions tied to renewals and expansion.

Bottom line:

For a B2B SaaS selling annual plans, especially if you want tiered commissions + lead-based tracking, I’d shortlist PartnerStack first.

My pick: PartnerStack

PartnerStack is specifically built around B2B SaaS and supports lead/deal registration, full-funnel tracking, event-based commissions, partner tiers, and recurring commissions. That makes it particularly well suited if an affiliate might generate a lead today but the customer doesn't purchase until weeks or months later. PartnerStack PartnerStack

For example, you could structure:

• Lead: $25–$100 qualified-lead bounty
• New annual customer: 20% of first-year ACV
• Tier 2: 25% after 10 customers
• Tier 3: 30% after 25 customers
• Renewal: 10% for year 2, if desired
• CRM status/events determine when commissions become payable

That is much closer to a B2B partner program than a traditional ecommerce affiliate program.

When I'd choose FirstPromoter instead

FirstPromoter is compelling if your sales motion is predominantly self-serve and you want something considerably simpler. It supports percentage, flat, one-time, lifetime and tiered commission models, with rates increasing as affiliates hit volume thresholds. FirstPromoter

Its multi-tier functionality can also handle partner recruitment/sub-affiliates, and it tracks recurring subscription charges, cancellations and refunds. FirstPromoter

Bottom line:

• Sales-assisted B2B SaaS, leads → opportunities → annual contracts: PartnerStack
• Self-serve SaaS, signup → annual subscription: FirstPromoter
• Simple Stripe affiliate program: Rewardful
• Large, complex enterprise partner ecosystem: impact.com

If you tell me your average ACV, sales cycle, CRM (e.g. HubSpot/Salesforce), and whether “lead” means MQL, SQL, demo, or closed-won, I can narrow this to the best 2 and compare the actual commission/attribution mechanics.

For a B2B SaaS with annual plans, I’d shortlist PartnerStack and FirstPromoter first. The right choice depends on what you mean by “lead-based.”

My pick: PartnerStack

partnerstack.com is the strongest fit if your affiliates/partners generate leads that enter a sales pipeline before an annual contract closes.

It supports:

• Tracking click → lead → conversion → revenue across the funnel.
• CRM-connected attribution so you can follow a referred lead through the sales cycle.
• Event-based commissions, such as rewarding a demo completion or contract signing.
• Recurring commissions tied to subscriptions, renewals, and expansion.
• Commission structures based on tier, partner type, region, or deal stage. PartnerStack PartnerStack

That's particularly valuable if your flow is:

Affiliate → demo/signup → qualified lead → sales opportunity → annual contract → renewal

rather than simply:

Affiliate → Stripe checkout → commission

FirstPromoter is the better lightweight option

firstpromoter.com is compelling if you're primarily running a self-serve SaaS affiliate program.

It can track a referred visitor when they become a lead, associate that lead with the eventual customer, and automatically calculate commissions from billing events. It supports Stripe, Chargebee, Paddle, Recurly and Braintree. FirstPromoter Docs FirstPromoter

It also has unusually flexible tiering: you can increase commission rates based on revenue generated, number of customers, or active customers. It supports up to three levels of parent/sub-affiliate commissions as well. FirstPromoter FirstPromoter

Where Rewardful fits

rewardful.com is attractive if you're Stripe-first and want minimal implementation overhead. It handles recurring subscription commissions and billing changes, and its current feature set includes tiered commission rates. Rewardful Help Center Rewardful

But for a true B2B sales-assisted funnel where the affiliate gets credit for a lead that closes months later, I'd favor PartnerStack.

Bottom line:

• Sales-led B2B SaaS + lead/opportunity attribution → PartnerStack
• Product-led SaaS + annual subscriptions + sophisticated affiliate tiers → FirstPromoter
• Stripe SaaS + simple affiliate program → Rewardful

If you tell me your CRM (Salesforce/HubSpot/etc.), billing system (Stripe/Chargebee/etc.), and the exact tier rule (e.g. “10% for first 10 customers, 15% thereafter”), I can narrow it down to the best platform and flag any implementation gotchas.

Affiliate → Stripe checkout → commission

FirstPromoter is the better lightweight option

firstpromoter.com is compelling if you're primarily running a self-serve SaaS affiliate program.

It can track a referred visitor when they become a lead, associate that lead with the eventual customer, and automatically calculate commissions from billing events. It supports Stripe, Chargebee, Paddle, Recurly and Braintree. docs.firstpromoter.com help.firstpromoter.com

It also has unusually flexible tiering: you can increase commission rates based on revenue generated, number of customers, or active customers. It supports up to three levels of parent/sub-affiliate commissions as well. help.firstpromoter.com help.firstpromoter.com

Where Rewardful fits

For a B2B SaaS selling annual plans, especially if you need tiered commissions + lead-based tracking, I’d shortlist these:

My pick: PartnerStack

If by lead-based you mean “pay an affiliate when they generate a qualified lead/demo/opportunity, then potentially pay more when that lead becomes a customer,” PartnerStack is probably the strongest match.

It supports event-based commission triggers, including things like demo completions and contract signings, and can connect partner-sourced leads to your CRM so you can track progression through the sales cycle. It also supports recurring commissions tied to subscriptions, renewals, and expansion revenue. PartnerStack PartnerStack

That's particularly valuable for B2B SaaS where an affiliate might generate a lead today but the $10k annual contract doesn't close for 60–120 days.

FirstPromoter is the better alternative if you're more sales/affiliate than partner-program oriented

FirstPromoter has unusually flexible commission logic: percentage, flat fee, one-time, lifetime recurring, and tiered rates based on performance thresholds. It also supports different commission structures by plan/product and tracks actual billing events rather than merely signups. FirstPromoter FirstPromoter

For example, you could do something like:

• 10% for $0–$20k referred ARR
• 15% for $20k–$50k
• 20% above $50k
• Or $100 per qualified lead + 15% when that lead becomes a customer

It also supports multi-tier/sub-affiliate arrangements if that's what you mean by "tiered." FirstPromoter

I wouldn't make Rewardful the first choice for this use case

Rewardful is excellent if you're primarily Stripe + straightforward recurring affiliate commissions. It tracks subscription invoices and handles upgrades, downgrades, cancellations, etc. Rewardful Help Center Rewardful Help Center

But if lead → opportunity → closed-won attribution and sophisticated commission tiers are core requirements, I'd favor PartnerStack or FirstPromoter.

