This essay sheds light on what are recurring revenue streams, demystifies the different types of recurring revenue streams, reveals the benefits of having recurring revenue streams, and delineates the challenges of building up recurring revenue streams that entrepreneurs can encounter. Recurring revenue streams are revenue streams that are expected to be able to generate revenue on an ongoing basis. The revenue generated from a recurring revenue stream is far more predictable than the revenue generated from a non-recurring revenue stream. A recurring revenue stream has the latent potential to provide revenue on an ongoing basis. It is preferable if a revenue stream has the latent potential to provide revenue in perpetuity and has an unlimited earning potential that is not tethered to your time. A companyÕs recurring revenue streams that generate substantial recurring revenue are able to do so as long as the target market is willing to pay recurring fees on an ongoing basis. Recurring revenue streams are for instance generated by companies that provide subscription services. In exchange for access to its subscription services, the companyÕs subscribers for instance pay a subscription fee on a periodical basis, such as a monthly basis, which thereby provides the company with recurring revenue. The more subscription services a company offers, the more recurring revenue streams that they can bring to fruition. Recurring revenue streams provide companies with revenue from ongoing payments on a periodical basis, such as a monthly basis. Subscribers are amenable to paying ongoing payments on a periodical basis, such as a monthly basis, to be able to avail themselves of continuous access to a service. Lamentably, even though revenue generate from a recurring revenue streams is not guaranteed, it is far more predictable than the revenue generated from a non-recurring revenue stream, especially since customers who provide companies with recurring revenue are content with making ongoing payments to have access to a service. Companies are also able to generate recurring revenue by providing access to products as a service which can provide their subscribers with access to products as long as they continue to pay a recurring subscription fee to access them. Recurring revenue streams can also be generated from investment securities. A company does not need to provide services nor access to products as a service to generate recurring revenue.
