I have difficulties to send to sign to 2 people at the same time. I follow instructions but it does not work. The rest is good, specially on line help is good! Thank you

PDFfiller is very easy to use and the auto-save feature works reliably. One thing that I didn't like was that I had to sign up for a plan to be able to save my pdf. Had I not chosen to sign up, I believe my work would have not been saved. What compelled me to sign up was that I didn't want to lose the work that I was doing. Overall, I think PDFfiller is a great tool and worth the money; however, some users may not like the mandatory payment in order to see their documents again.

It is difficult to find the exact years… It is difficult to find the exact years form. For instance, I searched for 2019 1040 SE and I got a lot of 2014 forms. I had to over search for the correct form.

This site was exactly what we needed to edit pdf's and create fillable fields for all of our school enrollment forms. The options for receiving the information when completed, as well as many other perks made this a perfect product for our use. We continue to find more and more uses in our school setting for using pdffiller. I highly recommend this product.
