The Bottleneck
Why generic boxed software limits growing companies
Subscription software feels cheap initially, but costs thousands monthly in seat licenses while forcing your team to manage work in spreadsheets. Custom software gives you an unfair operational advantage.
Boxed & generic software traps
- Expensive per-seat monthly license fees that scale with team size
- Rigid workflows forcing you to change how you operate
- Data locked inside third-party closed ecosystems
- Painful, incomplete integrations that break constantly
- Paying for dozens of bloated features your team never uses
- Zero proprietary IP or valuation added to your business

Questions
Frequently asked questions about custom software
Important answers regarding pricing, code ownership, integrations, and long-term support.
The investment depends on scope, complexity, integrations, and user roles. A focused operational tool or customer portal usually ranges between ₹2.5L–₹6L, while an enterprise ERP or multi-tenant SaaS platform ranges from ₹8L–₹25L+. We provide fixed-price milestone estimates after an initial discovery workshop.
You own 100% of the code, database schemas, and intellectual property. Unlike SaaS platforms where you rent software, custom software is a proprietary corporate asset that belongs completely to your company.
Yes. We specialize in building bi-directional integrations with third-party software, including accounting systems (Tally, QuickBooks, Zoho Books), CRM software, payment gateways, and custom hardware scanners.
A minimum viable product (MVP) or initial module usually ships in 6–8 weeks. Full-scale enterprise software deployments typically take 12–16 weeks with phased module releases so your team gets value immediately.
We provide warranty periods, comprehensive video training for your staff, server monitoring, security updates, and optional ongoing SLA maintenance packages.
