Why it happens
- The customer paid twice through two different payment methods.
- An invoice was paid by bank transfer and also charged to the card.
- A failed payment was retried after the customer had paid elsewhere.

Paid by Other Means
The card member says they already paid for the same purchase another way, such as another card or cash.
What to send to fight it
- Records showing the other payment was for a different purchase.
- Proof that the other payment failed or was refunded.
- Invoice and account history showing each payment and what it covered.
How to prevent it
- Check for an existing payment before retrying or charging a card.
- Reconcile invoices paid by transfer before the card is charged.
