Self-serve Funnel
Intermediate PronunciationEN/ˈsɛlf sɜrv ˈfʌnəl/
A self-serve funnel is the path on which a user goes from first visit to sign-up and payment entirely on their own, with no conversation with a sales team.
The conventional steps are landing-page visit, sign-up, reaching a first meaningful action, then upgrading to a paid plan. The main difference from a traditional sales funnel is duration: a self-serve path often spans days or weeks with several returns, so without an explicitly defined conversion window any report on it is arguable. The common error is reporting a single end-to-end rate from visit to payment; such a number says something is wrong but not where, and the large leak usually sits in a step nobody suspected, such as email confirmation or a business-details form.
FAQ
The window should come from the product's own behaviour, not from a convention. Plot the distribution of the gap between sign-up and payment and see by which day most conversions have happened; that point is the sensible window. Anything shorter discards real conversions, and anything longer makes the report slow to react.
