A cash flow statement splits every movement of cash into three sections: operating, investing and financing. Read operating first, because it tells you whether the business funds itself. A profitable month with negative operating cash flow is the pattern that catches founders out most often.
The three sections, and what each one is for
Every line in the statement lands in one of three buckets. Operating activities cover cash generated or consumed by running the business. Investing activities cover what you spent on or received from assets, including equipment, capitalised development and acquisitions. Financing activities cover money from and to the people funding you: equity raised, loans drawn and repaid, interest and dividends. The presentation rules are set by the AASB accounting standards, and the obligations on who has to prepare and lodge one sit with ASIC.
Read them in that order, and read the bottom line last. The closing cash balance is the number everyone looks at first and it tells you the least, because a raise and a good trading quarter produce the same figure.
| What the section shows | The question to ask of it | |
|---|---|---|
| Operating | Cash generated or consumed by running the business | Does the business fund itself yet? And if profit and operating cash flow disagree, which working capital line explains the gap? |
| Investing | Cash spent on or received from assets, including equipment, capitalised development and acquisitions | Is this spend building capacity or replacing what wore out? A large outflow here is only alarming if nobody can name what it bought. |
| Financing | Equity raised, loans drawn and repaid, interest and dividends | How much of this period's closing cash came from the business, and how much came from investors or a lender? |
Start with operating cash flow
Operating cash flow answers the only question that matters early on: does the business fund itself, or is it being funded. Most statements present it indirectly, starting at profit and adding back non-cash items like depreciation, then adjusting for movements in receivables, payables and inventory. Those working capital movements are usually where the story is, and they are the lines founders skim.
For founders and CFOs scaling fast, often on external funding, burn rate is front of mind every month.[1] That is exactly the moment the statement stops being a compliance artefact and starts being the thing the board runs on, which is also when the gaps in who prepares it become expensive.
The pattern that catches people out
Profitable on the P&L, negative on operating cash flow. It is not an error and it is not rare. It happens when revenue is recognised on invoice while customers pay in sixty days, when inventory is built ahead of a season, or when growth itself consumes working capital faster than it produces margin. A business can grow into insolvency while every monthly P&L looks fine.
The reverse pattern deserves the same scrutiny. Strongly positive operating cash flow alongside a loss can mean a large deferred revenue balance, which is cash collected for work not yet delivered. In a subscription business that is normal. It is still a liability, and spending it as though it were earned is how a good quarter turns into a bad year.
The two statements have to be read together, which is why what a profit and loss statement contains is the companion to this page.
Who should be explaining this in your business
Founder-led finance does not scale at all. It eventually runs its course as the business grows, and the symptoms are consistent: a scrambled financial model, and cash conversations that are more of a guess than an answer.[2] It is a starting point I hear about often from the finance leaders I interview on The CFO Track. If nobody can tell you today what operating cash flow was last month and why it moved, the statement is not the problem.
What a founder is really buying at that point is someone who has carried this before. In the early-stage CFO and Head of Finance briefs I run, the attributes that decide it are direct ownership and operational experience alongside the strategic work, being the founder's commercial and strategic eyes and ears, and demonstrated credibility with banks, funders or investors.[3] That last point is cash flow specifically. On one interim CFO brief, the three requirements were a project infrastructure background, cash flow management including working capital and bank relations with refinancing experience, and previous acquisition experience.[4] Those are not generic finance skills. They are the ones you hire for when the cash question has teeth.
If cash conversations have started to feel like guesswork, that is a hiring signal. Here is when to make your first senior finance hire.
Common questions
What are the three sections of a cash flow statement?
Operating, investing and financing. The split exists so that a reader can tell where a bank balance came from, because all three sections can produce an identical closing figure for completely different reasons. Cash from trading, cash from selling an asset and cash from a raise all land in the same account and mean nothing like the same thing. Read operating first, since it is the only section that answers whether the business funds itself, and read the closing balance last.
How can a business be profitable and still run out of cash?
Because a profit and loss statement is prepared on an accruals basis, so revenue counts when it is earned rather than when the money arrives. The gap between the two is working capital, and it is a genuine cost of growing rather than an accounting quirk: every extra dollar of revenue sold on sixty-day terms is a dollar you fund for two months before you ever see it. That is why growing quickly drains cash faster than growing slowly, and why the profit line gives no warning at all.
What does negative operating cash flow mean?
That the business consumed cash in the ordinary course of trading over the period. For an early-stage company burning investor money that is expected and the useful question is the trend and the runway it implies. In an established business it means either working capital has moved against you or the trading itself is not covering its costs, and those two have completely different fixes.
Who should prepare and explain the cash flow statement in a startup?
Preparation sits with whoever owns the close, usually a financial accountant, controller or an outsourced provider early on. Explaining it is a different job and belongs to the senior finance person, because the board wants the reason for the movement rather than the movement. When founders are still assembling that answer themselves, it is usually the clearest signal that the first proper finance hire is overdue.
