Pair PRO
Recommendations based on what customers actually buy together
Pair PRO adds a "frequently bought together" block computed from real, paid orders, a one-click button to add the whole set to the cart, a bundle discount, manual curation, category rules, extra placements, an editor block, A/B testing and click analytics.
Extends Pair FREE
Frequently bought together, bundle discount, A/B testing and analytics, all shippedRequires the free Pair pluginDelivered through Freemius
PRO features
Recommendations from real demand instead of categories alone, plus control over what shows where, and the numbers to tell whether it works.
Frequently bought together
A product-page block of the items most often purchased in the same order, mined from completed and processing orders (bounded scan, 12h cache).
Add all to cart
One button adds the whole set to the cart. Plain nonce-protected form, no JavaScript dependency.
Bundle discount
An optional "buy the whole set, save X%": once the set is in the cart the discount applies as a negative cart fee, and it drops off as soon as any product from the set leaves the cart.
Manual curation
Hand-pick the recommendations for a specific product instead of leaving it to the automatic picks. The selection is stored in product meta and leads the automatic results.
Category rules
"When a product is in category A, recommend from category B". Rules are set globally and lead the product-page block.
Extra placements
Recommendations on the order-received page and at checkout too, in the same markup as the free plugin's blocks.
Editor block
A dynamic "Pair Recommendations" block for the block editor and FSE templates, rendered on the server.
A/B testing
Each visitor gets a sticky variant (cookie): A keeps the default strategy, B swaps in another one, and the dashboard reports both side by side.
Recommendation analytics
Impressions, clicks and add-to-cart attributed to the clicked product, on their own screen. Attribution is click-based and approximate, a directional signal rather than revenue accounting.
Performance and HPOS safe
Reads orders through the WooCommerce order API (HPOS-compatible), a bounded scan of recent orders, and a cached result. Settings live on WooCommerce > Pair Pro.
