About us
Lisario Systems develops software and manages IT environments for small and medium-sized enterprises in Switzerland. We take on what internally lacks the time or expertise: maintaining and modernising grown in-house applications, automating recurring routines, and organising and securing Microsoft 365 environments.
How we work
We start with what exists. We read code, talk to the people who operate a system and document what we find. Only then do we describe a target picture.
We work in stages that can go live individually. Every stage has a named deliverable that you can review.
Handover
Source code, pipelines and documentation belong to you. We leave no dependency on individual people and describe operation and error handling in writing.
Languages and locations
We work in German and English. Meetings in German-speaking Switzerland are attended on site, the remaining work is done both on site and remotely.
