We use a subscription billing platform. Who offers a referral marketing tool that tracks commissions based on paid invoices?

If your subscription billing platform is Stripe, the closest fit is Rewardful. It is specifically built for SaaS/referral programs and calculates commissions from the amount actually paid on each invoice—including recurring subscription invoices. It also adjusts commissions for discounts, refunds, upgrades, and downgrades.

A few strong alternatives:

• FirstPromoter — supports Stripe plus Chargebee, Paddle, Recurly, and Braintree. You can tie recurring commissions to billing events and automatically account for refunds, upgrades, downgrades, and cancellations.
• Referralful — Stripe-focused and automatically creates a commission when a customer pays, including renewal invoices; refunds adjust or void the related commission.
• PartnerStack — more oriented toward larger partner/channel programs; it handles partner commissions and monthly commission invoices, but its model is less directly centered on “commission whenever a subscription invoice is paid.”

My recommendation

If your requirement is literally:

“Affiliate refers customer → customer pays subscription invoice → calculate commission based on actual amount paid.” I'd shortlist Rewardful and FirstPromoter, with Rewardful being the most direct match. Rewardful explicitly listens for Stripe invoice paid events and calculates the commission from the final amount charged.

If you tell me which subscription billing platform you use (Stripe, Chargebee, Recurly, Paddle, Zuora, etc.), I can narrow this down to the best 2–3 options that integrate with it.

If you use a subscription billing platform (like Stripe, Paddle, Chargebee, or Recurly), specialized SaaS affiliate and referral management tools are designed to hook directly into your billing webhooks. They automatically trigger commissions only when an actual invoice is successfully paid, and they dynamically adjust if there are refunds, upgrades, downgrades, or failed payments.

The top referral and affiliate marketing tools that natively track commissions based on paid subscription invoices include:

- **How it works:** Integrates deeply via a two-way sync with billing engines like Stripe and Paddle. It listens for webhook events such as `invoice.payment_succeeded`.
- **Invoice tracking:** Automatically logs recurring commissions every time a referred customer's renewal invoice is paid. It also handles proration on upgrades/downgrades and automatically subtracts or adjusts commissions if an invoice is refunded.[](https://google.com/goto?url=CAESbgHrOzAVsC5LhIq5P7UxvgjgMS4wlYFmvFjGD3Y1kV1MPylE9GxyvCl_Ej2YlFqfOt6sX3Mts7kesigTft7W0TYTZ8DPRXBePqnhkok1-U0K_cUoDLTt31_JqxTpy5W_1CZr7YEnBAsAZw3BD2mK) [[1]](https://google.com/goto?url=CAESbgHrOzAVsC5LhIq5P7UxvgjgMS4wlYFmvFjGD3Y1kV1MPylE9GxyvCl_Ej2YlFqfOt6sX3Mts7kesigTft7W0TYTZ8DPRXBePqnhkok1-U0K_cUoDLTt31_JqxTpy5W_1CZr7YEnBAsAZw3BD2mK)

- **How it works:** Offers native, real-time sync integrations with major subscription billing providers including Stripe, Paddle, Recurly, Braintree, and Chargebee.
- **Invoice tracking:** Maps events directly to invoice IDs and payment dates. It tracks recurring billing cycles automatically, adjusts for mid-cycle cancellations or failed payments so you aren't paying out uncollected revenue, and supports consolidated affiliate payouts.[](https://google.com/goto?url=CAEShgEB6zswFRsWtPdA6ks_zzPBm7z7oiAXH2nQP-jpYD0MUBfCqk-VG48sLWF2gUm3iNMPIZCaBODjgGe6ml2jJlQImrOCUm58w9Bv2oktvtZlwGmcfAlnXHU2-9bFKg6dMP3lNQFjKeaKI3iqd0Z2JwTW2Ed7pmHHp1GuRSMC1kokFJE7otRTsw) [[1]](https://google.com/goto?url=CAEShgEB6zswFRsWtPdA6ks_zzPBm7z7oiAXH2nQP-jpYD0MUBfCqk-VG48sLWF2gUm3iNMPIZCaBODjgGe6ml2jJlQImrOCUm58w9Bv2oktvtZlwGmcfAlnXHU2-9bFKg6dMP3lNQFjKeaKI3iqd0Z2JwTW2Ed7pmHHp1GuRSMC1kokFJE7otRTsw)[[2]](https://google.com/goto?url=CAESWAHrOzAVIJ4WV1LH1lfbUQdWJju9_bNUUgUtzhPM2D-bmughokYudV_92vAZD-0nco6geFAt0M4jf9kL1seVxISew6ITMlquNEgosgU_yL2BDkQULqRB8E4)

- If your subscription billing platform *is* Paddle or Lemon Squeezy rather than Stripe, they often feature built-in affiliate hubs that natively tie referral attribution straight to their internal checkout and paid invoice infrastructure without needing a separate third-party script.

