Hi Peter In the ECT Admin -> Order Stats page you get to filter by state but it won't separate by client I'm afraid, no. You can also dump the orders in the ECT Admin -> Orders Admin page and that would include the client ID. But from that I think you would have to do something pretty fancy with Excel to get the report you are looking for.
Orders Admin View Orders Select date range and press Search Then "Please Select", "Dump orders to CSV file" Open file with Excel and format In Excel select range and Data Filter
