Omni Accounts is shipped inclusive of a single user. Should you require the ability to have more than one user accessing Omni Accounts at any one time, you will need to purchase Additional Users.
Additional Users (user 2 and above) are calculated at 20% of the software value, each.
The latest version of Omni Accounts (Version 7.11) makes provision for concurrent users, so in the event you have 15 members of staff who require their own User Name and Password, but only 10 of them require access at any one time, you will only have to make provision for 10 users and not 15 as on older versions of the software.
