Cash flow is a term within business and accounting that refers to the inflow or outflow of money for a specific period. For example, if a company uses the subscription pricing model with monthly payments, the money flow that comes in each month will be the combined subscription fee that customers pay. If the company buys a product, that money outflow will decrease the total flow of money for that month. This is because a purchase is a cash outflow. In this example, that cash inflow is also called the Monthly Recurring Revenue (MRR).
