Scenario:
After the initial setup of the QuickBooks integration with Web TimeSheet, on generating a client invoice, we may encounter the following error message. This message occurs towards the end of the data transfer.
ERROR: An error has occurred. Detailed information has been logged.

When we try to create a client invoice manually in QuickBooks, the system will prompt us to setup the payment information.

Resolution:
In order to generate client invoice we need to setup the payment details in QuickBooks, post which QuickBooks will save client invoices generated manually or through the integration manager.
