A plan upgrade survey asks free users what stands between them and a paid plan at the moment they reach its edge. This template asks two questions in under half a minute: what is stopping them from upgrading today, from the price to someone else's approval, and which paid feature would help them most.
It is written for a popup in your web app that opens when a free user hits a plan limit, fired by a custom event in your code (from Starter, or on 1 survey on Free). The same survey goes out by email to free users who reached a limit this month, and a redirect after submit can take every user who answers to your plans page.
Results shows the share of each reason and of each paid feature, with typed Other answers listed, against the period before. Select a reason to see which feature those users want, so you know what to put in front of each group. Add an open question at the end if you want the reasons in users' own words: Usertick reads every written answer and files it under a category such as pricing and plans, with a type and an urgency.
