Quick answer

Which SaaS affiliate tool fits you?

For most SaaS companies the shortlist is Rewardful, FirstPromoter, Tolt, Referly, Partnero and Affonso. Rewardful and FirstPromoter start at $49/mo and track Stripe. Referly is $75/mo and tracks Stripe and Shopify. Partnero is the only one that never caps your affiliate revenue. Costs below.

Referly

Referly

You sell on Stripe plus a store, or you need tax forms and your own portal domain.

Rewardful

You are Stripe-only, under $7,500/mo in affiliate revenue, and want $49/mo.

FirstPromoter

You bill through Chargebee, which Rewardful does not support.

Tolt

You want the fastest setup and can live with manual payouts on Basic.

Partnero

Your affiliate revenue is already big. Flat fee, no revenue meter.

Affonso

You are pre-revenue and want the cheapest possible start at €15/mo.

Every tool, every price, every cap

The cap is the column buyers skip and then hit in month four.

Run the numbers

What one customer is worth to a partner

Three commission models on one customer. Move the churn month, it changes more than the rate does.

  1. One-timefirst payment only$19.80
  2. Recurring20% for 18 payments$356.40
  3. Recurring, stepped down20% then 10% after 12$297.00

Commission on one customer over 24 months, stopping at churn. The step-down model is what most SaaS programs actually want: enough to win the partner, not so much that a customer they referred three years ago is still the largest line in your commission bill.

The shortlist

Six tools, six honest limitations

Ours included, at the same weight, with the $26 it costs above Rewardful stated plainly.

Built around commission rules that follow a subscription, not a single payment.

  • Recurring commissions with step-down schedules and caps
  • Refund detection reverses the commission automatically
  • W-9, W-8 and EU invoices handled in the portal

Limitation: $75/mo against Rewardful's and FirstPromoter's $49, and affiliate revenue caps at $10,000/mo on Startup. Automated payouts start on Business at $149.

Best for SaaS that also sells through a store, or needs the tax paperwork done.

Rewardful

The best-known Stripe-first tool and the shortest path to a working program.

  • $49/mo, no transaction fee
  • Stripe Premier Partner
  • Fast setup, huge user base

Limitation: Stripe or Paddle only, by their own FAQ. Add a store and you replace it. Starter caps affiliate revenue at $7,500/mo.

Best for Stripe-only SaaS under $7,500/mo in affiliate revenue.

FirstPromoter

The deepest feature matrix at the $49 tier, with Chargebee support.

  • Chargebee alongside Stripe and Paddle
  • The most configurable campaigns in its class
  • 14-day trial, no card

Limitation: Starter has the tightest cap of the $49 tier: $5,000/mo in affiliate revenue. No transaction fee is stated either way.

Best for Chargebee-billed SaaS that wants maximum configurability.

Tolt

Fast, clean, Stripe-first. Running in an afternoon.

  • Setup measured in minutes
  • A partner portal affiliates like
  • 14-day trial, no card

Limitation: Basic is manual payouts only. Automated payouts carry a 2% processing fee and start on Growth at $99, along with tax forms.

Best for small Stripe-only teams that value speed above all.

Partnero

The only tool here that never meters on affiliate revenue.

  • Flat fee no matter how big the program gets
  • Affiliate, referral and newsletter programs in one
  • 30-day trial, the longest in the category

Limitation: Starter is one program and one seat, and extra seats cost $29/mo each.

Best for programs already large enough that a revenue meter hurts.

Affonso

The cheapest entry in the whole category at €15/mo billed annually.

  • Nothing else is close on price
  • Covers a Stripe program's basics
  • 14-day trial

Limitation: The Launch plan caps affiliate revenue at $1,000/mo and gates custom domains and private programs. Realistic only before the program works.

Best for pre-revenue founders testing whether a program converts.

Before you pick

What breaks in a SaaS affiliate program

Does commission follow the subscription?

Renewals, upgrades, downgrades and churn, not just the first payment.

What happens on a refund?

Automatic reversal plus a holding period, or you email partners for money back.

Where is the revenue cap?

Every tool here except Partnero has a cliff. Know yours before month four.

Who collects the tax forms?

W-9 and W-8 collection built in, or a spreadsheet and a January panic.

Do coupon codes count?

Half of SaaS affiliate sales start as a code in a YouTube description.

What does leaving cost?

No export means re-onboarding every partner. Some will not come back.

One customer on $99.00/mo, 20% commission

Churns in month 7

One-time commission

Paid on the first invoice only

$19.80

Recurring commission

Paid every month until churn

$118.80

123456789101112
Commission paid After churn, nothing to pay and nothing to reverse
Same referral, two commission models, a 6x difference before the customer even churns. Which is why the churn month, not the rate, is the number worth arguing about.

The verdict

Which one should you pick?

Stripe only, under $5,000/mo in affiliate revenue

Rewardful or FirstPromoter

Past $30,000/mo in affiliate revenue

Partnero's flat fee

Referly

Stripe plus a store, or you need tax forms handled

Referly

  • Usually yes. Check the caps, not the features: Affonso caps affiliate revenue at $1,000/mo and Rewardful's Starter at $7,500/mo. Both are fine until the program works, which is exactly when migrating hurts most.
