What our customers say about pdfFiller

See for yourself by reading reviews on the most popular resources:
What do you like best?
PDF Filler was a Game changer for me! All my files are saved as a PDF now, I can sign documents and send back via fax or email to customers. Its also very handy with my touch screen laptop. I use a stylist pen and clients can sign just 1 time and I can use it over the course of all their documents. Clients can come in and sign without dealing with paper and copying. All I need is 1 signature and that's it!!! My whole team loves it, and I have had other Agents ask me what I use, so I have referred several of my friends to PDF FILLER.
What do you dislike?
Wish they had more fonts and color texts. Also it would be great if we could capture a signature and send it in to use. Perhaps a bigger data base for signatures as well, and more documents to be saved. Overall this program is very useful in my line of business. I use it multiple times a day, even on the weekends when necessary.
Recommendations to others considering the product:
Easy to use and saves time and money
What problems are you solving with the product? What benefits have you realized?
So much less paperwork! Saves time, money, paper and ink. 90% of my documents are saved on my computer. So no more bulky filing cabinets and paper records. Less $ on ink, and paper which is very expensive. Its actually safer to save to a hard drive anyway. Very pleased with everything PDF Filler has to offer my business.

Communication & follow through on point. Only ever used Adobe in the past. Found this affordable option. It is fantastic. User friendly and an effective app. I applied for a rental with a heap of forms to fill out and now our family are living in it. I accidentally signed up for the 1year subscription. I contacted the help desk, and advised that I only wanted to use it during the trial period for a purpose and happy to pay for one month. Their reply communication was quick and on point. They summarised and actioned exactly what I requested. Only charged me $30 for the month, refunded the difference $114 and cancelled my future subscription. I would happily use this again. Thank you very much.

I had to start over, from hitting the wrong "back up", but have it okay now. I don't expect to need it again, but this software made it much easier. Thank you!
