Services and prices
The prices below are guide prices. The actual quote is tailored to your case after a short, free initial conversation.
Construction & property
Housing cooperatives, property management firms, property developers, surveying offices, landscaping businesses: companies with 10 to 50 employees in Berlin and Potsdam. You have a lot of administration, often with tenant and property data and the duties that come with the GDPR. Your systems need to grow with you.
-
1.1Your own cloud
Nextcloud, Office, backup, monitoring, mail and a password manager on a server just for you, set up and looked after.
After the setup, the cloud is yours. I pass the server on at cost (usually 4 to 15 €/month), or you rent it in your own name.
Setup 5.000 to 8.500 €
maintenance 200 to 500 €/month
Guide price -
1.2Does your safety net hold?
Inventory, a real restore test, monitoring set up, and three prioritised recommendations.
A backup that has never been restored does not count when it matters. The test shows beforehand whether it holds.
from 1.300 € for 2 days
maintenance on request 30 to 80 €/month
Guide price
How you can tell you need thisWhen everyone in your office says ‘Dropbox’ and each of them means something different. Or when tenant and property data is scattered across devices and inboxes.
Regulated businesses
Medical practices, funeral directors, small law firms, care services: businesses with 3 to 20 employees that handle data under professional confidentiality and special categories of data under Art. 9 GDPR. Often nobody can say for certain whether the systems are clean.
-
2.1On-site security check-up
A walk-through of 60 to 90 minutes and a written action report with traffic-light rating (PDF).
A reportable incident involving patient or client data quickly runs into four or five figures. The check-up finds the gaps beforehand, at a fixed price.
290 to 390 €
Fixed price -
2.2NIS2/maturity pre-assessment
One assessment day. Result: inventory, overview of data flows, gap list, roadmap and report (15 to 25 pages).
If NIS2 applies to you, you can be audited. The pre-assessment shows beforehand where you need to improve.
1.900 to 4.500 €
follow-up check on request 800 to 2.500 €
Guide price -
2.3Mandatory training in your Nextcloud
Training on data protection, the AI Act or occupational safety, directly in your Nextcloud with the open-source app learning-nc. This includes set-up, groups, templates for the works agreement (Betriebsvereinbarung) and data protection, and a briefing for your admins. The training app is freely available in the Nextcloud App Store.
Anyone who completes the training receives a signed certificate that outsiders can verify themselves. No second system, no third-party cloud.
quote after initial conversation
How you can tell you need thisWhen the practice PC with the patient system open can be seen from the waiting room. Or when you hear ‘NIS2’ and do not know whether it applies to you.
The pre-assessment is neither an attestation nor a certification.
Organisations
Clubs and associations (Vereine), NGOs, neighbourhood and community work, elected representatives, small editorial teams: you depend on Google and WhatsApp even though your communication is sensitive. Independence matters to you, but the budget is small.
-
3.1Start safely
Inventory, risk analysis and recommendations.
The low-threshold entry point: know where you stand before you put money into technology.
200 to 600 €
Guide price -
3.2Website and channels check from the outside
I check what anyone can see from the outside: your website (encryption, outdated software, legal notice (Impressum), privacy policy, accessibility, findability) and your channels in social media and the press. Result: a report with traffic-light rating and priorities. On request, also which AI tools save your public relations work time on a small budget.
The check needs no access to your systems and no on-site appointment. Afterwards you can see in black and white where things are stuck and what comes first.
290 to 390 €
Fixed price -
3.3Sovereign setup
Nextcloud, encrypted communication, roles and backup.
One-off instead of a subscription. Afterwards you need neither Google nor WhatsApp for member data and communication.
500 to 2.500 €
Guide price -
3.4Structure & collaboration
Organise documents, clarify the team structure, introduce simple workflows.
You win back the time currently lost to searching and reconciling three versions of the same Excel file.
300 to 1.500 €
Guide price -
3.5Organisational memory
Collecting and organising an organisation’s archive, photos and memories, and making them accessible to members, on your own infrastructure.
by arrangement
-
3.6Light support
Monthly support within an agreed scope, for organisations without an IT position of their own.
Someone reliably looks after it, without you having to create a job for it.
100 to 250 €/month
Guide price
How you can tell you need thisWhen your member list lives in a WhatsApp group and three versions of an Excel file.
Cross-party, democratic, oriented towards the common good. No party-political positioning.
Your own AI setup
For individuals and creatives with a small team who want to use AI without storing their assistant’s memory with a large provider. Expressly also for sceptics.
