The term "additional revenue stream" refers to an additional source of income that a company can generate through its products or services. This means finding new ways to monetize existing offerings, expanding into new markets, or introducing new products and services that can bring in more money for the business. Having multiple revenue streams helps companies become less dependent on one particular product line or market, making them more resilient during economic downturns or changes in consumer demand. In summary, "additional revenue stream" is a phrase used to describe any effort by a company to increase its income through new sources of business.
