barter is especially good for service businesses as it is all but impossible to bill out all of your time, and time unbilled is income lost. Barter allows you to turn excess hours into money. Barter is a marketing, purchasing, and financing tool that offers you enormous profit opportunities. Your decisions should be driven by such present and future opportunities. Barter is often more inexpensive than monetary payment, because overhead costs normally associated with providing the services are usually avoided or reduced.
