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.

I needed a platform that could merge documents together, edit them, sign them, then email or fax them. Ideally, all in one. I was introduced to pdfFiller last year. So I just went and got an account for myself, and have been using pdfFiller ever since.
