Why Visa 12.5 chargebacks happen
- Taxes, shipping or fees added after the customer saw the total.
- A price changed between order and charge, or a manual keying mistake.
- Currency conversion made the statement amount look different.
How to prevent them
- Show the full, final total — tax, shipping and fees — before the customer pays.
- Send an itemised receipt with every charge.
- Get the customer’s written approval before charging a changed amount.
