A Chargeback Programme That Actually Reduces Losses

Every card brand runs a monitoring programme with a dispute-ratio threshold. Cross it and you enter a remediation programme with monthly fines and mandatory reporting; stay there and acquiring becomes difficult and expensive. Managing disputes is therefore a licence-to-operate issue, not just a P&L line.

Know your ratio, the way your acquirer counts it

Ratios are typically disputes divided by transactions in the same month, but definitions differ by network and some count the prior month's transaction base. Ask your acquirer in writing which formula applies to your MID, and track it weekly rather than discovering a breach on a statement.

The three dispute categories

1. True fraud — stolen credentials. Prevention is authentication, device signals and velocity rules.
2. Friendly fraud — the cardholder recognises nothing on the statement or forgot a renewal. Prevention is descriptor clarity and pre-renewal notice.
3. Service disputes — late delivery, cancellation not honoured, quality complaints. Prevention is refund policy and support responsiveness.

Instrument your dispute data so every case is tagged. Without the split you will spend fraud budget on what is really a billing-communication problem.

Build a repeatable evidence package

Representment succeeds on completeness, not eloquence. A standard package contains: the authorisation record with AVS and CVV results, IP and device fingerprint, proof of delivery or service access logs, the terms accepted at checkout with a timestamp, and any support correspondence. Templating this by dispute reason code raises win rates far more than case-by-case writing.

Prevention that pays for itself

• Billing descriptors that carry a recognisable brand name and a working support number.
• Pre-debit notification for subscriptions, typically 3 to 7 days ahead of renewal.
• Easy cancellation — friction here converts a refund into a dispute plus a fee.
• Alert networks that let you refund before a dispute is filed, at a fee well below the chargeback cost.

Measure what matters

Track cost per dispute (fee + goods + labour), not win rate alone. A 60% win rate on cases that cost more to fight than to refund is a losing programme.