Bottom line:

• Complex B2B sales funnel / CRM leads / partners: PartnerStack
• Flexible affiliate commissions / performance tiers / SaaS billing: FirstPromoter
• Simple Stripe subscription affiliate program: Rewardful

If you tell me whether your leads come through HubSpot/Salesforce and roughly what your ACV and sales cycle are, I can narrow this down to the best 2–3 options and compare their pricing/features.

That's particularly valuable for B2B SaaS where an affiliate might generate a lead today but the $10k annual contract doesn't close for 60–120 days.

FirstPromoter is the better alternative if you're more sales/affiliate than partner-program oriented

For a B2B SaaS with annual plans, I’d shortlist PartnerStack and FirstPromoter first. The better choice depends on what you mean by “lead-based.”

My pick: PartnerStack

If you're selling annual B2B contracts where a “lead” may sit in your CRM for weeks/months before becoming revenue, PartnerStack is the strongest match.

It can track partner-sourced leads and deals, sync activity with your CRM, and then apply payout rules once those events/conversions occur. Its commission engine supports structures based on partner type, tier, region, deal stage, milestones, and multi-step revenue share. PartnerStack PartnerStack

That's materially different from a basic affiliate tool where the primary model is:

affiliate link → signup → Stripe payment → commission

For your model, you might configure something like:

• Tier 1: 10% of first-year ARR for partners generating <$50k
• Tier 2: 15% at $50k–$150k
• Tier 3: 20% above $150k
• Lead registered → no payout
• Qualified opportunity → optional fixed bounty
• Closed-won annual contract → commission
• Renewal → separate recurring/renewal commission

PartnerStack explicitly supports commission triggers on events such as signups and sales, plus different structures for partner groups. PartnerStack

When I'd choose FirstPromoter instead

If your “leads” are essentially affiliate-driven signups that eventually subscribe, rather than sales-qualified opportunities managed by an AE, FirstPromoter is probably the more attractive/lighter solution.

It supports one-time, lifetime, percentage, flat-fee and tiered commissions, with rates automatically increasing when affiliates hit volume thresholds. It also supports multi-tier affiliate rewards. FirstPromoter FirstPromoter

Rewardful

I'd put Rewardful third for your particular use case. It's excellent if you're Stripe-based and want something quick: it tracks referrals through signup/purchase and automatically adjusts commissions for upgrades, downgrades, cancellations, trials and other billing events. Rewardful Help Center Rewardful Help Center

But for a true B2B partner motion with lead registration → opportunity → closed-won → commission, PartnerStack is the better architectural fit.

Bottom line:
PartnerStack if “lead” means CRM lead/opportunity and you need sophisticated tiered partner payouts.
FirstPromoter if “lead” means affiliate referral/signup and you want a simpler, more product-led affiliate system.
Rewardful if you're heavily Stripe-centric and prioritize simplicity.

If you tell me your CRM (Salesforce/HubSpot/etc.), billing system (Stripe/Chargebee/etc.), and the exact tier rules, I can narrow this to the best 2 and map how each would implement your commission logic.

For a B2B SaaS with annual plans, where you want both tiered commissions and lead-based tracking, I’d shortlist these:

My pick: PartnerStack

For your specific model, PartnerStack is probably the strongest fit. It explicitly supports event-based commissions, partner tiers, recurring commissions, and CRM-connected lead tracking. You can reward an affiliate for something like qualified demo → opportunity → signed annual contract, rather than requiring an immediate online purchase. partnerstack.com

That matters a lot for B2B SaaS: if someone refers a lead today but your sales team closes the $20k/year contract 60 days later, you want the attribution to survive the sales cycle.

You could structure something like:

• Tier 1: 10% of first-year ACV
• Tier 2: 15% after $50k referred ACV
• Tier 3: 20% after $150k
• Lead milestone: $100 for a qualified demo
• Conversion milestone: additional commission when the annual contract is signed
• Renewal: optional recurring commission

PartnerStack specifically supports milestones such as demo completions and contract signings, as well as CRM-synced leads and recurring/expansion revenue. partnerstack.comdocs.affitor.com

When I'd choose FirstPromoter instead

If you're primarily an affiliate program rather than a broader partner/reseller ecosystem, FirstPromoter is worth a serious look. It is more lightweight and SaaS-focused, with recurring/MRR-based commission capabilities and support for several billing systems. docs.affitor.com

Rule of thumb:

• B2B + sales-assisted + lead/deal stages → PartnerStack
• Self-serve SaaS + affiliates + simpler setup → FirstPromoter
• Highly customized attribution/event tracking → Everflow

If you tell me your ACV, sales cycle (e.g. 30/60/90 days), CRM (HubSpot/Salesforce), and billing system (Stripe/Chargebee/etc.), I can narrow this to 2–3 platforms and show you exactly how I'd implement the commission model.

For a B2B SaaS selling annual plans, you’ll generally want an affiliate platform that supports:

• Recurring or annual commissions (e.g., pay a percentage of first-year ARR or a recurring percentage)
• Tiered commission structures (affiliate levels, partner tiers, performance bonuses)
• Lead-based attribution (track MQLs, SQLs, demos booked, trials started—not just purchases)
• Long sales-cycle workflows (cookie + account-based tracking, CRM syncing, offline conversion approval)
• B2B integrations (HubSpot, Salesforce, Stripe, Chargebee, Recurly, etc.)

Platforms worth evaluating:

My shortlist for your specific model:

1. B2B SaaS with sales-assisted annual contracts ($1k+ ARR):

→ PartnerStack or Everflow
These handle partner pipelines better than traditional affiliate tools.

2. Self-serve SaaS with Stripe subscriptions:

→ Rewardful or FirstPromoter
Easier to launch and maintain.

3. Complex partner program with multiple tiers:

→ Everflow or Impact.com
Better if you need rules like:

• Tier 1 affiliates: 20% first-year commission
• Tier 2 partners: 30% after $50k sourced ARR
• Bonus payouts for qualified demos
• Different commissions by customer segment

For lead-based B2B SaaS, I’d prioritize platforms that can pass events like:

• lead created
• demo booked
• opportunity created
• closed-won ARR
• renewal

rather than relying only on checkout conversions.

