About this Product
Bundles & Kitting Inventory Manager is a Shopify app that lets your brand sell bundles, kits and multipacks without ever overselling the parts inside them. When a customer buys a "Starter Kit" or a "3-pack," the underlying components share inventory with the products you sell individually — and most off-the-shelf approaches break that relationship. This app keeps it intact.
Every bundle is defined as a bill of materials (BOM): a parent product mapped to its component variants and quantities, stored in Shopify metafields. When an order is created, an orders/create webhook fires and the app deducts each component's stock at the correct location using the Admin GraphQL API (inventoryAdjustQuantities). Sell a kit, and the shared components drop everywhere they appear — single listings, other bundles, multipacks — so your available-to-sell numbers stay honest across multi-location inventory.
This is a build-to-order product. ECOSIRE designs the BOM model around your catalog, builds the app on Shopify's current API version, installs it on your store via OAuth with least-privilege scopes, and configures bundle pricing, component mapping and low-stock thresholds with you. It is not an instant App Store download — you get something fitted to how your kits actually work, plus a real engineer who installed it.
You receive bundle-specific pricing and discounts, component low-stock alerts, multi-location bundle availability (a kit is only sellable where every component is in stock), and an admin view of which BOMs are at risk. Refunds and cancellations restock components correctly. Built honestly, installed properly, supported after launch.
What you get
- A custom Shopify app built on the current Admin GraphQL API version and installed on your store via OAuth
- Your full bundle/kit/multipack catalog modeled as bill-of-materials definitions in metafields
- Configured orders/create, orders/cancelled and refunds/create webhooks for automatic component deduction and restock
- Component-level low-stock alerting configured to your thresholds and notification channel
- Multi-location availability rules so kits only sell where every component is stocked
- Admin BOM dashboard plus a short written runbook and a walkthrough session for your team
Who this is for
Multipack & subscription brand operator
Sells the same SKU as singles, 3-packs and 6-packs and needs one shared pool of component stock so multipacks never oversell the singles.
Kit-based DTC merchandiser
Builds curated starter kits and gift sets from existing catalog items and wants accurate stock plus bundle-specific pricing without manual reconciliation.
Multi-location operations manager
Fulfills from several warehouses or stores and needs bundle availability computed per location based on the limiting component.

Frequently Asked Questions about Bundles & Kitting Inventory Manager
How long until the app is built and installed?
This is a build-to-order product, not an instant download. After your purchase we hold a short scoping call to map your bundles to a BOM model, then build and install the app on your store. A typical engagement is delivered in about 10 to 15 business days depending on catalog size and how many bundle and multi-location rules you need. You get a confirmed timeline in writing before we start building.
Do I get ongoing support and updates after launch?
Yes. ECOSIRE installed it, so ECOSIRE supports it. The build includes a post-launch support window for fixes and questions, and we keep the app compatible as Shopify rolls new Admin API versions. Ongoing maintenance, BOM expansion or new bundle logic can continue under a support arrangement we agree on — you are never left with an orphaned app.
Will this oversell components that are shared across bundles and single listings?
No — preventing exactly that is the point. Each component has one inventory pool. When a kit, multipack or single listing sells, the app deducts the shared component everywhere it appears using the Admin GraphQL API, and recomputes the available-to-sell for every bundle that depends on it. A bundle becomes unsellable as soon as any one of its components runs out.
Does it work with Shopify's multi-location inventory?
Yes. Deductions are applied at the correct location, and a bundle is only marked sellable at a location where every component is in stock there. The limiting component determines per-location bundle availability.
What happens on refunds and cancelled orders?
The app listens to the refunds/create and orders/cancelled webhooks and restocks the affected components automatically, in the right quantities and at the right location, so a return or cancellation puts shared inventory back into the pool accurately.
