What You're Actually Paying For

A mobile app is not one thing. When you hire an app development company, you're paying for people's time across several overlapping roles:

  • Design. UI/UX designer mocks up screens, flow, buttons, colours. Typically 2–4 weeks for a simple app.
  • Backend development. Servers, databases, APIs that make the app work. Usually the longest phase.
  • Frontend development. The code that runs on your user's phone (iOS, Android, or both).
  • Testing. Finding bugs. Often ignored until the end, which makes it expensive.
  • Project management. The person who keeps everyone on track and talks to you.
  • Deployment. Getting the app into the App Store and Google Play, then fixing post-launch issues.

The cost depends on: how many of these roles you need, how experienced each person is, how long they take, and how many unexpected problems pop up.

Types of App Dev Companies in Mumbai

Freelance Developers

Rate: ₹500–₹2,500 per hour. Often quote projects at ₹3–₹15 lakhs.

When it works: Small MVP (minimum viable product), simple feature, tight budget, or you know exactly what you want.

When it doesn't: You need someone to manage complexity. Freelancers disappear. No one else knows the code. No backup if they get sick or quit mid-project.

Small Teams (2–5 People)

Rate: ₹8–₹20 lakhs for a basic app. ₹20–₹35 lakhs for something with more complexity.

When it works: You want accountability and a small group that can move fast. You may get a dedicated project manager.

When it doesn't: They disappear mid-project to chase bigger clients. Limited expertise in niche areas (IoT, AR, machine learning). No account manager to handle your questions.

Mid-Size Agencies (10–50 People)

Rate: ₹25–₹50 lakhs for an app. ₹50L+ for apps with payment integration, complex backend, or multiple features.

When it works: You have a complex product. You want proper project management, design, testing, and backup support. You want someone who can scale if your app needs new features in six months.

When it doesn't: You have ₹3–₹8 lakhs and expect a professional result. They will either decline or cut corners. You may get a junior team assigned.

Large Firms (100+ People)

Rate: ₹50L–₹2 crores.

When it works: You are a serious company (VC-funded, large revenue). You need iOS and Android and web. You need compliance, security, and support for years. You need them to manage vendor relationships.

When it doesn't: You are early-stage. You will be a small client on a large team. Decision-making is slow. Costs balloon fast.

Real Cost Ranges (2026)

These are typical quotes for an app that needs a backend, works on iOS and Android, and has 3–6 screens of functionality:

  • Basic MVP (low complexity): ₹5–₹12 lakhs. Timeline: 3–5 months.
  • Standard app (medium complexity): ₹15–₹35 lakhs. Timeline: 5–7 months.
  • Complex app (payments, real-time data, integrations): ₹40–₹75 lakhs. Timeline: 7–12 months.
  • Enterprise app (advanced security, high traffic, custom backend): ₹75L–₹2 crores+. Timeline: 12+ months.

These figures assume you are hiring a team in India. If you use a global firm or a top Silicon Valley agency, multiply by 3–5.

Note: Avoid anyone quoting ₹2 lakhs for an app. That price signals either they don't understand scope, they will disappear, or the app will not work.

What Affects Price

iOS + Android or Just One?

One platform (Android-only or iOS-only) costs less, but you exclude half your market. Most companies build for both. Some use cross-platform frameworks like React Native or Flutter, which cut cost by 30–40% but sacrifice performance for speed.

Third-Party Integrations

Connecting your app to Razorpay or Instamojo for payments, WhatsApp API for notifications, or Google Maps for location—these add time. Each integration costs ₹1–₹3 lakhs depending on complexity.

Real-Time Features

If your app needs live chat, notifications, or real-time data sync (like Uber or Swiggy), the backend becomes complex. Plan for ₹10–₹20 lakhs extra.

Design Quality

A budget designer costs ₹2–₹5 lakhs. A great designer costs ₹8–₹15 lakhs. The difference shows in user retention. Don't skip this.

Post-Launch Support

App Store updates, bug fixes, server maintenance, new iOS/Android versions—most companies quote this as ₹1–₹3 lakhs per month (retainer). Plan for at least 6 months.

5 Questions Before You Hire

1. Do They Have a Portfolio in Your Industry?

Ask them to show you apps they've built in fintech, e-commerce, or logistics (or whatever you're doing). Ask for the app store links. Download the apps and use them. Can you tell if they understand your business model?

2. Who Will Be Your Day-to-Day Contact?

Large agencies will assign a project manager. Smaller teams may assign the founder or a senior developer. Either way, this person should understand your business, not just code. Interview them.

3. What Happens If They Miss the Deadline?

Get this in writing. Do they charge a penalty? Do they add team members at no extra cost? A realistic response is: "We've built in buffer. We've delivered on time in X% of projects. If we slip, we add team members." If they promise zero delays, they're lying.

4. What Does ₹X Lakhs Actually Include?

Does it include post-launch bug fixes? How many months? Does it include design changes? How many rounds? Get a detailed statement of work (SOW) that lists deliverables, timeline, and what requires extra payment.

5. How Do You Handle Scope Creep?

You will ask for new features mid-project. A good company says: "That's a new feature. It costs ₹X lakhs extra and adds Y weeks." A bad company either says "No problem," (and then everything falls apart) or makes you feel guilty for asking.

Red Flags to Avoid

  • They don't ask about your business model. If they jump straight to technical questions, they don't care about the outcome.
  • They guarantee launch in 6 weeks for ₹5 lakhs. Impossible. Either the app won't work or they will ghost you after launch.
  • No contract or SOW. Never sign. Get specifics in writing.
  • They can't explain why something costs what it does. A good company breaks down cost: design ₹X, frontend ₹Y, backend ₹Z. If they can't, they're either new or overcharging.
  • They don't offer post-launch support. The app is fragile on day one. You need someone available.
  • They don't use version control or have a testing process. These are table stakes. If they don't mention them, walk away.
  • They pressure you to decide in a day. A serious company will wait a week for your decision.

The bottom line: A mobile app costs ₹5–₹50 lakhs in Mumbai, depending on scope. The cheapest option often fails. The most expensive option often delays. Choose a company that understands your business, can explain what they're charging, and has references you can call. Ask for a trial project (small feature or MVP) before committing to a full build. If it goes well, move forward. If it doesn't, you learned cheaply.
