What do you like best?

I love how we are able to reduce the time spent on onboarding paperwork in office by pre-sending the forms to be filled out at home. Also, it removes the need to scan and upload. It has greatly changed the way we hire (which is what we are constantly doing). We started using it middle of last year and the number of paper files we had at the end of the year compared to the year before was STAGGERING.
