### Chapter 8

# Invoices

Payage can generate HTML or PDF invoices for Payage transactions. PDF invoices provide a much better user experience.

To enable PDF support, you need to install the (free) LADpdf plugin, which installs the free open source DomPdf PHP library. The LADpdf plugin has no active functions and does not need to be enabled or configured, it simply installs the PDF software library. You also need to set "PDF enabled" to yes on the Invoice Options tab of the Payage Configuration page.

Invoices are configured as an HTML formatted page, with variables that mark the position of the various data items from the user's transaction. PDF files are created by converting the HTML to PDF using the DomPdf library, which requires PHP 7.1 and the PHP DOM extension. Most web servers will satisfy these requirements but if yours doesn't, you can still offer the Invoice Request page that creates HTML invoices that the user can save as a PDF using their browser.

With PDF enabled, you can configure Payage to automatically create PDF invoices immediately after every successful transaction. You can also configure Payage to automatically email invoices to buyers. However, these two options only make sense if your system collects all of the required details in advance for every transaction. For systems that don't always collect all the required details, you can configure the Invoice Request menu item that shows a page where the buyer can complete their details and then download their invoice.
