Very user friendly. I had to contact support and they assisted me very quickly and sent me the correct form to use for an insurance claim I was working on. Looking forward to using this service again. 6/13/16 Makes my life a WHOLE lot easier!

originally i was dissatisfied with paying $20 to learn how to use the system and still did not get any benefit. Then customer service reached out to me to provide assistance and work on a solution. I am still learning how to effectively use it but am happy for their willingness to help.

I like the program. I did pay for it, so I feel that I should be able to upload pictures to the file. Uploading images should be included in a basic membership. I still like the service.

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.
