There is always one sales warehouse — the one the web shop and the till sell from. Add others (a central store, a container at the stadium) with New warehouse.
Receiving goods
Warehouses → Receive goods: warehouse, supplier invoice number (and the invoice file), products, quantities and purchase price without VAT. Each receipt is a document (RCV-2026-0001). Stock is valued first in, first out per warehouse.
Transfers and write-offs
Warehouses → Transfer moves stock (TRF document with a signable PDF); only what the source holds is offered. Damaged, lost or given-away pieces are written off with a reason (WOF).
Sales need no entry: a piece leaves the sales warehouse when it is put in a basket and comes back if the basket is abandoned or the sale stornated.
