Was looking for a fast PDF fillable form. I found it here. Even has e-sign which really makes me look professional. Always wanted to try it and now I'm glad I did.

Your guy was good - but I really didn't get the result from the program I expected. I thought it would convert to word exactly. I understand why it didn't - just makes the program less than what I had thought I was buying. I don't do this type of work often and will probably just discontinue the program.

So far it is good. Convenient for forms that require signatures. No more printing, signing, scanning and converting to pdf a gain before mailing back.

It's pretty good. There is a delay from when I type till when the text appears in the text box.Also, I don't like have each field with a help box. I know I can X it out but it gets in the way when I want to go fast. I do like that it goes automatically from one field to the next such as with the dates.

The conversion from Pdf to word was the smoothest I've seen. There are very few errors. AMAZING! After reviewing the document I noticed that the conversion dropped the letter F. If there were two f's in a word the conversion dropped one of them.

This system is amazing, but I have trouble with the 40 per month fee, but I will notify my supervisors at the business, it would be a great investment for the company as a whole.

What do you like best?
The best feature is that you can email documents to vendors and have them electronically sign them and then email them back.
What do you dislike?
I don't think there is anything to dislike. When my company paid for me to have this I felt like I was in Heaven!
Recommendations to others considering the product:
If you are having issues getting signatures with your drivers- look no further! This is it! So easy to use and send and Drivers can send the signed documents back!
What problems are you solving with the product? What benefits have you realized?
We have a lot of vendors that work outside of the office so having a system where they can sign electronically is such an awesome feature!
