The verdict in three sentences
A launched site is not a finished site: without maintenance it ages, gets hacked and loses visibility. In Amsterdam in 2026, budget 100 to 600 EUR/month for maintenance depending on scope, plus hosting and recurring GDPR and CMS patching. The right call between pay-as-you-go and a retainer depends on your update frequency and your tolerance for downtime risk.
The annual maintenance budget line by line
Here are the 2026 ranges seen in Amsterdam for a standard business website.
| Line item | 2026 cost (EUR) | Frequency |
|---|---|---|
| Maintenance (basic retainer) | 100 - 250 | per month |
| Evolutive maintenance (dev) | 300 - 600 | per month |
| Managed hosting | 30 - 120 | per month |
| Domain renewal | 12 - 30 | per year |
| SSL certificate | Included | - |
| Automated backups | Included in retainer | daily/weekly |
An SME updating its site 2-3 times a year gets by on a low retainer; a company publishing content weekly needs evolutive maintenance.
Retainer vs pay-as-you-go
The choice depends on your volume of work and your need for responsiveness. Here is the 2026 comparison.
| Criterion | Pay-as-you-go | Monthly retainer |
|---|---|---|
| Cost per task | 90 - 180 EUR/h | Included up to quota |
| Response time | 2 to 10 days | 24 to 72 h (SLA) |
| Security updates | On request | Automatic |
| Backups | Optional | Included |
| Best for | Stable, rarely edited site | Active site, regular content |
As a 2026 rule: beyond 6-8 tasks/year, a retainer becomes cheaper and, above all, safer (security flaws are patched without delay).

Mini case study
Sanne, COO of a professional-services firm in Amsterdam, must budget year 1 after launching a 12,000 EUR site. She publishes one update per month and wants zero hacking risk plus GDPR compliance.
Calculation: maintenance retainer 200 EUR/month (2,400 EUR/year) + managed hosting 80 EUR/month (960 EUR/year) + domain 20 EUR/year = 3,380 EUR/year, around 280 EUR/month all in. Pay-as-you-go, her 12 updates at 150 EUR would cost 1,800 EUR, but with no guaranteed security patching or backups: a single breach would cost more than the gap. She picks the retainer.
FAQ
Why pay for maintenance if the site works? Because an unmaintained site accumulates security flaws and gets hacked: recovery often costs 2,000 to 5,000 EUR, far more than 12 months of retainer. Maintenance is insurance.
What does a maintenance retainer include in Amsterdam? In 2026 a 100-600 EUR/month retainer covers security updates, backups, a quota of change hours and a guaranteed response time (SLA 24-72 h), plus GDPR-driven patching.
What does hosting a business site cost? Between 30 and 120 EUR/month in 2026 depending on traffic and needs (managed, backups, CDN). SSL is now included.
Can I host and maintain it myself? Technically yes, but the time and error risk quickly outweigh the saving. For a company, a managed retainer is safer and frees your team.
Is domain renewal included? Rarely in the maintenance retainer: budget 12 to 30 EUR/year extra. Never forget it, or you lose the domain.
