Payment methods
Saving cards, setting a default, removing one.
Cards are stored with our payment processor, not in our database. We never see your full card number — only the last 4 digits + brand for display.
Adding a card
/dashboard/profile → Payment Methods → Add card. The card form is a secure iframe direct to the processor — we don't see what you type. Card is verified with a $0 authorization and saved. No charge happens.
Setting a default
Click the star icon next to any saved card. The default is what we charge on renewals when no card is specified for that invoice.
Removing a card
Click the trash icon. If it's the default, set a new default first — otherwise renewals have no fallback.
ACH / bank debits
US-based ACH is supported. Add it the same way; you'll go through standard bank-account verification.
PayPal
Currently manual — you can pay any invoice via PayPal from the invoice page, but we don't store PayPal as an auto-charge method. Cards + ACH are the only auto-charge options.
Crypto
We accept BTC / ETH / USDC / USDT manually per invoice. Open the invoice → Pay with crypto → follow the on-screen address + amount. The invoice marks paid once enough confirmations land.
Failed cards on renewal
If the saved card declines on a renewal charge, we email you and retry the next day. After 6 retries, the service suspends.
Common reasons cards fail:
- Expired — update the card in Profile.
- Insufficient funds — add funds or change cards.
- Bank blocked the charge — your bank thinks it's fraud. Call them, approve Suzko, then click Retry on the invoice.
- 3DS challenge — some banks require you to confirm in their app. The invoice will show a "Confirm" button that opens the challenge.