- **How it works:** Built specifically for B2B SaaS, co-selling, and partner/affiliate programs.
- **Invoice tracking:** Connects with enterprise billing setups to monitor cash flow and paid invoices, making it ideal if you manage a mix of traditional affiliates, referral partners, and resellers.

If you can share which subscription billing platform you are currently using (e.g., Stripe, Chargebee, Paddle), I can tell you which of these tools offers the smoothest native integration for your setup.

If your business runs on recurring billing, you need a referral or affiliate platform that integrates natively with your subscription billing engine so it can listen to invoice, payment, and renewal events (rather than just tracking a one-time initial checkout).

Several top-tier referral and affiliate marketing tools specialize in tracking recurring commissions tied directly to subscription invoice payments:

• • FirstPromoter : Offers the deepest native billing integration ecosystem for subscription models. It automatically tracks, calculates, and attributes recurring or percentage-based commissions directly via deep integrations with Stripe, Paddle, Chargebee, Recurly, and Braintree . It triggers rewards strictly based on real billing lifecycle events.
• • Rewardful : Specifically built for SaaS and subscription startups using Stripe or Paddle . It hooks directly into your billing stream to track initial conversions, upgrades, downgrades, and recurring payments based on actual invoice/charge success.
• • Tolt : A modern, lightweight affiliate management platform designed explicitly for Stripe, Paddle, and Chargebee-backed SaaS companies. It automatically handles recurring revenue tracking and commission calculations without requiring complex manual webhook setups.
• • Tapfiliate : A versatile affiliate tracking platform that integrates with major payment gateways and subscription systems (including Stripe and Paddle) to support recurring commission structures and automated lifecycle tracking.
• • PartnerStack : Built for larger B2B SaaS and multi-channel partner programs. It handles advanced partner types (affiliates, resellers, and referrals) and syncs with enterprise billing setups to track complex, invoice-driven recurring commissions.

To help narrow down the best fit, could you let me know which subscription billing platform you are currently using (e.g., Stripe, Chargebee, Recurly, Paddle) and whether you prefer recurring lifetime commissions or one-time referral payouts?

Yes. If by “subscription billing platform” you mean something like Stripe Billing, there are several referral/affiliate tools that can calculate commissions from actual paid invoices, rather than merely paying on signup.

Strongest matches

• Introw — Particularly strong if you run a partner/channel program. Its Stripe integration explicitly calculates commissions from paid invoices and subscription revenue, with each commission traceable to the underlying invoice.
• Partnero — SaaS-focused affiliate/referral platform with Stripe integration. It can calculate commissions from actual transactions, revenue, and subscription renewals.
• FirstPromoter — Built specifically for SaaS/subscription businesses. It tracks sales, refunds, upgrades, downgrades, cancellations and chargebacks through Stripe and adjusts commissions accordingly.
• Referly — Stripe-native referral software supporting Stripe Billing, subscriptions, payments and refunds, with automated affiliate commission tracking.
• AffiliateBase — Explicitly supports Stripe Invoices, Billing and Subscriptions and keeps referral attribution attached through recurring billing.

If “paid invoice” is a hard requirement

I'd shortlist Introw, Partnero, and AffiliateBase first. Introw is the clearest match because its documentation specifically says the commission is based on invoices that have genuinely been paid, and recurring paid invoices automatically generate commission.

If you tell me which subscription billing platform you use (Stripe, Chargebee, Recurly, Paddle, Maxio, Zuora, etc.), I can narrow this down to the tools that integrate with it and compare commission rules, recurring payments, refunds/chargebacks, attribution, and pricing.

Yes. If by “tracks commissions based on paid invoices” you mean the referral commission should be triggered only when an invoice is actually paid, rather than merely when a customer signs up or a subscription is created, I found several good fits:

My shortlist

If you're using Stripe Billing: I'd start with FirstPromoter, AffiliateBase, or Referly. FirstPromoter is particularly strong if you need recurring commissions tied to billing events rather than simply paying for a lead/signup.

