Everything you'd want to know before you install.
A detailed look at how Smart Bundle Engine for WooCommerce works, why we built it the way we did, and the thinking behind the features above.
The problem
Your customers rarely buy multiple products in the same order, even though strong affinities exist in your catalogue. Classic bundle plugins ask you to guess these affinities by hand — which is slow, biased and rarely up-to-date.
The solution
Smart Bundle Engine analyses the real history of your WooCommerce orders to automatically detect product pairs that get bought together. The engine computes precise statistical metrics (occurrences, confidence, lift) and generates the matching bundles — with no human intervention.
How it works
A daily cron processes your orders in batches of 200 and feeds a co-occurrence table. Once the analysis is complete, the engine selects pairs that pass your thresholds (minimum co-occurrences, minimum confidence) and creates the bundles automatically, respecting a maximum number of bundles per product to avoid over-saturation.
Smart margin control
Each bundle has a minimum margin threshold (configurable). The engine computes the corresponding floor price and automatically caps the requested discount if it would breach that floor. You never sacrifice your margin — the displayed discount is always safe.
Three display contexts
On the product page, the bundle appears right below the product summary with a horizontal layout and a one-click add-to-cart button. In the cart, complementary bundle suggestions appear below the totals table. In the post-purchase email, a next-order suggestion block is inserted with a direct return link to the site.
Discount application
The engine never overwrites your product prices. When all items of a bundle are present in the cart, a global discount is applied via a WooCommerce negative fee. This approach remains compatible with most third-party plugins (taxes, shipping, coupons) and doesn’t disrupt your exports or reports.
Who is it for?
WooCommerce stores with a catalogue of at least a few dozen products and an existing order history. Particularly well-suited to verticals where the average cart contains few items but complementary purchases are possible: cosmetics, fashion, accessories, stationery, food, home equipment.
