Some further pre-purchasing questions.
1.
You are offering an Ultimate Site Version for $799+. What does the "+" means? We are about 13 users here. The site version would save money for us.
2.
How many licences do we need, when a user would like to access to its calendar in the office and later also at home (from another computer). In such case (without syncing over Google or MS Exchange) the user would logging-in via VPN to the company network. After obtaining a privat IP from Company LAN, VueMinder at home would get access to the MySQL server within company LAN for syncing.
3.
Now a provocative question.

In your FAQs you wrote: "VueMinder Pro and Ultimate are licensed per individual user. A single user license can be installed on any number of computers where you (or a family member living in the same residence) will be the only user. Other users will need their own licenses. ..."
What happens if we would purchase only one licence, install it on 13+ computers and create only one shared calendar, called e.g. "Company". Every user is simultaneously using the same shared main calendar "Company" on its single computer.
Further, when needed, every single user is able to creates it's own "sub-calendar" below the main "Company" calendar. I mean I could create as much own sub-calendars as I want (which one licence) which could also be shared.
4.
Do you intent to integrate the CalDAV and CardDAV protocol in future for getting access to the Calendars by mobile devices, maybe over a server daemon which holds permanent access to the MySQL database. We do not have a MS Exchange server in place and wouldn't like to share our data with Google.
Greetings
