Performance is slow and choppy at times. There is no OBVIOUS way to turn off the popups every single time I go to fill out a form. Transitioning from one form to another is extremely disjointed. There is no clear way to fill out one form and simply move on to the next in a series. If there is a clean workflow in there somewhere, it's not obvious, at least, not for my use case, which is to fill out a form for each of my employees from a remote location, download all and print all for distribution. Seems like every time I finish something, it takes a while to save, and a while to get to the page letting me choose what to do next, which is always to display the file list again, and a while to load the file list. . .rather than simply keeping the filelist persistent and hidden, as would seem same here. Also, this form, won't let me enter more than a character or 2 before kicking me out. I am writing this feedback in a notepad and then copying it in all at once. Awesome.

Its good, except that it saves the document automatically without allowing a Save as function when printing, so it overwrites the previous file, which is not so good.

PDF Filler is a must for me!
I love it! As a small business owner who strives to maintain a professional business image (website, business cards, etc.) , PDFfiller does just that for the proposals I create for my customers ... both future, and repeat. I know for a fact my customers appreciate the quality and professionalism of the proposals they receive from me - they've told me so! Thanks PDFfiller!
I love the ability to quickly, and easily, create/copy professional proposals for my customers. I then save each file as a PDF (with my logo embedded at the top left of each document), and attach via e-mail for completing my estimation process with each customer.
The only thing I've discovered is with the particular template I use for my particular proposals - my template has an area that indicates "Page 1 of _" ... well, there are no additional pages that are affiliated with my template, so I end up either having to re-edit to ensure my entire proposal fits into "Page 1", or I have to continue additional pages outside of PDFfiller.

All trials have been very satisfactory. It has been easy to learn the use of the various features. Especially the relatively small size of the ready documents is appreciated.

How often does one get 5 star support?
How often does one get 5 star support?
Unfortunately the answer is not often at all.
But today was different.
I got 5 Star Customer Support from Kara on Team PDFFiller.
More importantly Kara was patient and guided me to work through the problem with my login issue.
Success all the way around.
Happy customer is a loyal customer.
Thank you Kara.

What do you like best?
It is much easier to use than Adobe Acrobat. Much more intuitive functions and file management. It has saved me a ton of time with the cloud storage of documents. I have used effectively for construction related documents.
What do you dislike?
Very rarely I have needed to use another platform because some municipalities require it but 98% of what I need to do is supported.
What problems are you solving with the product? What benefits have you realized?
Remote completion of forms and extracting text from PDF documents mostly.

I only needed it for one purpose, to make my client's insurance claim sheets a fillable form so I wouldn't have to freehand it. After the initial struggle to get it structured right it works wonderfully
