It was very helpful to have forms at my fingertips that required little effort to complete. It also provided some forms that I did not have but a customer required. Very helpful!

Aside from the cost associated with its use, I love PDFfiller! It is easier to use than the typewriter function in Adobe Acrobat and I could place text exactly where I needed it. One other recommendation is adding a spell check when finishing up the document. Respectfully, -RPS
