The entries you make in the Customize portion of the Easy Setup Assistant will appear in FirstEdge's Preferences window. With a few exceptions, the entries you make here can be changed anytime you like using either the Easy Setup Assistant or the Preferences window. Default selections have been chosen for you so it's not essential that you complete this part of the Easy Setup Assistant. You should, however, review the default selections to be sure they match the way you do business.
If any options are unclear to you, click the Help button in the lower left corner of the Easy Setup Assistant; MYOB Help will appear with information about the options displayed.
