Have a BOTH option update inventory

Technical Q&A
1

Hello,

We currently sell our product in two sizes: Small and Large. We’d like to add a “Both” option that allows customers to purchase both sizes together at a discounted price.

Is there a way to set this up as a variant while still tracking the inventory of the Small and Large sizes individually?

Yes, use bundles and make a “Both” as bundle of “Small” and “Large”.

Hi @ScrambledArt

You can easily manage this setup with the Easify Inventory Sync app :blush:
It lets you create a bundle group that links your “Small” and “Large” products under one combined “Both” option.

When a customer chooses “Both,” the app automatically deducts stock from each individual item, so you can still track inventory accurately for both sizes. Super handy if you want to sell bundles or combo options without losing control of stock levels. Here’s how it works:

1. Create your product with 3 variants Small, Large, and Both (with different price)

2. Set Up Bundle Groups: Use the app to create Bundle groups that connect your “Both” option with your single product. Here’s how to set up a bundle group for your product:

  • Master Product: “Both” variant

  • Component Product: “Small” variant with the Quantity per Bundle set to 1

  • Component Product: “Large” variant with the Quantity per Bundle set to 1

3. How It Works:

  • The inventory for your “Both” variant will be automatically calculated based on the “Small” and “Large” inventory

  • When 1 “Both” is purchased, the inventory of Small and Large will be reduced by 1, total is 2. The app will then recalculate the available quantities for your “Both” variant based on the updated single products inventory, ensuring accurate inventory tracking.

This app is straightforward, and I believe it will work well for you. Reach out to Easify if you need any assistance! :blush:

Hi @ScrambledArt,

I understand your requirements. You can try the Profit Bundles & Mystery Boxes app. With this app, you can create variant-level bundles — for example, a bundle titled “Both” where you include the Small and Large variants of the same product. The inventory for the “Both” bundle will be managed automatically by the app based on the current inventory levels of its child items.

The app comes with a great free welcome plan, which allows you to create unlimited bundles and test how the app processes these bundles without any paywall or cost. Once you are convinced, you can then move to a paid plan as needed.
