As an Administrator you can edit current, hide, rename or delete add new Expense Types in seconds – as soon as they are created they are available for use. Simply select “Settings” > “Expense Type” tab, here you are presented with the default list of expense types.  

Note: Some Expense types are used to default against merchant categories codes in transactions from cards so please be aware if you delete these some reports will no longer map to the appropriate category.  Further some finance systems pre define the expense types during configuration.
