When I try to receive payment from a customer using an echeck with Quickbooks Online, the transaction fails immediately with the message "The transaction was declined because the bank account is incorrect, or there is a security concern". It shows up on the Quickbooks Payments transaction report as Status:Declined and Response:Transaction Declined. I know the routing and account numbers are correct because we've processed payments before. I've also tried using a completely different account owned by the same customer and the error is the same. The customer says that his bank never even saw the attempt. Please help!
