I did a lot of shopping , signed up with a few other apps, once I tried this one,I went back to all the ones I was on a free trial with and cancelled . This was the one. It was easy and I was able to use it the way I wanted immediately and have been using it almost every day.

What do you like best?
I personally like using PdfFiller over other programs like Adobe to edit my documents because the site is more user friendly. I can do everything I need to quickly and efficiently.
What do you dislike?
I wish there was an option to combine documents. You can delete pages but not upload new ones.
What problems are you solving with the product? What benefits have you realized?
I used to use Docusign to add digital signatures but now I used pdfFiller instead. It's great for adding quick signatures on internal documents without the waste of printing and hand signing forms as I did prior.
