Inventory sync & stock management

Better Bundles never duplicates or invents stock. A bundle's available quantity is always computed from the real inventory of its components, so you can't oversell — even when a component is shared across multiple bundles.

How availability is calculated

For each component, the app checks how many bundles the current stock supports (component stock ÷ quantity needed per bundle). The bundle's availability is the minimum across all components. If a bundle needs 2 candles and 1 holder, and you have 10 candles and 3 holders, the bundle shows 3 available.

Automatic sync

Whenever component stock changes — a sale, a restock, a manual adjustment — Shopify notifies Better Bundles and the bundle's available quantity is recalculated automatically. No scheduled jobs, no drift.

Reserve buffer

Each bundle can hold back a reserve buffer: units subtracted from the sellable bundle quantity. If component stock allows 25 bundles and the buffer is 5, Shopify lists 20 available. Use this to protect standalone sales of popular components.

Inventory locations

By default, bundles count stock across the locations configured in Settings → Inventory. Individual bundles can override this and track a custom set of locations — useful if bundles only ship from your main warehouse.

Manual recalculation

You can force a recalculation at any time, in two places:

• From the bundle editor inside Better Bundles.
• Directly on the product or variant page in your Shopify admin — Better Bundles adds a “Recalculate inventory” action and an info block showing the bundle's components.
