I have an autistic son and this PDFfiller is so amazing. There is so much paperwork between social security, IHSS, ABA therapy services, and school this gives me a few extra moments to relax

I tried it before purchasing. The font, tick box selection and general feel is better, in my opinion, than that I have experienced with Adobe. My abilities are significantly challenged due to illness. The PDF document that I have to use presents with problems when I run it in other edit utilities. I may call on you if I get stuck, but so far I am favorably impressed with this product. Thanks. ;-)

prepare your base document, and save. then save as onto your computer desktop, and rename once downloaded onto your computer desktop. reuse the base document over and over for different clients.... works great and gave me the exact form i was looking for.

So far all worked really well, the only thing that could be still improved is to have the possibility to change the font size, when filling in a document

I am a learner, and have taken so much time to get the taxes into IRD so no time to spare. Used it to sign another form the other day, and I am getting to know the process, slowly.
