A sales transaction occurs when a buyer exchanges money for goods or services from a seller. This process typically involves an agreement on the price and the terms of the sale, which can include payment methods and delivery options. Sales transactions can happen in various settings, such as retail stores, online platforms, or through direct sales. During a sales transaction, both parties must fulfill their obligations. The buyer is responsible for providing payment, while the seller must deliver the agreed-upon product or service. Proper documentation, such as receipts or invoices, is often generated to record the transaction for future reference.
