You can create WooCommerce product bundles using inventory you already sell, without buying extra units or creating duplicate stock records. The key is shared component stock: the bundle pulls its contents from your existing products.
That gives you another way to sell the same catalog while keeping inventory manageable. We recommend starting with one useful combination, then setting its pricing, availability, and checkout rules before publishing.
Key Takeaways
- Build product bundles around existing products so individual and bundled sales draw from the same inventory.
- Choose a fixed price for a set offer, or calculate the total from selected bundle items.
- Track component quantities first; enable separate bundle inventory only when you need an additional sales limit.
- Test variations, discounts, shipping, and inventory reduction together before promoting your offer.
Choose WooCommerce Product Bundles That Fit the Purchase
Product bundles bring related items into one offer. They simplify the purchase and give customers a reason to add more.
A fixed kit works when the contents belong together. Optional products let customers add extras, while composite products suit configurable purchases with dependencies, such as a computer whose parts must work together.
Mix and match suits bulk selections with minimum and maximum limits. A six-bottle craft beer crate is a clear example: customers choose the contents within the permitted quantity.
Frequently bought together recommendations and cross-selling suggest related products and may increase average order value. They don't guarantee a larger or more profitable order.
Use frequently bought together recommendations when shoppers benefit from relevant add-ons. Track clicks and average order value to assess results.
If you only need recommendations, start with our built-in cart cross-sell setup. This type of cross-selling works without a bundle extension. Use a bundle extension when an offer, including one with composite products, needs its own price, required contents, or selection rules.
Pick a Plugin Around Your Catalog
Choose a plugin that fits your product types, variation needs, and purchase rules. A long feature list won't help if bundled products or inventory settings don't work as expected.
These options address different needs:
| Plugin | Best fit | Free or paid |
|---|---|---|
| WooCommerce Product Bundles | Curated kits, optional items, component pricing | $79 for a one-year plan |
| WPC Product Bundles | Straightforward bundles with drag-and-drop setup | Free version; premium features available |
| YITH WooCommerce Product Bundles | Optional contents and purchase rules | Free and premium editions |
| WooCommerce Composite Products | Configurable products with dependencies | Paid |
For a simple catalog, a free plugin can be enough. WPC's premium edition adds variable products, which matters if customers choose sizes or colors.
YITH's bundle documentation covers its configuration options. YITH allows variable products, but customers choose each variation through a dropdown. External or affiliate products can't be included.
The official Product Bundles documentation lists a baseline of WooCommerce 8.2+, WordPress 6.2+, and PHP 7.4+. Release-specific requirements can be higher.
Choose premium functionality when it meets a defined need, such as variation restrictions, flexible quantities, or more detailed shipping control.
Create a Bundle With the Official Extension
Back up your store and use staging for setup when available. Then install and activate WooCommerce Product Bundles.
The official Store Owner's Guide uses this workflow:
- Open Products > Add New Product. Add a clear name, description, and image that shows the actual contents.
- In the Product data dropdown, select Product Bundle. This creates a bundle offer that uses its component products rather than copying them.
- Open Bundled Products. Search your catalog and add existing bundled products. The extension supports simple products, variable products, and supported subscription products.
- Set each bundle item's quantity, optional status, variation restrictions, and individual pricing. Every included product needs a saved price, even when you charge through the bundle's total.
- Configure the bundle's price, fulfillment, inventory, and presentation. Save it as a draft, preview the purchase flow, then publish after testing.
Give the description a clear job: tell customers what arrives. Include required contents, optional extras, quantity limits, and any variation choices.
Set Required and Optional Items
Optional items display a checkbox so customers can include or skip them. Keep essential components required.
Set minimum, default, and maximum quantities for each item. Use bundle-level quantity limits when the total selection must stay within a range.
Keep Variation Choices Clear
Restrict variations when only certain options belong in the offer. Otherwise, shoppers may face unnecessary choices or incompatible combinations.
Inventory is controlled by the product or variation that manages it. A parent product's availability doesn't tell you whether every size or color is available.
Set Pricing Without Giving Away Your Margin
Two pricing models cover most bundles. Plugin labels differ, but the decision is straightforward: should selections change the total?
Auto Calculate for Flexible Contents
Auto Calculate (Sum of Items) adds up selected item prices. It suits optional extras and bundles with changing quantities.
In the official extension, enable Priced Individually for the relevant components. Leave the bundle base price empty when the total should come entirely from those items.
With auto calculate, component price changes stay connected to the bundle total.
Fixed Price for a Clear Offer
Set one total price for the entire bundle. Use this option when the contents are predictable and the offer needs a simple advertised price.
