Price Items by Weight
Currently you’re unable to fully integrate scales with the Square app to price items by weight.
In the meantime, the following options allow you to price items by weight:
Use a third-party scale and the Square app’s variable pricing feature to process these types of transactions.
E.g. Pre-program the weights of your items in the scale and enter those prices during the time of sale using a variable priced item.
Use individual items as a specific measure of weight.
E.g. Set a price of X for an item called “Tenth of Pounds”. If an item is 3.2 pounds, enter a quantity of 32.
