Custom Shopify apps that do exactly what you need
Bespoke Shopify app development for merchants that have outgrown off-the-shelf solutions. Public apps, private apps and embedded admin tools built to extend Shopify's native functionality.
Sometimes the right app does not exist yet.
The Shopify App Store covers most common requirements. But when your business has a genuinely unique process, a custom Shopify app is often the cleanest solution. No workarounds, no third-party dependency, no paying for features you do not need.
We build private apps for internal workflows, embedded admin tools for your operations team, and public apps for merchants. All built on Shopify's current APIs and built to Shopify's standards.
Built for your store. No recurring fees, no vendor risk.
Private apps solve specific internal problems without the overhead of a managed subscription. Embedded admin tools bring custom workflows directly into your Shopify admin: order management dashboards, bulk editing tools, internal reporting interfaces. Built around how your operations team actually works.
Customise Shopify's commerce logic at the platform level.
Shopify Functions let you modify core checkout behaviour, including custom discount logic, shipping rate calculations and payment method filtering, without a workaround app. Alongside Functions, we build robust API integrations connecting Shopify to your ERP, WMS or CRM. Proper error handling, logging and retry logic. Not fragile webhook chains.
Stores we have built and extended on Shopify
Shopify moves fast. Your app needs to keep up.
Shopify regularly updates its APIs and deprecates older versions. A custom app without ongoing maintenance will eventually break. We offer retainers that cover API version upgrades, Shopify breaking change management and feature development so your app stays working as the platform evolves.
Common questions about custom Shopify apps
A private Shopify app is a custom app built exclusively for one store. It is not listed on the Shopify App Store and is not available to other merchants. Private apps are the right choice when you need functionality specific to your business that no existing app provides.
When the existing options require significant workarounds, charge for features you do not need, introduce unacceptable performance overhead or create a third-party dependency that concerns you. A custom app costs more upfront but often costs less over time.
Yes. Shopify Plus gives access to additional APIs and features that standard Shopify does not, including Checkout Extensibility and more granular B2B functionality. We build apps that make full use of the capabilities available at each plan level.
A straightforward private app can take two to four weeks. A more complex embedded admin tool or public app typically takes six to twelve weeks, depending on scope. We provide a clear timeline after scoping.
Yes. Shopify regularly updates its APIs and deprecates older versions. Without maintenance, a custom app will eventually break. We offer ongoing maintenance retainers that cover API upgrades, Shopify breaking changes and feature development.
Yes. We review the existing codebase, assess its quality and provide an honest view of whether to maintain and extend it or rebuild it on cleaner foundations. We will not tell you to rebuild something that does not need rebuilding.
