I really liked the entire PDF Filler platform! The content was laid out clearly and it was really easy to get started (even when I was frazzled about other things). Working with the platform in seamless and I have already recommended it to my mom who uses PDFs in her company 24/7

IT'S BETTER THAN DOCUSIGN I like that you can send to other to sign just like docusign. You can also fill in the blanks. You can share the info and even print. Also is not too pricey. What I don't like is, when I send to multiple signers anyone can sign even on my signature. I wish they'd allow set signatures per person so that folks won't get confused .
