It’s best to adopt payment processing solutions capable of identifying duplicate transactions. Assigning unique transaction IDs to every payment is essential, and these numbers should be precisely documented on all invoices and receipts.
Once transactions are submitted for processing, review the amounts and timestamps to catch any duplicates, ensuring each charge remains distinct. Should a duplicate charge arise, promptly issue a credit or refund to the cardholder to prevent escalation to a dispute.
Billing descriptors assist customers in recalling details about their purchases, such as what was bought, when, and from whom. Confusing billing descriptors can lead to chargebacks, so employing clear descriptors can reduce disputes caused by customer uncertainty.

Dynamic billing descriptors, which incorporate tailored, transaction-specific details like a store number or product names, are particularly effective in this regard.
Customer complaints should be addressed swiftly as they appear.
Providing refunds, adjustments, or credits promptly can help avoid complaints developing into chargebacks. Clearly communicate refund timelines to customers. To enhance transparency and maintain documentation (useful if chargebacks occur), issue receipts and order confirmation emails following every transaction.
