What do you like best?
As a Realtor, my whole business is based on electronic documentation. PDF filler is kind of named poorly, because it really is a PDF editor. It allows you to easily change almost anything on a pdf document...across both desktop and mobile platforms. It simply works as you'd expect it to...every time. I use it practically every day.
What do you dislike?
I wish there were better tools for generating lines (how about a toggle into and out of orthagonal for a line?) It should allow deeper zooming with a thumbnail view showing where you are in the overall document. I like my pdfs to look perfect and sometimes these limit me in that goal.
What problems are you solving with the product? What benefits have you realized?
A Realtor literally lives or dies on his/her electronic documentation. This tool lets me master the changes that inevitably occur with documents. I use it every day.

What do you like best? It's ability to upload pretty much any type of document What do you dislike? I cannot really say anything I dislike about the product What problems are you solving with the product? What benefits have you realized? The biggest problem we have is that we receive uneditable documents that we are able to edit easily with PDFFiller. It's super beneficial because it saves us so much time.

Document Signing and Editing Issues I just spent about an hour or so with Kara, one of your most helpful and patient online chat professionals. I was in the process of completing a contract and addendums where my Buyer was pressing me. I sent it out to my Seller and the Buyer once and ran into a number of editing and fillable field issues. So I recalled it. Kara took me step by step through each issue and patiently explained everything to me via zoom and screen share. She even went a step further and pointed out some features to me that will help me in the future. Even though I was a bit stressed in trying to get my documents completed, she calmed me down with her knowledge level and patience.I sure hope if I ever need pdfFiller's live chat support again, I'm lucky enough to get Kara again or someone with the same level of expertise. I enjoyed chatting and working with her.Joyce

I really like the service a lot. It is user friendly and intuitive. I like that this also comes with Sign Now so that I can have all the forms I need for my business easy and accessible for me to get electronically signed. I would give it 5 starts except in the Sign Now program the program should default to the text box for people to sign and then have the live signature be on a separate tab, so basically reverse what it is now. It is hard for some people to get to the text box for them to type their signature. I use this all the time in my business and I would recommend it.
