Wow, I am just testing the functionality of this system. If it does what I think it can its like having a personal secretary/ administrative assistant. I will gladly pay the premium for the service. My one concern, I want to make sure the is confidentiality and protection for the documents I'm transmitting as they are confidential. These days identity theft and misuse of personal protected inforamtion is critical so, you're assurances my site is secure and my documents I choose to fax and mail from PDF filer are not being inappropriately accessed by PDF filler employees is good to share. I like the email code you require for me to log in, that gives me security. I would like to know that when "chatting" with your team, they can't see my actual documents, just my account. I have no reason not to believe your site is secure, but just sharing. I am considering purchasing a small business, I would use your service daily and would like to be able to "buy up" credits for additional fax capabiltiy. Great service ! I've already referred your system to at least 4 different companies including the mortgage company I'm working with on the purchase of my business who has stated they will refer their clients to it. Thank you.

I am very grateful for this software that came into my life just as I needed it. It is easy to use and I love how it saves my work automatically so I do not LOSE it. Some many times with website document editors online, I have been been disappointed after working for hours on a form, to have it just disappear. NOT HERE. Every single time the system has gotten disconnected due to WIFI issues at my home or because the PDF filler webpage needed to refresh, ALL MY WORK was SAVED. Love it.

What do you like best?
I have tried many signing apps and software and this one is by far the best in terms of ease, flexibility and speedy workflow.
What do you dislike?
Maybe it is just something I am not figuring out...but the orange box prompts on some documents get more in the way sometimes than help.
Recommendations to others considering the product:
Keep up the good work!
What problems are you solving with the product? What benefits have you realized?
Signing of all contracts, invoices, and P&Ls. I love the ease of storing documents I most commonly use to transmit has and easy to clients with a simply date update.

What do you like best? What I like best is that I can upload my documents. I then edit them as needed. I can print, save, and fax all from within the application. The system is user-friendly and easy to navigate. What do you dislike? I cannot pinpoint one thing that I dislike. I use this application regularly. It fits all my day-to-day needs, whether that is business or personal. The fee for business users could have a certain percentage off. What problems is the product solving and how is that benefiting you? There is a lot of signing documents in the business I work in. With this application, instead of printing the paper, singing it, scanning it back into the computer, then exporting it where it needs to go. I can sign via text and, from there, can ship where it needs to go.
