Great product for my home-based business. No more searching online for forms or templates and cutting/pasting the old fashioned way! Easy to use and all of the documents my business uses.

I've only used this service once, and I'm pleased with the outcome. My document looked more professional and I will use this service again. I think it's a bit pricey, so I suggest the company use a "one-time-purchase" option or free trial before buying.

needed to print out applications, employment verifications and a background questionaiire that required it be typed, printed out and sent via US mail. Most online PDF's will not supply editing capabilities. Thanks PDFillier!

It is easy to fill out proposals with your template. I wish there was a way to make it easier to access it because I will be using that document many times and so far I have had to search for it.

Great for what I needed it for
Needed to complete nursery registration forms for my daughters (which were emailed to me in PDF format), but have no access to a printer, so really appreciate software like this! Was quickly able to complete, and then email back to the nursery.If you are someone who regular needs to complete PDF's online, then you would really benefit from this.Was slightly confusing to begin with, but quickly got my head around it.

Really came through for me when I was charged a subscription fee. Being a small business owner, things get hectic. I had used it for my taxes and meant to cancel it but forgot. They cancelled my subscription and refunded the fee with no questions asked. Too bad it really wasn't a good fit for my business."
