• ​In business markets, the total demand for goods and services is significantly affected by price changes, whereas in consumer markets, the total demand for goods and services is not significantly affected by price changes.

• ​In business markets, buyers usually purchase products through intermediaries, whereas in consumer markets, buyers usually purchase products directly from manufacturers.

• ​Purchasing decisions in business markets are made by the end user, whereas purchasing decisions in consumer markets are made by a buying committee.
