Hello, 

Thank you for attempting to help.   Those steps do not solve the problem I am having.  Every one of our customers has their own account number or "customer:job" number.  I did not have to create any custom area for this in Sales Orders or Invoices and would not want to do so.  

I would just like to select a bunch of sales orders and click Invoice the selected sales orders on one Invoice?  Is that possible?  I know if one customer has multiple sales orders I can add them all to one Invoice.  I need to find a way to do this for multiple customers with one Invoice each. 

Thanks!
