Another question: on our invoices, we usually include client code and project code in the following format: 1234-4567 (1234 being the client # and 4567 being the project #). The invoice # is separate from the client-project #. Is there a way in Billings to include the information from the extra fields, that list client and project codes, on the invoice? So far, I've only found a way to include the project code (in Preferences>Numbering), but this lumps the code together with the invoice number (I can't seem to be able to even put a dash between the two), and I can't find any way at all to have the client code included anywhere on the invoice. Unless the way to do it is to manually input the client-project code into the Project Name field?

I believe the only way to do this is to edit the invoice template and add the details that you need. All of the information on Invoices (or any report) is determined by the template. Hopefully someone with more intimate experience with the report engine can expand, as I do not know enough, yet. You may wish to correspond with our support team for this question.
