Affonso is cheaper at entry, PromoteKit gives more on the paid tier. Both are young indie products, so try the free tiers and pick on feel.
Choose Affonso if

Small Stripe-billed SaaS and AI companies launching their first affiliate program on a tight budget, particularly solo founders and small teams who want a branded portal on their own domain and recurring commission tracking without paying $49 to $89 a month for it.

| Setup time | Under an hour in the straightforward case: connect the payment processor, add tracking, set one commission rule, publish the portal. The vendor's fifteen-minute claim is plausible because there is deliberately less to configure than in a more complex platform. | An hour or two. Connect Stripe, add the script, choose the integration path that matches your checkout, create a campaign, and publish the signup page. The no-code path is genuinely no-code for products on Stripe Payment Links. |
| Learning curve | Low. The product is opinionated and small enough that a non-technical founder can configure a working program without documentation, which is precisely the audience it targets. | Low. The concepts map directly onto how a founder already thinks about a referral arrangement, and the product deliberately does not expose the multi-level complexity that makes older tools hard to learn. |

Strengths and limitations
Affonso
Strengths
- Lowest entry price in the category by a wide margin, at roughly a third of Rewardful's and a fifth of Tolt's, with zero transaction fees on every plan.
- The cheapest plan is not a demo: coupon-code tracking, affiliate groups, custom commission rules, and fraud detection are all included at the entry tier.
- Consent-resilient tracking with documented Cookiebot and OneTrust compatibility, a real advantage for European-facing SaaS that most Stripe-native competitors handle badly.
- The broadest coverage of modern merchant-of-record processors: Paddle, Polar, Creem, and Dodo Payments alongside Stripe.
Limitations
- Solo-founded, bootstrapped, and about two years old; the vendor risk is real for software that holds the record of who is owed what, and there is no acquirer or holding company behind it.
- The Launch tier's $1,000 monthly affiliate-revenue cap is the tightest in the category, so the headline price applies to a smaller set of programs than it first appears.
- Tax form collection is an Elite-plan feature at roughly $99, later than Tolt or FirstPromoter place it, so US companies paying many individual affiliates pay more than the entry price to stay compliant.
- Cookie or attribution window length is not published on public pages, an odd omission for a product that markets its tracking as a differentiator.
PromoteKit
Strengths
- $29 a month flat for unlimited referrals, unlimited campaigns, API, and webhooks, which is the best feature-per-dollar figure in this category.
- No transaction fee and no percentage of affiliate revenue on any plan, including the free tier.
- A custom-domain branded affiliate portal with vendor branding removable, at a price where competitors reserve custom domains for higher tiers.
- Code, low-code, and no-code setup paths, so products built on Stripe Payment Links or no-code site builders are covered without engineering work.
Limitations
- Stripe only. There is no Paddle, Chargebee, Recurly, Shopify, or WooCommerce path, so the tool is unusable outside a single billing system.
- The Enterprise gate at roughly $10,000 of monthly affiliate revenue means the flat-rate advantage has a ceiling, and a successful program will hit it.
- A solo-founder product launched in late 2023, so operating history is short and the concentration risk is real for software that decides who gets paid.
- No multi-level or sub-affiliate structures, no split commissions, and no matrix schemes.
Pricing compared
Affonso
Flat monthly subscription banded on monthly revenue from affiliates, with zero transaction fees on every plan; managed payouts, team seats, branding removal, and annual discovery credits are the features that scale by tier.
- Launch$15
- Growth$39
- Elite$99
- Enterprise$149+
Affonso is the clear price leader and, more unusually, does not achieve that by gutting the cheap tier: coupon tracking, affiliate groups, custom commission rules, and fraud detection are all in the roughly $15 plan, where Tolt charges $69 for a plan without automated payouts and Rewardful charges $49 for a single campaign. The $1,000 monthly revenue cap on Launch is genuinely small, so most working programs will sit on Growth at $39, which is still less than half of what rivals charge for equivalent caps. What you give up for the discount is not features, it is institutional weight: a solo-founded, two-year-old vendor with thin public compliance documentation. For a program under $10,000 a month in affiliate revenue, that trade is usually worth making.
PromoteKit
Flat monthly subscription with a permanently free tier. No transaction fee and no percentage taken from affiliate-driven revenue on any plan.
- Free$0
- Pro$29
- EnterpriseCustom
At $10,000 of monthly affiliate revenue PromoteKit costs $29 a month, or $21.75 on annual billing, which is the cheapest number anywhere in this category for a working Stripe program. That is $310 less per month than Refersion Launch on the same revenue and $200 less than UpPromote Growth. At $100,000 the answer becomes uncomfortable: the vendor directs programs above $10,000 to a quoted Enterprise tier, so there is no published figure and you should assume it stops being the cheap option. That ceiling is the honest limit of the product. Below it, PromoteKit gives you a custom-domain branded portal, recurring and tiered commissions, coupon tracking, self-referral detection, and Wise payouts for less than any competitor charges for a subset of that list, and it takes nothing from your revenue while doing it.
Editorial verdict on each
Affonso
Affonso is the most interesting price in this category, and it earns attention because the discount is not achieved by crippling the cheap plan. Coupon tracking, segmentation, custom commission logic, and fraud detection all ship at roughly $15 a month, the processor coverage reaches the modern merchant-of-record providers nobody else bothers with, and the consent-resilient tracking solves a real European problem. Against that sits a one-person, two-year-old company, no published compliance material, and payout rails limited to bank wire and PayPal. For a program under $10,000 a month in affiliate revenue, that is a sensible trade and Affonso is the smartest first purchase in the category. Past that point, pay more for a vendor with institutional weight.

Best ValuePromoteKit is the correct first purchase for a small Stripe-billed SaaS company that wants an affiliate program and does not want to spend $49 to $89 a month finding out whether it works. Twenty-nine dollars flat buys unlimited referrals, unlimited campaigns, a branded portal on your own domain with the vendor's branding removed, recurring and tiered commissions, coupon attribution, self-referral detection, Wise payouts, an API, and webhooks, with nothing taken from your revenue. The free tier lets you verify all of it before paying. The two things to be honest about are the $10,000 monthly revenue mark where the vendor wants a conversation, which is where the flat-rate advantage ends, and the fact that this is a solo-founder product two and a half years old. Start here, grow into the ceiling, and re-shop the category when you get there.
