Example

Complete procedure: the default live booking machine: party size, slot, resource, price, pay, persist, notify.

Goal: Mirror what most tenants already run — not every optional step.

Typical step order

1. PersonCountInput (or RequireInput custom counts + PersonCountFromParameters)
2. TimeFrameViaTimeLineCalendar (or calendar / on-date variants)
3. ManualSelectPlanElements or AutoSelectPlanElements (+ UseQuotas when needed)
4. PreReserveSelectedElements — hold the place while the guest pays (skip only if you accept collision risk)
5. AddPositionToOrder (quantities usually FromOtherParameter) and/or OrderFromMenu
6. RequireInput / DeliverAndBillingAddressInput for contact
7. PayNow
8. SyncReservationEntry → SyncOrderEntry → SyncInvoiceEntry — without these, Today / orders / invoices stay empty
9. InformGuestViaEmail → InformOperator (optional ReOrderMenu / TextBlocker)
