Why it happens
- A payment was submitted twice because of a technical error or a double click.
- A failed payment was retried and both attempts went through.
- Two separate purchases look identical on the statement.
Visa12.6.1Processing error
Duplicate Processing
The cardholder says they were charged more than once for the same purchase.
What to send to fight it
- Proof each charge was a separate purchase, such as two orders, two invoices or two billing periods.
- The transaction records showing distinct dates, amounts or order numbers.
- Proof the duplicate was already refunded or reversed.
How to prevent it
- Use idempotency keys or order IDs so the same payment cannot be sent twice.
- Disable the pay button after the first click.
- Put the order or invoice number on the receipt so customers can tell charges apart.
