"Website" and "web application" are often used interchangeably, but they're two different things. The distinction decides whether you need a presentation of your business, or a working tool that runs your processes. This article explains what a web application is, how it differs from a website and when your business benefits from one.

## Website versus web application: the difference

The simplest distinction: **a website shows information, a web application _does_ something.**

- A [website](/en/web-development/) informs visitors: who you are, what you offer, how to reach you. The visitor reads and clicks through.
- A web application lets users perform tasks: log in, enter data, run calculations, process orders, view dashboards. The user _works_ in it.

A webshop sits somewhere in between: it's a website that also does something (ordering and paying). Once the logic gets more complex — accounts, roles, workflows — we call it a web application.

## What is a web application, exactly?

A web application is software that runs entirely in the browser, without installation. Your team and customers simply use it via a link, on any device. Behind the scenes sits the same power as [custom software](/en/custom-software/): user permissions, validation, a database and integrations with other systems.

> A website is your digital business card. A web application is your digital workshop.

## Examples of web applications

- A **customer portal** where clients view their data, quotes or invoices.
- A **planning or booking system** that follows your way of working exactly.
- A **dashboard** with real-time insight into revenue, stock or KPIs.
- An **internal business system** that replaces scattered Excel sheets (see also: [when your business outgrows Excel](/en/blog/outgrowing-excel-custom-software)).

## When does your business need one?

Choose a web application when:

- Your process is more than showing information — real work needs to happen.
- Multiple people need to collaborate on the same data at once, safely.
- You're missing features in existing packages, or paying for lots you don't use.
- You want your systems to [work together](/en/integrations/) instead of in isolation.

## What does it cost and how do you start?

As with custom software, the investment depends on scope: a focused first version is a manageable step, a full business system asks for more. You always get a fixed price upfront — see the indicative prices at [pricing](/en/pricing/). The smartest start is small: one process that costs the most time now, developed into a working application.

## Conclusion

If you mainly need a business card, a website is enough. If real work has to happen — processing data, collaborating, automating — a web application is the right choice. Torn between the two? We're happy to think it through with you.
