Shopify app development cost in India (2026): what a custom app costs

A custom Shopify app built for one store costs ₹80,000 to ₹6,00,000 in India in 2026, or $1,600 to $10,000 if you're an international brand. That's my published range. A single admin tool or one integration sits near the bottom. An app that connects several systems, or uses Shopify Functions and checkout extensions, sits near the top. Most builds take 45 to 60 days.

The range is wide because "a Shopify app" covers everything from a bulk price editor to a sync between Shopify, your ERP and your warehouse. Below is how the price breaks down, what you keep paying after launch, and when you shouldn't build anything at all.

What counts as a custom Shopify app?

A custom app is built for one store and installed only there. It isn't listed on the Shopify App Store, it doesn't charge you a monthly fee, and the code belongs to you. It talks to your store through Shopify's Admin and Storefront APIs, which is how it can read orders, update products, sync stock or add logic to checkout.

Building a public app for the App Store is a different project. That's a software product sold to thousands of merchants, with multi-store architecture, Shopify's app review, billing and support. It needs a different budget, and it isn't what this post prices. I don't build App Store products today.

What does a custom Shopify app cost by type?

For international brands the same work runs $1,600 to $10,000, and Functions work on Plus is scoped per project. Every price I charge is on one pricing page.

What moves the price?

Five things decide where a build lands in the range:

• How many systems it connects. Each outside system brings its own API, login method, rate limits and ways to fail. One integration is a contained job. Three is a project.
• How much logic it carries. An app that copies data is cheaper than one that makes decisions, such as which price applies to which customer or which warehouse ships an order.
• Whether it needs Functions or checkout extensions. These run inside Shopify's checkout, have their own limits and need careful testing before they touch real orders.
• How much order history it needs. By default, Shopify lets an app read only the last 60 days of orders. Reports that need full history need the read_all_orders scope and a one-time backfill.
• Whether it reads customer data. Apps that read names, emails or addresses fall under Shopify's protected customer data requirements, which add setup work.

What does a custom app cost after launch?

Three costs continue after handover.

1. Hosting. The app runs on its own small cloud setup. The written scope lists what yours needs and whose account it lives in.
2. API upkeep. Shopify releases a new API version every quarter and supports each one for at least 12 months. Plan on a check-up at least once a year so the app keeps working when an old version retires.
3. Changes. Your business will change, and the app will need to follow. I handle upkeep and new features inside a retainer of ₹40,000 to ₹80,000 a month ($1,000 to $3,000 abroad). It's 10% off with a 6-month commitment and 20% off with 12 months. Small one-off changes can be quoted as fixed jobs instead.

Is a custom app cheaper than an app subscription?

Sometimes. The arithmetic is simple:

A ₹2,000-a-month app is almost never worth replacing. At ₹15,000 a month, and especially when the fee climbs with your order volume, a one-time build often pays for itself inside three years.

The fee isn't the only cost. An app that does 80% of the job leaves your team running the other 20% by hand every week. Storefront apps also add scripts that slow your pages. For backend automation, I compare a custom app with Zapier and off-the-shelf apps in a separate post. For the storefront, my list of the apps I'd install first as an Indian D2C brand shows where renting still wins.

What I've built, and what it involved

Three custom builds show the spread:

• A merchandising dashboard for a D2C brand. A private app with read-only Admin API access and webhooks. It syncs about 2,000 products and more than 100,000 orders into its own database. On top of that it does stock forecasting and margin from cost prices that never touch Shopify, and turns reorders into purchase-order sheets that go to vendors as CSV files. Because the access is read-only, it can't change anything in the store.
• WeMust. A custom print-ordering flow with live pricing rules, tighter cart behaviour and automated invoices for a production-heavy store.
• Mum & You. Subscription flows rebuilt on Shopify's APIs, with private sync workflows, during their Magento to Shopify Plus migration.

Each one started from a written scope with a fixed price. That's what stops a custom build from turning into an open-ended bill.

How pricing and payment work

Every custom app follows the same steps:

1. Scoping sprint, ₹40,000 or $750. I map what the app has to do against what Shopify's APIs allow, and you get a written spec and a data map. The fee is credited to the build if you go ahead.
2. Written scope. A fixed price, a timeline and a Definition of Done. Most builds take 45 to 60 days.
3. Payment in three parts. 30% to start, 30% at the agreed milestone and 40% at delivery. No GST is added.
4. Handover. The code and IP are assigned to you.

Freelancer, agency or a senior solo developer?

In a sample of 379 INR fixed-price listings on Freelancer.com in October 2026, 89% had budgets of ₹37,500 or less. That buys small fixes. It rarely buys an app that touches your orders, your stock and your money, where a bug costs you sales.

Agencies charge more and put a project manager between you and the developer. I'm one senior developer who writes the code and publishes the price. I've written about freelancers versus agencies for Shopify work in India if you're weighing the two.

What I'd do

Write down three things first:

• the job the app has to do
• the systems it touches
• what that job costs you today, in staff time or app fees

If an existing app does it for a few thousand rupees a month, install it, and I'll tell you so. If not, a scoping sprint gives you the exact cost of a custom build before you commit to it.
