Can I charge a title transfer fee on all vehicles?

Go into the Expense section of the File menu and add a Lot type expense to be charged to either buyer or seller as needed.  You can charge this expense to all lots, all lots in one tax class or individual lots identified by lot numbers. If you separate your titled vehicles into a separate tax class, even if the rate is 0, you can create one expense entry to charge the fee on all lots in that tax class.
