It was a little frustrating for me figuring out how to use the program. This should improve with use and guidance. It would have been helpful if I had first down loaded the "How To Guide". Thanks for a great program.

Our agency management system has crashed this week. PDF filler is saving our business while we wait for it to be repaired. I have recommended it to everyone in our same situation

Great tool in a pinch! The google chrome extension worked really well since you can't just click on something in drive and easily open it - and I've had issues with Adobe for some time. This software did what I needed it to do multiple times. This is typically slow to open, and saving & retrieving files is a bit clunky.
