Shopify App Development
Need a feature Shopify does not ship, or an app that connects your store to the rest of your business? APPSDAPPS builds custom, private and public Shopify apps with the current Shopify platform tooling, from a small internal tool to a subscription app for the App Store.
Shopify apps we build
Custom and private apps
Internal tools for a single store or brand: bulk editors, order dashboards, approval flows, B2B pricing and wholesale features.
Public App Store apps
Multi-store apps with OAuth install, managed pricing or the Billing API, GDPR webhooks and the review requirements Shopify enforces.
Embedded admin apps
Embedded interfaces built with App Bridge and Polaris so merchants get a native-feeling experience in the Shopify admin.
Theme app extensions
App blocks and embeds that merchants add from the theme editor, without editing theme code.
Checkout UI extensions and Functions
Custom checkout elements, plus Shopify Functions for discount, delivery and payment customisation logic.
API integrations
Admin GraphQL API, webhooks and bulk operations to sync products, orders, customers and inventory with external systems.
Custom storefront features
Product configurators, wishlists, subscriptions, size guides and personalisation built as app blocks or Storefront API experiences.
Maintenance and API upgrades
Keeping existing apps working as Shopify retires API versions and changes platform requirements.
How we build a Shopify app

Develop and test
Built and tested on development stores, with demos at each milestone and automated checks for critical flows.
Release and support
Installation on your store or submission to the Shopify App Store, followed by monitoring and updates.
Shopify app development FAQs
What is the difference between a custom app and a public app?
A custom app is built for one store or organisation and installed directly. A public app is distributed through the Shopify App Store to many merchants, so it needs multi-store installation, billing and App Store review compliance.
Which technologies do you use for Shopify apps?
We build with the Shopify CLI and current app templates, typically using Node.js and React with Polaris and App Bridge, and the Admin GraphQL API. We can match your preferred stack and hosting where it makes sense.
Can you take over or fix an existing Shopify app?
Yes. We audit the code, API versions, webhooks and security, then fix defects, upgrade API versions and add features.
Can an app change my checkout?
Yes, within what Shopify allows. Checkout UI extensions and Shopify Functions cover many customisations such as custom fields, discounts, delivery options and payment rules.
How long does a Shopify app take to build?
A focused internal app often takes a few weeks. Public apps with billing and review requirements take longer. We give a written estimate after a short discovery call.
