After contacting customer support, I was told that certain web browsers are more compatible than others in completing forms. Once I changed from Mozilla Firefox to Chrome, I was able to complete all fields of the form without problems. But it would have been helpful to publicize this information on your website so that much time was not wasted.

I love the ease of completing the forms. I have completed over 30 documents and each one was easy to find in the library once I put the document number in. I love the fact that you can choose which pages you would like to print. Another great feature is it saves each document automatically and you can save the completed document to another device.

The card reading company kept declining… The card reading company kept declining every card I had even though they were all in good standing. Customer Service (online chat) tried several remedies. Still did not work. I needed to print the document I completed. Customer Service gave me a one time free print so I was not in a bind and will try again tomorrow from different computer to actually purchase the service!!Thank you!!

The product is very good and it works very nice and... The product is very good and it works very nice and it's very easy to comprehend how to use it, but the way you have the purchase setup I feel is very misleading I signed up for the month the month payment and you took a full year out of my account I did not like that that is why I would never recommend your product to anyone want to use because you can really mess up a person and you could be taking money that they could not have to be taken at the time. You need the fix your payment process area or you will lose other customers like myself because I did report it to the Better Business Bureau cuz I did not appreciate that.
