Unfortunately, we have the problem of issuing a correct PROJO final invoice that meets tax requirements.
The first page of the final invoice should include the total net sum plus sales tax, total gross amount and the net down payments already made with shown sales tax. The appendix to the final invoice should also be named as a list of previous invoices and payments and the following pages should be numbered consecutively and also shown as an invoice, and the net, sales tax and gross amounts of down payments must also be listed here.
To do this, the placeholders and also the appendix would have to be adjusted accordingly so that there could be no possible double taxation afterwards.
