A chargeback is a forced refund from a bank/credit card provider. It occurs when an account holder decides to formally dispute a charge on their account. Chargebacks occur on less than 1% of all 2Checkout.com transactions. According to credit card association rules, Internet merchants must accept chargebacks as part of the normal risk of doing business on the Internet.
The amount of disputes you experience will vary according to the type of products you sell. Products that will experience a higher degree of chargebacks are intangible and products that appeal to children, teenagers, and single adults. Products that will experience a lower amount of chargebacks are tangible products and products purchased primarily by professionals and families.
