ONL077 Export Error in QuickBooks Online

If you see the error:

ONL077: Duplicate Document Number flagged. Please disable the setting in QuickBooks.

This means QuickBooks Online is blocking the export because duplicate document number warnings are enabled.

Why the ONL077 Export Error Happens in QuickBooks Online

The ONL077 error occurs when:

• QuickBooks Online has duplicate bill number warnings turned on.
• The document number being exported from Expensify matches an existing bill number in QuickBooks Online.

When duplicate document number warnings are enabled, QuickBooks Online prevents the export from completing.
