The transaction is typically documented through a receipt or invoice, ensuring both parties have a record of the agreement. The process of Transaction A includes several steps: negotiation of terms, agreement on price, and the actual exchange. Once both parties fulfill their obligations, the transaction is considered complete. This type of exchange is fundamental to commerce and can occur in various settings, such as retail stores or online platforms.
