Very usable It was easy to get started and the options were not too hard to locate erasing is only left and right, the replace text field is not easy to use and it could be easier to just email a copy of a doc

A Great Time Saving Tool This software is a great time-saving tool in that it allows me to fill in, search, and edit forms and send them electronically within minutes. That way, I don't have to manually hand write information the form, then scan them (or mail them) and wait for recipients to respond. The software basically digitizes the workflow process, which saves me a lot of time. The software is limited to specific industries and the forms and features that these industries use. Therefore, not all forms and features are fully applicable to our company so we can't take advantage of them.

pdfFiller makes everything look more professional! Wonderful platform with tools that made our forms and electronic documents highly professional. Program allowed us to create fillable checklist for employees to use on jobs. The connectivity to other platforms really helped make it a snap to upload and rework forms for maximum efficiency. We don't use it enough to maintain a constant subscription--would like a month by month subscription that could be turned on/ off as needed.

THIS THING IS A DREAM (although I did have some kind of issue opening up a file.) I used the MERGE function and it merged some files I didn't need. That was weird. So I'm editing one page at a time instead. That seems to be working.

I had trouble logging in to my account I had trouble logging in to my account. It was a small issue but I sent a text message and got a reply soon after. The Customer Service at pdffiller is very responsive. I have been a customer (for creating insurance forms for my medical practice) for three years and it is an excellent service. It is user-friendly and intuitive and simple to use. I highly recommend pdffiller.
