Good for business
Works well most of the time with only about 5% of customers having difficulty signing documents. Plan to keep using
PDFFILLER does everything I need it to do for my business: quick edits, templates and storage.
Some workflow improvements could be made to save clicks and therefore time. Would like more flexibility to send templatized emails

Error in my ways!
I was unaware that I had used the service in the past which voided out my free trail. I then subscribed again and was instantly billed for a full year. When I realized my mistake, I reached out via instant message to the support staff. The service was stellar at best. They assisted me promptly and corrected my dispute which was impressive to say the least and speaks to the integrity of this service.

We were out of town and needed an expensive package delivered to an alternate address. We needed a signed release for the courier to deliver without a signature, and this was the best way to create and eventually email that release form.

I needed a straightforward way to file an extra tax form, and PDF Filler helped me out! Much easier than finding the form on the IRS website (somehow impossible?) and hoping for the best.

What do you like best?
Easy to replace text, add images, send for signatures, etc.
What do you dislike?
The organization of "my documents" is not very intuitive. Also wish there was an option to open the document without downloading.
What problems are you solving with the product? What benefits have you realized?
I have been able to complete team documents with multiple signers who are all in remote locations. I am able to rearrange and create valuable reports each month.
