Definition
Trial-to-paid conversion occurs when a user or account that started as a trial begins a paid subscription. In affiliate programs it often marks the first revenue event eligible for commission.
B2B SaaS context
Product-led SaaS teams may receive affiliate traffic weeks before revenue appears. Tracking trial-to-paid conversion lets the program reward partners for actual customers rather than unqualified trials alone.
Operator note
Connect the trial identity to the billing customer and define whether commission triggers on first invoice paid, checkout completion or subscription activation.
