Sell by weight

Price cheese, coffee beans or fish per pound or per 100 g, and weigh each one on the scale at checkout.

Set the item up

Open Products (or Menu in a restaurant). When you add an item, choose under Sold by: Pound, Ounce, Kilogram or Gram. The price you type is the price for one of that unit. For Gram, choose under Price per: 1 g or 100 g.

An item already on the list has the same choice on its row. An item sold by weight is never also an open price.

Weigh it at checkout

1. Tap the item. The Merchant Display reads the scale and shows the weight and the price as it settles.
2. Put the item on the scale. While it moves the weight says it is settling, and with nothing on it the screen says Place it on the scale.
3. When the weight has settled, tap Add. The scale is read again at the tap, and that weight is the one sold.

The line on the order, the receipt and the Customer Display reads like "Salmon 0.42 lb @ $18.00/lb". Each weighing is its own line. To refund one, refund the line; it comes back whole.

If the scale says it is over capacity, unplugged or not answering, those words are shown as the scale sent them. Fix that and the weight appears.

No scale at this counter

A weighed item is not sold without a scale, unless the owner turns on Allow typed weights under Setup, Permissions. Then the cashier types the weight off a legal-for-trade scale. In much of the US a weight sold to a customer must come from one.

The scale must speak NCI or Toledo 8217 over USB or serial, as most POS scales do, and be plugged into the Sparto POS.
