Software Development Company Serving Kolkata Businesses
Kolkata trade, logistics, and professional-service firms often run on long-standing processes and mixed tools. Unitas builds practical custom software from Pune—portals, internal apps, and integrations—in IST. We do not claim an east-India branch office.
Software Development Services for Kolkata Businesses
Services we actually deliver—not a keyword list.
Web Application Development
React and ASP.NET Core applications, secure APIs, and database-driven systems that your team can actually run day to day.
Mobile App Development
iOS, Android, and cross-platform apps for field teams, customers, and internal operations—connected to the same backend as your web systems.
API & System Integration
ERP, CRM, accounting, payments, and third-party APIs connected so data stops living in separate silos.
Legacy Application Modernization
Phased modernization of older .NET applications, APIs, frontends, and databases—without a reckless full rewrite.
Problems We Help Kolkata Businesses Solve
- Order and consignment status living in email and registers
- Accounts and operations never looking at the same data
- Family-run groups with several entities and no shared system
- Vendor communication stuck on phone calls
- Legacy applications with no documentation
Software We Build for Kolkata Teams
Trade and operations software
Order, status, and reporting tools that match how Kolkata firms actually move goods and jobs.
Portals
Customer or vendor login for documents and status.
Modernization
Phased replacement or API wrapping of systems that still run the business.
Industries
Only sectors we can support with real delivery.
Trade and logistics
Tracking and exception handling for east-India distribution patterns.
Professional services
Intake and delivery systems for Kolkata firms.
Multi-entity groups
Internal tools that respect how the group is actually structured.
Kolkata Use Cases
From register to shared status
Office and warehouse seeing the same consignment or job state.
Customers who are not in Kolkata
A portal so status is not a phone call to one person.
Why Work With Unitas
Unitas IT Solutions serves Kolkata businesses from our Pune office—not a claimed Kolkata storefront. Work happens in IST, with named owners, sprint demos, and documented progress so stakeholders stay in control.
Typical stack when it fits the project: ASP.NET Core, C#, React, SQL Server, Entity Framework Core, and REST APIs. We choose technology based on the system, not a sales list.
