Once I became familiar with the input it was pretty easy to use. However trying to Print was difficult. The on-line help didn't suggest using the DONE button!

Locating forms is a little… Locating forms is a little slow/complicated. Also would like to be able to save information that will be repeated on other fillable forms.

Makes PDF files easy to manage! It makes it easy for our employees to attain and manage pdf files on the go. It saves every time and is easily accessible. There are times when it takes a few times to bring up the document. This may just be an internet issue on my end.

That i was able to fix and remove… That i was able to fix and remove unwanted documents to send just what i needed. The fact that I can fax without having a big machine to do, matter of fact that is one of the reasons that I decided to use pdfFiller. You make filling out important documents easy and able to sign by uploading just a picture of the signature needed. However you could make it easier to be able to create a fax sheet more personal. The one on the website is okay but not personal enough. Maybe I will think about doing the annual thing let's just see what more I can learn to do with your program. thank you for making it so easy to send important documents from the comfort of my home office without having to pay someone else to fax for me

Amazing customer service I tried it a while ago, and something went wrong when cancelling my subscription (maybe me...). I got charged for the service anyway, but then asked for a refund. The support team was extremely responsive and useful, I'm really happy about their service. Excellent!

Don't let the name fool you, it does so much more than allow editing I use pdfFiller to sign agreements when I'm traveling and don't have the version of Acrobat where you can sign, on my computer. I actually like pdfFiller much better, because it allows me to edit things that Acrobat does not. I've utilized several of the templates that have been very well laid out. I was pleasantly surprised to see all of the templates and formatting options that are built in to pdfFiller There is really nothing not to like. I don't use some of the features, because we don't need them, but I can't say it's missing anything or has any issues.
