GazChap's WooCommerce Purchase Order Payment Gateway


This plugin adds a new offline payment gateway to WooCommerce that allows your customers to request an invoice with a Purchase Order.

There are a number of options:

  • You can set the plugin to ask the customer for a Purchase Order Number, and dictate whether this is mandatory or can be left blank.
  • You can set the plugin to ask the customer for a postal address for the invoice.
  • You can set the plugin to pre-fill this address with the customer’s existing billing address (if they are logged in, and have one set in WooCommerce)
  • You can set the plugin to add supplied Purchase Order information to order notification emails

When an order is received, the plugin will add all of the submitted information on to the WooCommerce View Order screen.

Note: This plugin does not (currently, at least) generate the actual invoices – it is only used to collect the Purchase Order information.


WordPress. Tested up to version 5.2.3.
WooCommerce. Tested with versions up to 3.7.1, minimum version is 3.0.0.


Once installed and activated, you need to enable the Payment Gateway in WooCommerce > Settings > Checkout (or via the plugin’s Settings link on the WordPress Plugins page) – you can then set the various options for the plugin at the same time.

We needed the ability to allow customers to use a purchase order as a method of payment, came across GazChap's plugin and it couldn't have fitted our purpose any better. Very simply, it does exactly what you'd expect without drama or fuss. Thanks GazChap - brilliant plugin!
