Total cost, not list price
Platform fee, percent of revenue, payout fees and seat limits are recorded separately, so you can compare what a program really costs.
Documented facts, not a quality ranking. Pricing and rights depend on the selected plan.
| Decision criteria | PromoteKit | Affonso |
|---|---|---|
| Consider for | Stripe-based solo founders and small SaaS teams testing a first affiliate program, particularly those wanting coupon tracking and a real but capped free tier. | Micro SaaS or subscription startups using supported modern billing providers, especially those comparing Paddle Billing or Polar alongside Stripe. |
| Paid entry / monthly | $0/month | $19/month |
| Billing detail | Free plan: $0 with up to three referrals. Pro: $39/month, or $29/month with annual billing; Pro covers up to $10,000 per month of affiliate-attributed revenue. Above that, request an Enterprise quote. | Launch: $19/month month-to-month, or $15/month when billed annually; monthly affiliate-attributed revenue cap is $1,000. |
| Free plan | Yes | No |
| Free plan detail | Free plan is limited to the first three referrals and one affiliate campaign; it is not an unlimited free tier. A 14-day paid-plan trial is also advertised. | No permanent free plan. A 14-day trial is advertised on paid plans. |
| Commissions | Fixed or percentage rewards can run on one-time purchases or qualifying subscription renewals. Paid tiers support product-specific rules and commission tiers; refunds in Stripe adjust commissions. | Supports fixed and percentage commissions, one-time and recurring rewards, partner groups, link and coupon tracking, and configurable commission rules. Payout funds are separate from the tracking integration. |
| Tracking method | Tracks links using a website tracking script, or Stripe promo codes without website script; referral cookies default to 60 days and are configurable. Stripe is required for billing attribution. | Affiliate links, coupon codes, product-aware commission rules, fraud checks and refund handling are documented. The vendor lists native Stripe, Paddle Billing, Polar, Creem and Dodo Payments integrations. |
| Payouts | PayPal and Wise batch exports and manual payouts are offered. Optional one-click Stripe Connect global payouts require a paid plan/trial; current FAQ describes processing fees of 5% for bank funding or 8% for card funding on the payout total. Verify payment coverage and checkout fees before using. | Manual payout exports support PayPal, Wise and bank transfers, with the merchant making the actual payment. Managed payouts require Growth or higher: official help documents a $25 per managed invoice service fee, a possible payment-method surcharge, and $0.50 per affiliate after the first 25. Check current terms and provider fees. |
| Integrations | Requires a Stripe account. Dedicated Webflow app and integrations with Memberstack, Outseta and MemberSpace are documented. Paddle/Chargebee native billing integrations were not confirmed. | Native integrations listed for Stripe, Paddle Billing, Polar.sh, Creem and Dodo Payments. API, webhooks and SDK are documented; test your exact checkout and subscription event flow before switching. |
| API available | Yes | Yes |
| Consider the limitation | Merchants who use Paddle instead of Stripe, need more than three referrals without paying, or exceed Pro's $10,000 monthly affiliate-attributed revenue allowance. | Businesses requiring a no-cost permanent plan, predictable uncapped affiliate-attributed revenue at Launch pricing, or fully managed payouts without extra fees. |
