Marketplace inventory is at /marketplace/seller/inventory and retail inventory under /retail/inventory. The active business determines the inventory shown.
Inventory supports SKU, barcode, cost, selling price, stock, reserved stock, available stock, low-stock threshold and variants. Movements include sale, marketplace order, restock, correction, damaged, return, reservation, release and refund. Use a reason for manual adjustments. Marketplace and POS share stock and use transactional reservations to prevent overselling.
