difficult to sign and other parties not knowing the software, I feel I need to be cautious. Too costly for a novice one time user. Overall, it has been helpful. thanks!

To Whom It May Concern,
I need to let you know that I jumped the gun on submitting my prior severely bad review. Knoll G ended up figuring out the issue and assisted greatly in resolving it. She had much more patience than I had as I had been trying to figure out where everything had been changed to from when I used your site the year before. After 4 hours of much frustration, Knoll G saved the day. I would like to ask for you to somewhat disregard my initial review. I only say somewhat because I feel that the site had such a huge change from last year's "easy to use" formatting. I never needed to use support help. That said, I would like to praise Knoll G. She never gave up even when I did. Huge THANK YOU for not giving up Knoll! You're great and I hope you get some sort of reward for going above and beyond.
I would also like to add a technical note...I don't know how everything is viewed on the companies side, but it was very difficult to work with support in terms of the chat box. Every time Knoll G gave me a direction to go and I went (which means the screen changed), I would lose the chat box and had to wait for Knoll G to type and send me something before the box would reappear and then I could respond. It only added to my then current frustration so your site coders might want to look into that.

Works as Advertised
I was able to use it to auto fill my PDF forms using Zapier and the PDF's automatically save to my Google Drive
Some of the functionality is kinda vague as to what it actually does.

A very useful tool for paperless office work.
It helps me to save paper and electricity by not using physical papers for my office documents. I do most of my office work online only with the help of this software.
It allows me to get e-signatures on my office documents. Being a cloud based program it allows me do all my pdf related work online only.
I don't find auto save feature in this application. I had to lose my unsaved work many time when I closed my system accidentally.

Once I figured out the system it was…
Once I figured out the system it was not difficult for me to complete this process. Thank You for streamlining this process.

It is really good
It is really good, I hate forms, who doesn't but this made the chances of my cat getting kicked much smaller.
No animals were hurt in the making of this review.

Cancelled my subscription within the 30 Trial Period and was charged the following month. Had an online chat and they issued a refund with no questions asked. Good Business!

I really like the capability of downloading forms, completing them and signing to send off.
I wish I did not have to log in each time. That would be a great plus as I work for several clients and need the quick ability to do a form and send to them.
Thank you Alice

It met what I needed but there is a problem with text fonts. In my case I needed a specific font and I couldn't find it, it would be interesting if it were possible to include a new font.
