Cash flow statement explained for small business owners

Your profit and loss statement says you made money last quarter, yet the bank balance barely moved. That gap is exactly what a cash flow statement is for. With the cash flow statement explained in plain terms, you can see where cash came from, where it went, and why profit and cash so often tell different stories. This guide walks through the three sections, explains the indirect method with a small example that adds up line by line, and shows what to look for when you read it each month.

What a cash flow statement shows

A business normally produces three core financial statements. The profit and loss statement (income statement) shows revenue and expenses for a period. The balance sheet shows what the business owns and owes on a given date. The cash flow statement, formally the statement of cash flows, connects them by showing how the cash balance changed between two balance sheet dates.

Every cash movement is placed in one of three groups:

Operating activities: cash from running the business day to day. Money collected from customers, and money paid to suppliers, employees, landlords and tax authorities. Under US GAAP, interest paid and income taxes paid also belong here.
Investing activities: cash spent on, or received from, long-term assets. Buying equipment, vehicles or software you capitalize, and the proceeds when you sell them.
Financing activities: cash from or returned to the people who fund the business. New loans, loan principal repaid, owner contributions, and owner draws or dividends.

The three totals add up to the net change in cash for the period. Add that change to the opening cash balance and you get the closing cash balance, which should match the cash accounts on your balance sheet.

Why profit is not the same as cash

Most businesses keep their books on the accrual basis: a sale counts as revenue when you deliver and invoice, not when the customer pays, and an expense counts when it is incurred, not when the bill is paid. That gives a truer picture of performance, but it means profit and cash drift apart. The usual reasons are:

Customers have not paid yet. A $15,000 invoice raised at the end of the month is revenue now and cash later. Growing receivables absorb cash.
Stock is bought before it is sold. Buying inventory is not an expense; it becomes cost of goods sold only when the goods are sold. So buying stock reduces cash without reducing profit. Our guide to inventory management for small business covers how to keep that investment under control.
You have not paid suppliers yet. Bills you owe but have not paid reduce profit but not yet cash, which works in your favor for a while.
Big purchases are spread out. A $20,000 machine is not a $20,000 expense in the month you buy it. It is recorded as an asset and expensed gradually as depreciation, but the cash leaves on the day you pay.
Loans and owner draws. Borrowing brings in cash without being income, and repaying principal or taking a draw sends cash out without being an expense.

None of this means the profit figure is wrong. It answers a different question. Profit tells you whether the business is earning more than it costs; cash flow tells you whether you can pay the bills on Friday.

The indirect method in plain words

There are two ways to present the operating section. The direct method lists actual cash receipts and payments: cash from customers, cash to suppliers, cash to employees. The indirect method starts with net income from the profit and loss statement and adjusts it back to cash. Both are permitted under US GAAP, and the indirect method is the one most small businesses and accounting systems use, because it can be built entirely from the profit and loss statement and the balance sheet.

The indirect method makes two kinds of adjustment:

Add back non-cash expenses. Depreciation and amortization reduced profit, but no cash left when they were recorded. Add them back. Similarly, a gain on selling an asset is removed here, because the full sale proceeds are shown under investing.
Adjust for changes in working capital. An increase in an asset such as receivables or inventory means cash is tied up, so subtract it. A decrease releases cash, so add it. For liabilities such as accounts payable, it works the other way: an increase means you held on to cash, so add it; a decrease means you paid down bills, so subtract it.

A simple way to remember it: assets up, cash down; liabilities up, cash up.

Cash flow statement explained with a worked example

A small wholesale business reports net income of $40,000 for the year. During the year it recorded $6,000 of depreciation, its customers owed it $15,000 more at year end than at the start, it held $8,000 more inventory, and it owed suppliers $5,000 more. It bought a delivery van for $20,000, took out a $10,000 bank loan, repaid $4,000 of loan principal, and the owner drew $9,000. Cash at the start of the year was $12,000.

Cash flow statement for the year	Amount
Operating activities
Net income	$40,000
Add: depreciation	$6,000
Increase in accounts receivable	($15,000)
Increase in inventory	($8,000)
Increase in accounts payable	$5,000
Net cash from operating activities	$28,000
Investing activities
Purchase of delivery van	($20,000)
Net cash used in investing activities	($20,000)
Financing activities
Proceeds from bank loan	$10,000
Repayment of loan principal	($4,000)
Owner draws	($9,000)
Net cash used in financing activities	($3,000)
Net increase in cash	$5,000
Cash at the start of the year	$12,000
Cash at the end of the year	$17,000

Check the arithmetic. Operating: $40,000 + $6,000 − $15,000 − $8,000 + $5,000 = $28,000. Financing: $10,000 − $4,000 − $9,000 = −$3,000. Net change: $28,000 − $20,000 − $3,000 = $5,000. Closing cash: $12,000 + $5,000 = $17,000.

