Pay commission when a trial starts
Trials (Pay Per Trial) pays a fixed amount when a referred customer starts a trial, even if they never convert. Percentage is disabled — there is no sale amount when the trial starts. A later paid sale can still pay the group's sale incentive. The two do not replace each other.
Open Incentives Setup
Open Groups, click the group, then Incentives Setup. Click Add Incentive.
Choose Trials (Pay Per Trial)
On Apply to, select Trials (Pay Per Trial). Click Continue.

A group can have only one trial incentive.
Create a Fixed amount
On Select or Create an Incentive, click Create New Incentive.
Percentage, Credits, and Months are disabled. Dynamic Rate is not shown. Set Fixed and the amount per trial. Approval Type can be Immediate, Hold Period, or Manual Review.
Click Create Incentive, then Add Incentive.
Confirm trial tracking
The wizard shows whether trial starts are tracked automatically:
| Provider | Automatic trial tracking |
|---|---|
| Stripe | Yes |
| Paddle | Yes |
| Creem | Yes |
| Polar | No |
| Dodo Payments | No |
If Stripe, Paddle, or Creem is connected, trial starts create the commission from the provider webhook.
If none of those are connected, send a trial-start event through the Events API (event_type: "trial"). Polar and Dodo do not auto-track trials.
Cancelled trials are not clawed back. The trial commission stays. Duplicate trial events on the same referral create only one trial commission.
Common issues
Cannot choose Percentage
Cause: There is no sale amount when the trial starts.
Solution: Use Fixed.
No trial commission on Polar or Dodo
Cause: Those providers do not send a trial-start into Affonso automatically.
Solution: Keep the incentive, and send event_type: "trial" through the Events API.
Affiliate was paid for the trial and the first invoice
Cause: Trial and sale incentives are independent matches.
Solution: Expected. Remove the trial incentive if only the sale should pay.
