Kitero - Composite Products for WooCommerce

Kitero Product Configurator adds a Composite product type to WooCommerce. You define the choices, called components, and list the products a shopper can pick for each one. The shopper builds their product on the product page and the total updates as they choose.

A gift hamper, a build your own skincare routine, a made to order desk setup and a spare parts kit are all the same idea: a parent product made of choices, priced from what the customer selected. What you can do

• Add as many components as a product needs, with no limits of any kind.
• Assign any number of simple products or variations to each component.
• Search products by name or by SKU, including variation SKUs.
• Show options as a thumbnail grid, larger cards, a radio list or a dropdown. The style is set per component.
• Mark a component required or optional. Optional choices can be cleared by clicking the selected option again.
• Set a minimum and maximum quantity per component, and let the shopper adjust it with plus and minus buttons.
• Set a minimum and maximum number of items for the whole kit, for example a box of six, checked on the product page and again in the cart.
• Change the wording of the Add to cart button and the catalog Configure button.
• Choose between an all visible layout and an accordion layout.
• Show a price range, a starting price, or no price at all in the catalog.
• Add to the cart without a page reload, so mini cart and side cart panels open straight away.
• Five ready made kit templates that build the components in one click: custom PC, gift hamper, meal kit, skincare routine and coffee kit.
• A short setup screen that sets the defaults for every composite product you build.
• Duplicate a composite product and its components come along, ready to edit as a new draft.
• Every choice is written to the cart, the checkout, the order and the confirmation email automatically.
• An Edit link on each kit in the cart reopens the product page with the choices filled in, and Order again rebuilds the kit from a past order.
• Correct tax whichever way your shop enters and shows prices: the kit line is taxed once, with the composite product's own tax class.
• Give the kit its own SKU, stock, Sold individually setting, or mark it Virtual.

Stock is handled properly Stock lives on the products the shopper picks. When an order reduces stock, the stock of each chosen item is reduced by its quantity times the number of kits, and an order note records the change. Cancelling the order puts it back, and so does a refund with Restock refunded items ticked. The cart adds up every kit and every plain product before checkout, in the classic and the block cart, so two kits can never oversell the same item. A kit whose required component has nothing left in stock shows as out of stock. Built in documentation Every option in the plugin is explained inside the dashboard, under Kitero, Documentation. There is no need to leave your site to look up what a setting does. Pro version Kitero Pro is a separate plugin from ProPluginsLab that includes everything in this free plugin and adds:

• Bundle mode: pre-set contents, with optional items the shopper can drop
• Fixed and hybrid pricing strategies, and per option price overrides
• Default choices, several choices in one component, and options taken from categories or tags
• A visual preview that swaps the product image or stacks layer images
• Conditional logic rules between components, enforced in the browser and again on the server
• Two more layouts, a step by step wizard and tabs
• Ten more kit templates, fifteen in total
• Composite insights, a report on the choices customers really make

This free plugin is complete on its own. Nothing here is limited, locked or time restricted, and installing Pro is never required for any feature listed above to work.

1.3.0 - 2026-10-17

• New: an Edit link on each kit in the cart, classic or block based. It opens the product page with the choices filled in, and Update cart replaces the line.
• New: Order again rebuilds each kit from the stored choices, checked against today's products, prices and stock.
• New: composite products get the Inventory tab (SKU, own stock, Sold individually), the tax status and tax class fields and the Virtual box.
• New: a kit without its own weight ships at the combined weight of the chosen items.
• New: the lowest price is stored with the product, so sorting by price and the price filter work for composites.
• Fix: prices are no longer taxed twice, or left untaxed, when the shop enters prices without tax and shows them with tax, or the other way round. The kit line is taxed once with the composite product's tax class, and the product page shows the same amounts as the cart.
• Fix: component stock is checked against the cart quantity of the kit and against every other line in the cart, including a cart quantity change.
• Fix: Restock refunded items now puts the components of a refunded kit back in stock. A later cancellation only returns what is still out.
• Fix: a composite whose required component has nothing in stock shows as out of stock instead of offering a form that cannot be sent.
• Fix: a published composite that cannot be bought says so on the product page.
• Fix: guests on cached pages no longer see "Your session expired" when adding to the cart. Signed in customers still need a valid nonce, and every choice is still checked on the server.
• Fix: the configuration form now works wherever WooCommerce prints the add to cart area, such as the [product_page] shortcode or a page builder template, not only on the product page.
• Improved: saving a product updates its option rows in place instead of deleting and adding them again.
• Improved: option prices on the product page show the component discount, with the original price struck through.
• Improved: new hooks for add ons: kitero_cp_component_saved, kitero_cp_component_product_fields, kitero_cp_catalog_price, kitero_cp_is_in_stock, kitero_cp_before_components, kitero_cp_template_response, kitero_cp_display_fields, kitero_cp_dashboard_actions, kitero_cp_setup_settings and kitero_cp_cart_item_editable.
• Tested with WordPress 7.1.3 and WooCommerce 11.2.1.

1.2.0 - 2026-10-15

• New: duplicating a composite product (Duplicate on the Products list, or Copy to a new draft) now copies its components and their products to the new draft. Developers can hook kitero_cp_product_duplicated.
• Security hardening: a composite can only reach the cart with a validated configuration, including through add to cart links, the Store API and order again; cart prices are recalculated on the server on every pass.
• Security hardening: the upgrade note is shown only to users who can manage plugins.
• The free plugin no longer switches itself off when the Pro edition is active. It stays idle and shows a notice on the Plugins screen so you can deactivate it yourself.
• Uninstalling the free plugin keeps the shared data while the Pro edition is installed.
• Readme: External services section.
• Tested with WordPress 7.1.3 and WooCommerce 11.2.1.

1.1.0 - 2026-09-22

• New: minimum and maximum items for the whole kit, on the Composite display tab. The product page shows the limit and a running count, and the cart checks it again.
• New: set your own Add to cart and catalog button text under Kitero, Settings. Empty keeps the current wording.
• Links moved to propluginslab.io.
• Added Pro upgrade banner on plugin screens.
• Tested with WordPress 7.1.1 and WooCommerce 11.1.1.

1.0.0 - 2026-08-27

• First release.
