Web app development that fits the way you work

The short answer: in the Danish market a simple internal tool typically costs DKK 30,000–250,000, and a medium web app with roles and integrations DKK 250,000–600,000. We build web apps in fixed packages from DKK 18,000 plus DKK 600 a month, and you own the code.

A web app is software that runs in the browser: no installation, no app store, just an address and a login. It can be an internal tool only your staff ever see, or a platform your customers pay for. What they share is that they do something – a web app is not a website with text and pictures. If you are unsure whether you need a web app or a phone app, start with web app vs native app.

What kinds of web apps can you have built?

The four kinds of web app we are asked for most often.

TypeWhat it doesExample
Internal toolBrings tasks, planning and data into one place instead of spreadsheets and emailScheduling, stock, case handling
PortalGives customers, partners or staff self-service behind a loginGrundfos iGRID, Mannaz IT support
SaaSA product many customers subscribe toSubscription platform on Stripe
BookingSlots, spaces or resources that customers reserve and pay forKirppu stand booking

For MyMannaz we brought coordinators, facilitators and participants into one web app instead of separate solutions for each group. For Kirppu we built the booking system behind Denmark’s largest chain of flea market supermarkets, which grew from one store to more than 30 on the same platform. Both are web apps, but they solve very different problems – which is why they look nothing alike under the bonnet.

Which technology is the web app built on?

We build in React and Next.js with TypeScript. It is a widely used, modern stack that a great many developers know, so you are not locked in to us. We don’t build on WordPress or page builders. Everything is written from scratch, so the data model fits your business rather than the other way round.

  • React and Next.js: fast screens and good SEO on the public parts
  • TypeScript throughout, so bugs are caught before users see them
  • The same logic can be reused in a React Native app if the need arises
  • Hosting, SSL, backups and updates are part of the monthly plan

Which systems can the web app connect to?

A web app only becomes truly useful when it talks to the systems you already use. We have more than 40 pre-built integrations, covering Danish accounting systems, payments, shipping, payroll and digital signature among others. Each package has a fixed number of integrations: one in Small, two in Medium and three in Large. So you know up front what is included.

How does web application development work?

1

Brief

You tell us what needs solving. Within 24 hours you get a written fixed-price proposal.

2

Design

We design the screens and test the flow before building, so changes are cheap.

3

Build

We build in short rounds and show progress on a staging site you can click around yourself.

4

Integrations

Data is connected to accounting, payments or login, so nothing is typed in twice.

5

Launch and running

The web app goes live, and the monthly plan covers hosting, support and updates.

From brief to live – with the price locked from the start.

How much does web app development cost?

Typical market ranges in Denmark: a simple internal tool costs DKK 30,000–250,000, integrating 2–3 systems DKK 80,000–200,000, and a medium web app with roles and integrations DKK 250,000–600,000. Our packages are fixed, however many hours it takes us:

LargeDKK 54,000 (EUR 7,500)DKK 1,200 (EUR 165)363

A feature is, for example, a login, a filtered list, a form or a report. Extra features after launch come at a fixed price per extra feature. The full calculation, including what drives the price up, is in the guide web app development cost, and the packages are on pricing.

What drives the price of a web app up?

Two web apps with the same number of screens can have very different prices. It is rarely the screens themselves that cost – it is what happens behind them. When we write your proposal, we look at five things in particular:

  • Number of features: every list, form, report or automation counts
  • Roles: the more user types with their own permissions, the more logic
  • Integrations: every system it has to talk to is a small project of its own
  • Data and rules: calculations, approval flows and history
  • Design level: a simple internal tool needs less than a product customers pay for

That is why we price in features and integrations rather than hours. It forces both of us to be specific about what is being built, and it makes the price predictable for you.

FAQ

Questions about web app development

What is the difference between a website and a web app?
A website presents information: text, images and a contact form. A web app lets users get things done – log in, create, edit, book, pay or see their own data. The line is blurry, but the rule of thumb is simple: if users have a login and their own data, it is a web app, and it needs to be built and run as software.
How much does a web app cost?
In the Danish market a simple internal tool typically costs DKK 30,000–250,000, while a medium web app with roles and integrations is DKK 250,000–600,000. With us the price is fixed: DKK 18,000 plus DKK 600 a month for 12 features and one integration, DKK 36,000 plus DKK 900 a month for 24 and two, or DKK 54,000 plus DKK 1,200 a month for 36 and three.
How long does it take to build a web app?
It depends on scope. A focused first version with one core flow typically takes 6–12 weeks, while larger solutions are built in stages. The timeline is in the written proposal you receive within 24 hours of your brief, so you can plan the launch from day one.
Does the web app work on mobile too?
Yes. We design web apps to work on desktop, tablet and phone. If the solution needs the camera, push notifications or offline use, it may be worth building a React Native app alongside it. That app can reuse much of the web app’s logic, so you don’t pay for everything twice.
What does the monthly fee cover?
It covers hosting, maintenance and updates, support, security and SSL, and backups. Those are the running costs that otherwise arrive as surprises after launch. The amount is DKK 600, 900 or 1,200 a month depending on the package, and you can cancel with 30 days’ notice.
Can we take the web app to another supplier?
Yes. You own the code and data, and the stack – React, Next.js and TypeScript – is widespread enough that other developers can take it over. If you cancel within the first 15 months, there is a one-time fee of DKK 9,000, 12,000 or 15,000 depending on the package. After that, leaving costs nothing.
