One feature that is lacking from MYOB is the abillity to have a Head Office account so multiple customers can have their invoices combined onto one statement.
for example one of our customers ...
MYOB does head office billing by using the delivery address. Set up cards for the head office and all the branches you need. Then charge the invoice to the head office, and select "other card" in the drop down for delivery address and put thison the invoice. This tells the head office where the goods were sent.
Hope that helps.
