    Introduction

    If an invoice from Super Dispatch doesn't sync to QuickBooks Online (QBO) and you see a Duplicate Document Number Error, the invoice ID already exists in your QBO account. To fix it, turn off Custom transaction numbers in QBO, then sync the invoice again.

    What the Error Looks Like

    In Super Dispatch, you'll see a sync error that says the invoice for a load was not synced to QuickBooks, with the reason Duplicate Document Number Error. This happens when the invoice ID Super Dispatch sends is already used by another invoice in QBO.
