-  - Orders (Bestellungen) live at `/auftrag/bestellung` and `/auftrag/bestellung/:orderId`.
+  - Quotes (Angebote) live at `/auftrag/angebot` and `/auftrag/:quoteId` (or `/auftrag/angebot/:quoteId`).

   - Payments (Zahlungen) live at `/auftrag/zahlungen` (payment bookings and payment balances).
 - Both IDs (`quoteId`, `orderId`) are document IDs.
