"How much does custom software cost?" has the same answer as "how much does a building cost" — it depends entirely on what is inside it. But the ranges are knowable, and the things that move the number are consistent. This guide gives you both, so you can read a quote instead of just comparing totals.
Realistic 2026 ranges in India
| Project type | Range | Typical timeline |
|---|---|---|
| Single-workflow internal tool | ₹3L–₹8L | 4–10 weeks |
| Departmental system (sales ops, inventory, service desk) | ₹6L–₹15L | 2–4 months |
| Custom ERP, multi-module | ₹10L–₹35L | 4–9 months |
| Multi-tenant SaaS product | ₹12L and up | 4 months and up |
| Enterprise platform with integrations and compliance | ₹25L and up | 6 months and up |
These assume senior engineers, a written scope, testing, and code you own. Quotes far below these bands are usually a template, a junior team, or a scope that will be renegotiated after you have paid the advance.
What actually moves the number
User roles. The most underestimated multiplier. Each additional role is its own interface, permission model, and test surface. Three roles is not one system with extra menus — it is close to three systems sharing a database.
Integrations. Talking to a modern system with a documented API is days. Talking to a legacy system with no API — an old accounting package, a machine controller, a government portal — can cost more than the rest of the build combined. Identify every integration before anyone quotes.
Data migration. Moving years of records out of spreadsheets and legacy systems, cleaning them, and reconciling them is real, unglamorous work that routinely takes 10–20% of a project. It is also the most common reason a go-live slips.
Compliance and audit requirements. Audit trails, e-signatures, retention rules, and role separation are engineering work, not settings. If you are in a regulated sector, say so on the first call — retrofitting compliance costs multiples of building it in.
Performance at your real data volume. A system designed for 10,000 records and deployed against 5,00,000 will be slow, and fixing it later means redesigning queries and indexes under production pressure. Ask what volume the design assumes.
Scale and availability. "It should never go down" is a budget decision. Redundancy, backups, and monitoring are worth buying — just know you are buying them.
Team models and what they mean for you
| Model | Cost shape | Best for |
|---|---|---|
| Fixed price, scoped | Fixed, with a written scope | Well-understood projects |
| Time and materials | Monthly rate | Evolving scope, longer builds |
| Dedicated team | Monthly per engineer | Ongoing product work |
Fixed price is safe only when the scope is written down. An unscoped fixed price means the vendor priced the uncertainty into your number and will still argue about changes. Time and materials without a cap is the opposite risk. A scoped fixed price for phase one, then time and materials for evolution, is the arrangement that fails least often.
The recurring costs
- Hosting and infrastructure — a few thousand rupees a month for an internal tool, more for anything customer-facing
- Maintenance and support — plan 15–20% of build cost per year; libraries, OS versions, and browsers move whether or not you do
- Third-party services — payment gateways, SMS and OTP, mapping, email delivery, all metered
- Enhancements — the requests that arrive once people start using it, which is a sign of success, not scope creep
A vendor who never mentions year two is either inexperienced or counting on you not to ask.
How to compare quotes fairly
Get every vendor to quote against the same written scope document, itemised by module and role, with an explicit out-of-scope list. Then compare like for like. Without that, you are comparing three different interpretations of a two-line brief, and the lowest number is simply the vendor who understood the least.
Also compare what you own at the end. A cheaper quote where the vendor keeps the code and hosts it on their account is not cheaper — it is a subscription with an upfront fee.
Where budgets leak
- Verbal scope changes that never get priced
- Skipping discovery to "save time", then rebuilding in month three
- Signing off design after development has started
- No staging environment, so testing happens in production
- No data-migration plan until go-live week
- No named decision-maker on your side, so approvals stall and the team idles
Four of those six are on the buyer's side. The single most effective thing you can do to control cost is to name one internal owner with authority to decide.
Before you spend, check you need it
Custom software earns its budget when your workflow is your edge, when integration is the real problem, or when licensing has crossed over. Otherwise buy — see custom vs ready-made software. If you are not yet sure what to build, start with IT consulting, where the deliverable is a decision and a scope. If the pain is manual repetition, business automation is usually cheaper and faster. And if systems simply do not talk to each other, that is digital transformation in Indore.
Get a written scope before a number
We scope first and quote second, itemised, with the out-of-scope list written down. If we think you should buy off the shelf instead, we will say so.
