lineSubTotal

lineSubTotal refers to the calculated sum of the price of an individual item multiplied by its quantity within an order or invoice. This value represents the total cost for a specific line item before any applicable discounts, taxes, or shipping charges are applied. It is a fundamental component in the breakdown of an order's total cost. For example, if a customer orders 3 shirts at $15 each, the lineSubTotal for that shirt line item would be $45. This calculation is typically performed for each distinct item or group of items on an order. The aggregation of all lineSubTotal values then forms a subtotal for the entire order, upon which further calculations are based. This ensures clarity in itemized billing and provides a basis for understanding the cost contribution of each product or service.
