But app success isn’t just about coding. You need to follow the right steps, pick the right features, and plan your budget carefully. This blog breaks down the full process—from concept to submission—so you can build a Shopify app that actually gets used.

Types of Shopify App

Before building anything, it’s important to know what kind of app you’re making. Shopify apps generally fall into three types. Each serves a different purpose and suits different store needs.

1. Public Apps

These are available on the Shopify App Store. Anyone with a Shopify store can install them. If you’re targeting a wide audience, this is the way to go. Approval from Shopify is required.

2. Custom Apps

Built for a single store, these apps help merchants with specific needs that public apps can’t solve. They don’t need Shopify’s approval and can be installed directly by the store owner.

3. Private Apps

Similar to custom apps, but they’re created primarily for internal use or backend integrations. Shopify is phasing these out in favor of custom apps, but they’re still used in legacy setups.

Each app type has its own setup, scope, and distribution method. Knowing where your idea fits helps avoid rework later.

Steps to Build a Shopify App Successfully

Building a Shopify app takes more than writing code. You need a clear plan, the right tools, and a solid understanding of Shopify’s ecosystem.

Here’s a step-by-step breakdown to get started.

1. Define the Purpose of Your Shopify App

Start by identifying the problem your app will solve. Talk to store owners or browse existing apps for gaps. Clear goals help you stay focused during development and improve your chances of success on the Shopify App Store.

2. Choose the Right Type

Decide whether you’re building a public app, custom, or private app. This choice affects how you write your code, submit the app, and manage access.

3. Set Up Your Shopify Partner Account

To begin development, create a Shopify Partner account. This gives you access to tools like the Partner Dashboard, API keys, and app management features.

4. Select Your Tech Stack

Shopify supports a wide range of languages and frameworks. Popular choices include:

• Backend: Node.js, Ruby on Rails, PHP
• Frontend: React, Polaris (Shopify’s design system)
• Database: PostgreSQL or MongoDB

Pick tools your team is comfortable with to save time and avoid bugs.

5. Use Shopify APIs and Webhooks Properly

Shopify offers APIs like Admin API, Storefront API, and more. Use webhooks to stay updated on store events like orders or product changes. Make sure your app handles data securely and reliably.

6. Build the App Interface Using Shopify Polaris

Shopify’s Polaris design system helps you create a UI that fits perfectly into the merchant dashboard. It saves time and keeps your app consistent with the Shopify admin look and feel.

7. Test the Shopify App

Always test in a development store provided through your Partner account. This helps catch issues early, from permission errors to slow APIs. Consider real store scenarios, not just ideal ones.

8. Submit Your App for Review (For Public Apps)

If you’re building a public app, Shopify will review your submission. Make sure you meet all their app requirements. Include a privacy policy, a working demo, and proper billing setup if needed.

9. Launch and Monitor Your App

After approval, publish your app and monitor it. Track performance, user feedback, and crash reports. Use this data to fix issues and roll out updates.

Shopify App Development Cost Breakdown

Building a Shopify app involves different types of expenses—from initial planning to post-launch support. Costs vary based on the app’s type, complexity, and the team you hire.

Let’s break it down.

1. Estimated Cost by App Type

Before you begin development, decide what kind of Shopify app you’re building. Each app type comes with its price range and audience.

These are rough estimates. Actual pricing depends on features, timelines, and the development team’s location.

2. Shopify App Development Cost by Phase

Breaking your budget down by phase helps you track spending more clearly and avoid surprises. Each stage serves a key role in building a fully functional app.

A clear cost breakdown by phase helps you manage your project timeline and priorities more effectively.

3. Hourly Rate by Shopify App Developer Location

Your development team’s location affects your budget significantly. Here’s a quick comparison of hourly rates based on region.

If you’re working with a limited budget, hiring from Asia or Eastern Europe can offer strong value without cutting corners.

4. Ongoing Costs After Launch

Building the app is only the beginning. Maintenance, support, and scaling are part of long-term success.

Regular investment after launch keeps your app functional, secure, and competitive in the Shopify ecosystem.

📌 On average, the total budget to build a Shopify app ranges from $8,000 to $40,000, depending on app type, features, and who builds it.

Considerations for Building a Shopify App

Determine the Purpose

The apps are meant for solving specific challenges so you must consider your app’s purpose before building it. Determine your end goal in creating the app.

Determine the Type of the App

There are two types of apps that can be added to a Shopify store.

• Public apps: These can be listed so they appear in the Shopify App Store for purchase.
• Custom apps: Shop owners can hire developers to design a custom app specifically for their store.

Determine the cost to build a Shopify app?

Shopify apps generally cost between $8,000 and $40,000 to build, depending on how complex they are. Fewer features lead to lower price range. Average cost is about $20,000.

Determine Difficulty Level and Timeline

The apps might take up to a year and hundreds of hours of labor to build based on the difficulty level and features to be implemented. Hiring a professional developer is a wise idea.
