How much does custom software development cost in India?
Software has no single price. Cost follows scope, complexity, integrations and how you buy the team. Here is what moves the number, what is often forgotten, and how to get an estimate you can trust. We use Stack18’s own published pricing model and say when a ready-made system is the cheaper route.

How much does custom software cost in India?
There is no honest price without a scope. Custom software cost depends on features, integrations, compliance needs, platforms and the pricing model you choose. At Stack18 you start with a fixed-price discovery of 1 to 4 weeks, which produces a written scope and a fixed price for the build. If a ready-made system fits, editions start from ₹1.6L, one-time.
Six drivers decide most of the cost.
Change any one of these and the estimate changes. Knowing them lets you compare quotes fairly.
| Driver | Why it changes the cost | How to keep it under control |
|---|---|---|
| Scope and features | Every screen, role and workflow adds design, build and testing effort. | Launch with the smallest useful version, then add in phases. |
| Integrations | ERP, GST, payment, WhatsApp and logistics connections each need building and testing. | List the systems that must connect on day one and defer the rest. |
| Compliance and security | GST, audit trails, role-based access and data rules add work. | State compliance needs up front rather than discovering them mid-build. |
| Platforms | Web only, web plus Android and iOS, or offline use for field teams. | Pick the platform your users actually use first. |
| Data migration | Moving history from Tally, Excel or an older system takes cleaning and mapping. | Decide what history genuinely needs to move. |
| Team model | A fixed project, a time-and-materials engagement and a dedicated team behave differently. | Match the model to how well the scope is defined. |
Three ways to pay for the same software.
Each pricing model suits a different level of certainty. Our fixed price vs time and materials guide goes deeper.
Fixed price
- Best when
- The scope is defined and you want to know the cost before you start.
- Trade-off
- Changes outside the agreed scope are estimated separately.
- Typical result
- A written scope, timeline and price agreed after discovery.
Time and materials
- Best when
- The scope will evolve and you want flexibility.
- Trade-off
- The final cost is open-ended unless you set a cap.
- Typical result
- Pay for the effort used, with regular reviews.
Monthly team
- Best when
- You have an active roadmap and ongoing releases.
- Trade-off
- A continuing monthly commitment, not a one-off project.
- Typical result
- A steady team and regular releases.
Four costs that rarely appear in the first quote.
A quote for the build is not the cost of owning the software.
Hosting and infrastructure
Servers or cloud accounts run every month after launch, and grow with usage.
Third-party usage
WhatsApp messaging, payment gateways and SMS are charged by the provider, not the developer.
Support and improvement
Software needs patches, monitoring and changes. Stack18’s optional Care plan starts from 15% of build value per year.
Training and adoption
Staff need to learn the system. Budget time for training and a few weeks of hypercare.
Check whether you need to build at all.
If your processes are mostly standard, a ready-made system can cost less and go live sooner. Stack18’s six solutions are priced once, in rupees, from ₹1.6L with no per-user fees, and can be customised. If nothing fits, we say so and scope a custom build instead.
Five things to prepare before you ask for quotes.
Quotes are only comparable when they answer the same brief.
Write the goal
One paragraph on the problem and the outcome you want.
List the users
Who uses it, on which devices, and how many.
Name the integrations
Which systems must connect, and which can wait.
Set a timeline
The date you need it live, and why.
Ask what is excluded
Hosting, third-party fees, support and changes beyond scope.
Common questions.
How much does custom software development cost in India?
It depends on scope, integrations, compliance, platforms and the pricing model. Stack18 does not quote without a scope: a fixed-price discovery of 1 to 4 weeks produces a written scope and a fixed price for the build.
Is fixed price or time and materials cheaper?
Neither is always cheaper. Fixed price gives certainty when the scope is clear. Time and materials suits evolving scope but leaves the final cost open unless capped.
How long does custom software take to build?
Stack18 projects typically run 4 to 16 weeks after a 1 to 4 week fixed-price discovery, depending on scope. Larger programmes run longer or continue as a monthly team.
What costs come after launch?
Hosting, third-party usage such as WhatsApp or payment gateways, support and improvement, and training. Stack18 includes 30 days of hypercare after go-live.
Can a ready-made system replace custom software?
Often, when your processes are mostly standard. Stack18’s ready-made solutions start from ₹1.6L one-time with no per-user fees, and can be customised where you differ.
Does Stack18 charge per user?
No. Stack18’s ready-made solutions have no licence or per-user fees. Hosting on your own cloud account and third-party usage are paid separately.
