👉 A promisor is a person who has an obligation to fulfill a promise or commitment. In the context of business, a promisor might be someone who has an agreement with another party to provide goods or services in exchange for payment. For example, if a company promises to deliver products within a certain time frame, it would be considered a promisor. Similarly, if a landlord promises to repair a property within a specified timeframe, it is also considered a promisor.
