Units, codes and selling by weight

Describe the pack size, identify the product with a barcode, and let customers buy loose quantities such as 0.75 kg.

Shop owner, Shop Product Manager

The Unit & codes card is on every simple product. A product with variants sets the unit and codes on each variant. Its Details tab has a Selling by measure card instead and, when the HS / HSN code applies, a Codes card.

Unit

Field	What to enter
1. Unit	Choose from the list, for example Kilogram, Gram, Litre, Millilitre, Piece, Packet or Dozen
Unit value	The amount in one pack, for example 500
Unit label	The text customers see beside the price, for example "500 g"

Sold loose by weight/measure

The Sold loose by weight/measure switch, not the unit, decides how customers order the product.

Off is the default, also for every product that existed before the switch was added. The product sells in whole units, whatever its unit: a 1 kg bag or a 1 L bottle is one item.
On lets customers choose how much they want, for example 0.75 kg of tomatoes. Two fields appear:

Field	What it does
Step	Customers choose a quantity in steps of this amount, in the product's unit. Blank means 1
Minimum	The smallest quantity a customer can order. Blank means the same as the step

Both must be greater than 0, with at most two decimals. The minimum cannot be less than the step and must be a multiple of it: with a step of 0.5, use 0.5, 1 or 1.5.

The switch needs a weight, volume or length unit. With any other unit the page answers: "Sold loose by weight/measure needs a weight, volume or length unit (kg, g, L, ml, m …). Pick one, or leave it off for a count item."

Products with variants

The Selling by measure card has the same switch, Step and Minimum. Saving copies them to all the product's variants. It is refused unless every variant that has a unit uses a weight, volume or length unit, and at least one variant has one. On a new variable product, generate the variants and set their units first.

Codes

Field	What it is for
3. Barcode	The code on the pack. A picture of the barcode is drawn under the fields as you type
External product ID	The product's code in another system. Imports can match products by it
Batch ID	A reference for the batch
HS / HSN code	The customs or tax classification code, for example 6109.10. Shown when tax is on, when your shop delivers By Shipping Zones, or when the product already has a code
