time and attendance time and billing software time sheet TIME AND ATTENDANCE Tracking within Abak is centered on projects. Because billing for special projects is an increasingly important aspect of most firms' profitability, this project-centric tracking is a powerful tool for better monitoring of time and attendance expended and dollars invoiced. All of the time and attendance you enter can be billed in total on a client-by-client basis or you can opt to select time by project. Few categories of CPA applications have changed as dramatically over the last few years as practice management, the group of applications that include time and attendance, but go well beyond the jobs of capturing time and preparing invoices.
