Administrator in Education Management

What do you like best?

I am able to process forms efficiently and on the go. In the past, I would have to wait until I receive something in my mailbox to be submitted, but not anymore. Also, I don't get buried in paper or have to wonder if I missed a form somewhere.

I really enjoy the ability to easily share and sign contracts. I appreciative that these count as legally-binding contracts. Additionally, I really appreciate how transparent the entire process is (with countersigned contracts emailed to everyone).
