In Short

What Is a Custom Web Application?

A custom web application is software that runs in a web browser and is built for one business’s own tasks, such as quoting, booking, ordering or managing jobs. Unlike a website, which mainly shares information, a web app lets people log in, enter and update information and get work done, on any device, with nothing to install.

Where You Are Today

Replacing Spreadsheets or Rebuilding an Old App: Two Ways to Start

Replace spreadsheets and manual work

Spreadsheets are brilliant for getting started, but they were never built to be a business system. Once several people edit the same file, versions drift apart, formulas get overwritten and nobody can see who changed what. We turn the spreadsheet into a web app with a real database, user roles and a full history, and move your existing data across.

Rebuild or modernize an existing app

Many businesses run on an app that was built years ago and is now hard to change, slow or unsupported. We review what you have, keep what still works and plan a rebuild or a step-by-step modernization, so your team is never left without a working system.

Data and permissions

Sensitive data, approvals and audit trails need more careful building

What is the difference between a web app and a website?

A website mainly presents information and wins inquiries, while a web application lets people log in and do something, such as book, order, track or approve. Many businesses need both, and they work best when they are planned together.

It depends on the number of users and screens, the integrations and how sensitive the data is. We give you one fixed quote from a written scope after a free discovery call, so you know the cost before any work starts.

It depends on the scope. We agree the milestones and the launch plan with you in writing before we start, and you see working previews throughout, so there are no surprises at the end.

Yes. We turn the spreadsheet into an app with a real database, user roles and a full change history, and move your existing data across, so nothing is lost and everyone works from the same information.

Yes. We review what you have first. Sometimes a few fixes are all it needs; sometimes a step-by-step rebuild is safer than a big switch. Either way, your team keeps a working system throughout.

Start with a web app if people use computers or need access from any device without installing anything. Choose a mobile app when you need offline use, push notifications, the camera or GPS, or a listing in the app stores. Many businesses start with a web app and add a mobile app later.

A progressive web app is a web app that can be added to a phone’s home screen, loads quickly and keeps working on a weak connection. It is a good middle ground when you want an app-like experience without publishing to the app stores.

We plan security in from the start: secure logins, role-based permissions, encrypted connections, input validation and regular updates, then test every role and permission before launch.

Yes, in most cases. If a tool has an API, such as your CRM, QuickBooks, Xero, Stripe or Google Workspace, we can connect it so data moves without copy and paste.

Ownership of the code, the data and the accounts the app runs on is set out in writing before work starts.

We use widely supported, well-documented technology, so any qualified developer can maintain your app in the future. For React web app development we pair React or Next.js and TypeScript with Laravel or Node.js on the server.
