Hello, I just linked up my accounts to allow customers to pay straight from their quickbooks online invoice via credit card or bank transfer.  It worked great with the first customer.  The second customer received an error.  They attempted 4 times and continued to get the error.  I read and understand that the customer may have blockers or catche that needs to be cleared up.  I just want to make sure that my side of the invoice or account set up is not causing the issue.  How do I verify?

As far as the customers side, I simply cannot give technical guidance to every customer that may have an issue so hopefully quickbooks engineering will have a solution for that.
