I use PDFFiller for our trucking company Bills of Lading and Log Sheets. I absolutely love it! My paperwork looks so much more professional and the more I use it the more I like it.

I sat down and began using it right away without any tutorial what so ever. It's just that easy. Looking forward to learning what else this program can do.

An easy method of filling out and sending documents. Problem with sending document due to 'Bugs' in the system
It took three tries to send off a document and I still do not have a confirmation that it was send nor d I have a date in which the document would be received.
The concept is good as I can go to the website and complete a document and send it off. Still some bugs

I love it! my only gripe is not being able to send emails with pdf's as normal attachments. I have to send a lot of PDF's to insurance companies and they complain that their systems cannot open the PDF's as sent from pdffiller so I have to take the time to download them from pdffiller, upload them to my CRM, and then attach them in emails. It would be great to be able to save that time. But other than that I am very impressed with the service.

What do you like best?
Ease of use, variety of tools, and it has everything I need for my line of work which is Real Estate.
What do you dislike?
Font choice is a little limited unless I don't know how to find them... Other than that, I've used PDF Filler for about three years now and it is almost a necessity with my job.
What problems are you solving with the product? What benefits have you realized?
I've used it numerous times in Real Estate transactions to finalize contracts, revise items, and change information, etc. It makes my job much easier, neater, and smoother.

Quick to respond and follow through
I had an issue and emailed the company and not only did 2 different people respond immediately they resolved my issue within a few hours of me sending the email. I’ve never seen that quick of a response before. Very impressive.
