Website maintenance cost: what software upkeep should cost

The short answer: a basic website maintenance agreement typically costs DKK 200–600 a month and a professional agreement DKK 1,500–3,000 a month. For apps and larger systems the rule of thumb is 15–20 % of the build cost per year.

Maintenance is the part of an IT budget most often forgotten, and the part that most often ends up costing the most. Once a website or system is live, it slowly starts to age: libraries develop security holes, operating systems are updated and the integrations you depend on change. This guide shows what maintenance typically costs in Denmark in 2026, and what you should demand for the money.

What does a maintenance agreement cost?

Typical price levels on the Danish market in 2026.

LevelTypical priceWhat is typically included
Basic agreementDKK 200–600 per monthUpdates and backups, rarely support
Professional agreementDKK 1,500–3,000 per monthMonitoring, support, small changes, reporting
Apps and larger systems15–20 % of the build cost per yearNew OS versions, security, bug fixes, integrations
Hosting (often separate)DKK 500–3,000 per yearServer, database, traffic
.dk domain (often separate)DKK 50–150 per yearRegistration and renewal

The wide range exists because the word maintenance covers everything from an automatic plugin-update script to a developer who knows your system and answers the same day. Two agreements at the same price can cover completely different things. Always read what is listed as excluded.

What should a maintenance agreement include?

  • Security updates to the framework and libraries, not just the website itself
  • An SSL certificate that renews automatically
  • Regular backups that have been tested, so they can actually be restored
  • Hosting with monitoring, so someone notices when the site is down
  • Bug fixes at no extra charge when the fault is the supplier’s
  • Support through a clear channel, with a clear answer on when you will hear back
  • Updates for new versions of iOS and Android, if you have an app
  • A clear line between maintenance and new development, and a price for the latter
  • Exit terms: notice period, and that you get the code, data and access with you

How does the 15–20 % rule work for apps and systems?

For apps and larger systems many people use a simple rule: budget 15–20 % of the build cost per year for running and maintenance. An app that cost DKK 200,000 therefore costs DKK 30,000–40,000 a year, or roughly DKK 2,500–3,300 a month. Apps cost more to maintain than websites, because Apple and Google update their operating systems every year, and because an app rarely stands alone: there is almost always a backend and an admin panel behind it. We have covered build prices in how much does an app cost.

Ad hoc on hours

  • Cheap in the months when nothing happens
  • Expensive and unpredictable when something breaks
  • Nobody is responsible for updating proactively
  • Response time depends on the supplier’s calendar

Fixed monthly plan

  • The same amount every month, easy to budget
  • Updates and security happen continuously
  • Hosting, SSL and backups are part of the deal
  • The supplier has an interest in nothing breaking
Two ways to pay for maintenance.

What does Ceptiv’s monthly plan cover?

Everything we build runs on a fixed monthly plan covering hosting, maintenance and updates, support, security and SSL, and backups. There is no separate hosting bill and no hours for keeping the solution healthy. New features are priced separately at a fixed price per extra feature, so the line between running and development is clear.

Monthly prices by package. The plan covers the same things whatever the size.

SmallDKK 600/month (EUR 85)DKK 1,200/month (EUR 165)

LargeDKK 1,200/month (EUR 165)DKK 2,400/month (EUR 325)

Ongoing maintenance is not just insurance. It is what makes it possible to keep building. The platform behind Kirppu grew from one store to more than 30, and that takes a system that is looked after all the way. If you want development and running combined in one ongoing agreement, see development subscription.

What happens when you cancel?

1

Notice

You give 30 days’ notice. The solution keeps running during that period.

2

One-off fee if early

Within the first 15 months: DKK 9,000, 12,000 or 15,000 by package. After that, nothing.

3

Handover

You receive the code and the data. They are yours and always have been.

4

New hosting

You move the solution to another provider or your own server.

Leaving should be as simple as starting.

Questions about maintenance costs

What does website maintenance cost per month?
On the Danish market a basic agreement typically costs DKK 200–600 a month and covers updates and backups. A professional agreement with monitoring, support and small changes runs at DKK 1,500–3,000 a month. Hosting and the domain are often not included and typically cost DKK 500–3,000 and DKK 50–150 a year. Always check what the agreement actually says.
Why does software need maintenance at all?
Because the world around it keeps changing, even when your code stands still. Browsers, iOS and Android are updated, libraries get security fixes, and the systems you integrate with change their APIs. Without maintenance, a solution works fine for a while and then suddenly stops, usually at the worst possible moment. Maintenance is cheaper than an emergency repair.
What is the 15–20 % rule?
It is a common rule of thumb for apps and larger systems: budget 15–20 % of the build cost per year for running and maintenance. If the app cost DKK 200,000, plan for DKK 30,000–40,000 a year. The rule is a rough estimate, but it is useful for making sure the budget does not run dry the year after launch.
Are new features included in your monthly price?
No. The monthly price covers hosting, maintenance and updates, support, security and SSL, and backups. New features after launch are charged at a fixed price per extra feature, so you know the price before you decide. That keeps the monthly price low and predictable, and you only pay for development when you actually want something new.
What happens if we cancel the agreement?
The agreement can be cancelled with 30 days’ notice. You own the code and the data, so you can move the solution to another provider or your own server. If you cancel within the first 15 months, a one-off fee of DKK 9,000, 12,000 or 15,000 applies depending on the package. After 15 months there is no fee, only the 30 days’ notice.
Can you take over maintenance of a solution someone else built?
It depends on how the solution is built. We work in React, Next.js, React Native and TypeScript and do not build on WordPress or page builders. If your solution uses a different technology, we will often recommend modernising it rather than patching it.
