The cash flows from operating activities section of the cash flow statement is probably the easiest for you to understand and relate to. This section reports the actual cash inflows and outflows of your company from your operations (cash flows from the accounts that are included on your income statement).
These accounts include sales revenue collected and expenses actually paid such as payroll, materials, supplies, taxes, and insurance. This section does not include accounts receivable (sales that customers haven’t paid for yet) or accounts payable (invoices you haven’t paid yet), because these transactions don’t affect the cash position of your business.
The most important thing you can learn from the cash flows from operating activities section of the cash flow statement is whether or not your company is generating enough cash from operations to pay the bills.
As I wrote in an earlier post, “Happiness is a Positive Cash Flow”. You can gauge your company’s happiness from the operating section of the cash flow statement.
