Software that runs in the browser, built to your scope, in accounts you own.

In short

In a web app, users log in and get something done: they enter data, book, quote or manage records. We scope it with you, build it in weekly steps, and hand over code and accounts in your name.

How we work

  1. 01

    Tell us the goal

    A rough note through the form on what you sell and what needs to change.

  2. 02

    We study your market

    How people find you today, where inquiries get lost, then a call in your working day.

  3. 03

    A written plan

    The work, who does it and how it is measured. Nothing starts until you approve it.

  4. 04

    The work starts

    Our team in India does the work, with calls set in your working hours.

  5. 05

    Reports and visits

    Every number we report shows its source and date range, and we travel to our clients every 3 to 4 months.

Common challenges

Signs you need a web app

Typical situations, not results from a named client.

The business runs on spreadsheets

Several people edit the same files, and nobody trusts the numbers.

Customers call for updates

A portal where clients check orders, bookings or documents saves calls on both sides.

Off-the-shelf tools almost fit

You pay for three tools and still copy data between them by hand.

You have a product idea

A software product for your market, starting with the smallest version that people will pay for.

How we work

How a web app project runs

  1. 01

    Scope

    We write down the users, features, data and integrations, and what is out, for you to approve.

  2. 02

    Design

    Flows and screens are agreed before any code.

  3. 03

    Set-up in your accounts

    The repository, hosting and test site are created in your name.

  4. 04

    Weekly builds

    Each week ends with something you can click on and comment on.

  5. 05

    Test and launch

    We test odd cases, browsers and phones, then launch with you.

What a web application development company does

A web application development company builds software that runs in a browser: logins, forms, data, workflows and reports. Unlike a website, a web app is used to get work done, so the scope, the data and the security matter more than the look.

We check builds against common risks such as those in the OWASP Top 10, the standard list of the most critical web application security risks. For Canadian clients, Ontario's AODA requires WCAG 2.0 Level AA on public websites of organisations with 50 or more employees, so we design and build to that level.

An example we can show in full is DesiMachines (desimachines.com), a construction equipment research site for buyers in India, which we designed and developed for Desi Machine Pvt. Ltd. Its machine finder, compare tool, cost calculators and owner reminders run as in-page apps on WordPress and WooCommerce, with sign-in by one-time code on a mobile number, WhatsApp messages, and English and Hindi versions. It serves the Indian market only.

Cost

What web application development costs

There is no public price list, because the cost follows the job.

What affects the cost

  • How many users, roles and features
  • How many systems it connects to
  • How much design work comes first
  • Support needs after launch

How we price

Hosting and third-party service fees are separate, and we estimate them before you commit. You see the scope and the fee in writing before work starts.

Questions buyers ask us

  • It scopes, designs, builds, tests and supports software that runs in a browser, such as customer portals, dashboards, booking tools, internal systems and SaaS products.

  • A website mostly gives information. A web app lets people log in and do something: enter data, book, quote, pay or manage records.

  • Scoping, UI/UX design, front-end and back-end development, integrations, testing, launch and support after launch.

  • You should.

  • Yes. Most web apps connect to tools you already use, such as your CRM, payment provider or ERP, through their APIs.

  • Yes. Scoping and reviews run on video calls in your working hours, and weekly builds let you see progress. We travel to our clients every 3 to 4 months, and we are available round the clock, 24x7, as per your location.

    How to build a web app: from idea to launch

    Most web apps that fail do so before a line of code: the problem was vague, the first version tried to do everything, or nobody decided who the users were. Building one well is mostly a matter of doing the steps in order. This guide walks through the eight steps from idea to a running product, what each one produces, and where AI tools fit. It is part of our guide to web apps and mobile apps.

    Progressive web app vs native app: which to build

    Not every app needs the App Store. A progressive web app is a website built to behave like an app: it installs to the home screen, works offline and can send notifications, from one codebase. A native app is built for each platform and installed from the stores. This guide compares the two on what they can do, how they are distributed and updated, and what they cost, from the platforms' own documentation, and says which to build when. It is part of our guide to web apps and mobile apps.

    SaaS vs custom software: buy, build or both

    Every business runs on a mix of bought software and its own processes, and sooner or later the two collide: the CRM almost fits, the spreadsheet workaround grows, the subscription bill climbs with every new hire. The question becomes whether to keep buying, build something of your own, or combine the two. This guide compares SaaS and custom software on cost over five years, speed, fit, control, data and integrations, and sets out when each makes sense. It is part of our guide to web apps and mobile apps.

  • Costs

    Travel website development cost: booking, search and payments

    Travel website development cost is quoted as a number by people who have not yet asked what the site must do, and the answer changes by an order of magnitude depending on whether it shows tours, books them, or searches and books them across other people's inventory. This guide gives the method instead: five drivers that set the hours, public wage data for what the hours cost, the payment and pricing rules that add work, and the costs after launch. It quotes no vendor survey, because we did not open one as a primary source, and none of our prices, because the scope decides them. It sits under our main guide to tourism marketing strategy.

  • Costs

    Web app development cost: what drives the price

    A web app can be a two-screen internal tool or a multi-tenant SaaS product, so "how much?" has no single answer. What you can know is what similar projects have cost, what drives the price up or down, and what you will pay after launch. This guide gives public, dated figures from Clutch and the Bureau of Labor Statistics, the main cost drivers, and how to get quotes you can compare. It is part of our guide to web apps and mobile apps. We publish no rate card of our own.
