I absolutely love it. I still haven't figured out all the things it will do and how to do them, but it has been saving me a lot of time in my job. Saving me a lot of white out!

I was sold on the ability to edit anything on the document easily with PDF filler. I have the latest copy of Nuance Power PDF Standard that I used to create an editable form and I could not figure out how to edit some of the fields on the PDF doc. (I believe the source PDF file may have been poorly designed for computer input.) Anyway, I find PDF filler very easy to use--no need to convert the document to a form--just start editing with the various tools. Neat!

So Far, I have enjoyed using the software and it's ease of use. It accomplished the initial task I required, however, was disapponted when full functionality offered failed. Namely the USPS mailing feature. This caused personal business delay of service. I am interested in the use of this application for my business. Digital forms like a product trial agreement and installment payment agreement with customers is a secondary spin off that may be valuable to me. Storing signatures and document sharing is a plus. I like it's integration with Google Drive and others. I will recommend to others but st this point as a trial only.

Overall the format is excellent -- the clearest, fastest and most accessible set of URL instructions I've ever used -- EXCEPT haven't yer succeeded in getting a doc e-signed! Maybe we were missing a step. The doc got e-sent to the signer, but all he ever got was the sample doc to fill out -- but it wouldn't let him fill it out. and just kept popping up the sample doc. Even tho ' it side we'd successfully down loaded the doc - but it appears it kept downloading the same sample doc and not the one I'd sent him to sign,

Absolute timesaver
Absolute timesaver and easy to use once you are in the form.
It's an absolute timesaver when filling in repetitive forms or having to sign and email something for signature.
Ease of moving around website is a little tricky sometimes

some of the forms are the same but pdfFiller has them in different names. I keep filling out the same form over and over, thinking it's a different one. confusing.

it's easy to fill out and send wherever you need to send any important documents
it was simple, and easy to send my documents to wherever they needed to be sent. Also the signature was perfect, I didn't need to print and sign anything, it was all here for me.
