Shopify app development that fits how your store actually runs.
The app you need is rarely the one sitting in the store, and the closest match keeps forcing your team into workarounds that cost real hours. We are senior Shopify app developers who build custom and public apps, app extensions, embedded admin tools, and the API and webhook integrations that tie Shopify to the rest of your business. Sixteen years in commerce, with no junior bench and no handoffs.
When the App Store stops where your workflow really begins.
Most stores reach a point where the catalog of off-the-shelf apps runs out: a workflow no listing covers, an integration that has to behave a certain way, a process the team keeps doing by hand because no app does it right. That is where custom Shopify app development earns its keep. Maybe it is an order routing rule tied to your warehouses, a pricing engine your sales team controls, or a bulk operation that has to run against the GraphQL Admin API without timing out at your catalog size. We build that logic into Shopify itself, inside the admin and the checkout, on the same APIs Shopify rewards, so your store does the work instead of your people. The app becomes part of the build, tied straight into your Shopify development roadmap rather than bolted on beside it.

We're here to help you win, plain and simple.
Same senior team from kickoff to launch and beyond. We do not outsource, we do not disappear after go-live, and we do not hand you off.
Across every phase. Discovery, build, launch, and growth, the same senior team stays with you.

Whatever the app has to do, the same senior engineers handle it end to end, from the data model and the API surface to the admin screens your team will actually use every day. We build embedded apps with App Bridge and Polaris so they feel native, ship app extensions and Shopify Functions so the logic runs where it belongs, and design integrations that hold up under real order volume. Every engagement is scoped to your workflow and your stack, not a fixed package.
App development on Shopify, or Shopify Plus?
The plan you build for shapes what an app can do. Standard Shopify covers most custom and public apps; Shopify Plus unlocks checkout extensibility, Shopify Functions, and higher API limits. We build for both and tell you when a feature genuinely needs Plus.
Standard Shopify supports custom apps, public App Store apps, admin extensions, and the full API. For most stores, an app does everything you need here without the Plus price tag.
- Your app extends admin, storefront, or data
- You do not need custom checkout logic
- You want App Store distribution
Plus adds checkout extensibility and Shopify Functions, so apps can customize checkout, shipping, discounts, and B2B logic that standard plans lock down, with higher API rate limits for scale.
- Your app must customize the checkout
- You need Shopify Functions or scripts
- High call volume hits standard API limits

Proof behind the partnership, not just a pitch.
A few of the stores our senior team has shipped, scaled, and stayed on to grow.
Europa Eyewear
A Shopify Plus wholesale storefront with SparkLayer B2B and a Mirakl marketplace for a global eyewear house.
QC Supply
An enterprise Magento B2B rebuild with GroupBy search and Microsoft Dynamics ERP for a high-SKU distributor.
US Camera Pro
A Magento store for a camera and optics retailer, with M2E marketplace sync across channels.
The same senior engineers from kickoff to launch and beyond.
Most app projects go sideways for one of two reasons: the work gets passed to a junior team, or the developer vanishes the moment it ships and the first API deprecation breaks it. We built IWD to do the opposite, so the people who designed your app are the ones who keep it running.
Senior Shopify engineers, no junior bench
You work with the developers doing the work. We do not route your app to a training program and disappear once it ships, so the people who understand the code are the people who answer your questions.
Shopify Plus partner depth
We build on Shopify Plus and Shopify with the platform depth to use checkout extensibility, Shopify Functions, B2B, and Markets correctly, so your app uses the right tool instead of a fragile workaround.
Sixteen years building commerce
We have shipped storefronts, integrations, and apps across high-volume DTC, B2B, and complex multi-store catalogs since 2008. App work sits on top of real commerce experience, not theory.
We build, then we stay
Most clients keep us on after launch for new features, API upgrades, and growth work. The team that built your app is the team that keeps it current as Shopify changes underneath it.
A clear path from first call to a shipped app.
Discover
We map the workflow, the systems your app has to touch, and the API surface it needs. You get a clear definition of done before anyone opens an editor.
Architect
A phased plan with scope, timeline, and a real number. We decide custom or public, the data model, and the integration shape, and you sign off before we build.
Build
Two-week sprints, weekly demos, and a shared backlog. The same senior engineers ship to Shopify standards every cycle, against a staging store you can click through.
Ship & support
We handle App Store review or the custom install, watch it under real load, then stay on for features, API upgrades, and the work that keeps it healthy.
What merchants ask before they hire our Shopify app developers.
What is the difference between a custom Shopify app and a public app?
A custom app is built for one store and installed only on that store, which is the right call when the logic is specific to how you run your business. A public app is listed on the Shopify App Store for any merchant to install, which fits when you want to productize and distribute it. We build both, and we help you decide which model serves the goal before any code is written.
Can you take over a Shopify app another developer built?
Yes, and it is one of the most common ways merchants start with us. We run a code and architecture review first, document what we find in plain language, then give you a prioritized plan before touching anything, whether the app is broken, abandoned, or simply due for a rebuild on the current APIs.
Do you build on the latest Shopify app architecture?
Yes. We build embedded apps with App Bridge and Polaris, use the GraphQL Admin API, and ship app extensions, admin blocks, checkout extensions, and Shopify Functions so your app lives inside the admin and the storefront the way merchants now expect. We keep apps current as Shopify deprecates older APIs.
How long does a Shopify app development project take?
A focused discovery and architecture plan lands in two to three weeks. A custom app for a single store typically runs four to ten weeks depending on the integrations involved. A public App Store build, including the listing review, usually runs three to five months. You get a real timeline in week one.
How do you scope and quote a Shopify app project?
Every engagement is scoped to your app: the workflows, the external systems it touches, the API surface, and whether it is custom or public. You get a firm, itemized quote on the first call, with no long sales cycle, so you know exactly what you are committing to before anything begins.
Can your Shopify app developers handle API and webhook integrations to our other systems?
Yes. Connecting Shopify to an ERP, a PIM, a 3PL, or a CRM is core to most of the apps we build. We design webhook pipelines that stay reliable under load, handle retries and idempotency, and keep data in sync both ways so the store and the back office finally agree.
