Unfortunately I paid for PDFescape before I found you. I subscribed to the Ultimate - it was very user unfriendly with absolutely no online tutorials or help - and I am no novice, I have designed and published several of my own websites. I really think yours is great and have had real a good experience working with setting up my contracts with it. Thanks! Sam

We have had a service application on line for several years. People have been printing, handwriting the answers to our application and emailing it back. I just received back my first fillable application and I love it. It is legible and all the answers appear where they are supposed to no more writing up the side of the page because of the limited space for answering.

Fumbling along with Adobe Acrobat or hand-writing forms was time-consuming, sloppy, and completely inefficient—especially if changes or updates were needed. We are going to continue to use pdfFiller and find additional uses for the product as our business grows.

pdfFiller saves us $100 or more each workday when you factor in employee time and supplies. The figure is probably higher than that, since the waiting time for patients not yet seen is also diminished, which keeps the patient from being frustrated and just leaving before their visit.
