The Bundles.app integration lets EasyScan display the component products of supported bundles during picking and packing.
Confirm your bundle is configured in Bundles.app.
In EasyScan, open Settings → General → Integrations, enable Bundles.app and save.
Follow any access/setup instructions in Bundles.app itself, then create a new test order containing the bundle.
Check the components shown in the pick/pack workflow and scan the physical products required by that order.
The integration applies to future orders after it is enabled; an older order may not gain component detail retroactively. Review the relevant bundle display options for pick lists, packing slips and labels.
If you prepack bundles and want to scan a single outer barcode, contact support with your bundle app and an example order. Do not assume there is a per-item “disable breakdown” switch. Shopify-native bundle groups and Bundles.app integration are different sources of bundle information; confirm which your store uses before changing settings.
