FirstPromoter vs Rewardful vs Tapfiliate vs Affonso (2026)
Affiliate programs look cheap on a slide: pay 20% of revenue you already earned, and let the software handle tracking. Then you read the pricing pages and discover that “from $49/month” is tied to a revenue ceiling that a decent referral program will blow past in its second quarter.
This is a cost breakdown of four tools a solo founder would realistically shortlist in 2026: FirstPromoter, Rewardful, Tapfiliate, and Affonso, with the plan caps, the hidden step-ups, and which one fits which kind of business. All prices were pulled from the vendors’ own pricing pages in November 2026. Where a vendor quotes in euros, I’ve kept the euro figure rather than convert it.
Key Takeaways
- All four charge by affiliate-attributed revenue or by volume, not by seat count, so your bill scales with success, not with headcount.
- Rewardful and FirstPromoter both start at $49/month, but their Starter caps differ: $7,500/month of attributed revenue for Rewardful, $5,000/month for FirstPromoter.
- Tapfiliate is the most expensive at the entry level ($89/month) and the most generous on infrastructure limits, 30+ ecommerce integrations, 5,000 tracked clicks.
- Affonso is dramatically cheaper, at €19/month on monthly billing, but designed for founders who want payouts handled for them.
- The real cost driver is the cap, not the sticker price. Crossing a revenue threshold typically doubles the subscription.

FirstPromoter: the Stripe-native default
FirstPromoter has become the reflexive recommendation for Stripe-based SaaS, and the pricing page explains why: the Starter plan is $49/month (or $490/year, two months free) and explicitly caps at $5,000/month in revenue generated by affiliates, not total company revenue. That distinction matters. If you’re doing $30K MRR and 10% of it is affiliate-driven, you stay on the entry plan.
The Business tier raises the ceiling to $15,000/month in affiliate revenue, and anything above that moves to Enterprise with a “let’s talk” conversation. Starter is capped at 1,000 affiliates, which is not a limit you’ll hit organically.
Integrations are the strongest argument here: Stripe, Paddle, Chargebee, Recurly, and Braintree, plus a historical Stripe import so you don’t start from zero when you migrate. Coupon codes sync into Stripe automatically, and affiliates can create and customize their own. Attribution supports first-click or last-click with a cookie life configurable up to 9,999 days.
Who it fits: a SaaS founder on Stripe who wants referral tracking to feel like a Stripe feature rather than a separate business. If you’re on Paddle or Chargebee, this is close to a default.
Where it strains: the $5,000 Starter cap arrives quickly for anything with a $200+ price point. Ten referrals a month at $500 ACV and you’re bumping the ceiling.
Rewardful: the cheapest path past $5K
Rewardful starts at the same $49/month but gives you a higher Starter ceiling, up to $7,500/month in affiliate-attributed revenue, and charges 0% of that revenue. Growth covers up to $15,000/month and runs $990/year on annual billing (roughly $99/month), and Enterprise starts at $149/month or $1,490/year for up to $30,000/month.
Every tier includes unlimited affiliates, unlimited tracked visitors, REST API access, multi-currency support, first- or last-touch attribution, coupon code tracking, double-sided incentives, and self-referral fraud detection. That’s an unusually flat feature line, the upgrade is mostly about the cap and about branding.
The branding gap is real, though. A branded affiliate portal, custom domain, private invite-only campaigns, and custom reward structures are all Growth-and-above features. On Starter, your affiliates see Rewardful’s UI. If you’re recruiting creators who expect a polished partner experience, budget for Growth from day one rather than discovering it later.
Payouts go out over PayPal mass pay or Wise bulk transfer, and the platform also supports managed payouts if you’d rather not touch the money flow.
Who it fits: a Stripe SaaS whose affiliate revenue is between $5,000 and $7,500/month, where the extra headroom on the entry plan is worth real money. Also a good fit if you want a genuinely 0% transaction fee with no asterisk, Rewardful’s page is explicit that the fee is 0% and the subscription is the only charge.
Where it strains: it’s Stripe-centric. If your billing runs through Chargebee or Recurly, FirstPromoter is the better-integrated option.
Tapfiliate: the ecommerce answer
Tapfiliate charges more and delivers more surface area. Launch is $89/month, or $74/month on annual billing, and includes 50 affiliates, one affiliate program, 5,000 tracked clicks per month, and 500 conversions per month. Scale is $179/month or $149/month annually: 150 affiliates, unlimited programs, 100,000 clicks, 10,000 conversions, multi-level marketing, automated payouts, and deeplinks.
Overage pricing is published rather than hidden, which is rare and useful. On Launch, extra clicks cost $1.50 per 1,000 and extra conversions cost $15 per 1,000. On Scale, those drop to $1 and $10. Enterprise is custom and adds tailored limits, unlimited team members, full white-label, and a dedicated account manager.
