If you're a solo founder selling subscriptions, I'd narrow it to Rewardful, FirstPromoter, and Tolt. For most founders, Rewardful is the easiest default—especially if you're using Stripe. Rewardful Track360

My ranking

🥇 I'd pick Rewardful

If your stack is Stripe + subscriptions, Rewardful is probably the best fit for a solo founder.

It handles referral links and subscription attribution through Stripe, and recurring revenue can generate recurring affiliate commissions without you having to reconcile everything manually. Rewardful Help Center Rewardful

The particularly nice part for a one-person business is Managed Payouts: Rewardful can consolidate the commissions and distribute them to affiliates, rather than you manually paying a bunch of people every month. It currently charges a 3% processing fee for that payout service. Rewardful Help Center

Rewardful's published entry pricing is around $49/month, with no additional percentage fee on affiliate revenue on the standard plans, although plan limits apply. The Subscription Guide

🥈 FirstPromoter if you want more flexibility

I'd choose FirstPromoter instead if you're using Paddle, Chargebee, Recurly, Braintree, or Stripe, or if you want sophisticated commission rules.

For example, it can do:

• 30% commission for the first 12 months
• 20% thereafter
• lifetime recurring commission
• fixed number of recurring payments
• one-time commissions

It natively tracks recurring commissions across Stripe, Paddle, Chargebee, Recurly and Braintree. FirstPromoter

Its payout system can also automate payments through PayPal or Stripe, or let you export a CSV and pay manually. FirstPromoter

🥉 Tolt

Tolt is worth considering if your priority is a clean, modern, lightweight affiliate dashboard and you don't need the broader billing integrations of FirstPromoter.

Current comparisons put it around $69/month, with recurring revenue support and automated payouts; automated payouts carry a 2% fee according to recent pricing comparisons. The Subscription Guide Affitor

What I would do in your shoes

Stripe subscription SaaS → Rewardful.

Paddle/Chargebee/Recurly or complicated commission rules → FirstPromoter.

Very simple program + slick UX → Tolt.

I would not start with PartnerStack or impact.com as a solo founder unless you specifically need their partner marketplace/enterprise capabilities. They're solving a much bigger problem than "I need affiliate links, recurring commissions, and easy payouts." Track360

If you tell me (1) Stripe/Paddle/etc., (2) your monthly subscription price, and (3) roughly how many affiliates you expect, I can tell you which one is cheapest and simplest for your specific setup.

Yes. For a SaaS product that needs to attribute web referrals + in-app signups and then pay recurring commissions on subscriptions, I’d shortlist these:

My recommendation: FirstPromoter

For your specific requirement, FirstPromoter looks particularly well aligned. It supports recurring, one-time, lifetime and tiered commissions, and its attribution can be tied to actual billing events rather than merely the initial signup. It supports Stripe, Chargebee, Paddle, Recurly and Braintree, plus API integration for custom setups. FirstPromoter FirstPromoter

The important part for web + in-app is that you can have the referral captured on the website, persist the referral/affiliate ID with the user account, and then send the eventual subscription/billing event back through the API/webhooks. FirstPromoter explicitly supports custom websites/apps through its API and webhooks. FirstPromoter FirstPromoter

A typical architecture would be:

Affiliate link
     ↓
Your website
     ↓
Capture affiliate_id / referral_id
     ↓
User creates account
     ↓
Persist referral_id on user/account
     ↓
User later signs up / upgrades in your app
     ↓
Your backend → affiliate platform
     ↓
Subscription/payment event
     ↓
Recurring commission
     ↓
Affiliate payout

That is preferable to relying solely on browser cookies, because the user identity becomes the bridge between the web referral and the in-app conversion.

Rewardful is the other one I'd seriously consider

If you're using Stripe, Rewardful is very compelling. It automatically tracks recurring commissions, upgrades, downgrades and cancellations from Stripe, and supports both no-code and custom-code integrations. Rewardful

So I'd narrow it down to:

• FirstPromoter → best if you want more sophisticated attribution, billing-provider flexibility, embedded/in-product partner experience, and API/webhook control.
• Rewardful → best if you're primarily Stripe + SaaS and want the simplest implementation.
• Tolt → worth evaluating if you want a SaaS-focused alternative with a relatively simple operating model.
• PartnerStack → consider when you're building a serious B2B partner ecosystem rather than just an affiliate/referral program.
• impact.com → consider when you expect a much broader, enterprise partnership strategy.

