Excellent program, way easier then DocuSign Super easy to use and if you need tech support they are there for you. Its very easy to use and very informative. A couple of clicks and you are done. Tech support is great as well! It would be nice to get an email when the client opens the contract I send, rather then always having to check

Easy, reliable and very effective Makes completing forms easy and professional. Easy to navigate, easy to find and upload forms and easy to send/save. the only negative thing I could say is that I would like to have the font a different size and I have been unable to fit it correctly in some spaces.

PDF Filler-Sign, Send and Relax As a user of PDF Filler, I have found I can do so much and I try to when put to the challenge. I have many ways to adjust files and docs to my needs or the needs of my Agency or Management. My fault lies in my own lack of knowledge sometimes or my being scared to try to edit or sign something. Yet I can do so much more than I actually have to it amazes me. It is nice when I have to work on the go and don't have a lot of traditional options as i would use before-print, fill, sign,fax-etc. Stuff like that. I get great simplified organization here and it is right on point.I will keep growing and using this over time. It is the only way to play for me with needing to sign documents while on the go or out of my home area. Today with covid-19 shutdowns, I am at the mercy of technology more than ever.And I am not the tech type guy. I have to try, fail, try again and learn if all is well. Sometimes, I will get a document on my mobile that says sign and send back right away. I get confused on my Google options, other things I use and I have 2 phones and can easily get lost on both. PDF Filler works so easily and involves virtually nothing. I still get lost at times or can't get what I am aiming for on one of my personal devices. That is my error. The interface and expansions and lack for separate software actually are great here. Least liked features or issues are at my own fault here. It is pretty solid.
