As a specialist in preventive fire protection, a specialist in preventive fire protection, smoke and heat exhaust, and ventilation technology now digitally generates approximately 10,000 inspection and maintenance reports per year, manages over 2,000 individual systems and components—down to the drive cylinder—and connects both Microsoft Navision and Personio to SIMPL.
Specialist in preventive fire protection, smoke and heat exhaust systems, ventilation, and daylighting technology. One-stop service for planning, installation, and maintenance. Founded in 1991, headquartered in Düsseldorf, with additional locations in Munich and Heidelberg.
Gathering system history before each job from project files, paper logs, and colleagues’ memories. It’s difficult to get information to the technician and back to the office after the job is done.
Over 2,000 individually recorded assets and components, approximately 10,000 digital reports per year, with Microsoft Navision and Personio automatically synchronized. A single source of truth for the office and field staff.
Our systems have been in operation for twenty years or more. It’s crucial that we know at all times what components are installed and what work was last performed on them. Today, this entire history is stored in one place, and an inspection report is generated in about five minutes right on site, rather than in the evening at a desk. With 10,000 reports a year, that makes a huge difference. The fact that the ERP and HR systems are integrated saves the office staff from having to maintain the data twice.
aTmos manages systems that remain in operation for decades and must be regularly inspected and maintained. These include smoke and heat exhaust systems, ventilation, natural lighting, and heating—often combined within a single facility and distributed across a customer’s multiple locations.
Before SIMPL, three things in particular took up a lot of time. First, gathering the system history before each service call—from project files, paper logs, and colleagues’ memories. Second, figuring out how the technician would even get this information for the job: what’s installed, what work was done most recently, and what tools he needs to bring. And third, the process of getting reports, results, and documentation from the job site back to the office.
At the same time, the business side was managed in Microsoft Navision, and the HR side in Personio, the system for HR management, leave tracking, and time tracking. Anyone planning an assignment needed information from both systems and had to manually combine them.
aTmos has been working with SIMPL for about two years and now uses the platform in nearly every aspect of its service process, from the asset master data to mobile documentation to integration with surrounding systems.
The equipment master data was rebuilt from scratch in SIMPL rather than carrying over old structures. Today, aTmos manages over 2,000 individual pieces of equipment and components there, organized exactly as they are actually configured on-site: from the facility to the individual hall and down to the drive cylinder. Each level contains its technical data, documents, and history. This is the installed base upon which predictable after-sales business is built.
Inspection reports, maintenance reports, and service reports are created right on-site using a smartphone or tablet, complete with photos and signatures. The results are linked directly to the correct component and are immediately available in the office. No typing, no scanning, no searching for documentation from three years ago.
Customer and order data is imported from Microsoft Navision into SIMPL. Quotes, orders, and invoices remain entirely within the ERP system, while the entire service process—from the initial inquiry to the final report—is handled in SIMPL. Both systems use the same data, eliminating the need for duplicate data entry. We use the same integration for the other Microsoft ERP systems, from Dynamics NAV to Business Central.
Personio, aTmos’s HR system, stores employee master data, vacation requests, sick leave, and time tracking. These absences are automatically synced to SIMPL. The scheduling system automatically determines who is actually available without any manual intervention. Data continues to be maintained in only one place—namely, where the HR department works anyway.
SIMPL does not replace either the ERP or the HR system at aTmos. It connects the two and fills in the gaps where they fall short: on-site service.

From scattered information about plant assets, over 2,000 plant assets and components were recorded
From the production hall to the individual drive cylinder—each with technical specifications, documentation, and history.
Paper records were converted into approximately 10,000 digital reports per year
Created where the work is being done and saved directly to the correct component.
Separate systems were consolidated into a single data repository
Microsoft Navision and Personio automatically sync with SIMPL, so no one has to enter data twice.
Reactions Turn into Predictable After-Sales Business
The installed base serves as the foundation for maintenance contracts, retrofits, and upgrades.
High level of acceptance among technicians
The app is used in everyday life; it isn’t bypassed. That’s the only way to ensure the data remains accurate over the long term.
Reports generated annually, digitally on-site rather than on paper.
Equipment and components recorded individually, from the production hall to the drive cylinder.
Microsoft Navision and Personio are automatically synchronized, eliminating the need for duplicate data entry.
