Why is there no single price for custom software?
Custom software is built for one business, so its cost depends on what that business needs. A booking portal for a single clinic and a multi-branch hospital platform both count as "healthcare software", but one may need a few weeks of work from a small team and the other many months from several teams.
Any honest estimate is calculated the same way: the effort needed to design, build, test and launch the scope, multiplied by the rate of the people doing it. When two quotes differ widely, it is almost always because the vendors have assumed different scope, a different team or different quality standards — not because one has found a cheaper way to write the same code.
How is a software estimate calculated?
Most Indian development companies estimate in person-weeks or person-months. They break the scope into features, estimate the effort for each, add time for design, testing, project management and deployment, and multiply by the rate for each role. A simple way to sanity-check any quote:
- Team: which roles are included — product manager, designer, frontend, backend and mobile engineers, QA, DevOps?
- Duration: how many weeks each person works on the project, not just the calendar length of the project
- Seniority: the mix of senior, mid-level and junior people, which changes both the rate and the speed
- Contingency: how much buffer is included for unknowns, and how changes in scope will be priced
- Exclusions: what is not in the price, such as content, third-party licences, hosting or app store fees
What makes custom software cost more?
The biggest cost drivers are the ones that multiply work across the whole product. Watch for these when you write your requirements:
- The number of user roles and apps — a customer app, a staff app and an admin panel are three products sharing one backend
- Integrations with payment gateways, ERPs, CRMs, accounting or logistics systems, especially older ones with poor documentation
- Complex business rules, approvals, pricing logic or reporting that must match how your teams work today
- Data migration from spreadsheets or a legacy system, including cleaning and validating that data
- Security and compliance needs such as audit logs, single sign-on, data residency, DPDP Act or GDPR requirements
- Performance and scale targets — supporting thousands of concurrent users is a different design from supporting fifty
- Platforms: web only, mobile only, or web plus iOS and Android
How long does it take, and how does time relate to cost?
Timeline and cost are linked, but adding people does not shorten a project in a straight line. Larger teams need more coordination, and some work has to happen in sequence. As a guide, a business website usually takes 3–8 weeks, an MVP for a SaaS product 8–14 weeks, a first mobile app release 8–16 weeks, and an enterprise system such as an ERP is delivered in phased releases over several months.
If a deadline is fixed, the realistic levers are scope and team size. Cutting testing or design time to hit a date usually costs more later, when defects and usability problems have to be fixed in production.
Fixed price, dedicated team or hourly — which is cheaper?
A fixed-price project suits a well-defined scope: you know the total cost before work starts, and the vendor carries the risk of estimating it correctly. Because of that risk, fixed prices include contingency, and changes in scope are priced separately.
A dedicated team billed monthly suits products whose roadmap will change as you learn from users. You pay for capacity rather than a fixed list of features, which is often cheaper overall for evolving products. Hiring individual developers by the hour or month suits companies that already have a technical lead and need extra hands or specific skills.
None of these models is cheaper in every case. Choose the one that matches how certain your requirements are.
What costs continue after launch?
Software is never finished. Plan a yearly budget for cloud hosting and third-party services, security updates and dependency upgrades, monitoring and bug fixes, and new features based on user feedback. Mobile apps also need updates when Apple and Google release new operating system versions. Agree a support and maintenance plan with your vendor before launch so these costs are predictable.
How do you keep the budget under control?
A few practices make the biggest difference:
- Start with a discovery sprint to agree scope, architecture and a written estimate before the main build
- Define the smallest first release that solves a real problem for real users, and ship it
- Prioritise features by business value, and keep a written list of what is out of scope
- Ask for weekly demos and repository access, so you see progress and can change course early
- Make sure you own the code, designs, cloud accounts and documentation from day one
