pdfFiller scores top ratings on review platforms
This program worked for me when I had to do a state specific purchase & sale agreement/real estate. All six signers lived in different states and so had to digital sign. Easy to walk them through it.
I was needing a temporary custody order for my grandchildren. I found exactly what I needed on PDFfiller and it made for a great experience. I will be using this product as needed in the care and control of my Grandkids life.
There doesnt seem to be alot of "man in the street" logic to how you explain things. It seems to be written by Code cutters or IT people. Lots of simple things like , I look up how to save a document. You say : Save your document by clicking the 'Save as PDF' button in either the "MyForms" . There is NO such button only a "save as" button. Also Where is the "My Forms" page? is it named as such or .... ????Bascally though, its a great piece of software. You just have to get a REAL human being to rewrite instructions.

Using pdfFiller makes my life less hassle, I can easily put my signature in different papers as fast it can be, and immediately send via email to my boss. Since I have students, I need something that are very convenient and all topics in different PDF, I'll make it in one PDF so that my students will understand better and not using too many tabs, they can focus on one PDF only and make the student more convenient in studying. I can edit also anything I want in my PDF, I can easily put pictures, highlight the important words and removing text and pictures.
