A sales contract (SPA) is a legally binding contract between two parties that has entered into a transaction between a buyer and a seller. SPAs are typically used for real estate transactions, but are found in all industries. The agreement concludes the terms of the sale and is the culmination of negotiations between the buyer and seller. In another example, a SPA is often required in a transaction in which one company acquires another. Since the SPA determines the exact nature of what is being bought and sold, the agreement may allow a company to sell its physical assets to a buyer without selling the naming rights associated with the transaction.
