Loved this, actively trying to get more offices in our company to use it

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.

What do you like best?

I use it to append my signature on documents requiring my signature without needing to print it first then scanning it into a new document. Time can now be used for other important things. I also like how I can send or invite other people to sign documents.