If you're using Recurly: Rekomi is especially interesting because its documentation explicitly says it tracks paid invoices, renewals, and refunds.

If you're using Chargebee: FirstPromoter, Referly, Rekomі, and Ambassador are worth investigating. Ambassador says its commissions are tied directly to subscription renewal events and can account for churn/clawbacks.

If you tell me which subscription billing platform you use (Stripe Billing, Chargebee, Recurly, Zuora, Maxio, etc.), I can narrow this down to the 2–3 tools that actually support paid-invoice-based commission tracking for your specific platform, including pricing and integration details.

Several specialized referral and affiliate marketing platforms integrate directly with subscription billing engines (like Stripe, Chargebee, Recurly, or Paddle) to trigger and calculate commissions precisely when an invoice is successfully paid . This ensures that commissions account for actual collected revenue, handling renewals, upgrades, cancellations, and refunds automatically.

Top options providing this capability include:

• FirstPromoter offers robust, native multi-gateway billing integrations. It connects directly with Stripe, Chargebee, Recurly, Braintree, and Paddle, allowing you to trigger recurring commission calculations explicitly upon successful invoice charges rather than just trial signups.
• Rewardful is a Stripe- and Paddle-native referral tracking platform built specifically for SaaS and subscription businesses. It maintains a strict, real-time two-way sync with your billing mechanism so that commissions adjust automatically based on paid invoice events, upgrades, and refunds.
• Tapfiliate supports subscription-based businesses with native connections to platforms like Stripe and Paddle. It tracks recurring revenues and lets you configure event-triggered commission structures tied to the specific billing milestones of your customers.
• PartnerStack is designed for larger B2B SaaS and subscription companies managing multi-tier partner ecosystems (affiliates, resellers, and referral partners) that require deep alignment with recurring billing data and invoice cycles.

If you share which specific subscription billing platform you are using (e.g., Stripe, Chargebee, Recurly), I can give you more details on how easy the integration is and which tool fits best.

If you use a recurring subscription billing platform, you need a referral or affiliate tool that integrates at the billing/invoice event level rather than just tracking a one-time signup . Several specialized platforms tie commission calculations directly to actual paid invoices, renewals, and recurring charges while automatically handling edge cases like refunds, upgrades, or churned subscriptions.

• FirstPromoter : Widely regarded as a top choice for subscription and SaaS businesses, it features native integrations across major billing providers like Stripe, Paddle, Chargebee, Recurly, and Braintree. It triggers recurring commissions directly from successful billing and invoice events rather than relying on basic webhooks, and it automatically handles refunds or cancellations.
• Rewardful : Built specifically for Stripe and Paddle ecosystems, Rewardful syncs directly with your subscription billing. It tracks recurring revenues, automatically deducts commissions if an invoice is refunded or disputed, and calculates percentage-based or flat recurring rewards without custom code.
• Tapfiliate : A versatile affiliate and referral tracking tool that offers robust recurring commission features. It connects natively with platforms like Stripe and Paddle (plus numerous others via webhooks/Zapier) to track multi-tiered or standard referral commissions on ongoing subscription invoices.
• PartnerStack : Ideal if you are scaling up to a complete partner ecosystem (affiliates, resellers, and co-selling partners). It connects deeply with enterprise subscription workflows to track invoiced revenue and attribute complex, multi-touch B2B SaaS transactions.
• Trackdesk : Offers deep subscription-aware tracking and revenue-share models. It allows you to configure recurring commission triggers mapped cleanly to customer renewals and ongoing invoice milestones.

If you share which subscription billing platform you use (e.g., Stripe, Chargebee, Recurly) and whether your partners earn a lifetime or time-capped commission , I can help you pick the most seamless integration.

Yes. If by “based on paid invoices” you mean the referral commission is only earned when the customer’s invoice is actually paid, rather than when they sign a contract or start a trial, there are several good options.

