pdfFiller scores top ratings on review platforms

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.

Recently tried to use a function that wasn't available to me which I thought the personal plan I had subscribed to gave to me. I had a chance to do the shoppers review survey and because of this gave them three stars. I was surprised to get an email from PDF filler offering me an upgrade to my subscription so that I could get all the features that I want free for a year. It certainly resolved my issue and I was glad to upgrade my previous rating of PDF filler to 5 stars! Great customer service!

Taking a while to learn how to do this, but it is great. Questions: (1) Tell me how to transmit this electronically to you. (2) May I use the same form to register different Scripture we publish? Most elements in this first registration will apply to all that we register. (3) How do we handle the fee for registrations, and what do you need in addition to this and a fee? (4) I have a hearing problem, and need to be in e-mail contact with you (life3@gmx.com). Leon Taylor, Chairman of Vietnamese Bible, Inc.

A feature that is critical to my business broke on Friday. I was able to interface and get updates about the fix over the entire weekend and had the problem solved by the dev team before Monday morning. Awesome teamwork from the folks at PDFiller from end to end. Highly recommend.

The reason it is a four instead of a five... The reason it is a four instead of a five is I feel like there is a strong learning curve... at least for me. So I am still learning. Check back with me in a month and let's see if we can delete this 4 rating and move it up to a 5!!

If you have forms to fill out electronically, this is the website to use. It is simple even for those not great with tech! Customer service is also very honest and helpful as far as billing, etc.
