PTMS has been a huge time-saver for us, from filing returns, the assessments, tax bills — really the whole process from beginning to end. We can prepare two or three hundred returns for a state  in four to five hours, and get them out the door same-day if needed. If you did that by hand, you’d need several people on hand to be able to handle that volume!
