The tasks I needed to complete I was able to facilitate with PDFiller. I was later informed of a more economical manner. I manage a non-profit org. We always need to be conscious of cost.

Had an issue with billing today (a… Had an issue with billing today (a Saturday) however after emailing their customer service team I got a very quick response and kept getting help and support until the issue was resolved, on the same day. The person I was in contact with was very polite, understanding and genuinely wanted to help. The service itself is great and I would recommend it to any business that needs to edit and sign documents online .

A good all rounder for filling pdfs and signing forms pdfFiller is a useful tool that lets me fill, sign and send client contracts I like being able to add text to pdf forms, then email,download or print the completed forms I have to be honest, it's a bit clunky and takes some getting used to

What do you like best? Easy to replace text, add images, send for signatures, etc. What do you dislike? The organization of "my documents" is not very intuitive. Also wish there was an option to open the document without downloading. What problems are you solving with the product? What benefits have you realized? I have been able to complete team documents with multiple signers who are all in remote locations. I am able to rearrange and create valuable reports each month.
