Cash flow is the money that is moving (flowing) in and out of your business in a month. Although it does seem sometimes that cash flow only goes one way - out of the business - it does flow both ways.
Cash is coming in from customers or clients who are buying your products or services. If customers don't pay at the time of purchase, some of your cash flow is coming from collections of accounts receivable.
Cash is going out of your business in the form of payments for expenses, like rent or a mortgage, in monthly loan payments, and in payments for taxes and other accounts payable.
