One plugin instead of three, and your customer configures every unit.
On woocommerce.com, bundling is three separate paid extensions: Product Bundles, Mix and Match and Composite Products, $317 a year together. BundleBoss does all three jobs in one plugin, with a real free version, and it lets shoppers set the size, colour and options of every unit, for $99 a year.

Each unit gets its own size, colour and options, add-ons included. Team kit, gift boxes and size-run orders finally work the way customers expect.
Free to start, correct to the penny
Build a real bundle free, and every price and fee is added through WooCommerce’s own tax so the total is the same on the page, in the cart and on the order.

Common questions.
Is BundleBoss a free alternative to WooCommerce Product Bundles?
Yes. BundleBoss has a genuinely complete free version on WordPress.org that builds a configurable bundle your customers assemble and buy as one order. Woo Product Bundles is a paid extension, and mix-and-match and composite products are two more paid extensions on top. BundleBoss does all three jobs in one plugin: fixed bundles are free, and build-a-box and customer-picked kits are in Pro.
What can BundleBoss do that the official bundle extensions cannot?
Let a customer configure every unit, options included. In a BundleBoss bundle a shopper sets the size, colour and options of each unit, so ten team T-shirts each come in their own size, or a gift box has every item chosen independently, and buys the lot as one order. Product Bundles asks for one variation per bundled item, and Mix and Match lets a shopper take variations by quantity; BundleBoss also carries options and add-ons on each unit.
Will it charge the right tax and avoid overselling?
Yes. Prices and fees are added through WooCommerce’s own pricing and tax, correct whether your prices are entered inclusive or exclusive of VAT, and component stock is validated while configuring and at checkout so a bundle cannot sell what you do not have.
Does BundleBoss work with WooCommerce Subscriptions?
Not yet. Product Bundles and Mix and Match list WooCommerce Subscriptions among the extensions they work with. If a bundle sold on subscription is what you need, tell us: we build from what shop owners ask for.
Bundle the way customers expect.
One plugin, free to start, where every unit is configured and every total is correct. Add AddOnBoss for personalisation and the box builds itself.
