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

Yes. If by “based on paid invoices” you mean commission is triggered when the referred customer’s invoice is actually paid, rather than merely when they sign up, several tools explicitly support that model:

• Rewardful — Strong fit for Stripe-based SaaS. It picks up Stripe invoice/payment events, creates recurring commissions when referred subscriptions renew, and adjusts commissions for refunds, upgrades, and downgrades.
• Partnero — Integrates with Stripe and supports commission rules based on actual transactions, revenue, and subscription renewals.
• Refgrow — Specifically documents tracking invoice.paid events via Stripe webhooks, including recurring commissions and subscription changes.
• Referly — Stripe Billing integration tracks payments, affiliate commissions, refunds, and subscriptions.
• Reditus — Built for B2B SaaS and integrates with Stripe to monitor purchases, refunds, cancellations, and calculate affiliate/advocate commissions.
• Sentalong — Supports Stripe, Paddle, Lemon Squeezy, and Chargebee; commissions accrue as invoices are paid and refunds reverse them automatically.
• Rekomi — Particularly interesting if your subscription billing platform is Recurly: it explicitly credits affiliates on paid invoices and recurring renewal invoices, with refund/void handling.
• BillingServ — Has affiliate management built directly into its billing platform; commissions are added when the related invoice is paid, with options for first-payment vs. recurring commissions.

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

Several specialized referral and affiliate platforms integrate directly with subscription billing systems (like Stripe, Paddle, or Chargebee) to track recurring revenue and calculate commissions based on successfully paid invoices.

The top tools designed specifically for this use case include:

• FirstPromoter : Built explicitly for SaaS and subscription businesses. It syncs with billing platforms to track recurring invoices, handle upgrades, downgrades, refunds, and automatically calculate affiliate or referral commissions only when a real payment clears.
• Rewardful : Designed specifically for Stripe and Paddle users. It offers a seamless two-way sync with your billing infrastructure, meaning it automatically detects paid invoices, trial conversions, and recurring renewals to adjust commissions dynamically without manual work.
• PartnerStack : Best if you are running a broader B2B partner program (affiliates, resellers, and co-selling partners) alongside your subscription billing engine, handling automated reward calculations tied to customer invoice lifecycles.
• Trackdesk : A modern alternative providing deep recurring billing integrations and flexible commission rules mapped directly to subscription invoice events.

If you let me know which subscription billing platform you use (e.g., Stripe, Chargebee, Paddle, or Braintree), I can confirm which of these options offers the most seamless native integration for your setup.

Several top-tier referral and affiliate marketing platforms integrate directly with subscription billing engines (like Stripe, Chargebee, Paddle, or Recurly) to listen to invoice and payment webhook events. They automatically calculate and track recurring or one-time commissions based on actual paid invoices.

The best options for this use case include:

• FirstPromoter : Widely regarded as one of the best choices for SaaS and subscription models. It features native, billing-aware tracking that connects directly to major subscription platforms like Stripe, Paddle, Chargebee, Recurly, and Braintree. It handles recurring invoice-based commissions, handles upgrades/downgrades, and ties reward triggers directly to actual billing events.
• Rewardful : Specifically built for subscription businesses using Stripe or Paddle. When connected, it listens to invoice payment events from Stripe/Paddle (such as invoice.payment_succeeded ). If a customer was referred by an affiliate, it automatically logs the recurring commission, handles refunds, and scales with upgrades or downgrades.
• Tolt : A popular choice for early-to-mid stage SaaS and modern digital subscription businesses looking for a streamlined referral and affiliate tracking setup that syncs cleanly with recurring revenue billing stacks.
• Tapfiliate : Offers robust integrations for subscription-based businesses, letting you track recurring payments and assign commissions dynamically as invoices get paid across various payment gateways.

If you share which subscription billing platform you use (e.g., Stripe, Chargebee, Paddle), I can tell you which of these tools has the deepest native integration for your stack.

