The verdict in three sentences
A site delivered without maintenance is a time bomb: security holes and update incompatibilities appear from the first year. In Amsterdam in 2026, a maintenance plan is sized from 80 to 900 EUR/month depending on included hours and SLA. The right call is not price but the model: fixed fee for predictability, time-and-materials for flexibility.
The three maintenance tiers in 2026
A manager must pick a tier that matches the criticality of the site. Here is the 2026 Amsterdam grid.
| Tier | Price/month | Included | For whom |
|---|---|---|---|
| Basic | 80-200 EUR | Updates, backups, security, monitoring | Brochure site |
| Evolving | 200-600 EUR | Basic + 2-8 h changes/month | Active site, blog |
| Managed | 300-900 EUR | Evolving + SLA, on-call, hosting | Critical site, e-commerce |
| Custom | 900 EUR+ | 99.9 % SLA, 24/7, multi-site | Group, corporate |
A basic plan covers technical survival; evolving includes a continuous-improvement budget; managed adds an availability guarantee.
Fixed fee versus time-and-materials
The core decision is the billing model. Here are the concrete 2026 differences.
| Criterion | Fixed monthly fee | Time-and-materials |
|---|---|---|
| Indicative price | 80-900 EUR/month | 60-110 EUR/hour |
| Budget predictability | High | Low |
| Change flexibility | Limited to hours | Full |
| Response time | Contractual SLA | Based on availability |
| Hour rollover | Often no | N/A |
| Ideal if | Regular needs | Occasional needs |
For a living site (content, campaigns, small changes), the evolving fixed fee is almost always more profitable; for a frozen site, time-and-materials avoids paying for unused hours.
The ROI of a well-sized plan
Maintenance cuts the risk of downtime or an exploited breach by around 70 % and divides the average time to recovery by three. An e-commerce site down for a day can lose several thousand euros of revenue; on that basis, managed hosting at 500 EUR/month pays for itself on the first incident avoided.

Julien, manager of a 22-employee trading SME in Amsterdam, runs a catalogue site with a quote form. He hesitates between no maintenance and an evolving plan at 350 EUR/month, or 4,200 EUR/year. In year 1 without maintenance he suffers a hack (SEO injection): cleanup 1,800 EUR, plus two weeks of deindexing estimated at 6,000 EUR of lost leads, totalling 7,800 EUR. With the plan the incident is avoided and he gets 4 hours of changes a month. Cost 4,200 EUR, risk avoided 7,800 EUR: a net ROI of 3,600 EUR in the first year, before improvement gains.
FAQ
How much does a brochure-site maintenance plan cost in Amsterdam in 2026?
A basic plan runs 80 to 200 EUR/month: updates, backups, security patches and monitoring. It is the minimum to avoid exposing the site to a breach in the first year.
What is the difference between maintenance and managed hosting?
Maintenance fixes and updates the site; managed hosting adds hosting management, an availability SLA and on-call cover. Managed hosting starts around 300 EUR/month and targets critical sites.
Is a fixed fee always cheaper than time-and-materials?
No. For a frozen site with no changes, time-and-materials at 60-110 EUR/hour avoids paying for unused hours. For an active site, the evolving fixed fee is more profitable and more predictable.
What does a 99.9 % SLA mean in practice?
It allows about 8 h 45 of downtime per year. Below that, the provider commits to penalties. It is relevant for e-commerce and unnecessary for a simple brochure site.
Are unused change hours carried over?
It depends on the contract: many fixed fees do not roll over. Negotiate a one-or-two-month rollover, or conversion into tickets, so you do not lose paid hours.