In the official extension, enter the bundle price under General and disable individual pricing for items covered by that total. Individually priced extras can still add charges.
A bundle discount commonly falls between 15% and 30%, but that range isn't a margin rule. Depending on the plugin, discounts can be percentages or fixed amounts applied to regular or sale prices.
We recommend calculating product costs, payment fees, packaging, and fulfillment costs before choosing a discount. Test coupons too, so stacked offers don't erase your profit.
Keep Inventory Shared and Availability Accurate
Let Components Control Available Inventory
Enable stock management under WooCommerce > Settings > Products > Inventory. Then enable tracking for each component product or inventory-managed variation and enter accurate quantities.
When someone buys a bundle, WooCommerce deducts the purchased quantities from the existing component products or variations. The available stock for each component decreases by the quantity included in the bundle.
For WooCommerce product bundles assembled from existing inventory, you usually don't need a separate bundle quantity. Use one only for an additional limit, such as available packaging or assembly capacity.
A separate bundle stock limit adds another sales limit. It doesn't replace the inventory records for the products inside.
Decide What Happens When Something Sells Out
Bundle builders may offer Strict, Flexible, and Ignore modes. Strict hides an unavailable bundle. Flexible disables or hides unavailable items. Ignore bypasses the builder's availability restriction and needs careful use.
These labels aren't universal across plugins. The official extension bases availability on bundle contents and their purchase requirements.
To control catalog visibility, choose Hide unavailable items from the catalog in WooCommerce's Inventory settings. Our out-of-stock visibility guide covers that separate control.
Hiding an item doesn't delete it or change purchasing rules. Backorders can still permit purchases when the quantity is zero. Enabling tracking now won't reconstruct earlier sales, so reconcile existing inventory first.
Make the Product Page, Cart, and Shipping Clear
A bundle's layout can be a list, grid, or accordion, depending on your plugin. Lists suit detailed options, grids emphasize product images, and accordions organize longer selections.
Use a clear layout and keep the total close to the selection controls. Customers can see how each added item changes the price. On mobile, check that the layout keeps choices and prices easy to scan.
Some builders offer Cart Display Mode: Show Only Bundle. This compact option keeps the cart focused on the grouped offer, as long as the included contents stay clear. Other settings show the bundle and its items as separate cart entries.
The official extension uses parent and child cart lines, with grouping controls rather than identical display labels. WooCommerce's bundle-builder configuration guide describes another implementation with different controls.
Shipping can be calculated for one assembled bundle or per item, depending on the plugin. Match the setting to fulfillment, then use the corresponding weights and dimensions.
Test the Whole Purchase Before Launch
A saved product isn't a finished checkout test. Open a private browser window and buy the bundle through your payment gateway's test mode.
Start with the required contents. Add optional items, change quantities, and choose variations. Confirm the price updates with each selection and doesn't add unexpected charges.
Before purchase, record each component's inventory and any separately managed bundle limit. After checkout, compare the figures. Each component's stock should drop by the purchased quantity. Any separately managed stock limit should drop too.
Next, make a required component unavailable. Test optional inventory shortages separately. Confirm the bundle follows your availability rules and backorder policy without allowing overselling.
Review shipping, tax, discounts, coupons, order emails, and the mobile layout. Cancel a test order and confirm each inventory quantity is restored.
If the editor shows fresh inventory but the storefront shows an older figure, investigate caching before changing quantities. Keep the cart, Checkout, and My Account outside shared full-page caching.
Frequently Asked Questions
Can a Grouped Product Replace a Bundle Plugin?
A core WooCommerce grouped product presents related products for individual purchase. It doesn't provide the same bundle-level pricing and purchase rules as product bundles managed by an extension. Use it for a simple collection; choose a bundle extension for a defined package.
Can Bundles Include Subscription Products?
The official Product Bundles extension supports simple and variable subscription products with the required subscription functionality installed. Subscription components must be Priced Individually to create subscriptions. Otherwise, the bundled subscription product is treated as a one-time purchase.
Can Backorders Keep a Bundle Available?
Yes, if the required component's backorder settings and the bundle rules permit it. Core WooCommerce doesn't provide a maximum-backorders field. Our WooCommerce backorder guidance explains how to keep commitments aligned with incoming supply.
Do Bundles Need Extra Physical Inventory?
No. A bundle can sell existing component inventory. You only need extra units if demand requires them, not because you've created another way to purchase the same products.
Build One Clear Offer, Then Grow
Start with one combination customers understand. Shared stock, sensible pricing, and a tested checkout give that offer a dependable foundation.
