Custom rates - set up as many rates as you wish. they can be simple, such as 5 dollars an hour, or complex, such as a base charge of 25$ (as a bench fee, for example) and 10.99 per quater hour.

Pay Timer - not only does the timer show the time spent on the project, it also shows the current billing price as time progresses, rounded to the nearest penny.

History - when you click "done", you are taken to an entry screen. Enter your project or customer name, some notes, and save. you can view your history at any time. I thought it might be useful to track history, especially if your work for a customer spans several periods of time.

 ***An important note about the Rate Screen - make sure all entries are either whole numbers (ie: 25) or floating point numbers (9.95). DO NOT enter characters or other symbols into these fields (ie: $, a-z, etc) or it will not calculate correctly. It will take the value, but the calculation will not work.
