Easy-to-use program once you fiddle with it awhile. Would like ability to edit text also (portions that are inapplicable rather than striking through).

Easy to use, but sometimes doesn't show exactly what I need with form being listed under another name or title (e.g. a search for DA 31 gave me the AR 600-1 132 page doc but not the Leave and Pass Form).
2015-06-13
Great. Still getting used to it though. But is very helpful indeed. When I paid for this it cost $120 but my credit card was deducted $170. I am still waiting for a response please and a refund

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.

Easy & fast customer service
I realized that my account was still active-- and I was still being billed-- after leaving my last role. I reached out to the support team on the chat function and they quickly resolved the issue for me-- canceling the transaction right away.
