All Payout Report for Bookkeepers

What triggers a “Pay in person” payment method to show up on the All Payouts report?

I am working with a client that uses Wix for bookings, deposits, and payment processing. My question is, when an item is on the All payout report as “pay in person,” does it mean the appointment has been fulfilled and it is assumed the payment was received? OR does I mean an appointment was booked and the deposit is due?
