qcadoo MES is a server web application. This means that it's not trivial to install but once you install it then everyone in your local network will have access to it through a browser.
The installation process requires some basic technical skills. Please read the Installation Guide if you need step by step instructions how to install qcadoo MES in to your LAN network.
If you would just like to use qcadoo MES and not worry about the system configuration, updates and backups then we recommend buying a hosted version from Qcadoo in the Software as a Service model (called SaaS in short). Please see the How to buy page for more details.