The integration list is the differentiator: 30+ pre-built connections including Shopify, WooCommerce, BigCommerce, Magento, and Stripe, plus a JS pixel, REST API, and server-to-server postback integration. If you sell physical goods or run a store alongside a SaaS product, Tapfiliate is the one on this list that was clearly built for that.
Who it fits: ecommerce and hybrid businesses. Also anyone who wants MLM or multi-tier structures, which the other three either don’t offer or bury in an enterprise tier.
Where it strains: $89/month is a lot to pay before you have affiliates. The click and conversion caps are generous for a small program but the tiers are volume-based, so a high-traffic content affiliate can push you up faster than revenue does.
Affonso: the cheap, payout-managed option
Affonso prices in euros and undercuts everyone. Launch is €19/month on monthly billing (€15/month annual) for unlimited affiliates and referrals, up to $1,000/month in partner revenue, with custom commission rules, coupon tracking, affiliate groups, and fraud detection. Growth is €29/month for up to $10,000/month in partner revenue, adds managed payouts (Affonso pays your affiliates for you), private programs, and five team seats. Elite is €79/month for up to $30,000/month, unlimited seats, unlimited affiliate groups, and a dedicated success manager. Enterprise starts at €149/month.
There’s also a 50% startup discount for early-stage companies, which is worth asking about explicitly rather than assuming you don’t qualify.
The $1,000 cap on Launch is the catch. For a founder with a $29/month product, that’s roughly 34 referred customers per month before an upgrade, fine at the start, tight by month six. But the Growth tier at €29 for a $10,000 ceiling is the cheapest per-dollar-of-capacity in this comparison by a wide margin.
Who it fits: the founder who wants affiliate tracking set up in an afternoon, doesn’t want to run payouts themselves, and is price-sensitive to the point of caring about a €10 difference.
Where it strains: it doesn’t bill itself as a Stripe-native tool the way FirstPromoter and Rewardful do, and the feature depth at the top end is thinner, no multi-level marketing, and affiliate recruitment tooling is lighter than PartnerStack’s.
What about PartnerStack?
Worth naming because it comes up in every search. PartnerStack doesn’t publish prices. Its pricing page says the plan is “confirmed during your demo” and is based on program size, feature needs, and support level. That’s a signal: it’s built for partner ecosystems (resellers, co-marketing, channel partners), not for a solo founder paying 20% commissions on a $49 subscription. If you’re evaluating it, expect a sales cycle and a number that starts in the thousands per year.
The cost math that actually decides it
Ignore the sticker price. Model the ceiling.
If you expect affiliate revenue to stay under $1,000/month for the next year, Affonso Launch at €19 is the cheapest correct answer and it’s not close. Between $1,000 and $5,000, Affonso Growth (€29) still beats FirstPromoter’s $49 and Rewardful’s $49 on price, though you’re trading integration depth for euros.
Above $5,000/month, the calculus flips toward the Stripe-native tools, because the cost of a bad attribution setup (mis-tracked conversions, manual reconciliation, affiliates who don’t get paid on time and stop promoting) dwarfs a $50/month difference. Rewardful’s $7,500 Starter ceiling makes it the cheaper choice in the $5,000–$7,500 band specifically.
And if you’re on Shopify or WooCommerce rather than Stripe, none of that math matters. Tapfiliate’s $89 is the price of not duct-taping a SaaS referral tool onto an ecommerce store.
Practical notes before you commit
- Check your billing provider first. FirstPromoter covers Stripe, Paddle, Chargebee, Recurly, and Braintree. Rewardful is Stripe-focused. That single fact eliminates half the shortlist before price enters the conversation.
- Trial all of them. Every tool here offers 14 days. Set up one real affiliate link and one real test conversion in each before you pay, attribution bugs are much cheaper to find in a trial than after a payout dispute.
- Ask about the cap in writing. “Up to $5,000/month” usually means you get a warning, then a forced upgrade, not a hard stop. Confirm what happens at the boundary and whether overage billing exists.
- Budget for the portal. If recruiting creators is part of your plan, the branded portal on Rewardful Growth or Tapfiliate is not cosmetic. Affiliates promote the programs that look legitimate.
Where these numbers come from
Every price above was read off the vendor’s own pricing page in the first week of November 2026, not from a review roundup. For an independent cross-check on plan caps and annual discounts, Referly’s Rewardful pricing breakdown and iTechGuides’ FirstPromoter plan table both track the same figures month to month. Review scores are on G2 if you want to read complaints before committing.
Bottom line
For a Stripe SaaS founder in 2026, the decision usually comes down to two: FirstPromoter if you need Paddle, Chargebee, or Recurly integration, and Rewardful if you’re pure Stripe and want the higher cap at the same price. Choose Tapfiliate the moment ecommerce enters the picture, and Affonso when the budget is genuinely tight and you want payouts handled for you.
None of them will make an affiliate program work. They’ll just stop it from leaking money once it does.