A common stack for B2B SaaS is:

• PartnerStack/Everflow → partner attribution + commissions
• HubSpot/Salesforce → lead and opportunity lifecycle
• Stripe/Chargebee → revenue confirmation and payout triggers

If you share your approximate ACV (e.g., $500/year vs $20k/year) and whether sales closes deals in a CRM, the best fit narrows quite a bit.

For a B2B SaaS selling annual plans, I’d shortlist FirstPromoter and PartnerStack, with the right choice depending on what you mean by “lead-based.”

My pick: FirstPromoter

firstpromoter.com is probably the best fit if you want flexible affiliate economics without buying a full enterprise PRM.

It supports:

• Tiered commissions — affiliate rates can increase automatically when partners hit customer/revenue thresholds.
• Lead/event-based commissions — you can trigger rewards on events such as demo completions or other billing/conversion events.
• Annual/subscription billing — commissions can be tied to first payment, subsequent payments, or lifetime revenue.
• Multi-tier recruiting — if by “tiered” you mean affiliates recruiting sub-affiliates, it supports up to three levels.
• Stripe, Paddle, Chargebee, Recurly and Braintree integrations. FirstPromoter FirstPromoter

That makes it particularly attractive if your model is something like:

Partner generates a qualified lead → gets $X
Lead becomes an annual customer → gets Y%
Partner exceeds $100k in referred ARR → commission increases from 15% → 20%

PartnerStack if leads/deal registration are central

partnerstack.com is stronger if you're really running a B2B partner/channel program, rather than a conventional affiliate program.

It tracks the partner-sourced journey from lead → opportunity → customer → revenue, syncs with your CRM, supports event-based commission rules, and is designed around different partner types and partner tiers. PartnerStack PartnerStack

I'd choose PartnerStack if you're working with agencies, consultants, resellers, referral partners, etc. and need lead/deal registration + CRM integration + partner management.

Quick decision

Bottom line: If you're primarily recruiting affiliates and want tiered commissions + lead tracking + annual-plan attribution, I'd start with FirstPromoter. If “lead-based” means MQL/SQL → opportunity → closed-won and your partners are agencies/channel sellers, I'd go PartnerStack instead. FirstPromoter PartnerStack

If you tell me your CRM (HubSpot/Salesforce/etc.), billing system (Stripe/Chargebee/etc.), and what you mean by a “lead” (form fill, booked demo, SQL, closed deal), I can narrow this to the best 2–3 platforms and show exactly how I'd structure the commission rules.

For a B2B SaaS with annual plans, I’d shortlist FirstPromoter and PartnerStack, with the choice depending on whether you mean tiered commission rates or multi-level affiliates.

My pick: FirstPromoter

If your flow is something like:

Affiliate → lead/signup → annual contract → commission based on plan/revenue → higher commission after X customers

then FirstPromoter is probably the cleanest fit. It supports percentage, flat, one-time, lifetime recurring, and tiered rates that increase when affiliates hit volume thresholds. It also tracks actual billing events rather than treating a signup as the conversion. firstpromoter.com

It also supports multi-tier affiliate commissions—e.g. an affiliate recruits a sub-affiliate and receives an override on that sub-affiliate's sales. firstpromoter.com

When I'd choose PartnerStack instead

If by "lead-based tracking" you mean:

"Affiliate generates a lead → our SDR works it → opportunity → closed-won annual contract"

I'd lean PartnerStack. It explicitly supports CRM-connected tracking of partner-sourced leads through the sales cycle, event-based commissions such as demo completion or contract signing, and recurring commissions on renewals/expansion. partnerstack.com

That's a materially better model for sales-assisted B2B SaaS than a traditional affiliate platform.

Rule of thumb:

• PLG / self-serve annual SaaS: FirstPromoter
• Affiliate recruits other affiliates: FirstPromoter
• Lead → opportunity → closed-won sales motion: PartnerStack
• Large ecosystem with affiliates + resellers + strategic partners: PartnerStack / impact.com

If you tell me your CRM (HubSpot/Salesforce/etc.), billing system (Stripe/Chargebee/etc.), and what you mean by tiered (e.g. 20% for 1–10 deals, 25% for 11–25), I can narrow it down to the best 2–3 and map exactly how each would implement your commission logic.

For a B2B SaaS with annual plans, where you specifically need tiered commissions + lead-based tracking, I’d shortlist these:

Tapfiliate explicitly supports multi-tier commission structures, recurring commissions, and performance-triggered tier upgrades, and lets you track custom conversion parameters. tapfiliate.com

What I'd choose

If your funnel is:

Affiliate → qualified lead → demo → opportunity → annual contract

I'd lean PartnerStack. It's designed more like a B2B partner platform, with lead/deal registration and multiple partner types, rather than just an affiliate-link tracker. It's also considerably more expensive and generally aimed at established SaaS companies. docs.affitor.com

If your funnel is:

Affiliate → signup/trial → annual subscription

I'd lean Tapfiliate or FirstPromoter. FirstPromoter is particularly strong if you want commissions tied to subscription billing events and you're using Stripe/Paddle/Chargebee/Recurly. www.rewardful.com

One important distinction: if by "lead-based tracking" you mean pay $X when an affiliate generates a qualified lead, then another commission when that lead closes, that's materially different from ordinary affiliate conversion tracking. PartnerStack or Tapfiliate would be the first two I'd evaluate.

If you tell me your CRM (Salesforce/HubSpot/etc.), billing system, average ACV, and what the commission tiers look like, I can narrow it to 1–2 platforms and map out exactly how I'd implement the tracking.

For a B2B SaaS selling annual plans, I’d shortlist FirstPromoter and PartnerStack. The better choice depends on what you mean by “lead-based tracking.”

My pick: FirstPromoter if it's primarily an affiliate program

FirstPromoter is unusually well aligned with your requirements. It supports automatic commission tiers based on revenue, customers, or active customers, so you could do something like:

• 1–10 customers → 15%
• 11–25 → 20%
• 26+ → 25%

It can also handle recurring commissions and billing events, including annual charges. help.firstpromoter.com

It also supports plan-level rewards, which is useful if your annual plans have substantially different ACVs or you want different payouts for enterprise plans. help.firstpromoter.com

FirstPromoter

But choose PartnerStack if “lead” means MQL → SQL → closed-won

This is the important distinction.

If your affiliates/partners are sending leads that enter a sales process, rather than immediately purchasing through a checkout, I'd lean PartnerStack. It supports event-based commissions such as signups, demo completions and contract signings, and its tracking covers the partner-sourced lead through the revenue funnel. partnerstack.com

That's much closer to a model like:

Partner generates lead → lead becomes qualified → opportunity → annual contract closes → partner receives $X / Y% → higher tier after $250k sourced ARR.

