Single-User Edition is designed to meet the needs of those firms that require a minimal amount of people to handle their billing matters. The single-user edition permits only one person at a time to operate Legitigant®. This edition is good for those firms that are just starting out or have a small number of people in the office. Albeit, Single-User limits the number of people that can handle your billing needs, it does not limit the ability to track your billing as your business grows. Legitigant expands and grows with your business. Legitigant's Single-User Edition can easily be upgraded to Legitigant Multi-User to enable more users to operate your billing.
