Sell an item by weight or measure

Last updated 14 Oct 2026

Some things are not sold one at a time: cheese by the hundred grams, sweets by the
kilo, anything metered. An item can be set up so its price comes from a measured
quantity rather than from a count.

1. Turn it on

Open Shop → Product catalogs → Items Library, select the item, and go to its
Measure tab. Switch on Sold by measured quantity.

The Measure tab

2. Say what is measured and what it costs

  1. Measured quantity type: Weight (recorded in grams) or Volume (recorded
    in millilitres).
  2. Price per unit of measure: the rate as you price it, for example 89,00. Enter
    the number only.
  3. Price is per: the unit that rate is for, such as kg (kilogram), 100 g
    or l (litre). Use a weight unit for weighed items and a volume unit for
    metered ones.

A measured item needs this rate instead of a normal Price. Without it, saving
shows Enter a price per unit of measure for an item sold by measured quantity.

3. Set the optional limits

Setting What it does
Tare allowance Weight of the tub or bag (or its volume), taken off before pricing. Leave at 0 if not used
Minimum quantity Below this the sale is refused. Leave empty for no minimum
Maximum quantity Anything above this is treated as a misread. Leave empty for no maximum
Different rate by order type A different rate for eat-in or takeaway. Leave one empty to use the main rate

4. Save

Click Save. The till now prices the item from the measured quantity.

VAT looks wrong on it Measured items follow the same VAT rules as any other See Sell items at a different VAT rate
