Payment can be voided the same day the transaction was processed. This means the money does not actually come out of the patient's account yet, though there may be a hold on the funds for 1-3 business days depending on the patient's bank.
After midnight (EST), when the transactions are auto-batched, the payment can no longer be voided, however, the refund button will be available and a refund can be processed. For both Void & Refunds, locate the payment on the [Payments Report Generator™] under the [Actions] column and click the [Void] or [Refund] button. Refunds can take up to 3-5 business days depending on the patient's bank.
