Volume practices get a bad rap. People assume that just because you move a lot of clients' cases through the system, that you are doing a lesser job on the cases.
Bollocks. Moving a case quickly, or more accurately, efficiently from intake to completion is good for you (because it frees up time for more clients) and great for your client (fewer billable hours, obviously).
Of course, efficiency and volume have to be balanced with diligence, ethics, and customer service. Fortunately, we've got a few resources that can help.
