On The Job is an application designed to help you track your time and expenses, and bill your clients by easily and quickly creating professional invoices. On The Job is straightforward and easy to use letting you focus on what's important.It all starts with Clients. Track client information such as names, addresses, and hourly rates. Create fully customizable settings for invoice number generation. Clients contain Jobs and Invoices, both of which can be organized into folders.

Jobs can contain four basic types of items: Timed, Fixed Cost, Quantity, and Mileage. These items correspond to line items on an invoice.Timed items track time in timing sessions. A new session is added each time the timer is run. If you need to quickly add or adjust times, you can use Quick Add (for those times a client calls you at one in the morning and the last thing on your mind is starting a timer) and Quick Modify (in case you forgot to stop the timer when you started working on something else).