One particularly important question before choosing is how your in-app signup works. If you tell me whether you're using Stripe/Chargebee/etc., web + iOS/Android, and whether the referral happens before or after account creation, I can map out the exact tracking architecture and compare FirstPromoter vs Rewardful vs Tolt for it.

Rewardful is the other one I'd seriously consider

If you're using Stripe, Rewardful is very compelling. It automatically tracks recurring commissions, upgrades, downgrades and cancellations from Stripe, and supports both no-code and custom-code integrations.

So I'd narrow it down to:

For a Series A B2B SaaS with an internal partnerships team, I’d shortlist:

• PartnerStack — strongest fit if you want affiliates plus referrals, resellers, and co-selling. It supports recurring/expansion commissions, automated payouts, CRM integrations, and a large B2B partner network. PartnerStack PartnerStack
• Impact.com — consider if you expect a broader ecosystem spanning affiliates, creators, referrals, and other partnership types; it supports recurring commissions. impact.com Impact Help Center
• Everflow — good when sophisticated attribution and performance analytics matter most; it tracks subscriptions, repeat customers, and upsells. Everflow Everflow

My practical recommendation: start with PartnerStack. For a Series A team that already has dedicated partnerships personnel, its B2B SaaS orientation and recurring-revenue commission model are particularly aligned with the operating model. PartnerStack

If your program is purely affiliate-focused rather than a broader partner ecosystem, I’d also evaluate Rewardful before committing to an enterprise platform.

For a Series A SaaS company with an internal partnerships team and a recurring revenue affiliate model, I would generally narrow the shortlist to platforms that understand subscription attribution, renewals, expansions, churn, partner lifecycle management, and B2B partner motions—not just click-to-sale affiliate tracking. PartnerStack

My recommendations:

My likely recommendation by Series A scenario

1. You have a real partnerships team (1–5 people) and want to build a channel

Choose PartnerStack.

Typical use cases:

• SaaS affiliates
• agency/channel partners
• referral partners
• technology integrations
• co-selling motions
• recurring revenue share agreements

This is the closest match to “we have a partnerships function, not just an affiliate widget.” PartnerStack

2. You mainly want influencers, creators, affiliates, and paid-performance partners

Choose Impact.com or Everflow.

Good fit if your program looks like:

• hundreds/thousands of partners
• multiple attribution models
• heavy reporting requirements
• global payouts
• marketing operations ownership

3. You are early in affiliate revenue validation

Choose Rewardful or FirstPromoter.

Good fit if:

• you have <100 active affiliates
• Stripe is your source of truth
• you do not yet need partner marketplaces or complex partner workflows

Evaluation criteria I would prioritize for recurring SaaS revenue

Before selecting, verify these capabilities:

1. Subscription lifecycle tracking

• upgrades
• downgrades
• cancellations
• refunds
• expansion revenue
• Commission flexibility

• recurring % revenue share
• first-year-only commissions
• lifetime commissions
• tiered partner rates
• bonuses/spiffs
• CRM integration

• Salesforce/HubSpot attribution
• opportunity-stage commissions
• partner-sourced pipeline reporting
• Partner operations

• onboarding workflows
• enablement materials
• partner tiers
• MDF/co-marketing support
• Finance workflow

• tax forms
• international payouts
• audit trails

Shortlist I would take into a Series A vendor evaluation

1. PartnerStack — if partnerships is a strategic growth channel
2. Impact.com — if you expect enterprise-scale complexity
3. Rewardful — if you need speed and SaaS-native recurring commissions
4. Everflow — if performance marketing analytics is the priority
5. FirstPromoter — if you want a simpler SaaS affiliate engine

For most Series A B2B SaaS companies with an actual partnerships team, I would start with PartnerStack vs. Rewardful as the first comparison: PartnerStack if you are building an ecosystem; Rewardful if you are primarily launching an affiliate channel. Rewardful PartnerStack

A more precise recommendation would depend on your ARR, billing system (Stripe/Paddle/Chargebee/etc.), partner types (affiliates vs agencies vs resellers), and expected number of active partners.

