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.

Using the app has been pretty easy so far Using the app has been pretty straight forward and intuitive. Getting used to how to edit a PDF to get consistent results. Has been a big help. Users always want a free solution and I'm still testing the 30 day trial but maybe if you want the right solution it needs to be a paid solution.
