How to create product bundles in Shopify

Creating product bundles in Shopify is straightforward once you've chosen the right bundle builder app. Here's the general process:

1. Choose your bundle type: Decide whether you want fixed bundles (pre-selected products), mix-and-match bundles (customers choose), volume discounts (quantity-based pricing), or custom bundle builders (fully flexible selection).

2. Install a bundle builder app: While Shopify offers a native Bundles app, third-party apps like Instant, Amplify, or Bundler provide more customization and advanced features. Install your chosen app from the Shopify App Store.

3. Select products for your bundle: Choose products that complement each other or are frequently purchased together. Consider margin, inventory levels, and customer preferences when building your bundles.

4. Set uour discount strategy: Determine how much discount to offer, typically 10-25% off individual product prices. You can use percentage discounts, fixed amounts, or tiered pricing based on quantity.

5. Design the bundle experience: Customize how bundles appear on your store. With apps like Instant, you can create dedicated landing pages. With widget-based apps, you'll configure how bundles display on product pages.

6. Test and optimize: Launch your bundles and monitor performance. Use A/B testing features (available in Instant, Kaching, and Wide Bundles) to identify which bundle configurations drive the most revenue.

Can you create bundles on Shopify without an app?

Yes, but with significant limitations. You can manually create bundle products in Shopify by:

Creating a new product: Set up a product that represents the bundle with a combined price.

Managing inventory manually: Track individual component inventory separately, which requires manual updates to prevent overselling.

Using discount codes: Apply discount codes at checkout rather than showing bundled pricing on product pages.

Limitations of manual bundles:

• No automatic inventory synchronization

• No variant options for individual bundle components

• Cannot show savings or create urgency

• Time-consuming to manage at scale

• No analytics on bundle performance

• Poor customer experience compared to dedicated bundle builders

For any serious bundle strategy, a dedicated bundle builder app is essential. Even Shopify's free Bundles app provides better functionality than manual bundle creation.
