This program worked for me when I had to do a state specific purchase & sale agreement/real estate. All six signers lived in different states and so had to digital sign. Easy to walk them through it.

I needed to type on an older document and this program seemed like a good choice. Also, since I can pay month to month I can stop when I am finished with the paperwork and that was a nice option.

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.

Very professional and good customer support I forgot to cancel the auto renewed subscription after my free trial and they got back to me within a day and were also very responsive. I got refunded immediately even though it was my fault for not cancelling.

I am sorry…..I am having a hard time. It is completely my own fault. And that is because I am computer illiterate. So I am trying to learn this stuff for the first time completely on my own. I wish I had someone to point me in the right direction. I already tried to watch You Tube. But it didn’t quite help. I am a total newbie. Beyond a newbie even, I guess. So sad….

Very satisfied so far. Have not yet utilized the notary service but plan to do so. Very happy editing PDFs. My only complaint is that it's far too expensive for my needs as an individual. I can see how it would be well worth it for a business, but in my case, I will likely cancel after a month because I just can't afford it. Please consider a cheaper option for individuals &/or sole proprietors. That said, it's a great service -- far better than others I've used. Great job.

"Only One Solution for All Your Needs Regarding PDF Processing!!" I've had a good overall experience with pdfFiller.I would advise other professionals in our sector who deal with several forms to engage with clients. This software's ability to instantly update forms from my PC is what I appreciate about it the most.Editing forms and adding digital signatures are some of the best features.I can also choose to fax documents if I need to.When it comes time to develop and submit crucial documents, these capabilities give my small firm a professional appearance. Maybe it's challenging to align or position the text boxes correctly, but I believe that with more practice and use, I'll get better at making these minor adjustments.

I made the mistake of subscribing to a year subscription with annual price due at sign on. I only wanted to test the site and see if it was right for me. I noticed within a few hours what I had done when I checked my banking account. I got online with their live chat support. I talked to someone named *** and within 5 minutes, *** had fixed my account to only a month subscription, refunded me all my money minus the monthly subscription. My mistake, *** fixed immediately and was so nice and helpful. ***** customer support!
