A chargeback happens when a customer asks their bank to reverse a card payment instead of asking the merchant for a refund. The money goes back to the customer, the merchant pays a fee, and if that sale came from your link, the commission usually disappears too. Too many chargebacks can cost the advertiser its ability to take card payments at all.
A chargeback is a forced reversal of a card transaction initiated by the cardholder’s bank (the issuer) after the cardholder disputes the charge. Common reasons are fraud (the card was used without permission), “friendly fraud” (the cardholder made the purchase but disputes it), non-receipt, and subscriptions or trials the cardholder did not understand would renew. The merchant loses the sale amount and pays a dispute fee whether or not it wins the representment, and the dispute counts against its standing with the card networks.
The card networks monitor merchants with high dispute rates. Visa replaced its Dispute Monitoring and Fraud Monitoring programs with the Visa Acquirer Monitoring Program (VAMP) on April 1, 2025, combining fraud and disputes into a single ratio, with merchant thresholds tightened again in April 2026 in most regions. Mastercard’s Excessive Chargeback Program flags merchants at a chargeback rate of 1.5% with more than 100 chargebacks in a month, with a higher tier at 3% and 300. Merchants in these programs pay fines and, if they cannot fix the problem, can lose card acceptance.
That is why chargebacks reach affiliates. Advertisers on CPS, trial and CC-submit offers hold commissions until the dispute window has largely passed, claw back commissions on disputed sales, and cut sources whose customers dispute more than others. Traffic that produces chargebacks is usually traffic that was misled: hidden recurring charges, prizes presented as guaranteed, claims the product cannot meet, or users who did not realise who they were buying from because the ad imitated another brand.
The levers on the affiliate side are honesty and source control. Clear disclosure of recurring billing before the card is entered (which the FTC’s negative-option rules require for trials), creatives that match the product, no incentive traffic on card offers that forbid it, and per-source monitoring of refund and dispute reports. A source with a dispute rate well above the offer average is the first to pause, because the advertiser’s card-network ratio is what keeps the offer running for everyone.
A trial-to-subscription offer processes 20,000 card transactions a month across all affiliates. Its dispute rate is close to the 1.5% Mastercard ECP line, and the advertiser breaks it down by traffic source.
| Source | Transactions | Chargebacks | Rate |
|---|---|---|---|
| Search and content affiliates | 9,000 | 45 | 0.5% |
| Native advertorial affiliates | 7,000 | 84 | 1.2% |
| One push affiliate with “free iPhone” hooks | 4,000 | 160 | 4.0% |
| Total | 20,000 | 289 | 1.45% |
One source brings a fifth of the volume and more than half of the disputes. Without it the offer runs at 0.8%, comfortably below any monitoring threshold; with it, a slightly worse month crosses the 1.5% line and above 100 chargebacks, putting card acceptance at risk for every affiliate on the offer. The advertiser will claw back that source’s commissions and close it. Numbers are illustrative.

A reversal of a card payment ordered by the cardholder’s bank after the cardholder disputes the charge. The merchant loses the sale and pays a fee, and affiliate commissions on that sale are usually reversed.
Card networks monitor merchants above set thresholds: Mastercard flags 1.5% with more than 100 chargebacks a month, and Visa’s VAMP, in place since April 2025, uses a combined fraud and dispute ratio with tightened thresholds from April 2026. Advertisers usually act on sources long before those levels.
Because the advertiser no longer has the revenue the commission was paid on, and has paid a dispute fee on top. Most programs reverse the commission and may offset it against future earnings.
Disclose recurring charges clearly, keep creatives honest about the product and the prize, avoid incentive traffic on card offers, and monitor dispute rates by source.