Your assistant’s memory sits on your own hard drive, and the language model behind it can be swapped. Models change, the foundation stays.
-
4.1Where you stand
What are you already using, where is your data, how dependent are you? Result: a readable report and an honest recommendation.
150 to 250 €
Fixed price -
4.2Roadmap
Your path to your own setup: which building blocks, which level (entry, hybrid or fully local), which running costs.
250 to 400 €
Guide price -
4.3Build
We build your setup together and document it, so you can carry it on yourselves.
If a simple subscription is the right answer for you, I will tell you so beforehand.
based on effort, usually 1 to 2 days at 650 € each
Guide price
How you can tell you need thisWhen you use AI every day and do not know where all of it is stored.
The memory runs locally without trouble. If the language model is to run on your machine as well, it needs a powerful graphics card. Otherwise you use a cloud provider, for example one from the EU. Then not everything is private, but you know exactly what goes where.
3D survey & documentation
Planning and engineering offices, building owners, administrations, clubs: anyone who wants a building, a stand of trees or a site captured precisely and documented in a traceable way.
Depending on the project, a surveying office takes on the laser scan and georeferencing as a subcontractor. I evaluate, draw and deliver in the format and coordinate system of your planning.
-
5.1Survey from the point cloud
Sections, views and elevations from laser scan data, as DXF/DWG in the coordinate system of your planning. I deliver the point cloud alongside as E57. You can view, measure and discuss the data with siteBits in the browser, on your own server.
Measured instead of estimated, and verifiable, because the raw data comes with it.
Quote per project
day rate 650 € -
5.2360° documentation
Walk-through 360° panoramas of a building, construction site or grounds. They run in the browser and sit on your server or mine instead of on a platform.
The panorama records a state that cannot be captured later: before the conversion, before the pruning, right after completion.
Quote per project
How you can tell you need thisWhen a plan depends on existing dimensions that nobody knows exactly, or a state has to be documented before it changes.
Not an official survey result and not an expert report. Both stay with the responsible professionals.
Websites & project support
Freelancers, small businesses, creatives and clubs who need a website and want to keep it in their own hands. And businesses without an IT position of their own that have an IT project ahead of them and nobody to make sense of it for them.
I build and run my own sites on the same pattern: souverain-systems.de sets no cookies and loads nothing from third-party servers. You can check that yourselves on the Rabbit Hole page.
-
6.1Your own website
I build a lean site and set up the domain and the hosting. Static, so fast and with little attack surface. On request I then take over the running of it: hosting, monitoring, backups and updates.
Domain, code and accounts are in your name. The service can be cancelled monthly, and you can take over yourselves or move to someone else at any time.
Set-up from 650 €
running from 20 €/month
changes 90 €/hour, billed per quarter hour
Guide price -
6.2IT project support
When a project is coming up and nobody in-house has an overview of the technology: choosing a provider or software, checking quotes from other service providers, planning a move of mail, files or telephony, coordinating everyone involved. I sit on your side of the table and can talk to the technicians in their own language.
You are not sold technology but given an assessment: what you need, what you can leave out, and which quote fits.
Consulting 90 €/hour
project work at a day rate of 650 €
Guide price
How you can tell you need thisWhen your website sits with a site builder you cannot leave without starting from scratch. Or when a quote is on the table and nobody at your end can judge whether it adds up.
I build static sites with AI assistance and say so openly. Shop systems and applications with user accounts are not part of this.
Education
Training providers and adult education centres (VHS) looking for a lecturer, and clubs and teams that want to learn as a group: from the very first step to their own systems.
-
7.1Getting started with IT & AI
For groups starting from zero: staying safe online (passwords, phishing, updates, backups), understanding and judging AI tools, and what happens to your data when you use them. As a group course for teams, clubs, training providers and VHS, not as one-to-one tuition.
One day for the whole group: the questions nobody dares to ask in everyday life are the programme here.
400 to 600 €/day
Guide price -
7.2Training & workshops
The next step for teams that already have their systems: operating Nextcloud, backup and monitoring day to day, IT security in the business, digital sovereignty as a basis for decisions. Half-day or full-day, with material to take away, on request on your own systems.
by arrangement
How you can tell you need thisWhen the tool is there but hardly anyone uses it properly. Or when, in your group, questions about passwords and AI tend not to get asked.
Limited places per quarter, because I work alone and want to keep things predictable.