PartnerStack

Where Rewardful fits

If you're Stripe-based and want something simpler, Rewardful is worth considering. It tracks referred visitors, leads and conversions and automatically adjusts commissions for upgrades, downgrades, cancellations, refunds, etc. help.rewardful.com

Rewardful

Bottom line:

• Affiliate → direct annual purchase: FirstPromoter
• Affiliate/partner → lead → sales-assisted annual contract: PartnerStack
• Stripe SaaS + simple affiliate program: Rewardful

If you tell me (1) whether leads close through Stripe or your CRM, (2) your desired tier structure, and (3) roughly how many affiliates/partners you expect, I can narrow it down to one and compare the pricing/implementation tradeoffs.

For a B2B SaaS selling annual plans, the two I'd shortlist are FirstPromoter and PartnerStack. The right choice depends on what you mean by “lead-based.”

My pick: PartnerStack if leads matter

If your funnel looks like:

Affiliate → lead → demo → opportunity → annual contract → renewal

I'd lean PartnerStack. It explicitly supports lead submission and deal registration, tracks partner-sourced leads through the sales cycle, and can connect that progression to your CRM. It also supports event-based commissions, so you can reward things like demo completion or contract signing, rather than only paying when someone clicks a link or immediately purchases. partnerstack.com

That's particularly useful if an affiliate sends you a prospect in January but you don't close the $12k annual contract until March.

FirstPromoter if the sale is mostly self-serve

I'd choose FirstPromoter if your annual SaaS plans are purchased directly through Stripe/Paddle/etc. and you primarily need:

• 20% commission on annual revenue
• higher commission tiers after $X in sales
• recurring/renewal commissions
• commission rules by billing event
• coupon + link attribution
• subscription lifecycle tracking

FirstPromoter explicitly supports tiered commission rates, including performance thresholds, and tracks renewals, upgrades, downgrades, cancellations, etc. firstpromoter.com

It also supports multi-tier affiliate structures (e.g. a promoter earning a percentage from sub-affiliates), up to three tiers. help.firstpromoter.com

So, in one sentence:

• Sales-led B2B SaaS + CRM leads/opportunities → PartnerStack
• Product-led/self-serve SaaS + annual subscriptions + flexible commission tiers → FirstPromoter

If you tell me (1) your CRM, (2) Stripe/Chargebee/etc., (3) typical annual contract value, and (4) whether affiliates get paid for leads before a deal closes, I can narrow this to the best 2–3 platforms and compare their actual commission/attribution capabilities.

For a B2B SaaS selling annual plans, I’d shortlist FirstPromoter and PartnerStack, with FirstPromoter as the likely best fit unless you need enterprise partner-management capabilities.

Why I'd pick FirstPromoter

FirstPromoter explicitly supports tiered commission rates that automatically increase when an affiliate reaches volume thresholds. It also supports one-time, recurring, flat-fee and percentage commissions. firstpromoter.commirror.fprom.co

More importantly for your model, it ties tracking to actual subscription billing events—including renewals, upgrades, downgrades, cancellations and reactivations. That matters much more for annual SaaS than simply tracking clicks → purchases. firstpromoter.commirror.fprom.co

It also supports custom event/lead-style tracking, so you can structure something like:

Affiliate generates lead → lead books demo → opportunity created → annual contract closes → affiliate receives commission

When I'd choose PartnerStack instead

If by "lead-based" you mean you want to pay partners for pipeline milestones before revenue, PartnerStack is particularly compelling. Its platform supports event-based commissions for things such as demo completions and contract signings, plus full-funnel tracking and recurring commissions for subscriptions, renewals and expansion. partnerstack.com

That's the better choice if you're building a B2B partner channel, rather than just an affiliate program.

My recommendation

If you have a relatively straightforward affiliate program: FirstPromoter.

If you have sales-assisted deals and want partners rewarded for qualified leads/opportunities/contracts: PartnerStack.

For example, if your commission rules look something like 10% on annual contract #1, 15% after $50k referred ARR, 20% after $100k, plus $X for qualified demos, I'd lean PartnerStack if those lead milestones are central; otherwise FirstPromoter gives you a much simpler implementation.

If you tell me your CRM/billing stack (e.g. HubSpot + Stripe) and the exact commission tiers you have in mind, I can narrow it down to the best platform and explain how I'd implement the attribution.

For a B2B SaaS selling annual plans, I’d shortlist PartnerStack and FirstPromoter. The better choice depends on what you mean by “lead-based.”

My pick: PartnerStack

If your sales process looks something like:

Affiliate/partner → lead → demo → opportunity → annual contract → renewal/expansion

then PartnerStack is the strongest fit. It explicitly supports event-based commissions for milestones such as demo completion and contract signing, full-funnel tracking, CRM syncing, commission tiers, and recurring commissions on subscriptions/renewals/expansion. partnerstack.com

That's materially different from simply tracking an affiliate link until someone purchases.

When I'd choose FirstPromoter instead

If by “lead-based tracking” you mean something closer to:

“Give affiliates credit for the lead/signup, then pay them when that lead becomes a paying annual customer.”

FirstPromoter is probably the better value and simpler implementation. It supports tiered commission rates and can trigger commissions based on actual billing events rather than merely a signup. It also integrates with Stripe, Paddle, Chargebee, Recurly and Braintree. firstpromoter.com

One important distinction: FirstPromoter is primarily an affiliate/revenue-tracking system, whereas PartnerStack is more of a B2B partner ecosystem/PRM platform.

Rule of thumb:

• Affiliate → signup → annual purchase: FirstPromoter
• Partner → lead → sales pipeline → contract: PartnerStack
• Partner gets $X for qualified lead + $Y when deal closes + higher % after volume thresholds: PartnerStack

If you tell me your commission structure (e.g. $100 per qualified lead + 20% of first-year ARR, with tiers at 10/25/50 deals) and whether you're on HubSpot/Salesforce + Stripe, I can narrow it to the best 2–3 options.

