Free WooCommerce Product Bundles Plugin

What Is a WooCommerce Product Bundle?

Definition

A WooCommerce product bundle is a special product type that groups two or more individual products and sells them together as a single package. Instead of customers adding each product to the cart separately, they add one bundle item and the store automatically handles all the products inside it.

Bundles are different from grouped products. With grouped products, each item is added to the cart individually. With a bundle, all items are linked together — changing the bundle quantity changes every item inside it, and bundled items cannot be removed individually from the cart.

How Product Bundles Work in WooCommerce

When you use a WooCommerce product bundles plugin, it creates a new product type — usually called “Product bundle” — in your product editor. You then search for and add existing simple or variable products to that bundle. Each item gets its own quantity settings, pricing rules, and optional status.

On the front end, customers see the bundle product page with all items listed. If any item is a variable product, customers pick their preferred options (like size or color) right on the bundle page. After clicking Add to Cart, the entire bundle appears as a parent item in the cart, with each bundled product listed underneath it.

Bundle vs. Grouped Product vs. Kit

A grouped product is a collection of standalone products displayed together — each must be added to the cart separately. A product bundle groups items into one unit with a shared price. A kit is essentially the same concept as a bundle; the terms are used interchangeably in most WooCommerce contexts.

Why Sell Product Bundles in WooCommerce?

Increase Average Order Value

Product bundles are one of the most effective ways to increase the average order value in your store. Instead of selling a coffee mug for ₹200, you bundle it with a notebook and a pen, and sell the set for ₹400. The customer perceives higher value; you move more inventory in one transaction.

Move Slow-Moving Inventory

Bundles let you pair popular products with slower-moving items. A customer who was only going to buy your best-selling T-shirt might also pick up a pack of notebooks when they are offered together at a small discount.

Simplify the Shopping Experience

For gift buyers or customers who are unsure what to choose, a pre-packaged bundle removes the decision fatigue. A “Starter Kit” or “Gift Box” bundle gives them a ready-to-go option in a single click.

Offer Discounts Without Devaluing Individual Products

With a WooCommerce product bundles plugin that supports discount pricing, you can offer 10% off when products are bought together — without reducing the regular price of each item individually. This protects your price positioning while still rewarding customers who buy more.

Introducing the QT WooCommerce Product Bundles Plugin

The QT WooCommerce Product Bundles plugin is a free WordPress plugin developed by Quick Tips. Unlike many free bundle plugins that limit variable product support or advanced pricing to paid tiers, QT Product Bundles includes all of those features at no cost.

The plugin was built using Claude AI (developed by Anthropic), which allowed the entire plugin architecture — from the custom product type and cart logic to the admin interface and REST API — to be designed and iterated rapidly with a focus on WooCommerce compatibility and real-world usability.

Who Should Use It?

QT WooCommerce Product Bundles is ideal for:

• WooCommerce store owners who sell gift sets, starter kits, or product kits
• Stores that carry variable products (clothing, accessories) and want to bundle them
• Anyone who wants bundle pricing without paying for a premium plugin
• Developers building custom WooCommerce stores who need REST API access to bundle data

How to Install the QT WooCommerce Product Bundles Plugin

Requirements

• WordPress 6.0 or higher
• WooCommerce 7.0 or higher
• PHP 7.4 or higher

Installation Steps

1. Download the QT WooCommerce Product Bundles plugin zip file.
2. In your WordPress dashboard, go to Plugins > Add New > Upload Plugin.
3. Choose the zip file and click Install Now.
4. Click Activate Plugin.
5. Make sure WooCommerce is already installed and active. The plugin will not activate without it.

After activation, you will find a new “Product bundle” option in the Product data dropdown whenever you create or edit a product.

How to Create Your First WooCommerce Product Bundle

Step 1 — Create a New Product

Go to Products > Add New. Enter a product name such as “Starter Kit”. In the Product data dropdown (below the description area), select Product bundle.

Step 2 — Add Bundled Items

Click the Bundled Items tab in the product data panel. Use the search box to find the products you want to include. Click Add to add each one. You can add multiple simple and variable products.

For each item, set:

• Default quantity — how many the customer gets by default
• Min quantity — the minimum they must order
• Max quantity — the maximum they can order (leave blank for unlimited)
• Optional — tick this if the customer can choose to include or exclude this item

Step 3 — Choose a Pricing Mode

Go to the General tab (or a dedicated Pricing tab if shown). Select your pricing mode from the dropdown. See the next section for a full explanation of each mode.

