Boese VA Case Study
From over €1,000 to under €100 monthly – 90% cost savings in team communication
The Challenge
The online agency Boese VA used Slack for internal communication. With over 100 active users, costs rose to over €1,000 per month – more than €12,000 annually.
Each new team member increased fixed costs further. Additionally, dependency on the provider's pricing model and lack of customization options.
Main Problems
- •High Costs: > €12,000 annually just for communication
- •Scaling Bottleneck: Each additional employee creates extra costs
- •Vendor Lock-in: Dependency on Slack's pricing model and features
- •Limited Control: No own management or customization

The Solution: Self-Hosted Mattermost
WZ-IT deployed a self-hosted Mattermost instance based on Proxmox virtualization and Hetzner infrastructure.
The solution was precisely adapted to the company structure, with automated backups, monitoring, and high availability.
This created a flexible enterprise alternative – secure, scalable, and cost-efficient.

"With Timo and Robin, you're not only on the safe side technically - you also get the best human support! Whether it's quick help in everyday life or complex IT solutions: the guys from WZ-IT think along with you, act quickly and speak a language you understand. The collaboration is uncomplicated, reliable and always on an equal footing. That makes IT fun - and above all: it works! Big thank you to the team! (translated) "
Timo and Robin from WZ-IT set up a RocketChat server for us - and I couldn't be more satisfied! From the initial consultation to the final implementation, everything was absolutely professional, efficient, and to my complete satisfaction. I particularly appreciate the clear communication, transparent pricing, and the comprehensive expertise that both bring to the table. Even after the setup, they take care of the maintenance, which frees up my time enormously and allows me to focus on other important areas of my business - with the good feeling that our IT is in the best hands. I can recommend WZ-IT without reservation and look forward to continuing our collaboration! (translated)
We have had very good experiences with Mr. Wevelsiep and WZ-IT. The consultation was professional, clearly understandable, and at fair prices. The team not only implemented our requirements but also thought along and proactively. Instead of just processing individual tasks, they provided us with well-founded explanations that strengthened our own understanding. WZ-IT took a lot of pressure off us with their structured approach - that was exactly what we needed and is the reason why we keep coming back. (translated)
WZ-IT set up our Jitsi Meet Server anew - professional, fast, and reliable. (translated)
