See for yourself by reading reviews on the most popular resources:
extremely convenient and fairly easy to use, but i need to find time to sit down and learn more features other than just filling out forms and signing them. I think the vvalue of a yearly subscription is very good.

It is a little bit confusing on how the program works. I have been trial and error learning so far. It would be nice to get more direction and not just comment bubbles.

A feature that is critical to my business broke on Friday. I was able to interface and get updates about the fix over the entire weekend and had the problem solved by the dev team before Monday morning. Awesome teamwork from the folks at PDFiller from end to end. Highly recommend.

What do you like best? I love the fact that we can collect uploads AND money through filled PDFS What do you dislike? The entire site is very confusing and we have a hard time understanding where our active sheets are located within the site. We see things like "documents" and then we make a new template ... then lose which template is live and which one isn't. I also don't care for the fact that we cannot choose to have ZERO color in the field that the customer sees for filling in and I would love to be able to disable the "lock to grid" feature that is clearly on at all times. Recommendations to others considering the product: I recommend reading through the site, reading through all the tutorials you can and getting very organized about what you are going to do before getting started. What problems are you solving with the product? What benefits have you realized? We no longer have to deal with faxing our documents to customers to fill out, sign and fax back. We just tell them to go to our website . They are also so much more likely to complete the entire process including sending us pictures that we require and we no longer lose the pictures or get confused as to where everything is.

Free trial review I'm a student and used the free trial. It was quite easy to use. In addition to that, I forgot to cancel my subscription, but they had an online chat that handled that quickly and efficiently which was very appreciated. Overall a good experience.
