If your payment didn't go through, don't worry — here are the most common reasons and how to fix them.
Common reasons
- Insufficient funds — check your bank balance
- Card declined — your bank may be blocking the transaction; call them to authorize it
- Incorrect card details — double-check your card number, expiry, and CVC
- International transaction block — some banks block cross-border transactions by default
Payment plan installment failed
If an automatic installment payment fails, we'll retry automatically. Make sure your card is funded before the retry. If it still does not go through, try another card or contact us for help troubleshooting.
If your bank keeps declining, try a different card or contact your bank to whitelist payments to "Checkmark Tutorials" via Stripe.
