# Sell by weight with a weighing scale

Sell loose goods — fruit, grains, cheese, sweets — by weight. The register reads
the weight from a scale (or you type it), prices the line, and can keep your
stock by weight.


CHOOSE THE ITEMS YOU SELL BY WEIGHT

 1. Go to More > Billing > Weighing scale.
 2. Under Items sold by weight, search for a product and add it.
 3. Pick its unit: per kg, g, lb, oz, l or ml. The product's price is the price
    per unit.
 4. Save.

This list is separate from the weight on the product page, which is used for
shipping.


CONNECT A SCALE

Use a scale that connects to the computer by USB or serial, with Chrome or Edge.
Under Weighing scale, set the Baud rate from your scale's manual and click Test
the scale.


SELL AN ITEM BY WEIGHT

 1. Add the item to the sale. A window asks for the weight.
 2. Put the goods on the scale and click Read scale, or type the Weight.
 3. Check the Line total and click Add to bill.

Each weighing becomes its own line on the bill.


SCAN BARCODES PRINTED BY A LABEL SCALE

Label-printing scales print a barcode that carries the weight or the price.

 1. Under Weighing scale, switch on Read label-scale barcodes.
 2. Set the Label barcode prefix your scale uses (usually 2).
 3. Under Label carries, choose Weight (grams) or Price.

The item code in the barcode must match the product's SKU, and the product must
be in your items-sold-by-weight list. These barcodes work with a USB barcode
scanner.


KEEP STOCK BY WEIGHT

Each item in the list shows how much is in stock, or stock not counted. Enter a
count and click Set to start counting. From then on, weighed sales take the
weight off stock, and returns and cancellations put it back. Setting counts
needs permission to edit settings.