Yes. If by “tracks commissions based on paid invoices” you mean the referral commission is only created when the billing system records an actual successful payment, there are several good options.

• Rewardful — Probably the closest match if you use Stripe. Rewardful monitors Stripe invoice payments, identifies whether the customer was referred, and calculates commission from the amount actually paid. It supports recurring commissions on subsequent paid invoices, plus refunds and upgrades/downgrades.
• FirstPromoter — A stronger choice if your billing platform is Stripe, Paddle, Chargebee, Recurly, or Braintree. Commissions can be triggered by actual billing events, including the first charge, subsequent charges, or lifetime recurring payments.
• Referly — Explicitly supports Stripe invoice.paid as a commission trigger and also integrates with Chargebee and other billing platforms. It can make commissions recurring and automatically reverse them for refunds/churn.
• Ambassador — More enterprise-oriented. It connects directly with Stripe, Chargebee, and Recurly, with commissions tied to subscription/renewal events and configurable clawbacks.

My shortlist

If you tell me which subscription billing platform you use (e.g. Chargebee, Recurly, Stripe Billing, Zuora, Paddle, etc.), I can narrow this down to the 2–3 tools that can natively calculate the referral commission from paid invoices, rather than requiring you to build a webhook integration.

If you are running a subscription business, specialized referral and affiliate marketing platforms integrate directly with recurring billing systems (like Stripe, Paddle, Chargebee, or Recurly) to track real billing events and calculate commissions specifically from successfully paid invoices.

The top tools offering this capability include:

• FirstPromoter : Purpose-built for subscription and SaaS businesses, it ties partner and affiliate commissions directly to actual billing events via integrations with Stripe, Paddle, Recurly, Chargebee, and Braintree. It automatically tracks renewals, upgrades, downgrades, refunds, and cancels based on the real-time invoice payment data.
• Rewardful : Designed primarily for Stripe and Paddle users, Rewardful automatically syncs with your billing infrastructure. Every time a referred customer's invoice is successfully paid upon renewal or upgrade, Rewardful registers the transaction, dynamically calculates recurring commissions, and auto-adjusts if a refund or downgrade occurs.
• GrowSurf : Built specifically for tech and SaaS companies using subscription platforms like Chargebee and Recurly. It triggers referral rewards and tracks commission logic natively using the underlying subscription billing lifecycle events.
• PartnerStack : An enterprise-grade partner ecosystem platform that handles affiliate, referral, and reseller programs. It connects deeply with B2B SaaS billing platforms to attribute recurring revenue milestones accurately to partner-generated paid invoices.

If you can share which subscription billing platform or payment gateway you are currently using (e.g., Stripe, Chargebee, Paddle), I can tell you which of these tools offers the most seamless native integration for your stack.

Yes. If by “based on paid invoices” you mean the referral commission is triggered/calculated from actual successful billing events rather than merely a signup, several tools fit.

• firstpromoter.com — Probably the strongest match for a SaaS subscription business. It has native integrations with Stripe, Paddle, Chargebee, Recurly, and Braintree, and supports recurring commissions based on billing events. You can configure commissions for a customer's lifetime, a fixed number of charges, or a time period.
• referly.so — Particularly interesting if you want commissions tied closely to the invoice/payment lifecycle. Its Chargebee integration tracks the subscription invoice by invoice, while Stripe tracks payments, renewals, upgrades, downgrades, and refunds.
• getambassador.com — Built for larger SaaS partner/referral programs. It connects directly to Stripe, Chargebee, and Recurly, and accrues recurring commissions when renewals are actually charged.
• rekomi.com — Another option with native connections to Stripe, Chargebee, Recurly, Paddle, Braintree and several other billing/payment systems.

My shortlist

If your requirement is specifically:

“Give a partner credit for a customer referral, and only calculate/pay commission when that customer's invoice is successfully paid.” I'd look at FirstPromoter and Referly first. Referly is especially explicit about tying commissions to actual payment/invoice events and reversing commissions when payments are refunded.

