What do you like best?
The ability to easily sign documentation, and have these pages sent directly to their intended recipients from one location. That it is cloud based and it's easy ability to integrate with our existing customer support solutions and office365
What do you dislike?
Their is very little to dislike by this platform, but the ability to add multiple sources for example if I want to print and email a copy of a document at once would be good. It's quite clunky at the moment, requiring us to save and then go back into the system and request print when we need a hard copy of the documents.
Recommendations to others considering the product:
Very easy to use, and very competitive pricing. If you compare this product with the more expensive competition it does all of the same things but at considerable less cost. I'd highly recommend this product to anyone looking at obtaining signatures or sharing documentation via the cloud. The control panel is very innovative and makes requesting/creating documentation very easy for end users.
What problems are you solving with the product? What benefits have you realized?
We have literally saved countless reams of paper and many man hours through using this software. Documents can be electronically signed, and sent and you can even request a signature for documents. Collaborating with staff and end users is made very easy through the user interface that is provided and you can easily see which users have signed the documentation or even request reminders when documents remain in a pending state.

Customer service is A1!
Wow! Customer service is A1!I needed to fill out some forms for an outfit, a one-time thing, and signed up for the trial month.Later in the month I tried to cancel the trial period before my credit card was charged the $20, but I forgot which email account I'd used to sign up, so I was unable to log in to my PDFfiller account.Today, when I received the email saying my credit card was charged the $20, I was able to contact PDFfiller since I now knew which account I'd used. I contacted them via "Contact Support" in their website and explained my situation. OMG! When it said I should receive an email in 20 minutes or less, I was thinking, "Yeah, right!" but it was literally only minutes before I received an email saying they would be glad to cancel the subscription and refund my money.If I ever need this type of service on a more regular basis, I will definitely be signing up with this company!

very happy so far, awesome program for what I'm doing, fairly easy to navigate thus far, the real test will come in a few months when I'm using it a bit more to its potential.

Easy to edit.
I had a little trouble completing the form correctly but it was my fault. I went back and made corrections easily and all seems fine.

useful, easy, accessible, and most of all which is rare in these cases transparency ( love that you show days left of trial rather other free trials that sneakily start charging hoping you forget when trial ends and not respond)
