UOM Conversion

Items can have multiple UOMs with conversion factors:

  1. In the Item master, set the Default UOM.
  2. Add conversion factors in the UOM Conversion table:

- UOM: Alternative unit (e.g., "Box")

- Conversion Factor: How many default units equal one alternative unit (e.g., 1 Box = 12 Pcs)

Example: If Default UOM is Pcs and 1 Box = 12 Pcs:

  • Selling by Box: Enter quantity 1 in UOM "Box" → system converts to 12 Pcs for stock
  • Purchasing by Box: Enter quantity 1 in UOM "Box" → system receives 12 Pcs

Using Different UOMs

Transactions support selling/purchasing in different UOMs:

  • Sales Order: Sell in "Box" at a box price
  • Purchase Order: Buy in "Kilogram" at per-kg price
  • Stock is always tracked in the default UOM
