What is the best affiliate software for SaaS in 2026?

Ask a room of bootstrapped founders which affiliate tool to use and Rewardful is the name you hear most. One Indie Hackers commenter put it plainly: most bootstrappers they know recommend Rewardful for SaaS affiliate programs. It connects to Stripe or Paddle, reads your subscriptions, and calculates recurring commission without a developer.

Starter costs $49 a month and covers up to $7,500 in monthly affiliate revenue, with one campaign and two team members. That is the highest cap at the $49 price point in this ranking (FirstPromoter stops at $5,000). Growth at $99 goes to $15,000 and adds a branded portal on your own domain. Enterprise starts at $149. Billed yearly: $490, $990 or $1,490. Affiliates are unlimited and Rewardful takes no transaction fee.

The catch is payouts. Out of the box, you export a CSV and pay affiliates yourself, and reviewers complain about it. Managed Payouts fixes that for 3% of every payout, and one-click PayPal payouts are Enterprise only. On $5,000 of monthly commissions, that 3% is another $150 a month.

Its limit: two seats and one campaign on Starter. The moment you want one program for customers and another for agency partners, you are on the $99 plan. Chargebee is not among its listed integrations, so check before you commit if that is your billing system. Support, on the other hand, gets praise in reviews, including on messy Stripe setups.

Tip: start the 14-day trial and run one real trial subscription through an affiliate link, then upgrade and refund it. You will see right away whether commissions follow plan changes the way you expect.

FirstPromoter has the deepest SaaS feature set in this ranking. It reads five billing systems: Stripe, Paddle, Chargebee, Recurly and Braintree. If you moved to Paddle to hand off sales tax, or you run on Chargebee, it is one of the few tools that tracks upgrades, refunds and cancellations there without workarounds.

Starter is $49 a month for up to $5,000 in monthly affiliate revenue and 1,000 affiliates. Business is $99 for $15,000 and unlimited affiliates. Enterprise is $149 beyond that, adding white label and SSO. Yearly: $490, $990 or $1,490. Every plan includes unlimited team seats, which matters when marketing, finance and support all need a login.

Payouts are broad: PayPal, Wise, Stripe, crypto or bank transfer, in 190 currencies, and FirstPromoter collects W-9 and W-8BEN forms. Business adds one-click PayPal payouts, self-billed invoices for EU VAT, and a dashboard you can embed inside your app so customers track referrals without leaving your product.

Its limit is the automatic upgrade. Cross $5,000 in affiliate revenue one good month and you are moved to Business, $50 more. Reviews also mention a learning curve. On the plus side, support is praised everywhere, with 4.6/5 on G2, and the team answers every review.

Tip: if you already automate your stack, our FirstPromoter Make integration page shows how to push each new affiliate into your CRM.

Tolt costs more upfront than Rewardful or FirstPromoter: $99 a month for Growth. Ignore the $69 figure still floating around some comparison posts; the official page shows $99. What you get for it is what others bill on top. Tolt takes no fee on payouts, and from Growth you can pay through PayPal, Wise, bank or wire.

Growth covers up to $20,000 in monthly partner revenue with 5 programs and a maximum of 5 team members. Pro at $199 goes to $50,000, lifts every limit, adds Stripe Radar fraud checks and removes the Tolt branding from your portal. Yearly billing gives two months free. Stripe, Paddle and Chargebee are all supported.

The most underrated feature for a US company: tax compliance. Tolt collects W-9 and W-8 forms and files 1099s on every plan, not just the expensive one. There is also a 30-day refund window.

Reviews are glowing (5.0/5 on Capterra), but the sample is small and some reviews appear on several country sites. One user found it better value than Rewardful and Tapfiliate. Its limit: $99 is steep for a SaaS starting with three affiliates.

The math that decides it: with a tool charging 3% on payouts, sending $5,000 in commissions costs another $150 a month. Past that volume, payout fees outweigh the difference in subscription price.

Cello does a different job. Rewardful and Tolt are mostly about paying outside affiliates: bloggers, creators, consultants. Cello is built first for referrals by your own users, inside your software. The referral experience lives in your product, and the price follows the revenue referrers bring in. That is the playbook of product-led growth.

User referrals start from $65 a month on Start, up to $10,000 in referred ARR (annual recurring revenue). Grow is $200 up to $50,000, Scale $750 up to $100,000, then Enterprise on quote. No fee is taken on rewards. One reviewer liked exactly that: pricing tied to results.

Cello also sells a partner and affiliate product, with different math: Free at $0 takes 5% of payouts, Plus at $80 and Pro at $280 take 3.5%, Enterprise 2%. Rewards go out through PayPal and Venmo, in multiple currencies. Cello reads Stripe and Chargebee and connects to HubSpot and Salesforce, with mobile SDKs.

Its limits: Paddle is not among its listed integrations, and the pricing page shows discounted amounts, so read the terms carefully; yearly plans lock you in for 12 months. It also needs some code to place the referral experience in your UI, unlike a plain affiliate link. Published reviews are still rare.

Tip: if your customers are teams, put the invite where they already share something (a report, a link, a dashboard). That is where recommendations happen naturally.

Affonso is the budget pick, and the only vendor in this ranking that lists prices in euros (US buyers pay the euro amount). Launch is €15 a month billed yearly, or €19 monthly, for up to $1,000 in monthly partner revenue. Growth is €29 up to $10,000, Elite €79 up to $30,000, and Enterprise starts at €149. At $10,000 in affiliate revenue, you pay €29 where Rewardful asks $99.

The rare part at this price: an affiliate marketplace on every plan. Your program shows up in a directory where affiliates look for software to promote. At Dub or Reditus, that kind of exposure sits on the top tiers.

On billing, Affonso reads Stripe, Paddle Billing, Polar, Creem and Dodo Payments. Chargebee is not listed. Payouts go through PayPal, Wise or bulk bank transfer; managed payouts arrive on Growth, and the vendor notes that fees may apply.

Its limit is paperwork. Partner invoices and W-8/W-9 collection are Elite only, at €79. If you pay US affiliates or your accountant wants an invoice per commission, the entry price no longer holds. The tool is young too: few reviews, and some directories quote a $49 price that does not match the official grid.

Tip: start on Launch at €19 monthly. Switch to yearly only once your first affiliates have brought in their first customers.

Dub is known for short links and click analytics. Dub Partners adds a partner program on top: Dub automates commission payouts worldwide, tax compliance included. For an engineering-led team, the API, SDKs and webhooks are a real plus.

Business costs $81 a month billed yearly (that price includes the 10% annual discount), for partner payouts up to $30,000 a year. Advanced is $270 a month, up to $180,000 a year. Note that these caps are yearly, not monthly like everyone else's. On both plans Dub takes 5% of each payout. Enterprise, on quote, drops that to 3%.

Run the numbers first. At $2,500 in monthly commissions, you hit the Business yearly cap, and the 5% adds $125 a month on top of the plan. At that volume Tolt takes nothing on payouts. The partner network and marketplace are Enterprise only.

Its main limit for a SaaS: the pricing page names neither Stripe, Paddle nor Chargebee. Check in the docs how Dub reads your subscriptions and refunds before migrating an existing program. It is the least SaaS-specific tool here, ranked for its strength on tracking and global payouts.

Tip: if you automate campaigns, our Dub Make integration page shows how to create partner links on the fly.
