Hello Jon and Josue,
I am quite surprised about the expected training time of 6-8 weeks as mentioned by Laurie Hart. I would be suspicious of the usability of any program that takes that long for training.
We have been using EZ Claim Premier and have been quite happy with it. We have needed no formal training. When we were exploring billing options 2-3 years ago, we spoke with one of the founders of EZ Claim when my biller had some concerns about the useability of their then current program, Advanced 8. We were then told of their new program, EZ Claim Premier. Based upon suggestions that my biller made, EZ Claim Premier was tweaked, and that is what we use. Claims are then exported to ZirMed with which EZ Claim Premier has a bidirectional interface, including "auto posting". My part time biller says that she prefers EZ Claim Premier to many functions in eClinical Works. I hope this is helpful.
