When the case arises that you need to force an invoice and/or a payment to QuickBooks Online, you can do this from the Job details page.
To force this action, navigate to the Job details page for the invoice, and scroll to the bottom to view the QuickBooks Online section of the details page.
Select the three vertical dots in the upper right corner to bring up the menu for the QuickBooks Online box.
Select 'Push invoice/payment to QBO'
This will tell the system to force the information to QuickBooks Online. If you receive any errors doing this action, the box will reload and list the errors under the 'QBO Errors' section. If your attempts to reprocess the error fail, please open the blue chat bubble and allow us to help you further with the error.
PRO NOTE: This action will now allow you to push a $0.00 invoice to QuickBooks Online, but you must have at least one line item on the invoice, that can be $0.00.
