This is broken down into two sections "Customer information"
and "Project Information":
Customer information is "Saved" as a file, you can recall
it later so all you have to do is enter in an Invoice Number and
the Project Name. Everything else is added for you. If you create
a new Customer account then You will have to first save that information,
but the program don't know that you want to use this customer for
your next Job, so to add them to the next job click on "Click
to add Customer Information to Project".
