If you received revenue share commission for a sale that is eventually refunded or charged back, the commission that was paid to you will be revoked. When a sale if refunded, the customer receives 100% of the initial payment.

If the seller offers partial refunds, the refunded amount will be in the appropriate ratio, according to the commission rate, from the seller and the affiliate.

The default refund period is 60 days (however it can be between 30 and 364 days, depending on the seller's preferences), ClickBank retains a certain portion of affiliate funds to cover the possibility of returns. This portion is referred to as a “return allowance.”

If you received CPA commission for a sale that is eventually refunded or charged back, the amount you were paid is not returned to the customer. You keep the entire flat rate commission and the seller is responsible for any return costs.
