A very good and friendly in navigating the fields. Need improvement especially in the telephone number field and user address died of CMS 1500 of 2012 and UB04. Unable to include the three digits telephone area code. Address field too small to contain full address including zip codes

Great Product! I love this software; it has been invaluable. I have used it to fill out job applications, insurance, medical & school documents. I'll continue to use it. It is very easy to upload documents to this software. Editing is user-friendly even for those not technically savvy. I like that I have many options in saving or exporting my finished document. Also, I like that my previous documents are saved because there has been more than once that a document has been lost or needed again. I have been saved by the fact that PDF Filler has the previously used document saved. I have not found anything I really dislike about this software. I'll be honest in that I'm not crazy about the price but I have found this software so helpful I have been using it for over two years now. I've recommended it to several people. I did not rate the customer service because I have never used it. I guess the fact that I've been using this for over two years & never had a customer service issue speaks for itself.
