Sales—or sales revenue—equals the dollar amount a company makes during the period under review.
Sales volume equals the number of units a business sells during a given period, such as a year or fiscal quarter.
The concepts of sales and sales volume interconnect because total sales equal sales volume multiplied by the unit price.
For example, if a company sold 1 million units of a product at $2 apiece, the corporate sales volume would be 1 million, yielding periodic sales of $2 million (1 million multiplied by $2).
