Create an invoice
Open Sales and create a new invoice.
Select the customer and check the billing address.
Add invoice lines, quantities, prices and a clear description.
Check the revenue account and VAT code on every line.
Keep the invoice as a draft while you still need to edit it.
Finalise
When finalising, Mijn Van Passe checks whether every line is complete. The invoice then receives its final number and the financial lines are locked. Check the customer, date, amounts, VAT and payment term first.
Unable to finalise?
A revenue account or VAT code is usually missing from a line. Open the highlighted line, complete the missing choice and try again.
