How We Build Custom Software
01
Discovery & Scoping
We map your workflows, define every feature, and identify every integration. A detailed specification document is agreed before any code is written.
02
Architecture Design
Database schema, API design, infrastructure choices, and security model — all documented and reviewed before development starts.
03
Agile Development
Two-week sprints with demo sessions at each milestone. You see working software throughout — not a big reveal at the end.
04
QA & Testing
Automated test suites, security reviews, load testing, and UAT with your team before anything touches production.
05
Launch & Support
Staged rollout, monitoring setup, team training, and a 60-day post-launch hypercare period — included on every project.
Custom Software for Every Use Case
// Lead pipeline — auto-scored by AI
const lead = await scoreLead({
source: 'website_form',
score: aiScore(formData)
});
CRM & Sales Tools
Custom CRM & Lead Management Systems
Generic CRMs like HubSpot and Salesforce are built for average businesses. We build CRMs that match exactly how your sales team works — your pipeline stages, your lead scoring logic, your integrations, your reports.
Custom pipeline stages and deal workflows
AI-powered lead scoring and routing
WhatsApp and email integration
Role-based access and approval workflows
Custom dashboards and revenue forecasting
// Invoice auto-processing pipeline
await processInvoice({
extract: ocrExtract(pdf),
approve: threshold < 50000
});
Operations & ERP
Operations Platforms & Internal Tools
The software your team uses every day to run the business — inventory management, order processing, invoice automation, vendor portals, and HR systems. Built to eliminate manual work and integrate with your existing stack.

Why Novatex for Custom Software
01
Specification Before Code
We document every feature, every user role, and every integration before writing a line of code. This eliminates the scope creep and budget overruns that kill most software projects.
02
Fixed-Price Projects
We quote fixed prices based on agreed specifications. You know the cost before we start. No hourly billing surprises, no change orders for features that were always in scope.
03
Full-Stack In-House Team
Frontend, backend, database, DevOps, and QA — all in-house in Kolkata and Bangalore. No subcontracting, no communication delays across time zones.
04
You Own Everything
All source code, databases, and infrastructure are yours from day one. No vendor lock-in, no licensing fees, no hostage-taking. If you want to move to another team later, everything transfers cleanly.
05
Built to Scale
We architect for growth from the start. The system we build for 100 users handles 10,000 users without a rewrite — because we design for load, not just for demo day.
06
On-Time Delivery
40+ projects delivered. We have a track record of on-time delivery because we scope precisely, milestone clearly, and flag risks early rather than discovering them at go-live.

When Should You Build
When Should You Build
Custom Software?
Custom software makes sense when off-the-shelf products either don't exist for your use case, require so many workarounds that they create more friction than they solve, or cost more in licensing fees and lost productivity than a custom build would cost over three years. The decision is almost always economic — and often closer than businesses assume.
The most common trigger we see is a business that has outgrown its tools. They're running operations on spreadsheets, using three disconnected SaaS products that don't talk to each other, and spending significant team time on manual data entry between systems. At that point, a custom platform that does exactly what those three tools do — integrated, automated, and built around their workflow — typically pays for itself within 12–18 months.
The Specification Is Everything
The most common reason custom software projects fail — over budget, over time, or simply not fit for purpose — is inadequate specification. When requirements are vague, developers build what they think you mean. When scope isn't locked, features expand indefinitely. When integrations aren't mapped upfront, they become expensive surprises mid-project.
Our process starts with a detailed specification document — every screen, every user role, every workflow, every integration, every edge case. This document is reviewed, challenged, and agreed before any code is written. It adds two weeks to the start of the project and saves months of rework at the end.
Build for India and the UAE
Software built for the Indian and UAE markets has specific requirements that generic templates don't address — GST compliance and invoice formats for India, VAT and e-invoicing mandates for UAE, multi-currency handling, Arabic right-to-left UI support, WhatsApp Business API integration for customer communication, and UPI/Razorpay payment processing. We build these in as standard rather than bolt-ons. The result is software that works correctly in your market from day one rather than requiring expensive retrofitting later.
Every Project is Different
We don't publish software project pricing because scope is everything. A 3-screen internal tool and a 50-module enterprise platform are both "custom software" — the price difference is tenfold. We quote based on agreed specification, not guesswork.

Custom Software FAQs
How much does custom software cost?
It varies significantly by scope. A focused internal tool with 3–5 screens typically starts from ₹3–5 lakhs. A mid-size platform with multiple user roles, integrations, and a custom admin system is typically ₹10–30 lakhs. An enterprise platform with complex workflows, third-party integrations, and mobile app is ₹50 lakhs+. We give fixed-price quotes after scoping — so you know the exact number before committing.
How long does it take to build?
Timelines depend on scope. Simple internal tools take 6–10 weeks. Mid-size platforms with multiple modules typically take 3–5 months. Complex enterprise systems are 6–12 months. We agree a milestone-based timeline at project kickoff, and build it into the contract. Our track record across 40+ projects shows on-time delivery in 90%+ of engagements.
Do we own the source code?
Yes — unconditionally. All source code, database schemas, infrastructure configurations, and documentation are transferred to you on project completion. There is no licensing fee, no vendor lock-in, and no restrictions on what you do with the code. You can hand it to any other development team at any time.
Can you integrate with our existing systems?
Yes. We integrate with most business systems — Tally, SAP, QuickBooks, Salesforce, HubSpot, Zoho, WhatsApp Business, payment gateways, shipping providers, and custom APIs. We map every integration during the scoping phase and include the integration cost in the fixed-price quote. There are no integration surprises mid-project.
What happens after the software is launched?
Every project includes a 60-day post-launch hypercare period covering bug fixes, performance monitoring, and minor adjustments at no extra cost. After hypercare, we offer monthly maintenance retainers covering security updates, dependency management, hosting management, and priority support. Retainers start from ₹20,000/month depending on system complexity.
Can you build software that works in India and UAE?
Yes — and this is a specific strength. We build multi-region systems with Indian GST compliance, UAE VAT/ZATCA compliance, multi-currency support, Arabic RTL UI support, and region-specific payment gateways (Razorpay for India, network cards for UAE). We've built several platforms that operate across both markets simultaneously.
Do you build mobile apps as well as web software?
Yes. We build React Native mobile apps (iOS and Android from one codebase) alongside web platforms, and often design them as part of the same project with a shared backend API. If your use case requires a field team, customer-facing app, or offline capability, we scope the mobile component as part of the overall system rather than as a separate project.
How do you handle data security?
Security is built into architecture from day one — not retrofitted. This includes role-based access control, encrypted data at rest and in transit, secure API authentication (JWT + refresh tokens), audit logging, and regular dependency security scans. For projects handling sensitive data (financial, medical, legal), we conduct formal security reviews and penetration testing before launch.
What if our requirements change during the project?
Minor refinements within the agreed specification are handled without additional cost — that's normal in any build. Significant new features or scope changes are assessed against the specification, quoted, and approved before work starts. We don't surprise you with change order bills; we flag the impact of any change before implementing it.
