A Unit of Measure (UOM) defines how a product’s quantity is counted — Kilogram, Piece, Box, Litre, and so on. Every stock-tracked product needs a UOM assigned on its Stock Profile, and every line on a Purchase Order, Goods Receipt, or Invoice records its quantity in a UOM. Get your core units set up once, before you start tracking stock.

UOM Fields

Keep your UOM list short and reusable — most businesses only need 3-5 (e.g. Piece, Kilogram, Box, Litre). You don’t need a separate UOM per product.
