Shopify admin app

Bundle prices that follow their components

Shopify's free Bundles app does not change a bundle's price when a component's price changes. BundleMath does. Keep the free Bundles app. Add automatic price sync.

BundleMath is a Shopify admin app from CNR Consulting Services, Inc. that keeps native Shopify Bundle prices in sync with component product prices. Base is $6/month and Pro is $12/month. Both include a 14-day free trial. Billing is through Shopify.

How a bundle price is calculated
  1. Sum of the component prices
  2. Minus the fixed or percent discount you set, per bundle or store wide
  3. Then a rounding rule, such as .99 or .95

That result is the bundle price.

What it does

When you change a component's price, BundleMath recomputes each parent bundle that uses it. The new bundle price is the sum of its components minus the fixed or percent discount you set, per bundle or store wide. Rounding rules keep endings like .99 or .95.

Base includes auto sync, rounding, and a change log with one-click revert. Pro adds compare-at sync and an audit screen that finds bundles priced off your rules and fixes them all at once.

BundleMath works with Shopify's free native Bundles app. It updates prices only. It does not replace how you build bundles.

How it works

  1. Install BundleMath from the Shopify App Store and connect your store with Shopify OAuth.
  2. Set a store-wide discount and rounding rule, or override them on individual bundles.
  3. Edit a component price in Shopify as you normally would.
  4. BundleMath detects the change, recalculates each parent bundle, and writes the new price.
  5. Check the change log if you need to undo a write. On Pro, run the audit screen when you want a store-wide check.