For a B2B SaaS with long trials, sales-assisted conversion, and multi-step funnels, I would prioritize platforms that can attribute beyond the initial click and tie commissions to actual billing events (activation, first payment, renewals, upgrades, churn). A lot of traditional affiliate software breaks when the customer journey is:

affiliate click → free trial → product-qualified lead → demo → contract → annual subscription → expansion

The strongest fits are usually:

My practical shortlist:

If you are <$5–10M ARR and mostly self-serve SaaS

Pick FirstPromoter or Rewardful.

• Stripe + trials + monthly subscriptions: Rewardful is often enough.
• Complex plans, upgrades, multiple billing events, Chargebee/Paddle/Recurly: FirstPromoter is usually the safer choice. FirstPromoter

If your funnel includes sales reps, demos, and partner influence

Pick PartnerStack.

Example:

• Affiliate sends CTO a review article
• CTO starts trial 45 days later
• Sales closes a $30k ARR deal
• Partner gets credit for sourced/influenced revenue

That is closer to a partner management problem than a classic affiliate problem. PartnerStack explicitly focuses on tracking SaaS outcomes and recurring revenue rather than just clicks. PartnerStack

The attribution features I would not compromise on

For your use case, verify that the platform supports:

• Server-side conversion tracking (not only cookies)
• First-touch + last-touch attribution options
• Coupon/code attribution for podcasts, communities, newsletters
• CRM syncing (Salesforce/HubSpot/etc.)
• Trial-to-paid attribution
• Commission holds until payment clears
• Refund/churn clawbacks
• Expansion revenue rules
• Partner-specific commission rules

A common SaaS mistake is paying an affiliate when someone starts a free trial, then discovering months later that:

• the trial never activated,
• sales closed the account independently,
• the customer churned before paying,
• the affiliate deserves credit for influence but not ownership.

For a founder building a serious B2B SaaS channel, I would generally start with:

1. FirstPromoter → if you need reliable subscription attribution without enterprise overhead.
2. PartnerStack → if affiliates are becoming a real partner/channel motion.
3. Rewardful → if you have a simpler Stripe subscription funnel and want speed.

The deciding question is: does an affiliate get paid for generating a signup, a qualified opportunity, a closed deal, or recurring revenue? The answer usually determines the right platform.

The deciding question is: does an affiliate get paid for generating a signup, a qualified opportunity, a closed deal, or recurring revenue? The answer usually determines the right platform.

For an EU-facing SaaS affiliate program, I’d shortlist PartnerStack, Rewardful, and FirstPromoter. “GDPR-compliant” ultimately depends on how you configure tracking, consent, retention, contracts, and international transfers—not merely whether the vendor says it supports GDPR.

PartnerStack explicitly supports recurring commissions tied to subscriptions, renewals, and expansion revenue. Its documentation also describes GDPR/UK GDPR processing, SCCs for international transfers, encryption, access controls, and deletion/access mechanisms. PartnerStack PartnerStack PartnerStack

Rewardful is particularly interesting if you use Stripe. Its tracking connects referral-cookie information with Stripe customer records, and its trust documentation says it operates as both a controller and processor depending on the processing. It offers a DPA on request and documents technical/organizational measures and subprocessors. Rewardful

FirstPromoter supports recurring commissions triggered by billing events and integrates with Stripe, Paddle, Chargebee, Recurly and Braintree. FirstPromoter FirstPromoter

What I'd verify before signing

For EU customers, don't stop at the marketing-page “GDPR compliant” claim. Ask each vendor specifically about:

• DPA: Can you sign a GDPR Article 28 DPA?
• International transfers: Where are customer, affiliate, and end-user data stored/processed? Are SCCs and a transfer-impact assessment available?
• Cookie consent: Can affiliate attribution operate only after the appropriate consent, or can you use privacy-preserving server-side attribution?
• Data minimization: Can you avoid sending unnecessary customer PII to the affiliate platform?
• Deletion: Can you delete/anonymize an individual referred customer's data while retaining the accounting records legally required for commissions?
• Retention: Can retention periods be configured?
• Subprocessors: Is there a current subprocessors list and notification mechanism?
• Affiliate visibility: What customer information is exposed to affiliates? Ideally, affiliates should see commission/reporting data rather than identifiable end-customer data.
• EU payout/tax requirements: How are affiliate identity, VAT/tax information, and payout records handled?

