Hello @Wolf

According to the QuickBooks API documentation, the DocNumber (Invoice Number) will be automatically incremented if no value is provided. You can refer to the official documentation for confirmation: QuickBooks API - Create an Invoice.

If the auto-increment isn’t working as expected, we recommend reaching out to QuickBooks support for assistance. They’ll be able to help you resolve the issue. Let us know if you need further help!
