What our customers say about pdfFiller
See for yourself by reading reviews on the most popular resources:
Just started. Quite happy so far. Still a little confused. When I am bringing up the same patient from last week when we just signed up, kind of confusing for us. It is okay now when we see the small icon to print from, because we only have two patients, but it is a trial and error because you can't really read the patient's name until the last phase of the print screen. This will be an impossible task once we get 10-20 patients. We need to learn more about it. Also, do you have a clearinghouse feature so that we can just submit the claim electronically?

I like it but I still don't get the refined product I am using plus in the ad, it said "$6/month" when they charged me it was $20. How come?

Sam, on-line support did a great job!
I was very happy that Sam at the On-line Support, came on very quickly and helped me with what I needed and waited until I was sure it worked. I was also very happy that the program did "not" shrink the size of the words in the document like many other programs I have tried.

This product is very easy to use and I am impressed with the various toll available to make the changes to the PDF files.The service and backup provided by the support team is excellent. I cannot fault their response times (within 20 minutes of my email) and they were attentive to my concerns and resolved the invoice issues immediately. Totally would recommend this to anyone.
