When you export to QuickBooks Online and combine multiple invoices together for a customer, you may end up with a QuickBooks-generated error message in red that may or may not make any sense. It is based on a recently introduced message generated by QuickBooks which is displayed depending on your Sales
settings. One version looks like this:
1.
Click the Settings icon in the top-right corner
of your QuickBooks screen
2.
Under Company Settings > Sales > Sales Form
Content, find the checkbox labelled Deposit.
3.
Make sure the Deposit checkbox is checked.
4. Click Save..
