The Cash Flow Statement
Following the Money Through Your Business
By Matthew Dettman, ChFC, CLU, founder of Second Difference Solutions. Updated .
What Is a Cash Flow Statement?
The Cash Flow Statement tracks the actual movement of cash into and out of your business over a period of time. While the P&L can show a profit on paper, the Cash Flow Statement reveals whether that profit translated into real money you can spend.
Why Cash Flow Matters More Than Profit
Profitable businesses fail every day. Not because they weren't making money on paper, but because they ran out of cash to pay their bills. Consider:
- You invoice a customer for $50,000. That's revenue on your P&L
- But they pay in 60 days, so you don't have the cash for 2 months
- Meanwhile, you need to pay suppliers, employees, and rent NOW
The Three Types of Cash Flow
Operating Activities
Day-to-day business
Cash generated (or used) by your core business operations: selling products, providing services, and paying operating expenses.
Examples
- Customer payments+ Inflow
- Vendor payments− Outflow
- Payroll− Outflow
- Rent, utilities− Outflow
Investing Activities
Long-term assets
Cash spent on or received from buying and selling long-term assets like equipment, property, or investments.
Examples
- Buy equipment− Outflow
- Sell old vehicle+ Inflow
- Purchase property− Outflow
- Invest in securities− Outflow
Financing Activities
Debt and equity
Cash from borrowing, loan repayments, owner investments, and owner withdrawals. How you fund the business.
Examples
- New loan proceeds+ Inflow
- Loan repayments− Outflow
- Owner investment+ Inflow
- Owner draws− Outflow

Reading the Numbers: What This Tells Us
The Story: This business generated strong cash from operations ($99,238). It invested heavily in equipment ($66,500), largely funded by a new loan ($71,184). After the owner took $11,000 for personal use, the business still increased its cash position by nearly $93,000.
Understanding the Adjustments
The Cash Flow Statement starts with Net Income from the P&L, then adjusts for things that affect profit but not cash:
Why Add Depreciation?
Depreciation reduced Net Income on the P&L, but no cash actually left the business. It's a paper expense, so we add it back. In our example: $17,085 in depreciation is added back.
Why Subtract Receivables Increase?
Rising A/R means you recorded revenue (P&L) that hasn't turned into cash yet. We subtract this because the cash hasn't arrived. In our example: $14,329 subtracted.
Why Add Payables Increase?
Rising A/P means you recorded expenses (P&L) but haven't paid cash yet. The cash is still in your account, so we add it back. In our example: $6,134 added.
Why Subtract Inventory Increase?
Buying inventory uses cash, but doesn't hit the P&L until items are sold. Rising inventory means cash left for products still on the shelf. In our example: $1,164 subtracted.
Cash Flow Health Scenarios
Healthy: Positive Operating Cash
Operations generate enough cash to fund investments and repay debt. The business is self-sustaining. Our example shows this pattern: operations produced $99K, more than enough to cover investments.
Watch: Growth Funded by Debt
Negative operating cash but positive financing (new loans). May be OK for rapid growth, but unsustainable long-term. The business depends on outside money to survive.
Danger: Cash Drain Everywhere
Negative operating, investing, AND financing. The business is burning through existing cash reserves. Without changes, this leads to cash-out and failure.
Free Cash Flow: The Key Metric
Free Cash Flow represents money available for:
- Paying dividends or owner distributions
- Reducing debt
- Making acquisitions
- Building cash reserves
A positive Free Cash Flow means your operations generate enough to maintain and grow the business without outside funding. In our example, the business generated $32,738 in free cash after investing in new equipment.
Cash Flow vs. Profitability
| P&L Shows | Cash Flow Reveals |
|---|---|
| Revenue earned | Cash collected from customers |
| Expenses incurred | Cash paid to vendors |
| Depreciation expense | No cash impact, add back |
| Net Income (accrual) | Actual cash generated |

What to Look For Each Month
When reviewing your Cash Flow Statement, ask these questions:
Operating Activities
- Is operating cash flow positive? (Should be for sustainable business)
- Is it higher or lower than net income? (Higher is better; it means profit is real)
- Are receivables growing faster than revenue? (Warning sign)
Investing Activities
- Are you investing enough in the business?
- Can operations fund your capital needs?
- Are you liquidating assets to fund operations? (Concern)
Financing Activities
- Is debt increasing or decreasing?
- How much are owners taking out vs. leaving in?
- Are you too dependent on loans?
