Hard to find the erase button. But after I asked, I found it buried in the "tools" --seems like it should be more visible. Love the tool's simplicity otherwise.
Thom D
I had an initial difficult time getting use to the program. I have now fine tuned the functions and have accessed the benefits. The support online was informative and patient with my frustrations. I will recommend this program to my clients and co-workers. The cost is reasonable.
Jacquelyn
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?

An Alternative To Adobe Run a small business without additional Adobe and DocuSign subscriptions.... It is a great value and it surprises me with new features on a quarterly basis. When I need new functionality I search for it and am no longer surprised when it is there! I wish it would break down .PDF text into MS Word documents.

What do you like best? How easy it is to access all documents and edit previous documents What do you dislike? I wish there were more tools to help edit, such as cropping a document or resizing What problems are you solving with the product? What benefits have you realized? It usually takes a while or is difficult to edit a document, but with PdfFiller, it's easier and faster. I can take a form I often use, and instead of entering the information every time, I can change the date

It's user friendly and I'm figuring it out as I go... just a bit of support with downloading to my google drive and figuring out why/when to use the link would be great.
