Love the app! Overall I really like the app and it has been quite useful for me as a realtor =) Great way to fill out forms and make your own fillable master form. I have had a hard time figuring out how to easily share and send the form you want and the notifications when you receive it back. Wish I could save the docket in my own files

easiest way to fill forms! I like it and I recommend it to anyone who works with Forms that cannot be edited using another softwares. In my job we need to complete a LOT of forms (we are a law firm specialized in tax and corporate law so we need to complete a lot of forms that come in PDF format) and some of them doesn´t allow us to make any edit in the regular PDF program so PDFFiller is our salvation. It is super easy to use and it allows you to edit the entire document using only this software. You can add text or even delete parts that you don´t need. It is a software that doesn´t require any effort to understand because everything is as simple as upload the document, make the changes and save as pdf or print the document. I use it every day and I find it very complete for the things that I need. You are not able to use it in several computers, so if by mistake you open your session on another computer you may loose your work.

One of the best customer service I’ve… One of the best customer service I’ve ever experienced !! My account had a monthly subscription which I thought I cancelled after the free trial but it didn’t seem to work. So I wrote them an email and within minutes they responded and took care of my issue and instantly refunded me the payments for the last 2 months in which my account has been subscribed. I’ve dealt with a lot of customer services over the past year and none has been so quick in responses, friendly and efficient in the same time. If I need a pdf service again, I’ll surely go to them. Thanks a lot & Best wishes Chris
