This has been very helpful and affordable. Please make sure that my credit card is only charged one time. Initially, the processing would not accept my card and I have entered this card for the same Monthly subscription approx 3x's. Please make sure that only one monthly fee of19.99 is charged to may account. I am not in aposition right now for excessive billing. I am looking forward to this being a valuable working tool for my Business. Thank you

I am new at this point. so far all is working fine. On the few I've used the program with it has been smooth and the people signing have liked the ease of use

I had some trouble learning to use it and directions aren't consistent. Your Help area tends to be more sales pitch on what can be done in a field with no directions. I'm very grateful for availability of the service though I'll drop it once I have my house sold in a few months

I like using the program the only downfall for me is unless I pay more for the subscription I'm not allowed to use the premier options. That is my opinion It's already expensive for me since I really only use it for tax returns.

What do you like best?
I use it as a healthcare EHR. Very convenient.
What do you dislike?
I only really have one complaint. When I use it to fill my PDF files, the pop up bubble gets in the way after I click a box so then I have to click somewhere else to see my next option.
Recommendations to others considering the product:
Great.
What problems are you solving with the product? What benefits have you realized?
Send to sign is convenient. Send to fax is also nice.

What do you like best?
I love that the physician can dictate the form to me and I can easily load the form and type it up for him. He is extremely busy and needs to fill these forms out on his own time. Now I can do it for him saving him the time to focus on face to face visits with his patients.
What do you dislike?
It is very new to me, so I am uncertain if there is anything at this point I don't like, as I am unfamiliar with a good portion of the program. But what I have used thus far is great!
What problems are you solving with the product? What benefits have you realized?

Good value for price When using the offer for roughly 40€ per year, PDF filler is a no-brainer when you need to fill in several forms a year for your household / family (e.g. insurances, real estate, etc.)

I apparently didn't understand the subscription options either, like other reviewers. But after seeing unexpected charges on my CC statement I contacted them and they immediately reversed the charges. Efficient, professional, no problem. I think the subscription charges/contracts could be clearer, but on the other hand I was moving pretty fast so maybe it was my error solely. Anyway, no harm no foul. The product itself worked fine. I have no comparison so all I can say is it functions and got my job done.

In situations like this, you can add comments to PDF documents online using very simple tools. pdfFiller's simple but powerful document editor allows you to add comments anywhere in the document.