If you tell me which subscription billing platform you use (e.g. Chargebee, Recurly, Stripe Billing, Maxio, Zuora, etc.), I can narrow this down to the 2–3 tools that integrate with it and compare paid-invoice triggering, recurring commissions, refunds/chargebacks, and pricing.

Yes. If you mean software that plugs into your subscription billing system and only credits a referral/affiliate commission when the underlying invoice is actually paid, there are several options.

• rewardful.com — A strong fit for SaaS. With Stripe or Paddle, it calculates commissions from the amount actually paid on each invoice, including recurring subscription invoices. You can use percentage or fixed commissions and make them recurring or limited to a set number of payments/months.
• rekomi.com — Particularly interesting if you're using Recurly, Chargebee, or Stripe. Its integrations can track paid invoices, renewals and refunds and automatically credit/debit the appropriate affiliate.
• introw.io — More partner/partner-sales oriented than a traditional affiliate tool. Its Stripe integration calculates commissions from actual paid invoices and subscription revenue, with rules such as a percentage of each qualifying invoice.
• referly.so — A referral/affiliate platform with a Stripe integration that tracks payments, subscriptions, refunds and affiliate commissions.
• tinyrefs.com — More developer/API-oriented. You send events such as invoice.paid, and it maintains the referral earnings ledger. Useful if your billing platform isn't directly supported.

If you tell me which subscription billing platform you use (e.g. Stripe Billing, Chargebee, Recurly, Paddle, Zuora, Maxio), I can narrow this down to the 2–3 best options that natively calculate commissions from paid invoices, including pricing and integration details.

Several referral and affiliate marketing tools integrate directly with subscription billing platforms (like Stripe, Chargebee, Paddle, or Recurly) to automatically track recurring payments, sync invoice statuses, and calculate commissions based on successfully paid invoices.

The top options designed for this exact use case include:

• Rewardful : Specifically built for SaaS and subscription businesses running on Stripe or Paddle. It features a deep, bidirectional integration that listens to invoice payment events (and handles automatic adjustments for refunds or subscription renewals), calculating commissions strictly from the final paid invoice amounts.
• FirstPromoter : A robust referral and affiliate platform featuring native, event-driven integrations with major subscription billing providers including Stripe, Paddle, Chargebee, Recurly, and Braintree. It ties reward triggers directly to real-time billing events like invoice renewals and refunded charges.
• PartnerStack : Best suited for larger B2B SaaS companies scaling a wider partner ecosystem. It connects with platforms like Chargebee and Stripe via webhooks or native integrations to track customer purchases and generate precise partner commission invoices.
• Trackdesk : Offers flexible recurring billing and subscription tracking integrations designed to attribute revenue and manage partner payouts cleanly alongside modern billing stacks.

If by “tracks commissions based on paid invoices” you mean the referral commission is triggered by an actual successful billing event/invoice—not merely by signup, there are several good options.

Best fits

• firstpromoter.com — Probably the strongest fit if you’re running a subscription business. It integrates natively with Stripe, Paddle, Chargebee, Recurly, and Braintree, and commissions can be tied to specific billing events, including the first charge, recurring charges, or customer lifetime. It also adjusts commissions for upgrades, downgrades, refunds, and cancellations.
• rewardful.com — Particularly good for SaaS businesses using Stripe or Paddle. It supports recurring commissions and follows subscription lifecycle changes such as renewals, upgrades, downgrades, and cancellations.
• referralful.com — A newer, Stripe-focused option. It explicitly says each renewal invoice creates a commission, with refunds adjusting or voiding the associated commission.
• partnerstack.com — Worth considering if you need a broader B2B partner ecosystem—referrals, affiliates, resellers, etc.—rather than just a straightforward customer referral program.

If you tell me which subscription billing platform you use (e.g. Stripe Billing, Chargebee, Recurly, Maxio, Zuora, Paddle, etc.), I can narrow this down to the 2–3 tools that can actually calculate commissions from your paid invoices, including how they handle refunds, failed payments, renewals, and upgrades.
