Root Cause

• Partial refunds already processed: Previous partial refunds have reduced the available amount for further refunds.

• Incorrect refund amount: The requested refund amount is larger than what remains unrefunded.

• Gateway refund restrictions: Some gateways strictly enforce refund limits tied to the original transaction amount.

Troubleshooting and Solutions

• Check the refund history for the charge in Chargebee and at the payment gateway.

• Verify:

  • The amount already refunded from the original transaction.

  • The remaining refundable amount is available.

• Adjust the refund amount to match the available balance.

• Communicate clearly to the customer if only a partial refund can be processed.

• If needed, offer alternative resolutions, such as issuing a credit note or a discount on future purchases.
