Depending on your merchant account profile, our payment processor may withdraw funds from your bank account for a few reasons.
1. To satisfy refund requests made in-app.
If you refund some invoice(s) on TUIO, and your payment processor backend account is at 0 balance or lacks sufficient funds to process all refunds, the processor may overdraft your bank account to cover the amount needed for all the refunds and process them for you.
If you have a positive balance in your account at the time of refund, there may be sufficient funds to process the refund without needing to draw funds from your bank account. If you plan on doing a large portion of refunds, it is best to check your account statement on the payment processor backend for the given payment methods you are refunding.
If the account statement shows 0 balance, reach out to support and we can put a hold on payouts while funds accumulate so you can have enough balance to cover the amount of refunds you need to make. When the refund process is finished, payouts can resume.
Note that this is not an automatic process; it is at the payment processor's discretion whether your account is enabled for overdraft in these refund situations.
2. Payment has been returned (Failed) in late stages and funds need to be replaced.
If a payment has been processed and the funds have been deposited into your account, but the payment later fails due to NSF or a similar issue, the payment processor will need to withdraw funds from your bank account to recover the amount and restore your payment processor backend account to a zero balance. For instance, if a payment of $700 was processed and then failed, the Account Statement will reflect a $-700 entry.
Your bank account will be debited $700 to return the account to a zero balance. This is a zero-sum transaction since the funds were initially deposited and then removed. Once the payment is successfully processed, the $700 will be restored to your bank account.
