Answer:
Business to business (B2B) transactions
Step-by-step explanation:
B2B transactions refer to basically selling goods or services to other companies that need those goods or services in order for them to produce or distribute their goods to their final customers. A B2B transaction that not include final customers, it only includes businesses.
Many times companies have different product lines depending on their users, e.g. Kimberly Clark sells Scott paper products to final customers, but it also sells the same products but packaged differently to B2B customers. Their division is called Kimberly Clark Professional and they sell paper products for dispensers, the ones that you find at restaurants, airports, movie theaters and almost everywhere. They are basically the same products but since they are used by many people, they have to be adjusted for health and safety issues.
Another example would be fleet car sales, where large rental companies purchase fleets of cars at a discount price. Those cars all come in the same trim and sometimes even the same color.
