Sell access, time and experiences through one booking, membership and payment record.

Recreation businesses sell something that cannot be stocked. A tee time, a cinema seat, a pitch at a campground or a room for the weekend is gone once the slot passes. The booking calendar is the core record, because every empty gap in the diary is income that cannot be won back once the day has gone.

Membership sits beside it. A country club bills dues and house accounts, a golf course sells season passes and green fees, and a gym sells packages that are counted down by visit. Gyms, swimming pool companies and escape rooms also need entry checks, signed waivers and renewals, and each of them counts people through a door.

Some sell things as well as time. Boat dealers and RV dealers hold stock with serial numbers and trade-ins, and outdoor goods stores hold sizes and seasons across several shelves and racks. Travel agencies, tour operators and event companies build itineraries from many suppliers, each with its own rates, cut-off dates and payment terms to reconcile later. Radio stations schedule advertising against airtime, while casinos and cinemas count takings across many tills and shifts, and both must balance every night before the doors are locked.
