Managed Hosting for a B2B Website: Cost in 2026

The verdict in three sentences

Managed hosting for a B2B website costs between 150 and 500 EUR/month in 2026 depending on criticality, including 24/7 monitoring, backups, security updates and a 99.9% SLA. The alternative "hosting only + on-demand maintenance" is cheaper on paper but transfers downtime risk onto you. As soon as one hour of downtime costs more than a few hundred euros of revenue, managed pays for itself.

What managed operations cover

Managed hosting is not hosting: it is full operation. Here are the 2026 tiers and their scope.

The SLA and the recovery time guarantee are the real differentiators: paying for a recovery of under 2 hours means buying the certainty of a fast restore after an incident.

Managed vs hosting only: the real math

Comparing the two options requires including the cost of downtime, often ignored. Here is an annual order of magnitude for a lead-generating B2B site.

*Estimated lost revenue based on the revenue the site generates. Managed smooths the spend and removes incident-driven variability.

Quantifying the cost of downtime

An outage costs more than immediate revenue: it damages reputation and SEO (Google penalises frequently unavailable sites). For a site generating 30,000 EUR of attributable monthly revenue, one hour of daytime downtime can represent 150 to 400 EUR of direct lost revenue, not counting lost leads and degraded image with prospects.

Mini case study

Claire, CFO of a manufacturing SME in Lyon, runs a brochure + catalogue site generating 25 leads/month valued at 300 EUR. She is currently on hosting only at 45 EUR/month and pays for one-off interventions (about 1,800 EUR/year), with two undetected outages last year totalling 9 hours of downtime.

She switches to managed business at 320 EUR/month (3,840 EUR/year). In return, she removes the 1,800 EUR of interventions and above all the 9 hours of downtime that had cost her about 6 lost leads (1,800 EUR) and an SEO incident. The real net premium is only ~700 EUR/year, for total peace of mind, a 99.9% SLA and a single point of contact. For a CFO, the call is simple: predictability is worth that delta.

FAQ

What is the difference between hosting and managed operations?

Hosting provides the server; managed operations run everything (monitoring, backups, security, support). You delegate operational responsibility, not just the machine.

What does a 99.9% SLA actually mean?

It allows about 8.8 hours of downtime per year at most. A 99.95% SLA drops to under 4.4 hours, hence its higher price.

Are backups really included?

In a serious managed offer, yes: automatic daily backups with tested restore. Require the frequency and retention period in writing.

Can I keep my current host and add managed operations?

Often yes, if the environment is compatible. Otherwise a migration to the vendor's infrastructure is proposed and priced separately.

Is managed worth it for a small brochure site?

If the site generates no direct revenue, hosting only may suffice. As soon as it carries leads or orders, managed becomes a profitable defensive investment.
