Great Product for My DJ's and Clients

Darren G

What do you like best?

I love the ease of use to set up templates and the ability for my DJs to sign their payment receipts on their devices. I also love that I get alerts and reminders automatically when clients haven’t signed their agreement. I also like how you can assign multiple signers and store a signature to make the process of creation faster.

What do you like best?

Made our onboarding so much easier. New hires are able to send information and get in faster! It is so much easier to be able to send this to a new hire. Now we are able to send this to them and we can see who is coming in before and prepare for our day. Spend your time on training instead of filling W2 all day. Also cleared up so much room in our filing cabinets.
