When processing a customer payment with a saved credit card, you may see an "Invalid Amount" error. This error is generated by Floorzap's payment processor (Adyen) and is tied to the specific card on file — not a Floorzap system issue.
Because this error originates with the card issuer, Floorzap cannot resolve it directly.
What Causes This Error
The "Invalid Amount" error means Adyen rejected the transaction at the card level. This can happen due to card restrictions, account-level limits, or other card-specific validation issues. There is no configuration change within Floorzap that will resolve it.
How to Resolve It
Ask the customer to provide a different credit card, add it to the invoice, and process the payment again. In most cases, using a different card will complete the payment successfully.
When to Contact Support
If the error persists across multiple cards, contact Floorzap Support with the following:
Invoice number
Last four digits of the affected card
Approximate date and time of the failed payment attempt
