Key points

What you see in the shop

Shoppers see nothing new, only correct stock. The Products tab shows linked products, SKU, stock and sync state.

What the admin gets

The first comparison with Square changes nothing: you see the result and choose the stock source.

How much it costs

The base version is free. Pro costs 990 UAH for a one-year licence. A year of updates, technical support and all Pro features.

The trial starts when you ask

A fresh install is the free version, nothing switches on by itself. The “Try Pro for 7 days” button → e-mail → the key right in the window and by e-mail.

One key — a site and a staging copy

Moving the site? Unlink the licence on the old domain and activate it on the new one yourself. A staging copy (staging., dev.) works with the same key and does not take a site slot. For studios — keys for 5 or 25 sites, or unlimited.

Technical requirements

  • WordPress 6.2+, WooCommerce 8.0+, PHP 7.4+.
  • A Square account with an application and a Production token.
  • SKUs on products and variations.

Full module description

Square Two-way Sync keeps WooCommerce and Square stock equal: a sale in one place lowers stock in the other. This is not a payment module: it adds no Square payment option.

This plugin has never worked with real Square. The same author wrote that server, so it carries any misreading of the documents. Start on a copy of your shop.

What you see in the shop

Shoppers see nothing new, only correct stock. The Products tab shows linked products, SKU, stock and sync state. Any link can be removed.

What the admin gets

The first comparison with Square changes nothing: you see the result and choose the stock source. After that changes go through a queue with retries, and once a day the plugin runs a full check.

In Pro you set which field comes from where, and conflicts land on a review list.

How it works, step by step

  1. You paste a Square token and pick a location.
  2. You run the SKU comparison.
  3. You choose the starting source: Square, the shop or neither.
  4. Stock changes go both ways through webhooks and a queue.
  5. A daily check finds differences.

Under the hood

  • Shop sales reach Square as stock adjustments, not sales, unless pushing orders is on.
  • Pushing orders to Square costs 1% at their rate.
  • Pushed orders are plain lines: tax and shipping show separately.
  • The copy-of-site guard stops a staging site from changing your live Square.

How to install

  1. Plugins → Add New → Upload Plugin: pick the zip and activate.
  2. WooCommerce → Square Sync: create an application in Square Developer and paste the token.
  3. Pick a location and set up the webhook.
  4. On the Products tab press Compare with Square.
  5. For Pro: paste the key or start the 7-day trial.

The module is not on wordpress.org yet: the free version and Pro are one archive from this page. Without a key it works as the free version.
