Collect payment for billable order positions already present in procedure state.
Prerequisites (implicit): Positions from Agregar posición (AddPositionToOrder), Ordenar del menú (OrderFromMenu), Agregar posición de noches (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): Crear una reserva (SyncReservationEntry) and/or Crear un pedido (SyncOrderEntry) → Crear una factura (SyncInvoiceEntry) → Informar a los huéspedes por correo electrónico (InformGuestViaEmail) → Informar a los operadores (InformOperator), sometimes Menú de reordenamiento (ReOrderMenu) or a closing Procedimiento de bloqueo (TextBlocker).
