Card payments are handled by Stripe. We never see or store your card number, and a decline comes from your bank rather than from us.
Common causes:
- Billing address does not match the one your bank holds
- Bank blocking an online payment it does not recognise. Approve it in your banking app and try again
- Corporate card blocked for online training. Ask your finance team, or choose invoice instead on orders of 10 or more
- Not enough available balance
If money left your account but you have no confirmation, do not pay again. Send us a message with the date and amount and we will check and either release access or refund.
