Collect payment for billable order positions already present in procedure state.
Prerequisites (implicit): Positions from Aggiungi posizione (AddPositionToOrder), Ordina da menu (OrderFromMenu), Aggiungi posizione notti (AddNightsToOrder), or stashed reorder positions. Completes immediately when the gross total is zero.
Configuration highlights: Payment provider, invoice template, optional fiscalization, allow-waiting-payment.
Typical place in the funnel: After pricing (and usually contact/address); almost always followed by sync + notify.
Downstream (very stable in live data): Crea una prenotazione (SyncReservationEntry) and/or Crea un ordine (SyncOrderEntry) → Creare una fattura (SyncInvoiceEntry) → Informa gli ospiti via e-mail (InformGuestViaEmail) → Informare gli operatori (InformOperator), sometimes Menu di riordino (ReOrderMenu) or a closing Procedura di blocco (TextBlocker).
