Chapter Guide▾

You can get what you need from your three main reports in about 15 minutes a month. Spend five on the profit and loss (did we make money?), five on the balance sheet (what do we own and owe?), three on the cash flow (where did the cash actually go?), and two on writing down what you'll do about it. Below we show how to read financial statements by walking through all three with one small business's numbers, and how they connect.

The business we'll use

Priya runs a mobile dog-grooming business in Newcastle: one van, one employee, and a small line of shampoos she sells to clients. These are her reports for Sep 2026. They're illustrative, but they tie together exactly the way real ones should. Figures exclude GST.

Set a timer. Let's go.

Minutes 0 to 5: the profit and loss

Profit and loss for Sep 2026

Amount
Grooming services$17,600
Product sales$800
Total income$18,400
Grooming products and retail stock$1,900
Gross profit$16,500
Wages and super$7,200
Fuel and van running costs$1,150
Insurance$420
Phone and software$260
Depreciation, van$600
Interest on van loan$180
Total expenses$9,810
Net profit$6,690

Read it top to bottom and ask three things.

1. Is income where I expected? $18,400. Priya knows she did about 160 grooms at around $110, which is $17,600. Tick.

2. What's my gross margin? Gross profit divided by income: $16,500 ÷ $18,400 is about 90%. For a service business with low materials, that's normal. If it dropped to 80% next month without a reason, she'd want to know why.

3. Does any expense look odd against last month? Priya compares to Aug 2026. Fuel was $1,150 both months. Insurance is the same. Nothing jumps. If a line doubled, that's the one to click into.

Net profit: $6,690. That's the business's earnings for the month. It is not how much cash she has. Hold that thought.

Minutes 5 to 10: the balance sheet

Balance sheet at 30 Sep 2026, compared with 31 Aug 2026

30 Sep 202631 Aug 2026
Cash at bank$12,340$8,780
Accounts receivable$4,860$3,660
Van (after depreciation)$38,400$39,000
Total assets$55,600$51,440
Accounts payable$2,150$1,800
GST payable$1,640$1,200
Van loan$24,800$25,620
Total liabilities$28,590$28,620
Net assets$27,010$22,820
Owner's equity at start of month$22,820
Plus net profit for Sep 2026$6,690
Less owner's drawings($2,500)
Total equity$27,010

The balance sheet is a snapshot: everything the business owns, less everything it owes, equals what's left for the owner. Assets of $55,600 less liabilities of $28,590 is $27,010, and the equity section shows how it got there: last month's $22,820, plus this month's $6,690 profit, less the $2,500 Priya took out for herself.

Four quick checks:

  1. Does the bank balance match the bank? $12,340 should be the reconciled balance at 30 Sep 2026. If you haven't reconciled, nothing else on this page can be fully trusted.
  2. Is accounts receivable growing faster than sales? It went from $3,660 to $4,860, up $1,200. Sales were steady. That's worth a look: who's slow to pay?
  3. Is the loan going down? $25,620 to $24,800, down $820. Good, the principal is being repaid and booked correctly.
  4. Can short-term bills be covered? Cash of $12,340 against payables plus GST of $3,790 ($2,150 + $1,640) covers them more than three times over.

A word on GST payable: that $1,640 is GST collected on sales, less GST paid on costs, that hasn't been paid over yet. It sits in your bank account but it isn't yours. Keep GST coded correctly; your BAS agent or accountant handles lodgement.

Minutes 10 to 13: the cash flow

Here's the puzzle. Priya made $6,690 profit, but her bank balance only went up $3,560 ($8,780 to $12,340). The cash flow report explains the gap. This layout starts with profit and adjusts for everything that isn't cash:

Cash flow for Sep 2026

Amount
Net profit$6,690
Add back depreciation (an expense, but no cash left)$600
Increase in accounts receivable (sales not yet collected)($1,200)
Increase in accounts payable (costs not yet paid)$350
Increase in GST payable (collected, not yet paid over)$440
Net cash from operations$6,880
Loan principal repaid($820)
Owner's drawings($2,500)
Net cash from financing($3,320)
Net increase in cash$3,560
Cash at 31 Aug 2026$8,780
Cash at 30 Sep 2026$12,340

It ties to the bank balance on the balance sheet, which is exactly what you want to see. (There was no investing activity this month; if Priya had bought new clippers or a second van, it would sit between operations and financing.)

In plain English, the $3,130 difference between profit and the cash increase is:

  • $1,200 of sales still owed by customers
  • $820 of loan principal, which reduces a debt rather than counting as an expense
  • $2,500 Priya paid herself
  • offset by $600 of depreciation and $790 of bills and GST not yet paid out

Check: $6,690 − $1,200 − $820 − $2,500 + $600 + $790 = $3,560. It all adds up.

Minutes 13 to 15: write down what you'll do

Reports are only worth reading if they change something. Priya's notes for the month:

  • Receivables up $1,200. Run the aged receivables report and send reminders on anything past 14 days.
  • Profit healthy, cash up less. That's fine this month, but she shouldn't plan a big purchase on the profit figure alone.
  • GST of $1,640 sitting in the bank. Mentally park it; it's not spending money.

Three lines. Done in under two minutes.

The 15-minute checklist

MinutesReportQuestions
0 to 5Profit and lossIncome as expected? Gross margin steady? Any expense jump?
5 to 10Balance sheetBank matches reconciliation? Receivables growing? Debts going down? Bills covered?
10 to 13Cash flowWhy is cash change different from profit? Does closing cash equal the bank?
13 to 15Your notesWhat will I do about it this week?

One honest caveat: this works only if the books are reconciled and the month is properly closed. Fifteen minutes on unreconciled numbers just gives you confident wrong answers.

FAQs

Which report should I look at first?

The profit and loss, because it's the most intuitive. But don't stop there; the balance sheet and cash flow catch problems the P&L can't show, like customers paying slowly.

Why is my profit higher than the money in my bank?

Usually because customers owe you money, you've repaid loan principal, you've taken drawings, or you've bought equipment. The cash flow report lists each one.

What's a good gross margin?

It depends entirely on the industry. Service businesses often run high margins; retail and hospitality run much lower. The useful test is whether yours is stable month to month, and if not, why.

How often should I read these reports?

Monthly, after the month is reconciled and closed. Weekly is overkill for most small businesses, though a quick glance at cash and receivables each week doesn't hurt.

Do I need an accountant to interpret them?

Not for a monthly read like this. For bigger decisions such as taking on debt, buying a second van or restructuring, it's worth walking through the numbers with your accountant.

Fifteen minutes, once a month, and you'll know your business better than most owners do.
