Very convenient the only thing I would like is to have different offers for a fax number. I barely use faxes and I would love to use this service. Can you have another fax payment offer?

What do you like best?
The upside is that it's very efficient and expedites completing forms effectively. I have used other software and didn't find them to be easy to navigate or efficient.
What do you dislike?
The downside is that sometimes the text doesn't align when filling in forms I have to complete from other service industries. Also, when PDFfiller is the default PDF it does not print without having to refresh several times.
Recommendations to others considering the product:
This software is really good and does make my administrative work easier and less tedious. There are some quirks but when I have experienced them, the support received was expedient and exceeded my expectations.
What problems are you solving with the product? What benefits have you realized?
It has really helped me to complete the necessary documents in a timely manner when there are no glitches. I love the easy access to my documents when completed.
