For FacilitiesDesk Team

Believe in what Eugene said:
Before thinking about any software write down what is required for your business.
Then ask some software providers whether they can implement what you need.

And have a close look on support on the market. Who can and will support you and the software when you use it ?
Will the software still be supported in some years ?
