G'day @kimapollo, no-shows on a big night are the worst, we feel your pain!
As far as I know there's no "deposit on these dates only" switch, but a couple of workarounds:
If you take bookings through Square Appointments, set up a separate "NYE Booking" service with its own prepayment/deposit and cancellation policy, and only make it available on the 31st. Your normal bookings stay deposit-free.
Or treat it like an event ticket: sell a "NYE Table Deposit" item through Square Online, then take it off the bill on the night. Bonus is the money's in the bank before the night, not after.
Either way, put the deposit and refund policy right in the item description so there's no argy-bargy on the night. Good luck with it, haha, and happy new year in advance!
