It was really easy to fill out the forms and print them. Normally, I wouldn't spend money for this type of service, as I can just print the PDF document from the internet. This time, however, I just didn't want to have to write all the information. Also, if I wanted to make changes, I loved that I could change any field and not have to write over it (as I would have otherwise).

Excellent customer service/IT I had occasion to need assistance in performing a certain process within this program suite. The IT person with whom I was connected (Joyce) was courteous and professional. She determined the solution to my problem taught me what I needed to know in a matter of minutes. I had made two previous attempts to resolve this earlier in the day, but once I was online with Joyce it was resolved quickly and easily. She is a gem.

I think it would be worthwhile for anyone who works with documents to learn how to use this app but I just don't have the time and only needed one document. When it came time to cancel, they were gracious enough to make it easy by clicking on cancel instead of having to call or write and jump through hoops. Thank you pdfFiller for letting me try your app.
