I didn't know it was going to cost money. I am just a private person trying to get Medicare reimbursement. The print is very tiny so proofreading is hard.

All i needed was the Rewrite PDF mode, All i needed was the Rewrite PDF mode,but you hide it took me almost 30 minutes to find this.And almost get out from this site..if you see i'm uploading a PDF file, suggest me the rewrite mode from within the Preview mode, (or on right click on the document - with the remove to trash and all the other options)

Makes work so much easier It makes my life so much easier As a credentialing manager I am constantly filling out paper work. This application makes it so much easier for me. Instead of downloading forms, filling them out and then re scanning to send forms, I just use PDFfiller. I don't really have a con for this application

What do you like best? PDF filler has allowed me to not only make forms being filled out easier but also allows me to keep them archived on their server so I had don't have to look for them. What do you dislike? I think the only downside I would say is the send to sign can be a little confusing. Some of my clients have had issues trying to sign things when I've used this feature. What problems is the product solving and how is that benefiting you? The only time I've had issues is when a form wouldn't load to the system. Customer service has always been great helping me out. They usually have the problem resolved quickly

PDF ****** provides a useful service that was difficult to find on other platforms. It does require providing payment info when you sign up for the free trial, but their customer service was extremely polite and helpful when I needed to cancel and get the charge refunded. **** helped me, and if I was in a position to need their service for my job or personal life, I would absolutely renew my subscription.

Good Features and Functionality I have used this software app for every type of editing, creating, and converting imaginable and have yet to have something it couldn't do. You can use the software for almost any kind of pdf editing, plus document type conversions. It is very easy to use without much training or help. The most recent update added a step to get to your full document list. Wish they would have left it at the original dashboard where all your docs appeared without the extra click.
