GazChap039s WooCommerce Purchase Order Payment Gateway for WordPress

The good stuff

What really clicked was how it handles the PO number field. You can require it, and even auto-fill the billing address for logged-in users. That saved me so many times when someone forgot to include their shipping info. I’ve also used the edit feature in the admin panel - you can tweak the PO number or notes directly on the order page. Not a big deal, but super handy when you’re chasing down a missing PO from a client who sent it via email after placing the order.

And the REST API integration? That’s the quiet MVP here. If you’re syncing with an ERP or accounting system, it’s nice that the PO data shows up in the API response. No extra work needed. It doesn’t generate invoices, but it captures all the details you need to make one later. Compared to plugins that overpromise (looking at you, some of those “all-in-one” invoice tools), this one stays focused. It does exactly what it says.

The not-so-good

It’s not going to win any design awards. The interface is… barebones. If you’re used to polished admin screens, this feels like a throwback. And since it’s free and has zero downloads listed, it’s not exactly a community favorite. That means limited support if something breaks - you’re on your own. Also, no way to customize the label beyond “Purchase Order” unless you hack the code. Not a dealbreaker, but worth knowing.

And yeah, it doesn’t generate invoices. If you need that, you’ll still need another plugin. But honestly, that’s fine - this isn’t trying to be everything. It’s just a clean way to collect PO numbers without adding friction.

Bottom line

If you’re a business that takes POs regularly and wants a no-fuss way to capture them in WooCommerce, this plugin is solid. It’s free, it works, and it doesn’t get in your way. Skip it if you need full invoicing or heavy customization. But if you just need to track POs, it’s a reliable, lightweight choice. Definitely worth a download.
