Make it possible to pay you

Test with a real card, on a real phone, from a real network. Not in test mode.

Objective 1.5

Target: One successful live charge

Inside this

Take one real charge in live mode1h
Charge yourself a dollar. Test mode hides at least one real failure, always.
Complete checkout on a phone20m
Most of your launch-day traffic arrives on mobile, from a link in a feed.
Turn on failed-payment emails30m
Involuntary churn is the cheapest revenue you will ever recover. Switch it on now.
Handle sales tax and VAT1h
Stripe Tax, or a merchant of record. Decide once; retrofitting is genuinely painful.
State the refund and cancellation policy20m
EU customers can cancel within 14 days by law, so the policy has to say so; for instant access, ask at checkout for their express agreement to give that right up. Our view, not a measured result: a plain, visible policy costs less in refunds than it earns in trust.
