I wanted to get the discount and pay for the whole year, not sure, it wasn't clear weather I actually paid that way or am paying for a month at a time? Need to make that easier to understand and make sure you are paying the way you want for the discount. You can do a follow up survey only if you are on the line when you call -
It is sometimes difficult to understand how to use the different functionalities. Your "how to" guides focus on "push this button, then this" but are not focused on the end product (i.e. " how do you create a XXXX")
I had been looking for something which works on phones & chromebooks as well as computers. It's great this operates 100% in a browser and works REALLY well. Has some limited zapier support and has decent integration with g-suite. The support, including one emergency thing, has been much better than average. There are some additions which I feel could make pdffiller absolutely a star, but it's more than functional and easy to use today.
What do you like best?
The best feature of PDFFiller is its ease of use, whether it's editing documents, signing documents, and then being able to access your documents anywhere by logging onto the site, as opposed to being constrained if you don't have your computer files with you.
What do you dislike?
Some of the option menus should be improved upon, especially as far as layout and ease of finding what you need, it's a bit counterintuitive though with experience that becomes less of an issue.
What problems are you solving with the product? What benefits have you realized?
Signing PDFs with ease. Being able to access and edit a pdf no matter where I am as long as I have internet access, even if I don't have my computer with me and/or don't have access to my cloud storage.

It's easy to work with. Wish there was a "clear all" button so that I wouldn't have to close and open back up to start a new form, but overall, great product
Outstanding customer service, communication and efficiency!! I highly recommend. They are one of the best, if the THE best company I've ever dealt with!
What do you like best?
The ease of use, the verification of signature and the compatibility on all types of documents
What do you dislike?
The cost...yearly is pricey considering there are programs that you pay more upfront but it’s a one time fee
