Error: This invoice won't be posted to accounting software as there is no Net amount.

When you attempt to publish an invoice, this error will occur if you don't have a net amount: (It will show a triangle in both the Inbox folder and the invoice window).

Publishing requirements:

AutoEntry isn’t able to publish tax-only invoices.

If always need to fill the net and total fields to be able to publish.

If you have a tax only invoice, for example an import tax, you need to enter the invoice directly into your accounting software.
