Set up your bundles

If you sell products that are made up of other products you stock, you can set them up as bundles in Sumtracker. A bundle is a finished product whose available inventory is calculated automatically from its components.

For example, if you sell a gift box containing a bottle, a cap, and a label, you don't need to manually count how many gift boxes you have in stock. Sumtracker looks at the inventory of each component and works out how many complete gift boxes can be built from what's on hand. As components sell or get restocked, the bundle's stock level updates on its own.

Common cases where bundles are useful:

• Gift sets, multi-packs, and combo products
• Print-on-demand or customised products (e.g. a printed t-shirt that draws stock from a plain t-shirt)
• Products shipped with packaging materials you also want to track (boxes, inserts, labels)
• Two listings that should always share the same stock

Creating a Bundle

The bundle SKU must already exist in your Shopify store and be synced to Sumtracker before you can set it up.

1. Go to Bundles Inventory > Create Bundle and choose the product you want to convert into a bundle.
2. Add each component SKU and set the quantity required per bundle.
3. Save.

Once saved, the bundle's stock level is recalculated immediately and synced to your store.

Importing Bundles in Bulk

If you have a lot of bundles, you can import them from a CSV instead of adding each one through the UI.

Go to Bundles Inventory and click Import Bundles and follow the guided steps.

Do I still need my existing bundles app?

This is one of the most common questions we get during onboarding. The short answer: it depends on what kind of bundles you sell.

If you sell fixed, pre-configured bundles → use Sumtracker

If your bundles are pre-defined (the components are decided by you, not the customer), Sumtracker handles them fully. You can stop using apps like Bundles.app, Shopify Bundles, or any other bundling app.

In this case:

• Set Sumtracker as the inventory master for your store.
• Migrate all your bundles into Sumtracker using the UI or CSV import described above.
• Sumtracker will calculate bundle availability from components and push the right stock levels to Shopify.

If you sell customer-customisable or mix-and-match bundles → it depends

Sumtracker is designed for fixed bundles where the components are set at configuration time. For "pick any 3 from 9 variants" style bundles, Sumtracker only works if the customer's individual selections come through as separate line items on the Shopify order.

• If your bundles app puts each chosen variant on the order as its own line item: Sumtracker can handle this without any bundle setup. Each variant's inventory is deducted directly when the order syncs.
• If your bundles app puts only the parent bundle SKU on the order (and not the individual components): Sumtracker can't see which components were chosen and won't deduct the right stock. In this case, you'll need to keep using your existing app for those bundles, or change its settings so that components appear on the order.

If you're unsure how your current app behaves, check a recent bundle order in Shopify and see whether the individual components appear as line items. If they do, you're good to go with Sumtracker.