The story is now clear. The business earned $40,000, but $23,000 of it went into customers' unpaid invoices and extra stock, partly offset by $5,000 of slower supplier payments. The van and the owner's draws used most of the rest, and the new loan filled part of the gap. Profit of $40,000 turned into only $5,000 more in the bank.

How to read your cash flow statement monthly

A single cash flow statement is useful. A run of them, month after month, is far more useful. After each month's books are closed (our month-end close checklist covers the steps), work through these questions:

Is operating cash flow positive? Over time, the business should generate cash from its own operations. One negative month can be timing; several in a row need an explanation.
How does operating cash compare with net income? If operating cash is consistently well below profit, look at the working-capital lines to see where the cash is going.
What is happening to receivables? If receivables grow faster than sales, customers are paying more slowly. An aging report shows who is late.
Is inventory building up? Rising stock with flat sales means cash sitting on shelves.
How are investments being paid for? Long-term assets are usually better funded by long-term financing or accumulated operating cash, not by stretching suppliers.
Does closing cash match the bank? The closing figure should agree with your reconciled bank and cash accounts. If it does not, the books are not finished.

For the last point, the statement is only as good as the ledger beneath it. In a double-entry system, every transaction already touches cash or another account, so the cash flow statement can be produced from the books instead of rebuilt in a spreadsheet.

Warning signs to watch for

Profitable on paper, negative operating cash. This often points to slow collections or heavy stock purchases, and it is a common way growing businesses run short of money.
Financing covering operations. If new loans or owner contributions regularly fund day-to-day costs, the business is not yet paying its own way.
Payables rising every month. Paying suppliers later boosts cash for a while, but it cannot continue indefinitely and can damage supplier relationships.
Owner draws larger than operating cash. Taking out more than the business generates shrinks the cash cushion each period.
A one-off sale of assets propping up cash. Investing inflows from selling equipment can make a month look healthy when operations are not.
Cash falling while profit is rising. Look first at receivables and inventory, then at large purchases.

Getting a cash flow statement from your books

If you keep accounts in a double-entry system, you should not have to assemble a cash flow statement by hand. BMS Prime builds the trial balance, profit and loss, balance sheet and cash flow statement straight from its ledger in US dollars, for any period you choose, with month-by-month comparisons and export to PDF, Excel and CSV. It also includes bank reconciliation and receivables and payables aging, which help explain the working-capital lines. BMS Prime does not connect to bank feeds, so the statement is as current as the transactions you have entered.

You can read more about how the accounting fits with HR and inventory on our page for US small businesses. Accounting is included from the Growth plan up, priced per company rather than per user; see pricing for details. However you produce it, with the cash flow statement explained and read every month, you will see a cash squeeze coming well before it reaches your bank balance.

Frequently asked questions

What is the difference between a cash flow statement and a profit and loss statement?

The profit and loss statement records revenue when it is earned and expenses when they are incurred, whether or not cash has changed hands. The cash flow statement shows only money that actually came in or went out, grouped into operating, investing and financing activities. A business can show a profit and still have less cash at the end of the month.

Is depreciation added back on a cash flow statement?

Yes, under the indirect method. Depreciation reduces net income, but no cash leaves the business when it is recorded; the cash went out when the asset was bought, and that purchase appears under investing activities. Adding depreciation back removes a non-cash expense so the operating section reflects only real cash movements.

Where do loan repayments go on a cash flow statement?

The principal part of a loan repayment is a financing activity, because it returns money to a lender. Under US GAAP, the interest part is treated as an operating cash flow, and since interest expense is already included in net income, it does not appear as a separate financing line. Money received from a new loan is also financing.

Should a small business use the direct or indirect method?

Both are allowed under US GAAP. The direct method lists cash received from customers and paid to suppliers and staff. The indirect method starts from net income and adjusts for non-cash items and working-capital changes. Most accounting software and most small businesses use the indirect method, because it comes straight from the profit and loss statement and the balance sheet.

How often should I look at my cash flow statement?

Monthly is a sensible rhythm for most small businesses, right after the books are closed. Compare operating cash flow with net income, check the movement in receivables, inventory and payables, and look at the trend over several months rather than one period. A business with tight cash may also want a weekly look at the bank balance and upcoming payments.