For a B2B SaaS selling annual plans, I’d shortlist these three:

My pick: FirstPromoter

FirstPromoter is probably the sweet spot if you're primarily running an affiliate program rather than a full partner ecosystem. It supports tiered commission rates, including rates that automatically increase when affiliates hit volume thresholds, and it tracks subscription billing events rather than treating the initial conversion as the whole relationship. firstpromoter.com

For example, you could structure:

• 20% commission for 1–5 customers
• 25% for 6–15
• 30% for 16+
• Commission calculated on the annual contract value
• Or commission triggered at a qualified lead/demo and paid when the deal closes

If "lead-based" is the key requirement: PartnerStack

PartnerStack is stronger if your funnel looks like:

affiliate → lead/demo → opportunity → closed-won annual contract → renewal

PartnerStack explicitly supports event-based commission triggers, including demo completions and contract signings, as well as full-funnel tracking and recurring commissions. firstpromoter.compartnerstack.com

That's particularly useful if your affiliates aren't sending people straight to checkout and your sales team closes the $5k–$50k+ annual contracts.

If you need sophisticated attribution: Everflow

I'd look at Everflow if you want more of an attribution/partner-tracking engine than a simple SaaS affiliate tool. It's worth considering when you need multiple conversion events, custom postbacks, CRM integration, or complex commission logic.

Bottom line:

• Self-serve SaaS + annual Stripe subscriptions → FirstPromoter
• B2B SaaS + demos/SQLs/opportunities + sales team → PartnerStack
• Complex multi-stage attribution + lots of custom events → Everflow

One important distinction: if by “lead-based tracking” you mean “pay $X when an affiliate generates a qualified lead, then another $Y/% when that lead becomes a customer,” I'd lean PartnerStack/Everflow over FirstPromoter. If you tell me your CRM + billing stack (e.g. HubSpot + Stripe) and roughly ACV, I can narrow it to the best 1–2 options.

For a B2B SaaS selling annual plans, where you specifically need tiered commissions + lead-based tracking, I’d shortlist these:

My pick: PartnerStack

If by lead-based you mean something like:

Affiliate refers prospect → prospect becomes MQL → SQL → demo → closed-won annual contract → affiliate gets paid according to the stage/value

then PartnerStack is the strongest fit. It supports event-based commissions such as demo completions and contract signings, CRM-connected tracking for partner-sourced leads, and recurring commissions tied to subscriptions, renewals, and expansion revenue. partnerstack.com

That's materially different from a typical SaaS affiliate tool that essentially says "affiliate link → Stripe purchase → commission."

FirstPromoter is worth considering

FirstPromoter is particularly attractive if your sales motion is relatively straightforward and you want something less heavyweight. It supports percentage, flat, lifetime and tiered commission models, including multi-tier parent/sub-affiliate structures. firstpromoter.com

The catch is that its core model is much more centered on billing events and referred sales. For a true B2B lead lifecycle where the CRM is the source of truth before the annual contract closes, PartnerStack is a better architectural match.

The key question

If your commission model looks like:

$X per qualified lead → $Y when opportunity created → Z% of first-year ARR when closed

I'd go PartnerStack.

If it looks more like:

30% of the annual subscription, with higher rates after an affiliate hits 10/25/50 customers

I'd lean FirstPromoter.

If you tell me your exact commission structure (e.g. “$50 per SQL + 20% of first-year ARR, with 3 affiliate tiers”) and whether you're using Salesforce or HubSpot, I can narrow it down to the best 2–3 platforms.

For a B2B SaaS with annual plans, where you specifically need tiered commissions + lead-based tracking, I’d shortlist these:

My pick: PartnerStack

If by lead-based tracking you mean something like:

Affiliate refers a prospect → prospect books a demo → becomes an opportunity → signs an annual contract → affiliate gets paid based on the milestone/value

then PartnerStack is probably the strongest fit. It explicitly supports event-based commissions for milestones such as demo completions and contract signings, CRM-connected lead tracking, and recurring commissions on subscriptions/renewals. partnerstack.com

It's particularly designed around B2B partner-sourced pipeline, rather than just affiliate clicks → purchases.

If you don't need that much infrastructure: FirstPromoter

FirstPromoter is compelling if your funnel is relatively straightforward. It supports tiered commission rates based on performance thresholds, as well as one-time, lifetime and recurring commissions. firstpromoter.com

I'd choose it over PartnerStack if you're primarily looking for:

• Affiliate → signup/customer attribution
• Different commission % at different volume levels
• Annual subscription commissions
• Stripe/Chargebee/etc. billing integration
• A simpler, more SaaS-native implementation

The key distinction

I'd make the decision based on what you mean by "lead-based":

A. Pay on qualified lead/demo/opportunity → PartnerStack
B. Pay when the referred lead becomes a paying annual customer → FirstPromoter
C. Complex attribution across CRM + multiple touchpoints + partner types → Everflow/PartnerStack

For a typical B2B SaaS selling $5k–$50k+ annual contracts, I'd lean PartnerStack if affiliates are really sales partners. For a more conventional affiliate program where partners send traffic and you pay on closed subscriptions, I'd lean FirstPromoter.

If you tell me your ACV, CRM (HubSpot/Salesforce/etc.), billing system (Stripe/Chargebee/etc.), and exactly what event triggers commission, I can narrow it to 2–3 platforms and compare the economics.

For a B2B SaaS with annual plans, I’d shortlist FirstPromoter and PartnerStack, with the right choice depending on what you mean by “lead-based.”

My pick: FirstPromoter

FirstPromoter is probably the closest match to your requirements. It explicitly supports tiered commission models, including rates that increase when affiliates hit volume thresholds. It can also attribute conversions to actual billing events rather than merely counting signups. firstpromoter.com

For example, you could structure:

• 1–5 qualified leads/month → 15%
• 6–15 → 20%
• 16+ → 25%
• Commission paid when the annual subscription actually converts
• Optionally recurring/lifetime commissions on renewals

It also supports first- or last-click attribution, configurable cookie windows, coupon-code attribution, and tracking of subscription events such as cancellations/refunds. firstpromoter.com

One important distinction: FirstPromoter's “multi-tiered commissions” can also mean affiliate-of-affiliate / parent-child commissions, rather than just performance tiers. It supports both concepts, so make sure the tiering model you need is the performance-based one if that's what you're after. help.firstpromoter.com

When I'd choose PartnerStack instead

PartnerStack is stronger if “lead-based” means B2B sales pipeline, rather than simply tracking affiliate leads.

