GrandTotal rocks! If you're a freelancer who bills according to their time, the TimeLog / GrandTotal bundle from Media Atelier has no match. Both applications are simple to use, extremely well integrated with the existing suite of Apple applications (iCal, Address Book) and provide an unsurpassed feature set.

TimeLog is your time tracker, and GrandTotal takes your billable hours as well as services and tangible goods and generates invoices instantly. In addition, with very little effort you have a full featured word processor / layout editor that allows you to create handsome layouts for you invoices, estimates and account statements.

I give TimeLog and GrandTotal each 5 stars! A must have combo of applications for anyone using their Mac to track time/services/product and then generate personalized gorgeous invoices, estimates and account statements.
