Payment is handled by Stripe, and you are sent back to the app afterwards. Which screen you land on depends on what you bought.

Payment Successful! — "Thank you for your purchase. We're processing your order…"
Go to Project takes you to the session you just paid for, where the next step is waiting.
Buying an edit-credit package lands on a verification screen instead. It shows Verifying payment…, then Payment verified! once Stripe confirms, with Go to Dashboard to continue. The credits are on your account as soon as verification completes — see Edit Credits.
Paying through a link sent to you — rather than from inside the app — brings you back through a short sign-in step, which shows Signing you in securely while it works. It is not a confirmation screen, and you normally pass straight through it without reading anything.
If something has gone wrong it says so plainly:
| Message | What it means |
|---|---|
| This checkout link is no longer valid. Please log in. | The link has expired. Sign in normally and your purchase will be on the account. |
| We couldn't find your checkout session. | The session could not be matched. Sign in and check your dashboard before paying again. |
| We couldn't complete your sign-in. | Sign-in failed rather than payment. Try signing in from the login page. |
