Custom Application Development

When off-the-shelf software doesn't fit your processes — complex pricing, multi-entity accounting, industry-specific workflows — we build applications shaped around how your business actually operates.

The founders and senior consultants scope every engagement. You explain your business once, to people who understand it.

Mobile Apps

Mobile App Development

30+ mobile apps in production — for field sales, warehouse workers, farmers, students, HR self-service, and dealer networks. Not prototypes. Apps people use every day to get work done.

We build for Android, iOS, and cross-platform (Flutter). Every app connects to the backend business system — attendance syncs with payroll, dealer orders flow into ERP, field data feeds dashboards.

Legacy Modernisation

Legacy Application Modernisation

Still running VB6, VB.NET, or desktop applications from the 2000s? We've been there — we modernised our own products. Sahaj Accounting and Sahaj Payroll both migrated from VB.NET to .NET Core. We know the risks, the data migration challenges, and how to do it without disrupting your operations.

Your business logic is valuable. We don't throw it away — we move it to modern, web-based, cloud-ready architecture.

Proven migrations

CSE Centre for Science & Environment
Contact and visitor management system — migrated from legacy desktop to .NET Core web application
OWN PRODUCT Sahaj Payroll → .NET Core
VB.NET desktop payroll to modern .NET-based web payroll — serving 700+ businesses
OWN PRODUCT Sahaj Accounting → .NET Core
VB.NET to .NET Core — complete rewrite preserving 25+ years of accounting logic

"We migrated our own products first. That means we've already solved every problem your legacy app will throw at us."

AI & Automation

AI-Powered Business Tools

AI that solves real business problems — not demos, not experiments. Document processing that reads invoices. Forecasting that predicts demand. Chatbots that answer your customers. Built on top of the business systems we already understand.

Infrastructure & Managed Services

Application Hosting, Cloud Infrastructure & Managed Services

Your application needs more than code — it needs infrastructure that stays up. We provide end-to-end managed hosting on AWS, Microsoft Azure, Google Cloud, or partner datacentres. Our infrastructure team handles everything: server provisioning, application deployment, monitoring, backups, SSL, security — so you focus on running your business.

Already have a website or application hosted elsewhere? Migrating to better infrastructure? We manage third-party applications, legacy systems, and websites — you don't need to rebuild. Just hand it over.
