Fixed bundles and multipacks
Set up in the Shopify Bundles app, with components, quantities, and a price for each one.
The Problem
Your Kits Sell Fine Until the Stock Count Stops Adding Up
It shows up when Shopify product bundles share parts with single products, or when a kit needs to reach a warehouse that only knows component SKUs.
01 · Kit stock
Selling a kit doesn't touch the serum on the shelf.
Each sale deducts every component, so shared parts stay accurate.
02 · Phantom counts
The site shows 12 serums while the warehouse has 9.
Counts match the shelf because the math runs at checkout.
03 · 3PL flags
Your 3PL can't pick the kit SKU, so it flags every order.
Your 3PL gets component lines or the kit SKU it stocks.
04 · Recount delays
Kit buyers wait while someone recounts shelves by hand.
Bundles map to their components and quantities before anything goes live.
Your skincare starter kit holds a cleanser, a serum, and a travel bag. The kit has its own SKU and its own stock count, so selling one doesn't touch the serum on the shelf. On Monday, the site shows 40 kits and 12 serums, and the warehouse has 9 serums. Your 3PL can't pick the kit SKU, so it flags every order. Customers who bought kits wait while someone recounts the shelves by hand.
We start by mapping each bundle to its components and quantities, then set up Shopify's bundle tools or a custom build where they stop. Each sale deducts every component, so shared parts stay accurate across kits and singles. Your 3PL receives the component lines or the kit SKU it stocks. Your counts match the shelf because the math runs at checkout, not in a Friday spreadsheet.
Stock deducted per component
A kit sale removes each part by its quantity, so your shared items stay counted once.
Custom boxes that price right
Shoppers fill a box from your eligible items, and the price follows the box size.
Kits your warehouse can pick
Components or pre-packed kit SKUs reach the 3PL the way its shelves are labeled.
Our Bundle Build Process
From Free Catalog Review to Live Bundles in Five Steps
You approve each bundle's components, prices, and stock rules on paper, then watch the test orders prove every count with us.
We map your bundles, shared components, and how your 3PL or ERP counts kits. You get a plain answer on whether Shopify's own bundle tools cover you, before any quote.
What's Included
What You Get With Custom Shopify Bundles
Bundle setup or a custom build, component stock rules, pricing, 3PL and ERP mapping, and test orders that prove your counts before launch.

What Our Clients Say
What Clients Say After Launch
Feedback from ecommerce teams we have built catalog and stock logic for.
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.
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.
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.

Work Culture
Why Shopify Brands Trust Us With Their Bundles
A bundle is only as good as its stock math. These habits keep your kits sellable, your warehouse calm, and your margins visible.
Shared parts counted once
When one lid ships in three kits and on its own, we map it once. Every sale pulls from the same count, so shared parts stop drifting.
Warehouse sees real SKUs
Your 3PL gets the components or the kit SKU it stocks, not a label it can't find. Pick lists match the shelves on day one.
Prices that add up
Every bundle shows its saving against the separate items. Discounts stack the way you approved, so your margin stays visible.
Partial refunds tested first
We test returns of one item from a kit before launch. Your team knows what restocks and what the customer gets back.
The free app comes first
Shopify's free Bundles app covers fixed bundles and multipacks. If that's all you need, we'll tell you before we quote.
You own the bundle logic
Functions, rules, and data live in your store and accounts. Any developer can read the rules document and change a bundle later.
Overview
Who builds Shopify product bundles that keep component stock accurate?
DeveloperLook builds Shopify product bundles and kits that keep component stock accurate. We set up fixed bundles and multipacks, build mix-and-match boxes with tiered pricing, and map components to your 3PL, ERP, or WMS. Setups start at $600 and take 1 to 3 weeks for most stores, and we'll say when Shopify's free Bundles app is enough.

Good fit
Stores selling starter kits and multipacks
Your starter kit shares parts with single products, and stock counts drift a little after every sale.
Brands wanting build-your-own boxes
You want shoppers to pick any 3 items from your collection and see the box price update in their cart.
Shops shipping kits through a 3PL
Your bundle app sends the 3PL a bundle SKU it can't pick, so every kit order lands in its exception queue.
Teams with ERP or WMS kit records
Your ERP tracks pre-packed kits with a bill of materials, and Shopify's stock needs to agree with it.
Agencies with bundle-heavy clients
Your client wants custom gift boxes before the holidays, and your team is already booked with the theme.
Not a fit
A handful of simple bundles
You only sell a handful of simple bundles or multipacks. Shopify's free Bundles app covers that on any plan, and our $600 setup would add little.
One product with options
You want shoppers to design one product with options, engraving, or a preview. Our Shopify Product Configurator service fits that job better.
Bundles on subscription
You want bundles sold on subscription. Shopify's bundles don't work with subscriptions, so our Shopify Recharge Subscription Setup service builds them in Recharge.
Stock drift across channels
Your stock drifts across Amazon, eBay, and your store. Our Multichannel Inventory Sync service fixes counts across channels, not bundle rules.

Bundle development starts at $600 for up to 15 fixed bundles or multipacks in the Shopify Bundles app. Mix-and-match boxes with tiered pricing cost $1,600. A custom build on Shopify Plus with ERP or WMS kit sync costs $3,600. You get a fixed quote after a free catalog review.
Simple bundles go live in about 1 week. Custom boxes with discounts take 2 to 3 weeks, and a Plus build with ERP kit sync runs 4 to 6 weeks. Most of that time goes into testing your stock math, partial refunds, and the orders your 3PL receives.
Create Shopify product bundles whose stock comes from components, not a separate count. Shopify's own app works this way on any plan. A kit with its own SKU and its own stock count is what breaks inventory, because selling that kit doesn't touch your parts.
You install Shopify's free Bundles app, create a bundle, and pick its components and quantities. The bundle gets its own product page and price, while your stock comes from each part. Simple bundles and multipacks work on every plan, but a bundle can't contain another bundle.
Each sale deducts every component by its quantity in the bundle. A kit with 2 jars and 1 lid removes 2 jars and 1 lid from your stock. Availability follows the scarcest part, so the kit shows sold out once one component can't fill another.
Yes, and with Shopify's bundles, your 3PL receives component lines instead of a bundle SKU. Shopify's order data lists each component with a reference to its bundle. For kits your warehouse pre-packs, we map the kit SKU it stocks, so the right box ships.
Show the bundle price next to what the items cost separately, so the saving is clear. Simple bundles carry their own price in Shopify's app. Tiered or box-size pricing comes from Shopify's automatic discounts, a bundle app, or a discount function on Shopify Plus.
Yes, through a bundle app on any plan or a custom build on Shopify Plus. The free Shopify Bundles app covers multipacks and fixed product bundles. Shopify leaves mix-and-match to other apps or Plus builds. We set which items qualify, how many to pick, and each box price.
An app is better for most stores, starting with Shopify's own free app. Custom logic earns its cost when rules get specific: pricing by customer type, shared parts across many kits, or kits your ERP tracks. Custom functions need Shopify Plus, since other plans run them only in public apps.
Your ERP or WMS sees component SKUs, or a kit SKU when your warehouse pre-packs kits. Virtual bundles deduct components at checkout. Pre-packed kits get their own SKU and a bill of materials in the ERP, and we keep Shopify's kit stock in step with it.
