Shipping, inventory and suppliers
Shipping methods and zones, stock across locations, and the suppliers you buy from.
Shipping
/shipping — the methods you offer (flat rate, by weight, by order value, free over a threshold, collection) and /shipping-zones — which countries and regions each method serves at what price. Checkout offers the methods whose zone matches the address.
Inventory
/inventory — stock per product and variant. Stock is reserved when an order is paid and released if it is cancelled. Set a low-stock threshold to be notified. Locations (/inventory-locations) hold stock in more than one place — a warehouse, a shop — and an order is fulfilled from the location you choose.
Suppliers
/suppliers — who supplies each product, their contact details, lead time and cost, so reordering and margins are visible from the product.
