This plugin is a a WooCommerce Payment Gateway that specific logged in customers (or all customers) to complete a transaction by paying via Purchase Order and specify a PO or reference number. Once you are ready for the customer to pay, change the order status from “On Hold” to “Pending” and save the order, after making any other changes to the order, such as shipping charges and order total (WooCommerce doesn’t automatically update the Order Total when the order is updated manually), and click “Email Invoice”.
**UPDATE** As of 03/07/2013, WooCommerce Purchase Order Payment Gateway works equally well with WooCommerce 1.6.6 and 2.0.x!!!
The customer will receive an email with a “Pay” link, where they will have the opportunity to pay for the order.
Please note: if you wish to have this behavior customized further, such as setting criteria for when the purchase order gateway is available, please select the “Customized Plugin” and I will contact you for your specifications and send you the updated version via email.
