Custom Shopify
Development Services
Webmaken builds custom Shopify apps that add the features your store is missing, connect Shopify to the systems you already use and automate the manual work behind your orders. From private apps for one store to public apps for the Shopify App Store, we build on Shopify's own APIs and extension points.
Shopify development services built around your store
Custom & Private Shopify Apps
When no app in the Shopify App Store does exactly what you need, we build a custom app for your store alone. Think custom product builders, bespoke pricing or B2B workflows, internal tools for your team and admin screens that fit the way you run your business. Custom apps are installed only on your store and are not listed publicly.
Public Apps for the Shopify App Store
Have an idea that could help other merchants? We build embedded public apps with OAuth installation, Shopify Billing API plans and an admin interface that follows Shopify's design guidelines, then prepare the app for Shopify's App Store review and listing requirements.
Theme App Extensions & App Embeds
We add your app's features to the storefront through theme app extensions, app blocks and app embeds. Merchants can place and configure them in the theme editor without editing theme code, and they work with Online Store 2.0 themes.
Checkout, Admin Extensions & Shopify Functions
We build checkout UI extensions, admin actions and blocks, and Shopify Functions for custom discounts, delivery and payment customisations, and cart and checkout validation. Some of these options depend on your Shopify plan – for example, several checkout customisations require Shopify Plus – and we will tell you up front what is possible on yours.
Integrations, Automations & Webhooks
We connect Shopify to your ERP, CRM, warehouse or 3PL, payment, accounting and marketing tools using the Shopify Admin API (GraphQL) and the Storefront API. Webhooks and scheduled jobs keep orders, stock levels, customers and products in sync, so your team spends less time copying data by hand.

Our Shopify development process
Discovery & requirements
We learn how your store works, what is slowing you down and which systems are involved, then check whether an existing app could do the job before recommending a custom build.
Technical planning
We choose the right Shopify extension points and APIs, define the data that flows between systems, the access scopes the app needs and any limits set by your Shopify plan.
UX & app design
We design the admin screens, storefront blocks and settings so that they feel native to Shopify and are easy for your team or other merchants to use.
Development & testing
We build the app and test it on a development store with realistic products, orders and edge cases before anything touches your live shop.
Launch & ongoing support
We install the app on your store or submit it for App Store review, monitor it after launch and keep it up to date as Shopify releases new API versions
Fast, secure and maintainable Shopify apps
A good app should not slow your store down. We favour theme app extensions over editing theme code, load storefront scripts only where they are needed and respect Shopify's API rate limits, so your shop stays quick for customers.
We request only the access scopes an app really needs, verify webhooks, store credentials securely and handle customer data with care. And because Shopify updates its APIs regularly, we can maintain your app after launch – updating API versions, fixing issues and adding features as your store grows. Need a new store or theme as well? See our Shopify and CMS development services.
