The program is very user friendly. Would like the opportunity to test more documents before sending to clients, so I can see what they are seeing when they receive notification to sign.

What do you like best?
I enjoy the way PDF is easy to use and allows us to send out documents quickly. We operate a few different locations remotely and we are able to send out important documents require signatures in less than 5 minutes! Support is great when needed but we seldom have any issues.
What do you dislike?
There are not many issues with it. It would be nice to be able to copy/duplicate documents prior to merging so we do not have to upload them once again.
Recommendations to others considering the product:
If you work remotely, I highly recommend this program. We love being able to email employees and clients in a matter of minutes for documents requiring information on their behalf.
What problems are you solving with the product? What benefits have you realized?
We are solving travel time and time with paperwork with all of the documents be readily available with just a click. Prior to PDF, we were having to meet with new employees for paperwork. Now, we are able to email them and have them sent back for processing. Our time is being used in a for efficient manner.

Excellent cloud based software that I am able to use on any computer! Easily able to share between documents that are signed between multiple people. I love that I am able to use the software on any computer or phone with ease along with signing PDF documents! I would like if I could create boxes easier that were adjustable fields rather than just having a single section.

Have used it to fill out two forms and was very pleased with the experience. The only problem I encountered was being unable to expand the circle. May be due to my not fully understanding the program's capabilities.

Fast, helpful assistance from their support team I forgot to cancel my subscription with them. The money came out unexpectedly, and I was honestly pretty worried because it was the full year's subscription and I have had issues with internet companies not wanting to refund subscription fees in the past even when I asked for it immediately, without using it during the period I asked for the refund for. PDFFiller was great, though. I emailed them early this morning (late for me) and woke up to their response, which was that since it was less than 24 hours after the payment came out, they were able to just void the transaction. Assuming my bank is cool about it, I'll have my money back today.5/5 Do trust.

Ny experience was good but I only have a need for the... Ny experience was good but I only have a need for the form I used maybe once a year. So I will probably be canceling my month to month once I am sure the form I needed has been accepted. It would be nice if you had an option for a subscription that was based on usage rather than on time. I might then sign up for a longer term commitment if I wasn't being charged every month but rather on my usage. My experience with your product was that actually filling out the form was user friendly but it was a form that had a continuation sheet and figuring out how to use several continuation sheets was not intuitive and I ended up filling out several different form continuation sheet pages and then had to combine all those multiple forms into one document in order to get what I needed for submission to the court.