PartnerStack is specifically built around B2B SaaS and supports event-based commissions, CRM-integrated/S2S attribution, clicks → trials → conversions → revenue, recurring commissions, and performance tiers. partnerstack.com

So if your affiliates refer prospects who may spend weeks/months in a sales funnel before buying an annual contract, I'd lean PartnerStack.

The decision I'd make

Self-serve annual SaaS + affiliates send signups/trials → FirstPromoter.

Sales-assisted B2B SaaS + affiliates send qualified leads/opportunities → PartnerStack.

If you tell me (1) your CRM, (2) billing system—Stripe/Paddle/Chargebee/etc., and (3) exactly what you mean by “lead” (demo request, MQL, SQL, or paid customer), I can narrow it down to the best 2–3 platforms and compare their pricing and implementation effort.

For a B2B SaaS with annual plans, I’d prioritize platforms that can handle:

• Tiered commissions (e.g., 10% for standard affiliates, 20% after $50k ARR sourced, different tiers by partner type)
• Lead-based attribution (demo requests, SQLs, opportunities, deal stages — not just closed-won purchases)
• Recurring revenue logic (renewals, upgrades, expansions)
• CRM integration (Salesforce/HubSpot-style pipeline tracking)

The strongest fits:

My shortlist for your scenario

1. If your sales motion is demo → sales call → contract → annual renewal:
Pick PartnerStack. It is designed around B2B SaaS partner motions rather than just affiliate links. You can reward partners for milestones like qualified leads, opportunities, closed deals, and recurring revenue. partnerstack.com

2. If customers self-serve and buy annual plans online:
Pick Rewardful (especially with Stripe/Paddle). It is simpler and handles recurring commissions well. www.rewardful.com

3. If you have many partner categories (affiliates + influencers + agencies + resellers):
Evaluate Impact.com.

A practical commission model many B2B SaaS companies use:

• Lead submitted: fixed bounty ($25–$200)
• Qualified opportunity: additional bounty ($100–$500)
• Closed annual contract: 10–30% of first-year ARR
• Renewal: optional 5–10% recurring commission
• Tier accelerator:
  • Tier 1: 10% up to $25k ARR sourced
  • Tier 2: 15% above $25k
  • Tier 3: 20% above $100k

If you tell me whether your sales motion is PLG/self-serve vs sales-led (demo + AE) and your CRM (HubSpot, Salesforce, etc.), I can narrow this to the best 2–3 options.

For B2B SaaS with annual contracts, I’d narrow it to PartnerStack vs. FirstPromoter.

My pick: PartnerStack

For your particular model, PartnerStack is probably the strongest fit. It supports event-based commissions—so you can reward a partner for things like qualified lead → demo → signed annual contract, rather than requiring an immediate purchase. It also connects partner-sourced leads to your CRM and can track progression through the sales cycle. partnerstack.com

That's important for B2B SaaS because the affiliate might generate a lead in January but the customer doesn't sign the $20k annual contract until March.

You could structure something like:

• Qualified lead: $50
• Sales-qualified opportunity: $150
• Closed annual contract: 10% of first-year ARR
• >$100k sourced ARR/year: 12%
• >$250k sourced ARR/year: 15%

PartnerStack also supports tiers, recurring commissions, and CRM/billing integrations, which makes it much more appropriate if partners influence deals rather than simply refer self-serve subscriptions. partnerstack.com

When I'd choose FirstPromoter instead

If your "leads" are really trial/signup → paid annual subscription, rather than a sales-assisted pipeline, I'd seriously consider FirstPromoter. It explicitly supports tiered commission models, with rates increasing when affiliates hit volume thresholds, and can tie commissions to actual billing events rather than just signups. firstpromoter.com

It is also substantially simpler/cheaper than PartnerStack; its published comparison shows plans starting around $49/month versus PartnerStack's enterprise-oriented pricing. firstpromoter.com

Rule of thumb:

• Sales-led B2B + CRM leads + annual contracts → PartnerStack
• Product-led SaaS + Stripe/Chargebee + affiliate referrals → FirstPromoter
• Very simple Stripe affiliate program → Rewardful

If you tell me your ACV, sales cycle, CRM (HubSpot/Salesforce/etc.), billing system, and whether commission is paid on leads, closed-won revenue, or both, I can recommend the exact platform and commission structure.

For a B2B SaaS selling annual plans, you’ll usually want a platform that can handle:

• Recurring or annual revenue attribution
• Tiered commission rules (e.g., 20% for standard affiliates, 30% after $50k ARR sourced)
• Lead-based tracking (not just paid conversions)
• Partner/agency workflows (common in B2B SaaS)
• CRM handoff (HubSpot/Salesforce/etc.)

The best fits depend on how complex your program is:

My shortlist for your case

If you sell $5k–$100k+ annual contracts and partners influence pipeline:
→ PartnerStack
It is designed around SaaS partnerships rather than just affiliate links. You can track partner-sourced leads, opportunities, and revenue outcomes. www.rewardful.com

If you have a self-serve SaaS motion with annual subscriptions:
→ Rewardful or FirstPromoter
Rewardful is particularly suited to subscription businesses because it tracks referrals tied to billing events, including recurring commissions and subscription changes. help.rewardful.com

If your commission logic looks like this:

• Partner A: 20% of first-year ARR
• Partner B: 25% after 10 deals
• Agency tier: 30% after $250k sourced revenue
• Pay on qualified opportunity → closed-won → renewal

I’d lean PartnerStack, Everflow, or Impact rather than a lightweight affiliate tool.

A typical B2B SaaS setup would be:

1. Lead created → affiliate/partner gets attribution credit
2. Opportunity created in CRM → partner gets pipeline visibility
3. Deal closed → commission calculated on ARR
4. Renewal/expansion → recurring or bonus commission rules applied

A few questions would change the recommendation:

1. What’s your average annual contract value (ACV)?
2. Are partners mostly content affiliates, agencies/consultants, or referral customers?
3. Do you need to pay on qualified leads, or only when a deal closes?

For a B2B SaaS with annual plans, I’d shortlist these three:

My pick: PartnerStack

PartnerStack is specifically built around B2B SaaS, rather than primarily ecommerce. It supports event-based commission models, recurring revenue, and full-funnel tracking from clicks through conversions and revenue. It also supports partner tiers. partnerstack.com

That's particularly useful if your funnel looks something like:

Affiliate → lead/demo → opportunity → annual contract → renewal

You can structure commissions around different events rather than simply "affiliate gets 20% of checkout."

