No, I think its a good program. Just a few things I need to learn how to use. Although, it's a bit costly, I would like to keep using, but it may be expensive for my business.

i have had a great experience so far it is much easier to file medical claim forms than having to buy that specific software i like how easy it is to import documents. I also like the ease of sharing, printing and storing documents Really the only thing i do not particularly care for is the difficulty adding the individual box for editable fields
