I sent the invoice to my client, but it seems I shouldn’t invoiced him this month. I would like to send a credit note where I change the number of services to ‘0’. Unfortunately, I see the error ‘Total value of Invoice/Credit note cannot be zero’.
You misunderstand how credit notes work. You can’t make the invoice zero by adding a zero credit note. You add a credit note that’s the same amount as the invoice. The two will equal zero.
Invoice £10
Credit note - £10
Overall invoice total £0
