Timeslips offers server-based timekeeping and billing software. This means that you must log in to your firm’s server (that you or an IT person have configured and set up properly) to add entries and generate bills. In terms of features, Timeslips seems to do what most of the competitors do. It handles trust accounting, lets you create clients, matters, and bills. Timeslips has several attorney-related features like conflict checks, scheduling, and LEDES exporting for invoices.
