Enterprise value-to-sales (EV/sales) measures how much it would cost to purchase a company's value in terms of its sales. A lower EV/sales multiple indicates that a company is a more attractive investment as it may be relatively undervalued. Essentially, it uses enterprise value and not market capitalization like the P/S ratio. Enterprise value adds debt and preferred shares to the market cap and subtracts cash. Since it does account for a company's debt load, the EV/Sales ratio is said to be superior, although it involves more steps and isn’t always as readily available.
