fill_invoiceAction

Fills in the job on this free invoice generator: the client, the line items, the dates, the payment terms and the tax. It never sets the sender, the logo or the payment details; the person types those. Returns the invoice with its totals. Nothing is sent anywhere: the person saves the PDF themselves.
