A discount column is available in both sales and purchase invoices. It is used to record the amount of discount that is given to the customer or supplier. The discount can be a percentage or a fixed amount.
In a sales invoice, the discount column is usually located on the line item that shows
the price of the goods or services that are being sold. The discount is calculated by multiplying the price of the goods or services by the discount percentage. For example, if the price of the goods or services is $100 and the discount percentage is 10%, then the discount amount would be $10.In a purchase invoice, the discount column is usually located on the line item that shows the price of the goods or services that are being purchased. The discount is calculated by multiplying the price of the goods or services by the discount percentage. For example, if the price of the goods or services is $100 and the discount percentage is 10%, then the discount amount would be $10.
The discount column is an important part of both sales and purchase invoices. It allows businesses to track the amount of discounts that they are giving to their customers and suppliers. This information can be used to make decisions about pricing and marketing strategies.
