Web app development cost: what to budget in 2026
The short answer: in Denmark a simple internal web app typically costs DKK 30,000–250,000, and a medium-sized web app with roles and integrations DKK 250,000–600,000. What moves the price most is not the number of screens but how many systems the web app has to talk to.

A web app is what happens when a website has to do something: an internal tool that replaces the spreadsheet, a portal where your customers find their own orders, or a SaaS product you sell to others. The three look alike in the browser, but they cost very different amounts, and the number of screens rarely explains the difference. The prices below are typical market ranges in Denmark, updated for 2026.
What does a web app cost? Internal tool, customer portal and SaaS
Typical market ranges in Denmark. The same type of web app can sit at either end, depending on roles and integrations.
| Type of web app | Typical price | Typical content | What pushes the price up |
|---|---|---|---|
| Internal tool | DKK 30,000–250,000 | Staff login, lists, forms, reports | Many departments, each with its own rules |
| Customer portal | DKK 80,000–600,000 | Customer login, own data, documents, messages | MitID, data from ERP and accounting, several customer types |
| SaaS product | From DKK 250,000–600,000 and up | Many customers in one system, subscriptions, roles | Separation of customer data, billing, an API for others |
An internal tool has the simplest audience: your own staff, who can be given instructions. A customer portal must work for people you have never met, and it has to show data that often lives in other systems. A SaaS product also has to keep many customers’ data separate and charge for access. To go deeper into portals, see customer portal development.
Why are integrations the biggest cost driver?
A screen with a list and a button is quick to build. Getting that list to show the right orders from your ERP, update stock and send an invoice to e-conomic when the button is pressed is something else. On the market, integrating two to three systems typically costs DKK 80,000–200,000 on its own. It is not the lines of code that cost. It is everything that can go wrong between the systems.
- Documentation. Some systems have a good API, others have almost none.
- Data mapping. A customer number in one system is rarely the same field in another.
- Error handling. What happens when e-conomic is down or a payment is declined?
- Security. Keys and credentials must be stored safely and be rotatable.
- Maintenance. When the other system changes its API, the integration has to follow.
This is where reuse makes the big difference. We have more than 40 pre-built integrations, including e-conomic, Dinero, Billy, MobilePay, Stripe, PostNord, Penneo, MitID, HubSpot and Microsoft 365. When the integration is already built and tested, you pay to adapt it, not to invent it. See the full list under integrations.
What does a web app cost in total over five years?
The one-time price is only half the sum. A web app has to be hosted, updated, secured and backed up for as long as you use it. A common rule of thumb is to budget 15–20 % of the build cost per year for maintenance. Here are three examples worked through over five years.
Total price over 60 months. The market example uses 15 % a year for maintenance. The Ceptiv figures are current package prices.
| Example | Build | Running over 5 years | Total |
|---|---|---|---|
| Medium web app on the market | DKK 300,000 | DKK 225,000 | DKK 525,000 |
| Ceptiv Small | DKK 18,000 | DKK 36,000 (DKK 600/month) | DKK 54,000 |
| Ceptiv Medium | DKK 36,000 | DKK 54,000 (DKK 900/month) | DKK 90,000 |
| Ceptiv Large | DKK 54,000 | DKK 72,000 (DKK 1,200/month) | DKK 126,000 |
The comparison is not entirely fair, and it is not meant to be: a large web app with many roles and eight integrations does not fit in a package. But many SMEs need exactly one tool with one clear purpose, and there the difference is half a million versus under DKK 100,000 over five years. We have put the wider picture in what custom software costs.

What does it look like in practice?
For MyMannaz we brought coordinators, facilitators and participants together in one web app instead of several separate tools. Each group sees what it needs and nothing else. It is a good example of roles often weighing more in the price than screens: the same data, but three different ways in. To see how we build web apps, read about web app development.
