Business services are those connected to banking, transport, warehousing, insurance, and communication that help businesses run smoothly. They have key characteristics of being intangible, inconsistent, having no inventory, and requiring customer involvement. Common types of business services include banking, insurance, and postal/telecom services. Banking services include deposit accounts, loans, drafts, ATMs, and e-banking. Insurance is a contract where the insurer agrees to compensate the insured for losses from uncertain events in exchange for premium payments.
