How to Budget a Custom Software or App Project in India in 2026

By the Devtech team · · 7 min read

If you run a small or mid-sized business in India and you are about to ask developers for quotes, the hardest part is not choosing a vendor. It is knowing what a fair number even looks like before anyone sends you a proposal. Quotes for the same brief can range from a few lakh to tens of lakh, and without a framework for comparing them, it is easy to either overpay or pick the cheapest bidder and run out of money halfway through.

This article sets out what custom software and app projects actually cost in India in 2026, how GST applies to your invoices, how fixed-price and time-and-material contracts differ for budgeting purposes, and the costs that most first-time buyers forget to set aside money for.

What a project actually costs right now

Pricing depends heavily on complexity, but recent Indian pricing guides give a useful band. A low complexity application typically costs Rs 1,50,000 to Rs 4,00,000 to build, and a small business automating one core workflow usually spends Rs 2 to 5 lakh on a first build. Once you move into a mid-market product with integrations, dashboards and multiple user roles, pricing guides from Indian development firms this year put most custom web applications, such as dashboards, booking systems and customer portals, between ₹5 lakh and ₹30 lakh.

If your plan includes a SaaS-style product with multiple paying customers, budget higher. SaaS products with multi-tenant architecture and billing integrations run ₹15–60 lakh to MVP. Modernising an old desktop or on-premise system is its own category: legacy system modernisation, moving a 15-year-old desktop application to cloud-based architecture, typically costs ₹10–40 lakh depending on data migration complexity.

On hourly rates, blended project rates run Rs 680 to Rs 1,700 an hour, with a dedicated developer on a monthly engagement at Rs 60,000 to Rs 1,00,000. Rates scale with seniority: hourly rates for Indian developers range from ₹800–₹3,500 depending on seniority, with junior developers in tier-2 cities charging ₹800–₹1,200, mid-level engineers in Bengaluru or Hyderabad charging ₹1,500–₹2,200, and senior architects and technical leads commanding ₹2,500–₹3,500 per hour. Treat any quote that is far below these ranges with caution — it usually means fewer senior hours on your project, or costs pushed into change requests later.

GST: what changed in 2025, and what did not

India's GST system was restructured under GST 2.0, effective from 22 September 2025, which simplified the old four-slab structure. It is worth checking this directly because many business owners assume software got cheaper as a result — it did not. GST on software services did not change when GST moved to two main slabs on 22 September 2025, so software and IT services stay at 18%. This applies regardless of how the software is delivered: software services attract 18% GST when the customer is in India, and 0% when the service is exported under a Letter of Undertaking (LUT).

For budgeting purposes, build 18% into every domestic quote you receive, on top of the development fee. If you are GST-registered, you can generally claim input tax credit on this, which offsets some of the cost against your own output tax liability — but factor the cash-flow impact of paying it upfront. Custom builds, web and app development specifically fall under SAC 998314 for GST classification purposes, which is useful to know when checking an invoice is correctly coded.

Fixed price or time-and-material: which suits your budget

Most Indian vendors offer two contract structures, and the choice affects how predictable your budget is.

Fixed price suits a well-defined scope — you know roughly what screens, features and integrations you need, and you want cost certainty. The trade-off is that any change after signing becomes a formal change request, usually at a premium, and vendors tend to pad fixed quotes to cover their own risk.

Time-and-material (T&M) suits projects where requirements will evolve, such as a new product finding its market fit. You pay for actual hours worked, which is fairer if scope shrinks, but your final bill depends on discipline — both yours in controlling scope creep, and the vendor's in reporting hours honestly. For first-time buyers without an in-house technical lead, a hybrid is often safest: fixed price for a clearly scoped first phase (discovery and MVP), then T&M for ongoing iteration once you have a working product and better visibility of what comes next.

The costs most budgets leave out

The biggest source of budget overrun is not the development fee itself — it is everything around it. A few items to add to your worksheet before you compare vendor quotes:

  • Discovery and requirements work. Most buyers underestimate discovery costs, typically ₹1.5–4 lakh before a single line of code is written. Vendors who skip this and jump straight to a fixed quote are usually guessing at scope.
  • QA and testing. A healthy budget allocates a meaningful share of the project to testing rather than treating it as an afterthought; quotes with little or nothing allocated here tend to ship more bugs.
  • Ongoing maintenance. Once live, software needs patching, hosting and minor updates. Organisations should typically budget between 15% and 25% of the original custom software development cost annually to cover ongoing maintenance, security patching, dependency updates, and minor feature iterations.
  • Hosting and infrastructure, which scales with your user numbers and is easy to underestimate if you only priced the initial server tier.
  • A contingency buffer. Even well-scoped projects run into surprises — unclear third-party API documentation, data migration issues, or a feature that proves harder than expected. Ten to fifteen percent of the project budget set aside as contingency avoids a crisis when this happens.

A short checklist before you request quotes

  1. Write down your core workflow and the three or four features that genuinely matter for launch — resist the urge to list everything you might want eventually.
  2. Decide whether you want a fixed-price first phase or a T&M engagement, and say so in your request for proposal.
  3. Ask every vendor to itemise discovery, design, development, QA, deployment and the first three months of support separately, so quotes are comparable.
  4. Confirm GST treatment and payment milestones in writing before signing.
  5. Set aside 15–25% of the build cost annually for maintenance, and a one-time contingency of 10–15% on top of the quoted price.

Conclusion

Budgeting a software or app project in India is less about finding the cheapest hourly rate and more about pricing the whole lifecycle — discovery, build, tax, launch and the year of maintenance that follows. A clear scope, the right contract type for your situation, and a realistic contingency will save more money than chasing the lowest quote.
