Chargeback Expertz provides tips to avoid chargebacks for merchants. There are three primary reasons for chargebacks: item not received, significantly not as described, and unauthorized transactions. Good customer service helps avoid chargebacks by providing contact information, order confirmations, quick responses to inquiries, dispute resolution policies, and clear return policies. To prevent disputes from becoming chargebacks, merchants should keep shipping records, purchase insurance, use trackable shipping, communicate about unavailable or damaged items, provide accurate descriptions, and contact customers about potential unauthorized transactions.
