Web applications we have built for businesses across India

Every project starts with a real operational problem. Here is what each client needed to fix, and what the application does for their business today.

An inventory and order system that replaced the spreadsheets

Client Name · Distribution

An inventory and order system that replaced the spreadsheets

  • Web App
  • Inventory
  • Role-Based Access
  • Reports
Challenge

Stock, orders and invoices lived in separate spreadsheets. Errors crept in, and nobody could see live stock without calling the warehouse.

Solution & Outcome

A custom web application with live stock, order tracking, GST-ready invoices and role-based logins. Teams now work from one source of truth and managers get reports on demand.

A client portal that answers status questions before they are asked

Client Name · Services

A client portal that answers status questions before they are asked

  • Client Portal
  • Dashboard
  • Notifications
  • PHP / MySQL
Challenge

Clients kept calling and emailing for updates on their work. The team spent hours every day on status follow-ups instead of the work itself.

Solution & Outcome

A secure portal where clients log in, track progress, download documents and raise requests. Automated email and WhatsApp updates keep everyone informed without manual effort.

A booking platform built to handle growing demand

Client Name · Marketplace

A booking platform built to handle growing demand

  • Booking Engine
  • Payments
  • Admin Panel
  • API
Challenge

Bookings came in by phone and chat, with double bookings and no payment tracking. The business could not grow without adding more staff.

Solution & Outcome

An online booking platform with real-time availability, secure payments and an admin panel. Customers book and pay on their own, and the team manages everything from one dashboard.

A multi-user SaaS platform built from the first idea

Client Name · Software / SaaS

A multi-user SaaS platform built from the first idea

  • SaaS
  • Subscriptions
  • Analytics
  • Cloud
Challenge

A founder with a clear idea and no technical team. The product needed accounts, plans and billing, and a base that could grow with the user count.

Solution & Outcome

We planned the product, built an MVP with user accounts, subscription billing and an analytics dashboard, then iterated with real user feedback. The platform is hosted for growth from day one.

Our Process

A clear process from first call to go-live

Six simple steps, the same on every project. You always know what is being built and what comes next.

Get Started

  1. Discovery & Requirements

    We learn your workflow, users and goals in a free call, then agree on scope, features, timeline and budget.

  2. Architecture & Planning

    We plan the database, modules, user roles and integrations, and choose a tech stack that can grow with you.

  3. UI/UX Prototype

    Clickable prototypes for desktop and mobile. You test the flow and approve it before any code is written.

  4. Agile Development

    We build in short sprints with a working demo at each stage, so you can review progress and give feedback early.

  5. Testing & Deployment

    Functional, security and load testing, then a smooth launch on secure cloud hosting with data migration handled.

  6. Support & Scaling

    Team training, monitoring, maintenance and new features as your users and business grow.

What you get with every web application

No off-the-shelf shortcuts and no surprises. Every project ships with the design, the build and the support below, and the code and data are yours to keep.

FAQ

Questions? We have answers.

Everything people ask before starting a web application project. Cannot find your question? Send us the form and we will reply within one working day.

A website mainly shares information, while a web application lets users do things: log in, enter and manage data, place orders, make bookings or view reports. Examples include customer portals, inventory systems, booking platforms, dashboards and SaaS products. It runs in the browser, so there is nothing to install.

The cost depends on the number of features, user roles, integrations and the amount of custom design and logic. After a free discovery call we send a written scope and a fixed quote, so there are no surprises. Use the budget slider in the form to tell us your range.

A focused first version (MVP) often takes 6 to 12 weeks. Larger systems with many modules and integrations take longer. We agree on a timeline before we start and share a working demo at the end of each sprint.

We choose the stack to fit your project, commonly PHP and MySQL for business applications, with modern JavaScript on the front end and REST APIs for integrations. We explain the choice in plain language during planning, so you are never locked in.

Yes. We first review the current code, database and user flows. Then we recommend whether to improve, refactor or rebuild, and plan the move so your data is migrated safely and your team can keep working.

Security is built in from the start: encrypted connections, secure logins, role-based access, input validation and regular backups. Before launch we test for common vulnerabilities and set up the server properly.

You do. Source code, designs, database, domain and hosting logins are handed over to you at the end of the project.

Every project includes a free post-launch support period for bug fixes and questions. After that you can continue with a monthly maintenance plan covering updates, backups, monitoring, security and new features.