The Cash Conversion Cycle
How long does it take to turn inventory into cash?
- Days Inventory Outstanding: How long items sit before selling
- Days Sales Outstanding: How long customers take to pay
- Days Payables Outstanding: How long you take to pay vendors
Cash Conversion Cycle = DIO + DSO − DPO
Lower is better. A negative number means vendors are effectively financing your operations.
Worked Example: Following the Demo Company's Cash
The free 2diff Business demo runs on the books of a fictional landscaping company. This is its statement of cash flows for 2025, taken from the same data the demo loads, so every number below can be found in the demo. Amounts are rounded to the dollar.
| Line | 2025 |
|---|---|
| Net income | $81,765 |
| Add back depreciation (equipment and truck) | $17,085 |
| Increase in accounts receivable | ($15,279) |
| Increase in inventory and prepaid expenses | ($1,564) |
| Increase in payables, credit card and payroll liabilities | $12,263 |
| Net cash from operating activities | $94,269 |
| Equipment and truck purchases | ($66,500) |
| Net cash from investing activities | ($66,500) |
| New note payable | $71,184 |
| Owner draw | ($11,000) |
| Net cash from financing activities | $60,184 |
| Net increase in cash | $87,953 |
| Cash at beginning of year | $129,711 |
| Cash at end of year | $217,664 |
Step 1: Start from profit
The statement opens with net income of $81,765, the bottom line of the profit and loss statement for the same year. Everything after this line explains why the bank balance moved by a different amount.
Step 2: Add back what cost no cash
Depreciation on the equipment and the truck reduced profit by $17,085, yet no money left the business for it in 2025; the cash went out when the assets were bought. So the statement adds it back.
Step 3: Account for working capital
Customers owed $15,279 more at year end than at the start, so that much revenue was booked but not yet collected. Inventory and prepaid costs absorbed another $1,564. On the other side, the company owed vendors, its credit card and payroll taxes $12,263 more than a year earlier, which kept that cash in the bank for now. Net, working capital used $4,581.
Step 4: Judge the operating result
Operating activities produced $94,269, which is 1.15 times net income. Cash from operations above profit is a healthy sign: the profit is real money, not just invoices. The $17,085 depreciation add-back more than explains the $12,504 gap, since working capital took $4,581 back, so it is worth checking the same ratio over several years. In the four years before, the demo company's operating cash ran just under its net income each year, for example $44,599 against $44,756 in 2024.
Step 5: Follow the big decisions
The company spent $66,500 on equipment and a truck and borrowed $71,184 on a note. The owner took $11,000 out. Free cash flow, operating cash minus capital spending, was $27,769. Operations alone covered the equipment with money to spare, so the loan added to the cash cushion rather than filling a gap. Whether that cushion is worth the interest is a question for the owner and their accountant.
Step 6: Tie it to the balance sheet
Cash at the start of the year was $129,711. Add the net increase of $87,953 and you get $217,664, which is exactly the bank account total on the 2025 balance sheet in the balance sheet guide's worked example. If the two do not match on your own statements, a transaction is missing or posted to the wrong account.
Using the day counts 2diff Business calculates, the same company's cash conversion cycle at the end of 2025 was about 100 days to collect, plus 47 days of inventory, minus 101 days to pay vendors: roughly 46 days from paying for work to being paid for it.
Cash Flow Questions
Why is my bank balance lower than my profit?
Profit counts revenue when it is earned and expenses when they are incurred. Cash moves when customers pay and when you pay. Unpaid invoices, inventory on the shelf, loan principal payments, equipment purchases and owner draws all use cash without reducing profit by the same amount, so the bank balance can trail profit for months. The operating section of the cash flow statement shows which of these is responsible.
How do I calculate free cash flow for a small business?
Take net cash from operating activities and subtract what you spent on equipment, vehicles and other long-term assets during the same period. In the worked example above, $94,269 minus $66,500 leaves $27,769. A positive figure means operations paid for the investment without new money from a lender or the owner.
Does depreciation affect cash flow?
Not directly. Depreciation spreads the cost of an asset over its useful life on the profit and loss statement, but the cash left when the asset was bought. That is why the cash flow statement adds depreciation back to net income. It can affect cash indirectly through taxes, which is a question for your tax preparer.
How often should I review my cash flow statement?
Monthly, beside the profit and loss and the balance sheet. Look at whether operating cash is positive and how it compares with net income, then at any large investing or financing line. Comparing the same months year over year shows seasonal patterns that a single month hides.
