The problem
Most affiliate tools track a sale, not a subscription
They read the first invoice and stop. Everything that happens next to that customer is invisible to them.
Connects to
Affiliate software for SaaS has to track a subscription, not a sale. Referly connects to Stripe, Paddle, Chargebee or Polar and recalculates commission on every renewal, upgrade, downgrade and refund, so a partner is paid on revenue you actually kept.

How it works
Set the rule once. Stripe does the rest.
One commission plan, applied to every payment a subscription ever makes.

Attribution
How a click becomes a tracked subscription
Four hops. The domain changes at the second one, which is where most tools lose the sale.
01The click
A partner's link lands on your marketing site. The tracker records the affiliate.
yoursite.com/?ref=maya
02The domain hop
They cross to your app. Cross-domain tracking carries the attribution over.
app.yoursite.com
03The checkout
Your server attaches the affiliate id to the Stripe Checkout Session.
client_reference_id
04The webhook
Stripe fires, and Referly records every payment that subscription makes.
checkout.session.completed

The difference
Four things that happen to every subscription
And what each kind of tool does about them.


A generic affiliate toolA customer upgrades in month four
- Recalculated on the new amount
- Still paying the original rate
- Found in the quarterly review
A customer refunds
- Reversed automatically
- Manual clawback, if noticed
- Never reconciled
Your site and app are on different domains
- Carried across (from business)
- Cookie lost at the hop
- Not tracked at all

When a simpler tool is the better buy
Selling a one-time licence that never renews? None of this earns its keep, and a link-only tool at a lower entry price will track that sale perfectly well. Referly is worth paying for when the second payment matters as much as the first.
Run your own numbers
What one customer is worth to a partner
The gap between the two figures is why partners take a recurring program seriously and ignore a one-payment one.
Your numbers
About 24 months of payments, capped at the 24-month window modelled here
Step the rate down after 12 payments
Halves the rate from payment 13. Available from Business.
Model refunds
Reverses the commission on 5% of payments, the way a refund does.
Commission earned with Referly
$1,322
24 payments at 20%, less $70 reversed on refunds.
With a first-invoice-only tool
$58
One payment, one commission. The renewals are invisible to it.
Over one customer's life, the difference is $1,264 of commission your partner either earns or doesn't. Multiply it by the number of customers they send you. That is the whole argument for tracking the subscription instead of the sale.

FAQ
Questions SaaS founders ask
Unsure whether your billing setup fits? A 20-minute call answers it faster than this page can.
It stops with the payments. Commission is calculated per payment, so when the subscription ends there are no further payments and no further commission. Anything already earned and past its holding period still pays out. You are not clawing back a partner's history, you are just not paying for revenue that no longer arrives.
