The verdict in three sentences
A Next.js site does not have the weaknesses of a plugin-heavy WordPress, but it relies on hundreds of npm packages that must be updated, or it degrades within 12 to 18 months. A serious support plan costs between EUR 90 and 450 per month in 2026, depending on the guaranteed recovery time and the hours of changes included. For a Berlin SME whose website generates quote requests, the mid-tier plan at around EUR 220 is usually the right trade-off.
What Next.js website support actually covers
The CFO reviewing the agency's proposal often sees a single line called "maintenance". It needs to be broken down:
- Dependency updates: Next.js, React and libraries ship fixes every month. A major Next.js version arrives roughly once a year.
- Security patches: a critical alert on a package must be handled within 24 to 72 h depending on the plan.
- Backups: code versioned in Git, plus the database, media and CMS content, with a restore test at least quarterly.
- Monitoring: uptime checked every 1 to 5 minutes, SMS or email alerts, Core Web Vitals tracking.
- Changes: a new page, a new form, a price update. This is the line that causes the most friction when it is not priced.
2026 service level grid
| Item | Essential | Standard | Premium |
|---|---|---|---|
| Monthly price (excl. VAT) | EUR 90 to 150 | EUR 180 to 280 | EUR 320 to 450 |
| Dependency updates | Quarterly | Monthly | Monthly + weekly watch |
| Critical security patch | Within 72 h | Within 48 h | Within 24 h |
| Guaranteed recovery time | 24 business hours | 8 business hours | 4 h, 7 days a week |
| Backups | Daily, 7 days | Daily, 30 days | Daily, 90 days + off-site |
| Changes included | 2 h / month | 4 h / month | 6 h / month |
| Reporting | Twice a year | Monthly | Monthly + quarterly review |
| Extra hour | EUR 75 | EUR 70 | EUR 65 |
These figures are a 2026 order of magnitude for agencies and freelancers serving German SMEs. A 12-month commitment with three months' notice is the norm.
What skipping support really costs
| Scenario | Probability over 24 months (estimate) | Average cost to the SME |
|---|---|---|
| Contact form broken and unnoticed for 3 weeks | High | 8 to 15 lost leads |
| Major Next.js upgrade done in a rush | Very high | EUR 2,500 to 6,000 |
| Dependency vulnerability exploited | Low to medium | EUR 3,000 to 12,000 + reputation |
| Site down for 2 days with no alert | Medium | Lost traffic and SEO rankings |
| Host changes its terms | Medium | EUR 1,500 to 4,000 migration |
| CMS data lost with no tested backup | Low | Rebuild: EUR 3,000 to 8,000 |
The most common scenario is not a hack, it is technical debt: a site left 2 years without updates often costs more to bring back up to date than 24 months of an Essential plan.
Mini case study
Katrin, CFO of a 40-person industrial packaging SME in Berlin-Spandau, receives three proposals for the Next.js site delivered last year. The site generates 25 quote requests a month, with a 20% conversion rate and an average order of EUR 6,000.

Standard plan at EUR 220 a month: EUR 2,640 a year. A single broken form left unnoticed for 3 weeks loses about 18 requests, so 3.6 orders and EUR 21,600 of revenue. The 4 hours of included changes also replace roughly 48 hours of ad hoc work per year, worth EUR 3,360 at EUR 70. The plan is paid for by the included changes alone, and monitoring covers the commercial risk.
FAQ
Does a Next.js site really need support?
Yes. A typical Next.js project ships 300 to 800 dependencies, several of which get security alerts every quarter. Without updates, catching up after 2 years often costs EUR 2,500 to 6,000.
What does a 4-hour recovery time mean?
It is the maximum time to bring the site back online after an outage is reported or detected. It differs from the response time, often 1 h, and should come with a penalty, for example 10% of the monthly fee per hour of overrun.
Are unused hours carried over?
It depends on the contract. The most common practice is a carry-over of 1 to 3 months at most. Get it in writing before signing.
Is hosting included?
Rarely in the Essential plan. Budget EUR 20 to 80 extra per month for Vercel, Hetzner or another host suited to an SME.
Can we switch provider mid-contract?
Yes, if the code sits in a Git repository you own and a reversibility clause requires handover of all access within 10 business days.
