In a quickbooks data file for a new client, the group item is being used on invoices with accounts rather than items.  It is very odd.  I believe this to be incorrect, as when the invoice is created there are certain account lines that get summed in the invoice.  But the accounting effect of this is not revenue,  but a contra expense transaction?  I can add more description if needed.   I believe the "group item" should be used with grouping "items"  not expenses on the expense side of the check.  thanks Lisa
