In vertical analysis, the base for the cost of goods sold is sales
Sales are actions involving the sale of goods or the volume of items sold during a specified time frame. A sale also includes the provision of a service for a fee.
When a purchase, appropriation, requisition, or direct engagement with the customer occurs at the point of sale, the seller or provider of the goods or services completes a sale. Title (property or ownership) of the object is transferred, and a price is settled, meaning a price is agreed upon for which the ownership of the item will transfer.
