This article explains how activities in Abtrac timesheets define the type of work being done, such as drafting, meetings, or travel. It covers creating and organising activities, limiting them by project or task, and how activity settings affect charge rates, helping ensure consistent time recording and accurate billing.

Timesheet Journal Lines in Abtrac let you split a single unbilled timesheet entry so part of the value can be invoiced now and the rest held over as WIP for future billing. This is useful when you want to partially bill work without writing off the remaining value. This gives firms more control over billing timing, invoice presentation, and WIP management.
