Currently, eHopper POS does not support scale or weight devices. Look out for this feature soon!
For now, as a workaround, you can set prices for inventory items per weight unit, such as by ounce, gallon, pound, gram, and kilogram.
1. Go to Inventory--->Products--->New Item button--->Pricing tab in Back Office.
2. After selecting either a Fixed or Manual Price Type, select a weight unit from the Unit drop-down.
3. Input the Sales Price you would like for each weight unit sold of the item.
