Invoicing

The concept of 'billing' doesn't apply to Sales in the same way as it does to Orders. Sales simply generate a receipt most of the time, but can be invoiced on request.

If a customer requests an invoice on a Sale, you can 'invoice' it after the fact. This will simply generate an invoice number (Sales have their own invoice numbering sequence distinct from Orders) and you will be able to print out an 'invoice' PDF.

• Customer is required in order for an invoice to be generated

• Invoices are always paid (remember that the concept of 'payment' doesn't apply to Sales - they are always paid)

• It follows that there are no terms nor due dates (because the invoice is always paid)

• You must enter a billing address in order to be able to invoice a Sale

• You can also enter the customer's tax/VAT number, if that is required by your tax authority
