Small to medium-sized law firms can greatly benefit from Amicus Attorney. It provides a central repository for all case management as well as calendaring between employees and their assistants. Document automation can also greatly save employee time (requires additional configuration and setup).
It is very helpful with tracking our time and allows us to start a timer when working on a project to keep an accurate log.
Since it is web-based, it can be used to log into email and contacts remotely, which I have found extremely helpful on several occasions.
The phone messages are also very helpful. Amicus will populate the caller information with the caller's contact info (if stored on our system) and generates an automatic email to the individual for whom the call was intended.
Subscription based only, formerly allowed "ownership" of software with annual maintenance agreement. Software has moved to a monthly subscription where one "leases" the software from the owner, Abacus.
Software stability, can occasionally have server-level issues that require cycling of services in order to restore connectivity.
Exchange calendar sync does not warn users that sync is not occurring. After updating Active Directory password, password needs updated in Amicus Attorney. Problem being, it does not remind / alert if the synchronization is not occurring.
In the time that I have been with my firm, we have not used any other comparable software. As a result I can't compare it to anything else that is out there
