Custom Software, CRM and SaaS Built Around How You Work
TENSIX builds custom business software: back-end systems, internal tools like CRMs and ERPs, and complete SaaS products (software you sell online by subscription). Prices are fixed From ₹75,000, and you own all the source code from day one.
What is custom SaaS and enterprise software engineering?
Custom SaaS and enterprise software engineering is the practice of developing multi-tenant, cloud-native business platforms on distributed edge infrastructure with decoupled serverless APIs. Replacing monolithic PHP frameworks with static edge clients and direct database microservices, it ensures sub-400ms global latency, zero database connection pool lockups, and 100% proprietary code ownership without recurring licensing penalties across Ahmedabad's commercial corridors.
Why Monolithic Agency Software Stalls High-Load Workflows
Benchmarked against 50 IT and SaaS firms across Prahladnagar, S.G. Highway, and Navrangpura. While legacy agencies deliver bloated server-rendered codebases, TENSIX ships deterministic edge systems with zero database bottlenecks.

Common questions
How much does it cost to build a SaaS MVP or custom software in Ahmedabad?
Fixed-price SaaS MVP platforms start from ₹75,000 ($1,000+) and are typically delivered in 14 to 21 business days, including authentication, payment gateway integration (Razorpay/Stripe), database schema, and mobile-responsive dashboards. Larger enterprise CRMs and ERPs are scoped from ₹1,25,000+ ($1,650+) with guaranteed fixed milestones.
How are milestone payments structured?
To keep the process transparent and low-risk, projects are divided into milestone stages: 40% upfront to initiate architecture, 30% upon interactive staging demo review, and the final 30% only after full production deployment, testing, and handover on your own servers.
Why custom software instead of ready-made software?
Ready-made software is quick to start but forces you to change your workflow to fit its limitations, and subscription fees grow exponentially as you add employees. Custom software fits your exact business process, and because you own all the source code, there are zero per-seat licensing fees.
Who owns the code and intellectual property?
You do, 100% from Day 1. The source code is maintained directly inside your own private repository and runs on your cloud accounts (AWS, Oracle, or VPS). You receive all keys and credentials, so you are never locked in to TENSIX.
Can it connect to Tally, WhatsApp or my existing ERP?
Yes. We integrate custom software with external tools through webhooks, REST APIs, or automated sync scripts (including WhatsApp notifications, Tally XML/API sync, and payment gateways). We verify integration feasibility on the first scoping call before you pay anything.
What happens after launch? Will I need you forever?
No lock-in. Every delivery includes comprehensive architecture documentation and video walkthroughs so your internal team or any outside engineer can maintain it. If you prefer ongoing support, we offer monthly retainer plans for continuous feature development and server monitoring.
