On WooCommerce, the official Product Bundles extension ($79 a year as of October 2026) handles most bundle types. On Shopify, the free Shopify Bundles app covers fixed bundles and multipacks; mix-and-match bundles need a third-party app or a custom build. Choose a custom bundle plugin when you need special pricing rules, stock logic, or the same bundles across both platforms.
Product bundles are one of the simplest ways to raise average order value: customers buy more in one go, and you move slower products alongside popular ones. The catch is that “bundle” means different things, and each platform handles them differently.
This guide explains the main bundle types, what WooCommerce and Shopify offer out of the box, and when a custom bundle plugin is worth it. Upstack Web has built bundle plugins for both WordPress and Shopify, so we know where the standard tools stop.
Common product bundle types
How do you create product bundles in WooCommerce?
WooCommerce’s official Product Bundles extension costs $79 a year (October 2026). It lets you group products into bundles with custom pricing and shipping options, including optional items and quantity rules. For most stores selling fixed or configurable bundles, it is a solid starting point.
How do you create product bundles in Shopify?
Shopify’s own Shopify Bundles app is free and supports fixed bundles and multipacks. It does not offer mix-and-match bundles, where customers choose items from a larger set. For that, stores use third-party apps or a custom app built with Shopify Functions.
Bundle options compared (October 2026)
| WooCommerce Product Bundles | Shopify Bundles app | Custom bundle plugin | |
|---|---|---|---|
| Cost | $79 per year | Free | One-time build |
| Fixed bundles & multipacks | Yes | Yes | Yes |
| Mix and match | Configurable bundles | No (third-party app needed) | Yes, any rules |
| Same bundles on both platforms | No | No | Possible |
| Best for | Most WooCommerce stores | Simple Shopify bundles | Unusual pricing or stock rules |
When do you need a custom bundle plugin?
- Special pricing rules: different discounts by customer group, quantity tiers or combinations.
- Stock logic: bundles that draw stock from components, warehouses or made-to-order items.
- Build-your-own kits with step-by-step choices and live price updates.
- Both platforms: the same bundle logic on a WooCommerce site and a Shopify store.
- Integrations: bundles that must sync correctly with an ERP, CRM or fulfilment system.
What makes a bundle sell well?
- Show the saving clearly: “Save $25 compared with buying separately”.
- Bundle items that are genuinely used together.
- Keep choices simple; too many options slow decisions.
- Show bundle images, not just a list of products.
- Check that stock, shipping weights and returns work correctly for bundles.
What should you test before launching bundles?
Test on a staging copy of your store: prices and discounts, tax, shipping, stock deduction, refunds of part of a bundle, and how orders appear in your fulfilment and accounting tools. Most bundle problems show up in refunds and stock, not on the product page.
