This means there is not enough available balance on your merchant account to process the refund.
To make sure you always have enough balance for processing refunds, set up a Reserve: In your Customer Area select your merchant account, go to Finance > Balances overview, and select Control your balances.
You have the following options to add funds to your Reserve:
- Increase the Reserve threshold: The amount needed to fill the Reserve will be deducted from the Payable balance.
- Set up auto-funding: We initiate a direct debit payment when the Reserve balance drops below a configured value. The amount needed to fill the Reserve is debited from the bank account where you receive the payouts for this merchant account. You can only use auto-funding for payout bank accounts in EUR, GBP, or USD.
- Transfer funds to our bank account: We add the transferred funds to your Reserve as soon as we receive them. This can take up to four business days.
For an overview of all refunds that were not processed due to
insufficient balance, select Finance > See all charts and exports > All reports > Modifications not Processed report (data is available from March 31 onwards).
Adyen does not automatically retry refund requests that failed due to insufficient in-process funds. When enough funds are available again, you need to resubmit any failed refund request.
