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".
