For example, IBM treats its business as a service business. Although it still manufactures computers, it sees the physical goods as a small part of the "business solutions" industry. They have found that the price elasticity of demand for "business solutions" is much less than for hardware. There has been a corresponding shift to a subscription pricing model. Rather than receiving a single payment for a piece of manufactured equipment, many manufacturers are now receiving a steady stream of revenue for ongoing contracts.
Full cost accounting and most accounting reform and monetary reform measures are usually thought to be impossible to achieve without a good model of the service economy.
