Shopify app development
When the store
needs to do more.

The product
An app that lives
inside Shopify.
A sample subscriptions app. It sits inside the Shopify admin, adds to the checkout, and runs its discount rules as Shopify Functions.
What's included
Features built
for your store.
Every store reaches a point where the app store can’t help. That is where we come in. We build exactly what your business needs, and we build it well.
-
Custom app development
Public or private Shopify apps built to your brief. We use Shopify’s current App Bridge and extension tools, so the app stays stable.
-
Checkout and Functions
Checkout UI extensions and Shopify Functions. Functions now handle discount, shipping and payment rules, since Scripts stopped on 30 June 2026.
-
Systems integration
Reliable links to your ERP, CRM, warehouse or accounting system, so orders and stock stay in sync on their own.
-
APIs and webhooks
Shopify’s Admin and Storefront GraphQL APIs and webhooks, with error handling and safe retries. Your order and stock data stays correct.
-
Fewer apps
Replace a pile of paid apps, with their monthly fees and slower pages, with one tool that does exactly what you need.
-
Maintenance
We keep your app up to date with Shopify’s changes, watch it, and support it, so it keeps working.
The stack

expects.
Embedded apps, checkout UI extensions and Functions, built with the same tools Shopify uses.

The app store can only do so much
For a while, a ready-made app does the job. Then you need it to work a little differently. Or talk to your warehouse. Or stop charging you every month for the small part you use. And you are stuck. A custom app removes that limit. It does exactly what your business needs, connects to the systems you already use, and belongs to you.
Built on what Shopify supports now
Over the last two years Shopify has moved away from fragile hacks to a clear set of tools. UI extensions for the screen, Functions for the logic, the Branding API for style, and Web Pixels for tracking. Shopify Scripts ended on 30 June 2026, and the old checkout ended in August. We build on the current, supported tools, so your app keeps working when Shopify changes things.
When the store needs more
Custom apps for
the hard jobs.
Some things don’t belong in a theme. We build private apps for custom features, and links to the systems you already use. We also build Shopify Functions for the discount and checkout rules that Scripts used to handle.
- Private and custom apps
- Shopify Functions for checkout logic
- ERP, POS and fulfilment integrations
- Tested with your real order numbers
How we work
How we build
your app.
01
Scope
We agree exactly what the app must do and which systems it connects to. Then the build has a clear end.
02
Build
We build with Shopify’s current APIs and tools, and we plan for correct data from the start.
03
Connect and test
We connect the systems, test the unusual cases, and check that orders and stock stay correct in real use.
04
Launch and support
We launch it, watch it, and keep it up to date as Shopify and your business change.
Behind the build
Extensions, logs
and accounts.
Three things that make an app easy to run and support.
-
Extensions as code Checkout and customer account extensions, released as versioned code. -
Event log Webhooks and background jobs you can see and run again. -
Customer account Subscribers change their own plan, without emailing support.
Where Scripts used to sit
Logic that runs
inside checkout.
Scripts are gone. The discount, shipping and payment rules they used to hold now belong in Shopify Functions. Functions run on Shopify’s own servers. We move your rules across and keep the checkout working the way your customers expect.
- Discount and shipping logic as Functions
- Checkout UI extensions for the visible parts
- Web Pixels, so your analytics keep working
Questions
What people ask
about Shopify apps.
It depends on the job. A private or custom app suits one store’s needs. A public app suits something you want to offer to other stores. We will tell you which fits.
Yes. Reliable connections are a big part of our work. We add checks, retries and logs, so the data stays correct.
Often, yes. It can pay for itself in cancelled app fees. It is also faster and does exactly what you need.
We build on the tools Shopify supports today, so it keeps working. And we keep it up to date.
They won’t be running any more. Scripts stopped working on 30 June 2026. Any discount, shipping or payment rules that lived there need to be rebuilt as a Shopify Function. Functions can do more anyway. We do this move often.
