A gaming club bills time, not items, and the money walks in and out all evening. ClubManager keeps a live picture of which tables are running, what each one owes, and whether the cash at the end of the shift matches what the system expected.
Drinks and snacks attach to the running session rather than becoming a separate ticket, so a table settles once. Members can hold a wallet balance, and credit can be extended and settled deliberately rather than remembered.
Your venue gets a public page where customers reserve a table without creating an account. They arrive with a booking pass on their phone and can check themselves in; the front desk sees it land with the booking already attached.
Ending a shift reconciles cash collected against what was expected, and a large variance can require a second person to approve it. Voids, refunds and discounts can be put behind the same gate — which is the point at which a club stops losing money it cannot account for.
