Need to add a new class for another location

First you need to make sure that the Class Tracking feature is turned on.  Go to Edit.  Then select Preferences.  Then when that window appears, click on Accounting (along the left side of the screen).  Then after you do that, click on the Company Preferences tab in the upper middle part of the screen.  When the next screen appears that displays the Company Preferences for Accounting, check the box that says "Use Class Tracking".  Then select OK.  Now when you go to write a check or enter a bill, there will be a 'class' box.  When you type in the title you want to assign that transaction to, Quickbooks will automatically prompt you to set it up.  If class tracking has already been turned on then you can go to Lists and select Class List add new classes.
