Duplicate Document Number Error: You must specify a different number. This number has already been used

The error message about duplicate numbers occurs because:

1. Vinosmith pushes an invoice to QB but does not receive a response. The invoice might appear in QB, but Vinosmith still considers it pending because QB never confirms receipt.

2. QB has another invoice (not created by Vinosmith) with the same invoice number as the one being pushed.

If the Vinosmith invoice is in QuickBooks, you can manually mark it as exported in Vinosmith to clear it from the Batch Invoice screen.

1. Open the concerned invoice.

2. Click on the More Actions button.

3. Click Export

4. Select Mark as Exported

If there is an invoice with the same number that isn't the Vinosmith invoice, you can either change that invoice's number in QB or update the Vinosmith invoice in Vinosmith with a new one and try submitting the invoice again.
