There might come a time in your business's life when you want to barter your services. In fact, you may find it prudent from time to time to trade your services for the services that another business offers. It helps to have a plan in place for this and to have some safeguards against overextending your services beyond what you can support. After all, if you barter all of your services all of the time, then you'll never earn an income.
Economic historian Karl Polanyi has argued that where barter is widespread, and cash supplies limited, barter is aided by the use of credit, brokerage, and money as a unit of account (i.e. used to price items). All of these strategies are found in ancient economies including Ptolemaic Egypt. They are also the basis for more recent barter exchange systems.
