The invoice cannot have a gross value that is zero.
Problem reported by Andy Gambles 6 years ago
It might sound strange but I want to create an invoice in the system which has line items but the total is zero. We do this quite a lot for various reasons.
For example some customers we give a 100% discount but still supply an invoice to show them how much it woudl have cost.
We also have negative line items in some instances for example when using balance from a liability account to pay an invoice. We would add a line to the invoice with description and enter a negative value using a liability account which makes the invoice zero. This liability account may be a customer pre-payment amount.
Can zero value invoices be enabled?
