Description

This plugin allows you to securely accept payments, synchronize sales, and seamlessly manage inventory and product data between WooCommerce and Square POS.

The Square plugin is PCI and SAQ A-level compliant.

Accept payments anywhere, anytime

The Square plugin extends WooCommerce to allow you to accept payments via Square – including support for Apple Pay®, Google Pay, WooCommerce Subscriptions and WooCommerce Pre-Orders.
Recurring customers can save payment methods and use them at checkout.
Customize payment forms with automatic formatting, mobile-friendly options, and retina card icons.

Manage your business all in one place

Sync your product and inventory information from WooCommerce to Square, or from Square to WooCommerce — set everything up once, and whenever you make a sale, your inventory automatically updates on both platforms.

If you sell mainly online, set WooCommerce as your system of record so WooCommerce pushes product name, inventory, prices, categories, and images to Square.
If you sell in multiple locations and online, set Square as your system of record so Square pushes product name, inventory, prices, categories, and images to WooCommerce.

Installation

You can download an older version of this gateway for older versions of WooCommerce from here.

Automatic installation

Automatic installation is the easiest option as WordPress handles the file transfers itself and you don’t need to leave your web browser. To
automatically install WooCommerce Square, log in to your WordPress dashboard, navigate to the Plugins menu, and click Add New.

In the search field type “WooCommerce Square” and click Search Plugins. Once you’ve found our plugin you can install it by clicking Install Now, as well as view details about it such as the point release, rating, and description.

Manual installation

The manual installation method involves downloading our plugin and uploading it to your web server via your favorite FTP application. The WordPress codex contains instructions on how to do this here.

Updating

Automatic updates should work like a charm; as always though, ensure you backup your site just in case.

Note

If running PHP 8.2+, you may see some deprecation notices being logged. These notices are known and do not impact any plugin functionality.

FAQ

Does this require an SSL certificate?: Yes! An SSL certificate must be installed on your site to use Square.
Where can I find documentation?: For help setting up and configuring the plugin, please refer to our user guide.
Where can I get support or talk to other users?: If you get stuck, you can ask for help in the Plugin Forum.

I’ve found this plugin works well in terms of syncing products and changes to products. I can update SKUs, names, and shipping details in Woo and everything syncs to Square perfectly. My only wish so far is that I could have an option to hide wallet payment buttons on single product pages.

Only use this plugin if you want to use it as a payment gateway and nothing more The sync doesn’t work. The settings section doesn’t even work. The “Hide synced products when not found in Square” will not save. Very frustrating. You’d think an official WooCommerce plugin would be better.

NOTE: this review pertains ONLY to the inventory syncing functionality, NOT the payment processing functionality. Been using the plugin since early 2024 (1+ yr). It reliably syncs 10,000+ inventory items. 100s of features? No. Works as advertised? Yes. I haven’t had a need to contact support, but will update review if/when. Good stuff.

Everything was great until the next day. Twenty hours after installation, the media gallery showed over 700 copies of the wc-square-gift-card-placeholder.png and growing. It was multiplying like bunnies. A support ticket to Automatic got a few responses. Once they mentioned that this was a known bug and they would make a note of it, they stopped answering emails. Upon some digging, this “bug” has been “known” for quite a while. They should pull this plugin off until it is fixed.