Step 4 — Choose a Shipping Mode

In the shipping section, choose either “Ship as one package” or “Ship items individually”. If you choose to ship as one package, configure the bundle’s weight and dimensions in the Shipping tab.

Step 5 — Publish

Click Publish. Visit the product page to confirm the bundle form loads, quantities show with +/− buttons, and the total price updates as you change options.

Pricing Modes Explained

Sum of Item Prices

In this mode, the bundle costs whatever its individual items cost. If a mug is ₹200 and a notebook is ₹150, the bundle is ₹350. If an item is on sale, the bundle total reflects the sale price automatically. This mode is ideal when you want completely transparent pricing.

Fixed Bundle Price

You set a specific Regular price (and optionally a Sale price with schedule support). Optional items and quantities above each item’s default quantity are charged on top of the fixed price. For example: a Gift Box is fixed at ₹849 (sale, was ₹900). If the customer adds an extra mug (₹200), the total becomes ₹1,049.

This mode is great for gift sets and curated bundles where you want full price control regardless of which products are inside.

Item Prices Minus Discount

In this mode, you set discounts per item — either as a percentage (e.g., 10% off each mug) or a fixed amount per unit (e.g., ₹50 off each T-shirt). You can also apply a whole-bundle discount on top. The product page shows the original price struck through and the discounted total, making the deal immediately obvious to customers.

This mode works well for volume discounts and bundle deals where you want the savings to be visible.

Variable Products Inside Bundles

One of the biggest limitations of free bundle plugins is their lack of variable product support. The QT WooCommerce Product Bundles plugin handles variable products as a core feature, not an upsell.

How Attribute Selection Works

When you add a variable product to a bundle, a dropdown for each attribute (Size, Color, etc.) appears on the bundle product page. Customers pick their preferred options just as they would on a regular variable product page. The price, image, and stock status update live as they make their selections.

Restricting Allowed Variations

In the bundle admin, you can choose which specific variations are allowed for each item. For example, you might only allow the Large Red and Large Blue options of a T-shirt in a bundle. Any variation you have not allowed will be hidden from the customer.

Locking a Variation

You can also lock a specific variation so the customer cannot change it. This is useful for bundles where you want to control exactly which product variant is included — for example, a bundle that always ships with a Medium White T-shirt, with no customer choice.

Out-of-Stock Handling

If a particular variation is out of stock, that option is disabled in the dropdown and marked with an availability notice. The customer cannot add the bundle to their cart with an out-of-stock variation selected.

Cart, Checkout, and Order Display

Cart Grouping

When a customer adds a bundle to their cart, it appears as a parent row with each bundled product listed underneath. Bundled items are visually indented and labelled as part of the bundle. Customers cannot remove individual items — they can only remove the entire bundle or change the bundle quantity.

Updating Bundle Quantity

Changing the bundle’s quantity in the cart automatically updates all its child items proportionally. Stock is checked for every bundled item when the quantity changes.

Mini-Cart

The mini-cart also shows bundle contents under the bundle parent, so customers see a complete summary without going to the full cart page.

Order Pages and Emails

In the WooCommerce admin order view, bundled items are shown grouped under their parent bundle, clearly labelled as “Part of: [Bundle Name]”. This same grouping appears on the customer’s order page and in order confirmation emails, providing a clean, professional order summary.

“Order Again” Support

When a customer uses the “Order again” feature on a past order that contained bundles, the plugin correctly reconstructs the entire bundle configuration — including selected variations and quantities — in a new cart.

Shortcode, Gutenberg Block, and Elementor Widget

Shortcode

Use the shortcode [qt_product_bundle id=”123″] to display a bundle’s add-to-cart form on any page or post. You can pass extra parameters:

• show_title=”yes” — shows the bundle’s product title
• show_price=”yes” — shows the price range
• show_image=”yes” — shows the featured image
• show_excerpt=”yes” — shows the short description

Gutenberg Block

The “QT Product Bundle” block is available in the WordPress block editor. Search for it in the block inserter, then type or select a product ID. The block renders a fully interactive bundle form wherever you place it — on landing pages, custom layout pages, or anywhere in a block-theme template.

Elementor Widget

If you use Elementor, a dedicated “QT Product Bundle” widget is available in the widget panel. Drag it onto your page, enter the product ID in the widget settings, and the bundle form renders in your Elementor layout. No shortcode required.

Free vs. Paid: Feature Comparison

Here is how the QT WooCommerce Product Bundles plugin compares to typical free plugins and the kinds of features often locked behind paid plans:

As you can see, the QT Product Bundles plugin offers a feature set that usually requires a premium subscription, completely free of charge.
