Professional services automation (frequently abbreviated to PSA) is software designed to assist professionals, such as lawyers, auditors, IT consultants and other professionals who work on client projects. In its simplest form, PSA software may offer only timesheet systems (including expense reporting and project management). However, in their most robust incarnation they can also include customer relationship management (CRM), resource management, opportunity and knowledge management.