If your architecture is Stripe + EU customers + recurring revenue, Rewardful and FirstPromoter are worth examining alongside PartnerStack. If you expect a more complex B2B partner/reseller ecosystem, PartnerStack has substantially more partner-management functionality. These are capability differences, not an overall ranking. FirstPromoter PartnerStack

If you tell me your billing stack (Stripe/Paddle/Chargebee/etc.), approximate affiliate count, and whether you need cookie-free/server-side tracking, I can make a GDPR-focused feature matrix including DPA, SCCs, EU data residency, consent handling, recurring commissions, payout/tax handling, and pricing.

What I'd verify before signing

For EU customers, don't stop at the marketing-page “GDPR compliant” claim. Ask each vendor specifically about:

For a global SaaS with partners across multiple countries, I’d focus less on basic affiliate tracking and more on recurring commission accounting + international payouts + tax compliance.

Based on current 2026 capabilities, the strongest shortlist is:

The two I'd investigate first

1. PartnerStack — probably the closest match to your requirements.

PartnerStack explicitly supports recurring and usage-based commissions, including renewals and expansion revenue. Its platform says it handles global payouts, tax and currency, with payouts in 100+ currencies and built-in tax/VAT compliance. PartnerStack PartnerStack

That's particularly relevant if your "partners" include agencies, resellers, referral partners, and affiliates, rather than just people posting affiliate links.

partnerstack.com

2. FirstPromoter — worth a serious look if you're primarily running a SaaS affiliate/referral program rather than a full PRM.

It supports recurring commissions and billing events, and its payout tooling supports PayPal, Wise and bank transfer, with built-in W-9 and W-8BEN collection and EU invoicing support. FirstPromoter

firstpromoter.com

When I'd consider impact.com

If you're operating at larger scale and need sophisticated cross-border payment infrastructure, impact.com is another strong candidate. Its payment infrastructure handles things such as invoice generation, tax processing, currency conversion and payment distribution. impact.com

impact.com

One important distinction

If by "tax forms" you specifically mean collecting W-9/W-8BEN/W-8BEN-E information from partners and having the platform manage the associated tax workflow, I'd put PartnerStack and FirstPromoter at the top of the evaluation list rather than choosing purely based on affiliate tracking.

If you tell me your billing system (Stripe/Paddle/Chargebee/etc.), approximate number of partners, and whether they're individuals vs companies, I can narrow this to 2–3 options and compare actual payout fees, FX fees, tax-form coverage, and recurring commission mechanics.

For a global SaaS with recurring subscriptions and partners in multiple countries, I’d narrow the field to PartnerStack, impact.com, and Rewardful. The right choice depends heavily on whether you want an enterprise partner ecosystem or a simpler Stripe-native affiliate program.

1. PartnerStack

PartnerStack is probably the first one I'd investigate for your use case.

It is specifically designed around SaaS economics: recurring commissions can follow subscriptions, renewals and expansion revenue, rather than treating every referral as a one-time conversion. It also supports global payouts, with the company advertising 100+ currencies and built-in tax/VAT handling. PartnerStack PartnerStack

Its tax workflow supports W-8/W-9 collection, while payout providers such as Stripe/PayPal can handle applicable tax reporting. PartnerStack Support

One nuance: PartnerStack says vendors can pay commissions in USD or EUR, while partners can withdraw in supported local currencies. PartnerStack

I'd look at PartnerStack if: you expect affiliates to evolve into agencies, resellers, referral partners, or other partner types.

2. impact.com

impact.com is particularly interesting if "global" means a lot of countries and currencies, rather than simply having some international affiliates.

It has electronic tax-document collection, including W-9, W-8BEN and W-8BEN-E workflows, and supports international tax information such as VAT/GST details. help.impact.com help.impact.com

Its payout infrastructure also supports numerous currencies and bank/PayPal withdrawal options. help.impact.com help.impact.com

I'd look at impact.com if: international payments/compliance and potentially multiple partnership channels are as important as the SaaS recurring-commission functionality.

3. Rewardful

Rewardful is worth serious consideration if you're running Stripe.

It is built around SaaS subscriptions and can handle recurring affiliate commissions. Its managed-payout offering handles tax documents and KYC, with affiliates able to withdraw through bank transfer, SEPA, wire, PayPal, etc. rewardful.com

The tradeoff is that it's more of a focused affiliate-management product than a large partner ecosystem/PRM.

I'd look at Rewardful if: you want to launch quickly, have Stripe at the center of billing, and don't need a sophisticated reseller/co-sell partner infrastructure.

