The Marissa Holiday Park at Lake Dümmer accommodates up to 2,000 guests and operates several outlets – including restaurants, a spa, an indoor playground, and other facilities. The complex accounting structure with many business areas was previously managed using DATEV and Excel. This led to high manual effort, lack of transparency, and limited scalability.
TSO-DATA implemented the project using the PowerStart concept – a standardized implementation methodology for Microsoft Dynamics 365 Business Central Online. This approach enabled a fast, resource-efficient rollout while ensuring high process reliability.

“Business Central was on our radar. To even determine whether the software was suitable for us, we first went through a process analysis with TSO-DATA. That means we looked at what our actual requirements were, and in the second step, we launched a demo version on-site.” — Thomas Beifuß, Marketing Manager, Marissa Resort
“Compared to previous systems, the biggest advantage is that we can now work online in the cloud. […] We were already in full operation when we made the switch. That meant, of course, there was a certain time pressure. And I have to say, TSO-DATA didn’t falter at all. On the contrary – they delivered excellently right from the start. […] The collaboration with TSO-DATA worked well from day one. Everything that was promised was delivered exactly as stated. And we’re simply looking forward to the future with the whole team – to the second park and everything else we have planned.”
— Thomas Beifuß
A project that demonstrates how digitalization succeeds in practice – efficiently, collaboratively, and with a future-oriented approach.
The complexity of accounting across many business areas – from the spa to the restaurant – required a centralized, cloud-based solution.
Microsoft Dynamics 365 Business Central Online, implemented using the PowerStart concept by TSO-DATA.
Due to its scalability, cloud capabilities, and the ability to centrally map all accounting processes.
Despite ongoing operations, the system was implemented quickly thanks to a structured process analysis, a test environment, and close collaboration with TSO-DATA.
Real-time data, location-independent access, automated processes, and a future-proof platform for further growth.