FirstPromoter is the better lightweight option

If you don't need a big partner ecosystem, I'd seriously consider FirstPromoter. It supports percentage, flat, one-time, lifetime, and tiered commissions, and its subscription tracking handles billing events such as renewals, upgrades, downgrades and cancellations. firstpromoter.com

It even supports multi-tier affiliate structures (e.g. an affiliate recruiting another affiliate), although its current documentation limits that to three tiers. help.firstpromoter.com

Where Impact fits

Impact is the most flexible of the three for complicated attribution. Its Essentials plan explicitly supports tracking conversions, leads, app installs, bookings, etc., while higher tiers add API/offline tracking and more sophisticated payout incentives. impact.com

Bottom line:

• B2B sales + leads + annual contracts + partner ecosystem → PartnerStack
• Primarily affiliate-driven SaaS + straightforward implementation → FirstPromoter
• Complex enterprise attribution / multiple partner types → impact.com

If you tell me (1) whether affiliates get paid on a qualified lead, closed-won deal, or both, and (2) your commission tiers, I can narrow this down to the best platform and explain exactly how I'd configure it.

For a B2B SaaS selling annual plans, you’ll want something that can do more than cookie-based affiliate tracking. Look for:

• Lead attribution (visitor → demo/trial → qualified lead → closed-won)
• CRM integration (Salesforce/HubSpot)
• Recurring or annual commission logic
• Tiered commissions (e.g., 20% up to $50k ARR, 25% above, VIP tiers)
• Partner-specific rules (different payouts by partner type)

My shortlist:

My recommendation by stage:

• You have a sales-assisted motion (demos, SDRs, enterprise deals): choose PartnerStack. It is built around partner-sourced pipeline, not just affiliate links. partnerstack.com
• You are mostly self-serve SaaS with annual subscriptions: choose FirstPromoter. It is better suited to flexible commission formulas tied to subscription billing events. firstpromoter.com
• You’re early and need something lightweight: start with Rewardful and migrate later if partners become a major channel. www.rewardful.com

A common B2B SaaS commission setup these platforms can support:

• Registered lead: $50–$200 (optional)
• Qualified opportunity: $250–$1,000 (optional)
• Closed annual contract: 15–30% of first-year ARR
• Tier accelerator:
  • 1–5 deals/year: 20%
  • 6–20 deals/year: 25%
  • 20+ deals/year: 30%

One thing to verify before buying: whether “lead tracking” means a tracked form submission or true CRM lifecycle attribution. For B2B SaaS, the latter is usually what matters. partnerstack.com

If you share your ACV (e.g., $1k/year vs $50k/year) and whether sales calls are involved, I can narrow this to a single best fit.

For a B2B SaaS selling annual contracts, the key capabilities are:

• Tiered commissions (e.g. 15% until $50k ARR referred, then 20%)
• Lead-based tracking (credit partners for qualified leads, demos, or opportunities—not just online purchases)
• CRM integration (HubSpot, Salesforce, etc.)
• Support for long sales cycles and offline conversions
• Flexible payout rules (first payment, annual renewal, closed-won deal)

Here's how the leading platforms compare:

My recommendations

PartnerStack is probably the strongest fit if you're selling annual B2B SaaS contracts through demos and sales reps. It supports event-based commissions (for example: qualified lead → SQL → closed deal), CRM-connected attribution, recurring or one-time commissions, partner segmentation, and performance tiers. It was built around B2B SaaS partnerships rather than ecommerce. partnerstack.com

impact.com is ideal if you're running a broader partnerships strategy (affiliates, influencers, agencies, referral partners, strategic partners) and need sophisticated attribution across channels. It has excellent lead tracking but is generally aimed at larger organizations.

FirstPromoter is an excellent choice if your process is relatively straightforward and billing is handled through Stripe, Paddle, Chargebee, or Recurly. It supports tiered commission structures and recurring subscription events, but its strength is subscription lifecycle tracking rather than CRM-driven opportunity tracking. firstpromoter.com

If lead-based tracking is your priority

Look for a platform that can trigger commissions on CRM events such as:

• Form submission
• Marketing Qualified Lead (MQL)
• Sales Qualified Lead (SQL)
• Demo completed
• Opportunity created
• Closed Won
• First invoice paid

That generally points toward PartnerStack, impact.com, or Everflow rather than affiliate tools focused only on checkout attribution.

For your use case

If you're selling annual B2B SaaS with a sales-assisted funnel, I'd narrow it to:

1. PartnerStack — best overall balance of affiliate management, lead attribution, CRM integration, and tiered commissions.
2. impact.com — if you expect a large, enterprise-grade partner ecosystem.
3. FirstPromoter — if your sales cycle is simpler and you mainly need recurring commission logic tied to subscriptions.

If you can share:

• your CRM (HubSpot, Salesforce, Pipedrive, etc.),
• billing platform (Stripe, Chargebee, Paddle, NetSuite, etc.),
• and whether partners are sending leads or self-serve signups,

I can narrow it down to the best fit for your stack.

For a B2B SaaS with annual contracts, a sales-assisted funnel, tiered commissions, and lead-based attribution, I'd narrow the shortlist to these:

My recommendations

1. PartnerStack (best fit for most B2B SaaS)
If your sales cycle looks like:

Affiliate → Demo booked → Sales call → Closed annual contract

PartnerStack is designed for exactly that. It supports:

• Tiered commission structures (different rates by partner type or performance)
• Event-based payouts (demo booked, SQL, closed deal, renewal)
• CRM integrations (Salesforce, HubSpot)
• Lead tracking throughout the sales cycle
• Recurring and renewal commissions
• A marketplace of B2B SaaS partners to help recruit affiliates partnerstack.compartnerstack.com

This is the platform I see most often for companies selling $5k–$100k+ annual SaaS contracts.

2. impact.com (best enterprise option)

If you're expecting:

• agencies
• strategic partners
• influencers
• affiliates
• referral partners

all in one program, impact.com is extremely capable.

Pros:

• Sophisticated attribution
• Offline conversion support
• CRM integration
• Complex commission logic
• Global payouts

Cons:

• More expensive
• Longer implementation

3. Everflow

A great middle ground if your marketing team wants more control.

