The most common question I get from business owners who contact us is some version of: "How much does it cost to build software?" The honest answer has three parts โ€” and most agencies only give you the first one.

Part 1: The Project Cost

A basic business web application (customer portal, inventory system, booking system) with a database, user authentication, an admin dashboard, and an API typically costs โ‚น1.5 lakh to โ‚น6 lakh ($2,000โ€“$8,000) from a reputable Indian development firm. Mobile apps (cross-platform, Flutter) start around โ‚น2.5 lakh ($3,000) for a simple MVP and go up to โ‚น20 lakh+ for feature-complete consumer applications.

These ranges assume a fixed-price contract where the scope is agreed before work begins. If you hire on a time-and-material basis โ€” paying per hour or per day โ€” the final cost is impossible to predict at the start, and almost always exceeds the initial estimate.

Part 2: What Drives the Cost Up

Third-party integrations are the single biggest cost multiplier most clients don't anticipate. Connecting your software to a payment gateway (Razorpay, Stripe), an SMS provider, a GST API, or an existing ERP system can add โ‚น50,000โ€“โ‚น3 lakh per integration depending on the API quality and documentation. Budget for each integration separately.

UI/UX design is the second surprise. A development quote often covers coding, not design. If you need pixel-perfect custom interfaces rather than Bootstrap templates, expect โ‚น40,000โ€“โ‚น1.5 lakh for a proper design phase before a single line of code is written.

Compliance requirements add cost too. If your software handles health data, financial data, or data of EU citizens, you need additional security controls, audit logging, and potentially a security review โ€” none of which is included in a standard development quote.

Part 3: Post-Launch Costs Nobody Mentions

Hosting: a production-grade AWS setup for a typical web application costs โ‚น8,000โ€“โ‚น25,000 per month depending on traffic and redundancy requirements. Maintenance: software requires updates, security patches, and occasional bug fixes. Budget โ‚น8,000โ€“โ‚น25,000 per month for maintenance if you don't have an in-house developer. Feature additions: most software needs changes after launch. A fixed maintenance retainer is more predictable than paying per change.

Why Fixed-Price Is Almost Always Better for Indian Clients

Time-and-material billing puts all the risk on you. If the developer underestimated the complexity โ€” which is common โ€” you pay the difference. With a fixed-price contract, the development firm absorbs that risk. The price you agree to is the price you pay, regardless of what happens internally.

The tradeoff is that you need a detailed scope document before work begins. This takes more time upfront but saves enormous amounts of money, stress, and relationship damage later. At iSocialize, we spend the first 2โ€“3 weeks on scoping before we quote anything. Book a free scoping call โ€” it's the most valuable 30 minutes in any software project.
