It beats my hand writing. I would be nice if it did the calculations also. But you can't have everything. I'll probably be only using this for my state tax. There on line program stinks.

What do you like best?
I can sign paperwork, make changes and do it all without a printer wherever I am in the world.
What do you dislike?
There are some some glitches with the program.. for example to save a document you first have to make a duplicate of it. Also, I thought there was a way to re-number pages but that feature seems to be gone?
Recommendations to others considering the product:
Its a great program overall and affordable. I would definitely recommend it.
What problems are you solving with the product? What benefits have you realized?
I love being able to make changes to offer sign backs without a printer. Even if I'm in my office I still use it to keep the document clean and easy to read.

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!

Easy to use and has multi functions that otherwise you would need to purchase separately elsewhere.
I gained TIME, thus I was on time with my tasks, and met deadlines.
Very easy to read, highlight, insert comments (etc), insert and replace figures in pdf documents. It has saved me TIME! I love that it offers features that make manipulation of multiple files easy and fast. I also like the electronic signature option so documents look very professional.

could be better
I feel that adobe does a better job at converting PDFs. Although PDFfiller has a good trial period that you can use all their resources. I like that it has a notary with the plan you choose.
some documents don't fit what you search for. Conversion to PDF could be simple.

I had DocuSign and tried PdfFiller. A much better experience with PdfFiller. Easier to use, and less costly for the infrequent user like My Wife and Myself

What do you like best?
Ease of use and the editing tools available.
What do you dislike?
It would be great if the system would take me straight to the My Docs page at login.
What problems are you solving with the product? What benefits have you realized?
Great for needed digital signatures on contracts, etc. We also use it to edit maps we use in our business for clarity.

What is a Digital Certificate and How can I View it?
The usage of a digital certificate is a kind of authentication to keep track of all changes made in PDF files. It comes into action after the complete document is signed by the last authorized certifier.
In case the changes were made after signing the document, it will invalidate the digital certificate.
To view the certificate, one needs to open the document with Adobe Acrobat Reader. The certificate will be seen under the signature panel. By clicking on this link one will see all additional details about the signer and document itself.
