I am a self represented defendant in a small claims case. I cannot afford an attorney. With the robust capabilities, and plenty of time on my hands, I can plow through the case law and ca civil codes, but I can't readily find and fill out forms. PDFfiller has the forms I need and does a credible job of filling them out.

What do you like best?
The ability to edit PDF documents quickly and easily
What do you dislike?
When documents are locked by other applications such as DocuSign you cannot sign them or open them with this software. You are however able to sign them on that platform after creating a separate logon with DocuSign.
What problems are you solving with the product? What benefits have you realized?
Ability to send to sign is a huge time saver in getting contracts signed by sellers

Glad to have it Glad to have it. Wished i didn't have to reset with every entry. It should assume you want the same font until you tell the program to change. Gets tedious to change for every number on the page.

It's kind of quirky, because I[m not familiar with pdfFiller and it just pops up all of a sudden out of nowhere, so I don't know where to begin.
