I've been running a small W-2 service for about 7 years now for about 10 clients. I just pull their PR data to my server, convert to the latest version of MAS and run with it. I started doing this when the old PR W-2 forms were a PITA to align and print. Just faster to do on my side. Plus with electronic reporting, I would upload to the SSA for them. Now with Aatrix, it is so easy, I am thinking about just sending blank paper to the clients next year and let them do the work.
