I am not very computer savvy and I am learning as I go with this new MacPro, but so far it has been a very helpful tool and plenty of help explaining how.

My only disappointment with PDFfiller was that I did not know it was a subscription based service since I clicked through a google link to a specific form. I made customer care aware of my concern and they were immediately responsive and apologetic fir the issue. Completing, saving, and printing the forms I needed was easy to learn and do.

for the most part, all of the documents that i need have been found on PDF filler. I did have to find the 2016 1099 int form on another site, but at least i found it.
This service has saved me a bunch of time by not having to type these forms on a typewriter.

Well, I just got it and I am exploring its features... Too early for me to give a feedback. I'll be able to tell you more in a couple of weeks, I guess! Thanks!

After some heartbreak at having lost the doc I was working on, the team at pdffiller managed to retrieve it for me. All those tears later, I am ecstatic to have my hard work not be for nothing!

A safe way to fill forms
I wish they had an option for screenshare set up support. Though it took awhile to learn, we are so grateful for what it's allowed our company to do!
LinktoFill allows us to send out one link and receive back filled PDF's instead of uploading over and over and sending back and forth to gather missed info.
The site is hard to learn and takes a bit to get used to.

good enough but I am being billed $30 and $30 for this month October alone and I only have one license. Just me. I need this corrected immediately.

This product is very easy to use and I am impressed with the various toll available to make the changes to the PDF files.The service and backup provided by the support team is excellent. I cannot fault their response times (within 20 minutes of my email) and they were attentive to my concerns and resolved the invoice issues immediately. Totally would recommend this to anyone.
