Selling goods from one business to another is known as _________ sales.

The correct answer is B2B, which stands for "business-to-business." This term describes transactions that occur between businesses, as opposed to transactions that involve direct sales to consumers or other setups. In a B2B sales model, a company sells its products or services directly to another company rather than to the end-user. This often involves larger quantities and potentially different pricing structures compared to business-to-consumer transactions.

Understanding B2B is crucial in contexts such as property management, where companies might sell services like maintenance, security, or lease agreements to other businesses. This contrasts with B2C (business-to-consumer), where businesses engage customers directly, and C2B (consumer-to-business) or C2C (consumer-to-consumer) models, which involve different dynamics, such as individuals selling to businesses or to one another, respectively. The B2B model emphasizes relationships, negotiation, and longer sales cycles, which are essential for understanding commercial transactions.
