The bundle uses component stock.

Set inventory on the products and variations inside the bundle. The bundle container has no separate stock quantity. This avoids a second stock count that can drift from your product inventory.

Simple product: Uses the stock settings and quantity of the product.
Variation manages stock: Uses the stock of the selected variation.
Variation shares stock: Uses the stock of the parent variable product.

Example

A workshop kit and a spare marker set

Your Workshop Kit contains 1 notebook and 2 marker sets. You also sell marker sets on their own. A shopper adds 3 kits and 1 extra marker set, so the cart needs 3 notebooks and 7 marker sets.

Stock needed for three Workshop Kits and one separate marker set
Product	In 3 kits	Added separately	Total stock needed
Notebook	1 × 3 = 3	0	3
Marker set	2 × 3 = 6	1	7

The plugin checks this total when the shopper adds a kit to the cart. Checkout checks it again before the order is created.

Backorders follow WooCommerce settings

Your WooCommerce inventory rules stay in control. Set up each product before you add it to a bundle.

Manage stock enabled

WooCommerce uses the stock quantity and the backorder setting of the product or variation.

Manage stock disabled

WooCommerce uses the stock status, such as in stock, out of stock, or on backorder.

Every product must be available

A shopper can buy the kit only when each product in it meets its WooCommerce stock rules. In the example, if only 6 marker sets are available and backorders are not allowed, the cart cannot proceed with that quantity.

WooCommerce inventory settings

WooCommerce documents product stock, backorders, low-stock alerts, and holds for unpaid orders.

Orders, cancellations, and refunds

Each product in the kit has its own order line. The standard WooCommerce stock tools work on these lines.

WooCommerce bundle stock behavior across orders, cancellations, and refunds
Action	What happens to stock
Order placed	WooCommerce reduces stock on each product line, according to your order status flow.
Order cancelled	Confirm that WooCommerce restores the stock of each product once for the status change that your store uses.
Item refunded	Select Restock refunded items when those units should return to inventory, then verify each product quantity.

Payment gateways, order-status automation, and other extensions can change when stock is reduced or restored. Before you go live, place, cancel, and refund a test order on a staging site.

Bundle stock questions

What if the same product appears in two bundles?

The plugin adds the quantity from both bundles to any separate cart line for that product. The cart and checkout check the combined total.

Does the bundle line reduce stock?

No. The bundle has a separate order line that shows the bundle name at a zero price. WooCommerce reduces stock on the product lines.

Can I see how many complete kits I can sell?

Check the stock of each product in the kit. Free does not add a separate report of kit capacity. See what Advanced Bundles Free includes.
