Website Maintenance Retainer Pricing in Berlin: 2026 SLA Guide

The verdict in three sentences

A website maintenance retainer in Berlin costs 60 to 120 EUR per month for updates and backups, and 200 to 500 EUR with 2 to 4 hours of changes and a 4 business-hour recovery SLA. The basic tier works for a brochure site with no critical form; as soon as the site drives leads or sales, the SLA retainer is the rational choice. A hack costs an SME 15,000 to 50,000 EUR on average, the equivalent of 3 to 20 years of maintenance.

The three tiers compared

The three quotes a CFO receives look alike on paper. The differences hide in response times, backup frequency and what counts as a "change".

Beyond the retainer, an hour of work bills at 70 to 110 EUR in Berlin, sometimes up to 130 EUR for senior developers.

What an incident costs without the right retainer

Unpatched WordPress sites remain the main target of automated attacks: a vulnerable plugin is exploited within days of the flaw being published. The real cost of a hack goes far beyond the technical fix.

With daily backups and a 4-hour SLA, most incidents are resolved in half a day by restoration, with no data loss.

How to choose the right tier

Three questions are enough to steer the decision:

• What is one day of website worth? If a day of downtime costs over 500 EUR (leads, orders, bookings), go for Standard at minimum.
• Does the site store personal data? Forms, customer accounts or online quotes require daily backups and at least 30 days of retention under GDPR.
• Do you order regular changes? If you buy more than 2 hours of changes per month outside the retainer, a package with included hours is 20 to 30% cheaper.

Also check three clauses: reversibility (admin access and code handed over at contract end), rollover of unused hours and commitment length (12 months is standard, beyond that negotiate a 10% discount).

Mini case study

Katrin, CFO of a 45-employee industrial SME in Berlin, receives three offers for a site that generates 25 quote requests per month, 4 of which turn into orders averaging 9,000 EUR. One day of downtime therefore costs about 1,200 EUR in potential revenue.

Essential at 90 EUR per month, or 1,080 EUR per year; Standard at 250 EUR, or 3,000 EUR; Premium at 420 EUR, or 5,040 EUR. She already orders 3 hours of changes per month outside any contract at 90 EUR per hour, or 3,240 EUR per year. With Premium those hours are included: total cost moves from 1,080 + 3,240 = 4,320 EUR to 5,040 EUR, 720 EUR more per year, plus a 4-hour SLA and 90 days of backups. One avoided 3-day incident repays that gap five times over.

FAQ

Does the retainer include hosting?

Not always. Managed hosting is often billed separately, 15 to 60 EUR per month for an SME. Check who is responsible if the server goes down.

What happens to unused change hours?

Good contracts allow rollover for 1 to 3 months. Without a rollover clause, hours are lost, which raises the real cost by 15 to 25%.

Is a 4 business-hour SLA enough?

For most B2B SMEs, yes. A 24/7 SLA costs 2 to 3 times more and is only justified for a high-volume online store.

Can we switch provider mid-contract?

Yes if a reversibility clause exists, with 1 to 3 months notice. Require handover of admin access, backups and source code.

What does taking over a poorly maintained site cost?

An audit and upgrade cost 800 to 3,000 EUR before the retainer starts. Beyond 2 years without updates, a rebuild may be more cost-effective.
