Do you also support software you did not develop?
Yes, after a technical review. It clarifies the state of the code, documentation and infrastructure and which risks exist. On that basis you receive an honest assessment of whether a takeover makes sense and what it costs.
Where is the data hosted?
In data centres within the EU. The providers and sub-processors used are disclosed, and a data processing agreement is concluded where required.
Is there a service level agreement?
For products such as SmartShelf the SLA is published. For individually supported applications, availability, response times and maintenance windows are set out in the support contract.
How are support costs calculated?
Usually as a monthly flat fee for hosting, updates, backups and monitoring, supplemented by an agreed hourly rate or a quota for extensions. The model is adapted to the scope of your application.
What happens if I want to switch providers?
Source code, data and documentation belong to you and are handed over in full when switching. An orderly handover to another team is part of how support is understood here, not an obstacle.