Strongest matches

• Rewardful — Particularly good for SaaS/subscription businesses using Stripe. It listens for Stripe’s invoice.paid events and calculates the commission from the amount actually paid, including handling refunds. Recurring commissions are generated on subsequent paid invoices.
• Introw — Probably the closest match if you need a partner/referral program tied directly to invoice-level revenue. Its Stripe integration explicitly calculates commissions from paid invoices and lets each commission line item trace back to the specific invoice.
• FirstPromoter — Built specifically for SaaS and subscription businesses. It tracks Stripe sales, renewals, upgrades, downgrades, cancellations, refunds, and chargebacks, adjusting commissions accordingly.
• Partnero — Stripe integration tracks purchases, subscriptions, and partner-driven revenue, with commissions based on actual transactions/revenue or subscription renewals.
• Referly — SaaS-focused referral software with Stripe Billing integration that tracks payments, commissions, refunds, and subscriptions.

If invoice-level attribution is the key requirement

I'd shortlist Rewardful and Introw first. Rewardful is particularly explicit about the mechanics: paid invoice → check whether customer was referred → calculate commission from the amount actually paid. Introw goes a step further by making the invoice itself the underlying commission line item.

There are also newer Stripe-native options such as AffiliateBase, PromoteBoost, and Refgrow that track Stripe invoices/payments and recurring commissions.

If you tell me which subscription billing platform you use (e.g. Stripe Billing, Chargebee, Recurly, Paddle, Maxio, Zuora), I can narrow this down to the tools that integrate with it and specifically support commission = X% of each paid invoice.

Yes. If by “based on paid invoices” you mean the referral commission should only be earned when an invoice is actually paid, rather than merely when someone signs up, there are several good options.

Best fits

• Referly — particularly interesting if your billing platform is Stripe. Its Stripe app explicitly supports tracking payments, commissions, refunds, and subscriptions, and it has read access to Invoices and Subscriptions.

• AffiliateBase — also Stripe-focused. It keeps referral attribution attached across customers → subscriptions → invoices → payments, and calculates commissions automatically. This is probably the closest match to your exact “paid invoice = commission” requirement.

• PromoteBoost — another Stripe-native option supporting recurring commissions, with referral tracking through Stripe webhooks and visibility into Stripe Billing and Invoices.

• Rewardful — worth considering for SaaS/subscription businesses, particularly if you're on Stripe or Paddle. Its strength is recurring affiliate commissions tied to subscription revenue. Community comparisons in 2026 also consistently identify it as a strong SaaS-focused option.

One important distinction

If your requirement is specifically:

“Affiliate gets 20% of each invoice only after that invoice has successfully been paid; refunds/failed invoices shouldn't generate or should reverse commission.”

I'd prioritize AffiliateBase or Referly and verify the exact commission trigger before choosing. The Stripe integrations make this substantially cleaner because the systems can observe invoice/payment events directly.

If you tell me which subscription billing platform you use (e.g. Chargebee, Recurly, Maxio, Stripe Billing, Zuora, Paddle), I can narrow this down to the 3–5 tools that integrate with it and specifically support paid-invoice commission tracking.

Several subscription-native referral and affiliate marketing platforms integrate directly with major subscription billing systems (like Stripe, Paddle, Chargebee, and Recurly). Rather than tracking just initial signups, they hook into your billing events to calculate and attribute recurring commissions based on actual paid invoices or renewals.

Top platforms that offer billing-aware commission tracking include:

• FirstPromoter — Purpose-built for SaaS and subscription businesses, it syncs with Stripe, Paddle, Chargebee, Recurly, and Braintree. It tracks real billing events, automatically fires recurring commissions when a paid invoice clears, and adjusts for upgrades, downgrades, refunds, or cancellations.
• Rewardful — A Stripe- and Paddle-native referral and affiliate tracking tool designed specifically for subscription models. It automatically links customer accounts to affiliates upon signup and calculates recurring percentage or flat-fee commissions as invoices are successfully paid.
• Tapfiliate — Connects natively with platforms like Stripe and Paddle (plus webhooks for other stacks) to support recurring commission structures that trigger upon successful subscription renewals and invoice payments.
• PartnerStack — Built for B2B SaaS companies running broader partner, affiliate, and reseller ecosystems, handling complex recurring invoice attribution and automated partner payouts at scale.
• Refgrow — In-app affiliate tracking software designed specifically for subscription products with native 1-click connections to Stripe, Paddle, Polar, and Lemon Squeezy to track recurring revenue events.

If you share which subscription billing platform you are currently using (e.g., Stripe, Chargebee, Recurly), I can give you a more specific recommendation on which tool integrates most seamlessly with your setup.