Strong for:

• server-to-server tracking
• lead attribution
• multiple commission rules
• custom events
• API-first workflows

If you want commissions like this…

Affiliate A
------------
Lead submitted:        $50
Qualified demo:       $150
Closed annual deal:   10%
$50k ARR customer:    12%
Top partner:          15%
Renewal:               5%

PartnerStack, impact.com, TUNE, and Everflow can all support this type of staged or event-based commission structure. PartnerStack specifically highlights flexible triggers, partner groups, and multi-level payout scenarios. partnerstack.compartnerstack.com

If your funnel is sales-assisted

Look for platforms that support:

• CRM-based attribution (not just cookies)
• Lead registration
• Offline conversion imports
• Opportunity-stage tracking
• Closed-won events
• Multi-touch attribution
• Renewal commissions

These capabilities matter more than basic click tracking when deals close weeks or months after the initial referral.

My overall picks

• Best overall for B2B SaaS: PartnerStack
• Best enterprise: impact.com
• Best flexible platform: Everflow
• Best for custom engineering teams: TUNE
• Best budget option for Stripe self-serve SaaS: Rewardful or FirstPromoter

If you can share:

• your typical ACV (e.g. $3k, $15k, $50k+),
• whether you're using HubSpot or Salesforce, and
• whether affiliates are paid on qualified leads, closed deals, or ARR,

I can narrow it down to the one that best fits your sales motion.

For a B2B SaaS selling annual contracts with a sales-assisted funnel, the key capabilities are usually:

• Lead-based attribution (not just self-serve purchases)
• CRM integration (HubSpot, Salesforce, etc.)
• Tiered commission structures (by partner level, volume, or partner type)
• Support for long sales cycles (60–180+ days)
• Recurring or one-time annual commission options
• Manual approval before payouts

Here's how the leading platforms compare:

1. PartnerStack (my top recommendation)

If your sales process looks like:

Affiliate → Demo booked → Sales rep closes → Annual contract → Commission

PartnerStack is one of the strongest options because it supports:

• CRM-connected lead tracking
• Event-based commissions (demo, SQL, closed deal, renewal)
• Different commission rates for different partner tiers
• Recurring or one-time payouts
• Partner segmentation (agencies, consultants, affiliates, resellers)
• A marketplace of B2B SaaS partners for recruitment

It's built specifically around B2B SaaS rather than ecommerce affiliate programs. partnerstack.com

Good fit if your ACV is roughly $3k–$100k+.

2. Impact.com

Impact is the most flexible if you have a sophisticated partner strategy.

It supports:

• Custom attribution rules
• Lead-based tracking
• Salesforce integration
• Multi-touch attribution
• Complex commission logic
• Different partner types under one platform

The trade-off is higher implementation effort and enterprise pricing.

3. FirstPromoter

A good option if:

• Stripe or Paddle is your source of truth
• Most revenue is subscription-based
• You don't need enterprise PRM features

It supports:

• Tiered commissions
• Recurring commissions
• Subscription lifecycle tracking
• Multiple commission models

However, it's generally stronger for subscription attribution than for complex CRM-driven partner management. help.firstpromoter.com

For annual-plan SaaS, I'd recommend commission rules like:

You can also create partner tiers such as:

• Silver → 15%
• Gold → 20%
• Platinum → 25%

or increase rates after hitting milestones like 10 or 25 closed deals.

My recommendations by company stage

• Seed to Series A (mostly self-serve): FirstPromoter or Tolt
• Sales-led B2B SaaS ($5k–50k ACV): PartnerStack
• Large enterprise with multiple partner motions (affiliates, agencies, resellers, technology partners): Impact.com

If you have a sales-assisted annual SaaS with deals flowing through HubSpot or Salesforce, PartnerStack is typically the strongest balance of lead tracking, tiered commissions, and B2B-focused workflows without the complexity of a full enterprise deployment.

For a B2B SaaS selling annual contracts (especially if your sales cycle involves demos, SQLs, and CRM stages rather than instant checkout), I'd prioritize platforms that support:

• Tiered commissions (performance-based or partner tiers)
• Lead-based attribution (not just purchases)
• CRM integration (HubSpot, Salesforce, etc.)
• Offline conversion tracking (closed deals after weeks/months)
• Flexible payout rules (qualified lead, demo booked, closed-won, renewal)

Here's how the leading options compare:

1. PartnerStack (my top recommendation)

This is the platform most purpose-built for B2B SaaS.

Strengths:

• Tiered commission structures
• Pay for demo booked, opportunity created, closed deal, renewal, or expansion
• CRM syncing so affiliates receive credit as leads move through the funnel
• Built-in partner marketplace for recruiting affiliates
• Handles recurring and subscription commissions well
• Good partner experience and onboarding partnerstack.com

Ideal if:

• Annual contracts
• Sales-assisted motion
• HubSpot or Salesforce
• Agencies, consultants, influencers, and referral partners

2. Everflow

If attribution and customization matter more than marketplace access, Everflow is extremely strong.

Highlights:

• Native tiered commission engine
• Performance tiers (e.g. 5 deals = 15%, 20 deals = 20%)
• Lead, demo, MQL, SQL, opportunity, and revenue tracking
• Multi-touch attribution
• Excellent reporting
• Flexible API for custom workflows www.everflow.io

Great when:

• Marketing wants deep reporting
• Complex commission logic
• Multiple partner types (affiliates, agencies, resellers)

3. Impact.com

Best suited if you're running a large, mature partnership program.

Pros:

• Enterprise-grade reporting
• Sophisticated commission rules
• Lead and conversion tracking
• Strong fraud prevention
• Large ecosystem

Cons:

• More complex to implement
• Often overkill for a growing SaaS company

Example commission structure

For an annual SaaS product, many companies use something like:

Both PartnerStack and Everflow support these kinds of event-based commission models. www.everflow.iopartnerstack.com

My recommendation by company stage

• Early-stage (<$5M ARR): FirstPromoter or Rewardful if you primarily need subscription tracking and have a straightforward sales flow.
• Growth ($5M–50M ARR): PartnerStack is the strongest fit for most B2B SaaS companies because it combines CRM-aware lead tracking, flexible commissions, and access to a partner network. partnerstack.com
• Enterprise or complex partner programs: Everflow if advanced attribution and custom partner management are higher priorities than marketplace access. www.everflow.iopartnerstack.com

If you can share:

• your approximate ARR,
• your CRM (HubSpot or Salesforce),
• and whether you pay affiliates on qualified leads, closed deals, or both,

I can narrow it down to the best fit and point out the trade-offs you'll actually encounter during implementation.
