Concept interface, not client work

What is web app development?

A web app is software that runs in a browser and behaves like an application rather than a page: users sign in, work with their own data, and the software remembers what they did. Dashboards, client portals, booking systems and internal tools are all web apps.

The difference from a website is what the software does rather than how it looks. A website presents the same information to everybody and is mainly read. A web app has accounts, permissions, records that change, and logic that enforces rules. That distinction drives everything else: a web app needs a database, an authentication system, and a plan for what happens when two people edit the same thing.

Who web app development is for

  • Companies running on spreadsheetsWhen a shared spreadsheet has quietly become the system the business depends on, and it keeps breaking.
  • Service businesses with clients to serveA portal where customers can see their own orders, documents, bookings or invoices without emailing to ask.
  • Operations and admin teamsInternal tools that replace manual steps, with roles so people only see what they should.
  • Software businessesA SaaS product with subscriptions, tenants and a dashboard as the main interface.

How web app development works at ABM

  1. 01Map the workWe map what people do today, step by step, including the parts that happen in email and spreadsheets.
  2. 02Data modelThe records, their relationships and who is allowed to see each one. Getting this right early prevents expensive rework.
  3. 03Interface designScreens designed around the tasks, not around the database. Prototyped before development starts.
  4. 04BuildFront end, back end and integrations, on a staging environment you can open at any point.
  5. 05Migration and launchExisting data is imported and checked, people are shown the new system, and the old one is retired deliberately.
  6. 06IterateThe first weeks of real use always produce changes. We plan for them rather than treating them as failures.

Technologies and integrations

The exact stack is chosen per project and agreed with you in writing before development starts. These are the tools and categories we work with for web app development.

Front end

  • React
  • Next.js
  • TypeScript

Back end

  • Node.js
  • REST and GraphQL APIs

Data

  • Relational databases
  • Migrations
  • Reporting queries

Platform

  • Authentication and roles
  • Hosting and deployment
  • Monitoring

When to choose web app development

  • People need accounts, and different people should see different things.
  • The data changes constantly and more than one person edits it.
  • The work currently happens in spreadsheets, email threads or several disconnected tools.
  • You need it to work on a laptop, a tablet and a phone without shipping an app to a store.

When something else fits better

  • Website DevelopmentVisitors only need to read and get in touch. A site with a CMS is faster to build and cheaper to run.
  • Mobile App DevelopmentThe product is used on the move, offline, or needs the camera, location or push notifications.
  • Enterprise Software DevelopmentThere are several systems, several departments and integration or compliance requirements to satisfy.

Questions

Web App Development: common questions

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

A website is mainly read: it presents the same content to every visitor. A web app is used: people sign in, work with their own records, and the software enforces rules about what each person can do. If your project needs logins, permissions and data that changes, it is a web app, and it needs a database and an authentication system behind it.

Can a web app replace our spreadsheets?

Usually, yes, and that is one of the most common reasons businesses commission one. The value is not only the interface: it is having one version of the data, a record of who changed what, and rules the software enforces instead of relying on everyone remembering them.

Will it work on phones?

Yes. Web apps are built responsively so they work in a mobile browser. If your users need offline access, push notifications or device hardware, that is the point at which a mobile app becomes worth the extra work.

Can it connect to the tools we already use?

If those tools have an API, they can usually be connected, so data moves without copy and paste. That work is covered under API development and integration and is best scoped at the same time as the app itself.

What happens to our existing data?

Existing data is exported, cleaned and imported as part of launch, and checked against the source before the old system is retired. Messy historical data is normal and is planned for rather than discovered late.
