So far I have found every form I have needed. The only problem I have is that I cannot print directly from the website. When I try to print I get blank pages.
Cindy H
I had trouble with printing but being the stubborn person I am, I did not request help. I did manage to print after a while. When I did complain, they listened and made a correction on the bill. I'm quite happy with the program now.
Ruth H
For my very first experience I was a little surprised it wasn't free when I already am an Adobe Pro in the Cloud user and pay monthly for that, but oh well.
Rosanne W
I had some initial problems (undoing things and a pop-up overtime I used text boxes). Customer support representative Ellie guided me through it and was able to resolve most of my problems. I still wish I could use the text boxes without the pop-up though. I believe at this time it is not possible.
Maritza M
The program very intelligently interprets PDF images, creating fields in just the right spot for us to type our responses in, while avoiding the print-write-scan-save cycle.
Busy Bee Q
It successfully sent a fax for me. I was able to upload forms that I needed from years past. So far, it has been exceptional. Will re-rate after a little more experience with it.
Sylvia
Easy Peasy We are an international company and approvals from everywhere around the globe are always needing signatures. Ease of use is key for fast turnaround on signing multiple documents. Can't think of anything to complain about.
Sue R.
I've been really happy with how easy it… I've been really happy with how easy it is to find certain forms, then fill them in and print them, but I wasn't able to find a few forms I needed and had to look for them elsewhere. I'd be ecstatic if all the forms I needed were all in one place.
Michele Hays-Morton
So far this has been exactly what I was looking for. We just upgraded from paper to a software system and I need something to make our contracts and enrollment documents fillable for the parents and students without redoing everything.
