POW – Purchase Orders for WooCommerce

POW – Purchase Orders for WooCommerce adds a configurable purchase order payment method to WooCommerce. It is built for B2B, wholesale, corporate, account-based, and invoice-based stores where customers place an order now and pay later by purchase order or invoice.

Customers can enter a purchase order number and invoice details during checkout. Store owners can enable or disable invoice fields, mark fields as required, create extra custom PO fields, control which customer roles can use the gateway, and choose the WooCommerce order status assigned after checkout. Purchase order details are saved as order meta and displayed on the thank-you page, customer account order page, admin order screen, WooCommerce emails, and compatible PDF invoice plugins.

Purchase Order Payment Gateway

Dedicated WooCommerce payment method – adds a new POW Purchase Order gateway under WooCommerce payment settings.
Flexible checkout text – edit the checkout title, checkout message, confirmation note, and PO number label.
Order status control – choose the order status assigned after a purchase order checkout, such as On hold, Pending payment, Processing, or any custom status registered on the store.
Classic and block checkout support – works with WooCommerce classic checkout and WooCommerce Checkout Block.

Configurable Invoice Fields

Show or hide default invoice fields from the gateway settings.
Mark each visible field as required or optional.

Custom PO Checkout Fields

Create extra purchase order fields without code from WooCommerce > Settings > PO custom fields.
Supports Text, Email, Number, Textarea, and Select fields.

Custom fields are saved to the WooCommerce order using the meta key entered by the store owner.
Saved custom fields can appear in order details, admin order screens, customer account pages, and compatible invoice templates.
