Web apps & platforms

Custom web apps for the work spreadsheets can't handle

When a business outgrows spreadsheets, email threads and off-the-shelf tools that almost fit, a custom web app can tie the process together. We build dashboards, booking systems, client portals and internal tools that run in the browser, with nothing for your users to install.

As a web development company in Sri Lanka working with clients at home and abroad, we focus on software that is fast to use, secure by default and connected to the systems you already rely on, from payment providers to accounting and CRM tools.

What’s included

Everything below is part of a typical web apps & platforms project. We tailor the mix to you.

  • 01

    Dashboards and reporting

    Live views of the numbers you check every day, pulled from your own data and other services, with filters and exports.

  • 02

    Booking and scheduling

    Availability, reservations, reminders and payments for appointments, rooms, classes or equipment.

  • 03

    Member areas and client portals

    Secure logins where customers or members can see their account, documents, orders or course content.

  • 04

    Roles and permissions

    Different access for admins, staff, partners and customers, so people only see and change what they should.

  • 05

    Integrations and APIs

    Connections to payment gateways, accounting, CRM, email and messaging tools, plus an API if other systems need to talk to yours.

  • 06

    Security and reliability

    Encrypted connections, sensible authentication, regular backups and error monitoring, so problems are caught early.

How we approach it

  1. Step 01

    Map the workflow

    We sit with the people who will use the app and document how the work happens today, including the exceptions.

  2. Step 02

    Prototype the key screens

    Clickable prototypes of the main tasks let your team try the flow and correct it before any code is written.

  3. Step 03

    Build in stages

    We release a first working version focused on the core task, then add features in short cycles based on real use.

  4. Step 04

    Run and improve

    After launch we monitor performance and errors, handle updates and security patches, and plan the next round of changes with you.

Web apps & platforms

Common questions

A website mainly presents information. A web app lets people do things: log in, book, manage data, run reports or complete a workflow. Many projects combine both, with a public site and a logged-in area behind it.

If an existing product covers most of what you need, it is usually cheaper to adopt it. A custom app makes sense when your process is a competitive advantage, when you are paying for several tools that don't connect, or when nothing on the market fits.

Usually, yes. Most modern accounting, CRM, payment and messaging tools offer APIs. We check what each system allows during discovery and plan the integrations around that.

You do. We agree ownership and handover terms in the contract, keep the code in a repository you have access to, and document how it is set up and deployed.

Yes. We offer ongoing support covering hosting, monitoring, security updates, bug fixes and new features. The level of support is agreed with you based on how critical the app is to your business.
