What Is Shopify App Development and How Does It Work
Shopify application development is the process of building software that extends what a Shopify store can do beyond its default theme and checkout tools, covering everything from small workflow automations to full custom apps connecting Shopify to your ERP or CRM systems.
Most merchants start with apps from the Shopify App Store, since thousands of developers develop Shopify apps for niches like reviews, subscriptions, or shipping. When a business has a workflow no off-the-shelf app supports, teams turn to custom Shopify apps development.
At ENCYPHERS, our Shopify app development service covers both directions. We build and submit public apps to the Shopify App Store for merchants wanting broader reach, and we build private, custom-only apps when no listed app can replicate what a business specifically needs.

Our Shopify App Development Process
A structured five-stage Shopify app development process built to reduce risk and keep your custom Shopify app on schedule.
01
Discovery and Technical Scoping
We start by understanding your store, current tech stack, and the specific problem you need the app to solve. From there, we define the app's architecture, required Shopify APIs, third-party integrations, and a realistic timeline and cost estimate, and confirm whether it should be a private custom build or a public Shopify App Store submission, since that decision shapes every technical requirement that follows for the rest of the Shopify app development process before development starts.
Custom Shopify App vs.
Public App Store App
Choosing between a custom Shopify app and a public Shopify App Store app depends on ownership, cost structure, and how closely the app needs to match your exact workflow versus a general merchant audience.
Custom Shopify App
Public App Store App
You fully own the app's source code, all data, and full IP rights forever
One-time build cost plus ongoing maintenance, tied to app complexity overall
Built entirely around your exact workflow, with no unused settings enabled
Skips Shopify's app review entirely, since it's never publicly listed
Extends and adapts freely as your business and requirements grow over time
Best for specific workflow gaps, B2B needs, or enterprise features today
The vendor owns and controls the app's code, updates, and its data outright
Recurring monthly subscription fee billed regardless of feature usage always
Limited to whatever settings the vendor has already built into it directly
Must clear Shopify's public review before the app can go live anywhere
May force a switch to another app entirely as your business scales up today
Best for common needs like reviews, basic upsells, or simple email tools

How Shopify App Development Actually Works
Shopify app development follows a defined technical path, from scoping the right API to choosing between a public or custom app, so merchants know what actually happens before, during, and after a Shopify app development project begins.
Discovery and Requirement Mapping
Shopify app development starts with defining exactly what the app needs to do, for whom, and which existing systems it needs to work alongside, so the build is scoped around your actual workflow instead of guesswork from day one.
Choosing the Right Shopify API
Depending on scope, development happens against the Shopify Admin API, GraphQL Admin API, Storefront API, or Shopify Functions, each suited to different tasks like backend automation, storefront features, or checkout logic.
Public vs Custom App Decision
We help decide whether the app should be a public Shopify App Store listing, or a private custom build made only for your store. Shopify deprecated the old private-app category in January 2022 in favor of this custom-app model.
Interface Design With Polaris
Admin-facing tools are built using Shopify's Polaris design system so the app feels native inside Shopify, while customer-facing features get a custom storefront interface designed around your specific brand and user experience.
Development, Testing and Security
Our Shopify app developers write and test the app continuously through development, including load testing for high-traffic stores and security testing for any app handling payment, checkout, or customer data throughout the build.
Cost, Timeline and Launch Planning
Shopify app development cost and timeline depend on scope and integration count, with ongoing maintenance priced separately, and launch planning includes Shopify App Store submission steps if the app is being made public.
Build the Right Shopify App
Whether it's a custom internal tool or a public Shopify App Store app, our developers can scope and build it.

Frequently Asked Questions
About Shopify App Development
Shopify app development is building software that extends a Shopify store's functionality beyond its default features, using Shopify's Admin API, Storefront API, or Shopify Functions. It includes both public apps listed on the Shopify App Store, which any merchant can install, and custom apps built for one specific merchant only, which never go through Shopify's public review process and are typically used for internal, business-specific workflows that no listed app supports.
The main reasons and benefits of Shopify app development are automating manual work, connecting Shopify to other business systems, and adding features that off-the-shelf apps don't offer. For growing merchants, a well-built custom app can also reduce the number of separate paid subscriptions running on a store, since several disconnected apps can often be replaced by one custom-built tool designed specifically around how your business actually operates day to day.
Public apps are listed on the Shopify App Store and available to any merchant after passing Shopify's review process. Custom apps are built for one store only and never go through public listing. Private apps used to be a third category, but Shopify deprecated private apps in January 2022, replacing them with custom apps that use the same access model without ever needing to be listed publicly on the Shopify App Store for other merchants to discover.
To develop a Shopify app, our team starts with your specific workflow gap, whether you want to develop an app privately for internal use or for Shopify's public App Store. We've spent years developing Shopify apps for brands who didn't know how to scope requirements on their own, and we handle that scoping conversation as the first step before any code gets written, public or custom.
It starts in your store's admin settings under "Develop apps," where you generate API credentials for a private, custom-only app. ENCYPHERS can either build directly against those credentials once you have enabled them, or walk you through the exact settings if your team wants to enable custom app development in-house before we begin the build.
