Rejected ACH, PAP, or Direct Debit transactions will always turn into a negative account balance. This is caused by the time frame it takes for MINDBODY to receive rejected responses from the customer’s bank.
When an ACH, PAP, or Direct Debit transaction is run, the software assumes the transaction is successful until the customer's bank has responded otherwise. It can take up to 10 business days after the product or service is sold before the system receives the rejected response. When the system receives the rejected response, the purchases are charged to the client's account because the client could have already started using the services or has received the product.
