We had a different kind of problem. People were visiting the store, adding products to their carts, and then disappearing before they finished the order. We had tried a few apps and made changes here and there, but nothing really seemed to solve the bigger issue. The team went through the shopping experience with us and pointed out things we hadn't really noticed ourselves. They cleaned up the cart and checkout flow, made the mobile experience much smoother, and helped us make the store feel easier to shop. I’m not going to pretend we fixed everything overnight, but it finally feels like the store is helping the sale instead of getting in the way of it.
Ethan Parker
Founder of Elite Academy
The mobile experience is probably my favourite part of the new site. We had spent a lot of time making sure the desktop version looked right, and the team kept pushing us to think about how everything would actually feel on a phone too. They were right. The navigation is clean, the interactions feel natural, and everything we’ve tested so far works exactly as it should. They also went through the links, forms, integrations, and other details more than once before launch, which I really appreciated. And even after going live, we could still reach out when something came up. The whole process felt friendly, organised, and surprisingly straightforward.
James Whitmore
Head of Marketing of Lumen Outdoor
We had a pretty specific idea of what we wanted our website to become, but I wasn’t sure how easily we could explain all of it to a development team. There were quite a few moving parts, and we were working toward a deadline, so I expected a few things to get lost along the way. That never really happened. They understood what we were trying to achieve, kept us updated throughout the process, and got everything ready within the agreed timeline. The final site feels much easier to navigate, works beautifully on mobile, and is noticeably smoother for our customers. It was a huge relief seeing the original idea actually turn into the website we had in mind.

Why Businesses Trust Us With Bundle Development
Getting bundle inventory wrong means overselling or a confusing catalog, so the logic has to match how you actually sell. These are the habits we bring to every project.
App checked first
We tell you upfront if Shopify's native Bundles app or an existing bundle app already covers your case.
Inventory accuracy first
Every bundle type we build deducts stock from the correct component SKUs, so nothing gets oversold.
Mix-and-match built right
Customer-built bundles configured with the eligibility rules and pricing logic your catalog actually needs.
Fulfillment-aware
Bundles break down into real component SKUs for your 3PL, WMS, or ERP, not an abstract bundle line item.
Tested before it's live
Sandbox testing with real purchase and inventory scenarios before your live store is touched.
Built to be maintained
Documentation and an optional retainer so bundle logic keeps working as your catalog changes.
08Overview
Who builds custom Shopify bundles and kits that track component inventory correctly?
DeveloperLook builds custom Shopify product bundles and kits, fixed combinations, customer-built mix-and-match, or tiered bundle pricing, with inventory deducting from the correct component SKUs so nothing gets oversold. Projects start from $999, most complete in 1 to 3 weeks, and we recommend Shopify's native Bundles app first if a simple fixed bundle covers your case.

Who it's for
Stores selling fixed bundles or kits
You want to sell pre-set combinations, like a starter kit or multi-pack, with inventory that deducts correctly for each component.
Businesses wanting mix-and-match bundles
You want customers to build their own bundle or kit from a set of eligible products, which Shopify's native Bundles app doesn't support.
Stores with bundle pricing or discount rules
You need bundle-level discounts, tiered pricing, or a bundle price that isn't just the sum of its parts.
Businesses syncing bundles with ERP or WMS
Your bundles need to break down into individual component SKUs for your 3PL, WMS, or ERP so fulfillment and stock records stay accurate.
Stores outgrowing a bundle app
You're hitting the limits of your current bundle app, rigid combos, no mix-and-match, or poor inventory accuracy, and need custom logic instead.
Not a fit for
You need only simple, fixed bundles with no discount logic or mix-and-match. Shopify's native Bundles app handles this for free, and we'll tell you that upfront instead of building something custom you don't need.
You need general Shopify inventory tracking, low-stock alerts, or reorder logic beyond bundle components. Our Shopify Inventory Management System service covers that.
Your bundle components need to sync with an outsourced fulfillment provider's system. Our Shopify 3PL Integration service covers that.
Your bundle components are tracked in an ERP or a warehouse management system rather than just Shopify. Our Shopify ERP Integration or WMS Integration services cover that.
You're not on Shopify. This build is Shopify-specific, and other platforms would need to be scoped separately.

12FAQ
Frequently Asked Questions
Straight answers on Shopify bundle development, inventory deduction, and pricing logic.
How to create bundles on Shopify without breaking inventory?
We set the bundle to deduct stock from its component SKUs, not from a separate bundle-level count, so a sale always reduces the real inventory of each item inside it.
How does inventory deduct for bundle components?
Selling a bundle decrements each component's stock individually, and the bundle's own availability is calculated as the lowest available quantity among its parts, so it never shows as in stock when a component has run out.
Can you build kits and bundles that sync with my 3PL?
Yes. We break bundles down into their real component SKUs at the point of sale, so your 3PL receives component-level picking instructions instead of an abstract bundle SKU it can't fulfill.
How do I show bundle pricing and discounts?
Shopify's native Bundles app only sets a fixed bundle price. For tiered pricing, automatic bundle-level discounts, or volume-based pricing, we build custom logic using Shopify Functions to apply the right discount in cart and at checkout.
Can customers build their own bundle (mix and match)?
Not with Shopify's native Bundles app, it only supports fixed, predetermined combinations. Mix-and-match or build-your-own bundles need a custom configurator, which we build with the eligibility rules and pricing your catalog needs.
App or custom bundle logic: which is better?
We check bundle apps first. If a simple fixed bundle with accurate inventory covers your case, an app is the cheaper and faster path. Custom logic makes sense once you need mix-and-match, tiered pricing, or fulfillment-system sync an app doesn't handle.
How do bundles work with ERP or WMS SKUs?
Bundles break down into their individual component SKUs before they reach your ERP or WMS, so those systems see and track the real items, not a bundle line item they have no record of.
How much does custom bundle development cost?
Projects typically start from $999 for a single fixed bundle type with standard inventory handling, and scale up with mix-and-match logic, custom pricing rules, or ERP and 3PL sync. You get a fixed quote after reviewing your catalog.
