ChatGPT answers, unedited

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.
