Getting started

Pair Pro ships with useful defaults: the block enabled, three products, three columns, in-stock products only, the add-all button on and 150 recent orders analysed. Once the free plugin is active and your store has order history, the block appears without further setup.

Before you start

• WordPress 6.4 or newer
• WooCommerce 8.0 or newer
• PHP 8.1 or newer
• The free Pair plugin, 0.1.0 or newer, installed and active

Pair Pro boots only after the free plugin has loaded. If Pair is missing or inactive, Pair Pro shows an admin notice and does nothing. If Pair is older than 0.1.0, Pair Pro shows a version notice instead of booting.

Install

1. Install WooCommerce and make sure it is active.
2. Install and activate the free Pair plugin (0.1.0 or later).
3. Upload the plogins-pair-pro folder to /wp-content/plugins/, or install the Freemius-provided zip from Plugins → Add New → Upload Plugin.
4. Activate Pair Pro through the Plugins screen and complete the Freemius license activation when prompted.
5. Open WooCommerce → Pair Pro.

Verify the block

Open a product that appears in recent orders together with other products. The Frequently bought together block renders after the product summary, just above the free “You may also like” block, using the theme’s normal product cards.

If the block does not appear:

• The store may have no completed or processing orders that contain this product alongside others. The block hides itself when there is no co-purchase data.
• In stock only is on by default; co-purchased products that are out of stock are filtered out.
• Results are cached for 12 hours per product, so new orders show up after the cache window passes.

Test add all to cart

With Add all to cart enabled (the default), the block ends with a single button. Click it: every purchasable, in-stock product from the block is added to the cart in one request and you are redirected back with the usual WooCommerce added-to-cart message. The button is a plain form post, so it works without JavaScript.

Tune the block

On WooCommerce → Pair Pro:

• Products controls how many co-purchased products to show, from 1 to 6.
• Columns controls the grid, from 1 to 6.
• Orders to analyse controls how many recent paid orders are scanned, from 20 to 1000. Higher values give more signal on large stores at the cost of a heavier scan on cache miss.

Start with the default 3 products. The block sits above the free recommendations, so a small, confident set converts better than a long grid.
