How do I fix a QuickBooks duplicate invoice number error?

If an invoice cannot sync to QuickBooks because its invoice number is already in use, you can fix the issue directly from the invoice in Titus.

Why an invoice gets stuck

QuickBooks requires invoice numbers to be unique. If you entered an invoice into QuickBooks manually or use your own numbering system, the number Titus assigned may already be in use.

When there is a number conflict, QuickBooks cannot sync the invoice.

How to fix the conflict

1. Open the invoice in Titus and go to the invoice details.
2. Change the invoice number to one that is not already used in QuickBooks.
3. Save the invoice.

Saving the new number automatically retries the QuickBooks sync. You do not need to disconnect and reconnect QuickBooks or wait for a scheduled sync.

You can update the invoice number whether the invoice is unpaid, partially paid, or fully paid.

What happens to payments already recorded

Changing the invoice number does not remove payments from the invoice.

Once the number conflict is resolved and the invoice syncs successfully, card payments, disbursements, and manual payments already recorded on the invoice will sync to QuickBooks as well.

Can I prevent invoice number conflicts?