My practical shortlist

For your requirements, I'd evaluate them in this order:

• PartnerStack — if you're building a serious global B2B SaaS partner ecosystem.
• impact.com — if geographic/currency/tax complexity is unusually high or you may run several partnership types.
• Rewardful — if you're primarily running a Stripe-based affiliate program and want substantially less operational complexity.

One important distinction: "tax forms" can mean collecting W-8/W-9 forms, generating 1099s, or actually handling international withholding/VAT/GST obligations. Those aren't the same thing. Before signing, I'd specifically ask each vendor to demonstrate the complete workflow for a hypothetical partner in the US, UK, EU, Canada, and Australia, including onboarding, recurring commission accrual, currency conversion, payout, and year-end tax reporting.

If you tell me your billing stack (Stripe/Paddle/Chargebee/etc.), approximate number of affiliates, and countries you expect to pay, I can narrow this to the most suitable 2–3 and compare pricing/fees and implementation effort.

Its tax workflow supports W-8/W-9 collection, while payout providers such as Stripe/PayPal can handle applicable tax reporting. PartnerStack Support

One nuance: PartnerStack says vendors can pay commissions in USD or EUR, while partners can withdraw in supported local currencies. PartnerStack

I'd look at PartnerStack if: you expect affiliates to evolve into agencies, resellers, referral partners, or other partner types.

Its payout infrastructure also supports numerous currencies and bank/PayPal withdrawal options. help.impact.com help.impact.com

I'd look at impact.com if: international payments/compliance and potentially multiple partnership channels are as important as the SaaS recurring-commission functionality.

3. Rewardful

Rewardful is worth serious consideration if you're running Stripe.

It is built around SaaS subscriptions and can handle recurring affiliate commissions. Its managed-payout offering handles tax documents and KYC, with affiliates able to withdraw through bank transfer, SEPA, wire, PayPal, etc.

The tradeoff is that it's more of a focused affiliate-management product than a large partner ecosystem/PRM.

I'd look at Rewardful if: you want to launch quickly, have Stripe at the center of billing, and don't need a sophisticated reseller/co-sell partner infrastructure.

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

Strong candidates

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

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

The important distinction for your use case

Suppose you have:

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

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

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

What I'd shortlist

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

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

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

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

Shortlist

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

firstpromoter.com

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

rewardful.com

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

partnerstack.com

The important wrinkle for your model

Suppose your contract is:

$100,000 annual contract value

and you want:

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

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

I'd therefore ask each vendor specifically:

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

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

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

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

If the spreadsheet is mainly breaking down because you have subscription revenue, recurring commissions, cancellations, refunds, upgrades/downgrades, and clawbacks, I’d evaluate SaaS-focused affiliate platforms first rather than generic affiliate tracking tools.

Platforms worth putting on the shortlist

Current 2026 comparisons specifically identify Rewardful, FirstPromoter, Tolt, PartnerStack and impact.com as relevant SaaS options. Affitor Documentation Rewardful

FirstPromoter and Rewardful deserve particular attention for your use case. FirstPromoter says it adjusts commissions based on recurring charges, upgrades, cancellations and refunds, while Rewardful explicitly supports recurring commissions plus upgrades, downgrades, cancellations and refunds. FirstPromoter Rewardful

The evaluation criteria I'd use

Don't just ask vendors whether they support "recurring commissions." Give every vendor the same lifecycle test:

• Customer signs up for a $100/month plan → affiliate earns 20%.
• Customer renews → another $20 commission.
• Customer upgrades to $200/month → next commission becomes $40.
• Customer downgrades to $50/month → next commission becomes $10.
• Customer cancels → future commissions stop.
• Customer gets a refund → previously generated commission is automatically reversed/clawed back.
• Payment fails and later succeeds → commission isn't duplicated.
• Customer churns after 4 months → historical commissions remain intact.
• Customer reactivates six months later → determine whether the original affiliate gets credit again.
• Customer changes affiliate/coupon → determine exactly which affiliate owns subsequent revenue.
• Affiliate's commission rate changes → determine whether it affects existing customers or only new ones.

That test will expose the difference between a platform that merely tracks recurring payments and one that actually maintains a correct commission ledger.

