What to notice
Show the end of free use, charging conditions and cancellation before starting a trial.
Where it fits
- Fits
- People considering services with trial conversion or renewal.
- Use it when
- When trial, payment and cancellation behavior can be explained accurately.
- Avoid it when
- When displayed boundaries differ from actual billing.
How to build it
- State the end date, cost and actual charge trigger.
- Expose cancellation routes and deadlines before enrollment.
- Offer optional advance reminders and a trial-state check.
Measure
- Main metric
- Share of eligible trial users making an informed continue-or-end choice
- Guardrail
- Unwanted renewals and failed cancellation attempts
- How to measure
- Allocate comparison groups before exposure and use equal follow-up and eligibility. Track Share of eligible trial users making an informed continue-or-end choice alongside Unwanted renewals and failed cancellation attempts.
When it backfires
Cancellation must remain usable beyond the trial.