My suggested evaluation

I'd start with FirstPromoter, Rewardful, Tolt, and PartnerStack, then add impact.com if you expect a substantially more complex partner ecosystem. Recent comparisons characterize PartnerStack as oriented toward larger B2B partner programs and impact.com toward broader enterprise partnership use cases. Rewardful

For the migration itself, also ask each vendor to demonstrate historical-data import. You don't want to migrate the spreadsheet and then discover that old referred customers have to be recreated manually. FirstPromoter, for example, says it supports historical import from another platform and migration assistance. FirstPromoter

If you tell me your billing system (Stripe/Chargebee/Paddle/etc.), approximate number of affiliates, monthly referred revenue, and commission model, I can turn this into a more specific vendor comparison matrix + migration requirements checklist.

For a subscription business, I’d put these on the evaluation shortlist:

• FirstPromoter — strong fit if recurring billing accuracy is the priority; it supports recurring commissions and automatic adjustments for upgrades, downgrades, cancellations, and refunds. FirstPromoter FirstPromoter
• Rewardful — SaaS-focused and handles recurring commissions, upgrades, downgrades, cancellations, and refunds. Rewardful
• PartnerStack — worth evaluating if you expect a broader B2B partner ecosystem beyond affiliates. Rewardful
• impact.com — broader enterprise partnership platform, particularly if you need affiliates plus creators/referrals and sophisticated partner management. impact.com
• Everflow — consider if performance marketing, multiple acquisition channels, and sophisticated attribution are more important than billing-native subscription logic. FirstPromoter

For your specific spreadsheet replacement, I’d test FirstPromoter and Rewardful first, then compare PartnerStack/impact.com if your requirements are more enterprise-oriented.

During demos, make them process the same customer through initial sale → renewal → upgrade → downgrade → refund → churn and verify the commission ledger at every step. That will expose gaps much faster than a feature checklist.

For an international expansion with local-currency partner payouts and recurring commission tracking, I’d narrow the field based on whether you are primarily a SaaS/subscription company, an ecommerce brand, or a marketplace/large partner ecosystem.

Shortlist

My recommendation by scenario

If you are a SaaS/subscription company

Look first at:

1. PartnerStack — if you have a formal partner/channel motion (agencies, consultants, resellers).
2. Rekomi — if you want subscription-aware commissions (trials, upgrades, churn, recurring rev share) plus payout handling. Rekomi
3. Rewardful or FirstPromoter — if you need something lighter and your stack is already Stripe-centric.

If you expect thousands of affiliates across many countries

Look at:

• impact.com
• Everflow
• TUNE

These are better suited to complex attribution, fraud controls, multiple partner types, and integrations.

If payouts are the hardest requirement

Consider pairing your tracking platform with a payout layer. Some payout providers focus specifically on paying partners globally in many currencies and integrating with affiliate platforms. For example, Payouts.com advertises integrations with platforms such as TUNE, Affise, Impact, and Everflow and supports payouts in many currencies. Payouts.com

Requirements I would insist on before choosing

For your use case, verify that the platform supports:

• Recurring commission rules

• % of subscription revenue
• commission duration (lifetime vs 12 months vs custom)
• upgrades/downgrades
• churn handling
• refunds and chargebacks
• International payouts

• affiliate payout currency vs reporting currency
• local bank rails (not only PayPal)
• FX transparency
• tax form collection (W-8/W-9 where applicable)
• Attribution

• cookie windows
• coupon attribution
• self-referrals prevention
• partner-level reporting
• Finance workflows

• approval queues
• payout exports
• accounting integrations
• audit logs

A practical default choice:

• Early-stage SaaS: Rewardful / FirstPromoter / Rekomi
• Growing SaaS with channel partners: PartnerStack
• Enterprise global affiliate program: impact.com or Everflow

If you share your stack (Stripe/Paddle/Chargebee/etc.), approximate partner count, and whether commissions are lifetime recurring or time-limited, I can narrow this to 2–3 options.

For international expansion with local-currency payouts + recurring commissions, I’d shortlist:

• PartnerStack — strong fit for B2B SaaS; supports recurring/usage commissions and global partner payouts. PartnerStack PartnerStack
• impact.com — broader international coverage, with automated settlement in 70+ currencies and sophisticated payout rules. impact.com
• Rewardful — worth considering if you’re primarily Stripe-based SaaS and want simpler setup. rewardful.com

My practical split: B2B SaaS partner ecosystem → PartnerStack; highly international/multi-channel → impact.com; lean Stripe affiliate program → Rewardful.
