Module 5 — The three financial statements and how to read them
Level: Intermediate · Duration: 5 hours · Tracks: 🟢 🔵 🟣 · Prerequisite: Module 2 (and Module 4 for the 🔵🟣 tracks)
1. Objectives
By the end of this module you will be able to:
- Prepare an income statement, a balance sheet and a cash flow statement from a trial balance.
- Explain how the three statements link to each other, and check your work with three linking points.
- Prepare a cash flow statement by the indirect method and explain the gap between profit and cash.
- Calculate and read nine core financial ratios for an e-commerce store.
- Read a store's income statement and judge, in 60 seconds, what its biggest problem is.
2. Core concepts
2.1 Three statements answering three questions
| Statement | The question | Its nature |
|---|---|---|
| Income statement | Did I make a profit during the period? | A film — it covers a period |
| Balance sheet | What do I own and what do I owe right now? | A photograph — a single moment |
| Cash flow statement | Where did the cash actually go? | A film — it covers a period |
2.2 The shape of an income statement for an e-commerce store
Gross sales
− Sales returns and discounts
─────────────────────────────
= Net revenue
− Cost of goods sold
─────────────────────────────
= Gross profit ──▶ measures the health of your pricing and your buying
− Fulfilment costs (payment fees, delivery, platform commissions)
─────────────────────────────
= Contribution margin ──▶ measures the profitability of a single order
− Marketing expense
─────────────────────────────
= Profit after marketing ──▶ measures acquisition efficiency
− Fixed costs (salaries, rent, software, professional fees, depreciation)
─────────────────────────────
= Net profit before tax
Why this shape in particular? The standard order (revenue − cost − administrative expenses) tells a store founder nothing. The order above separates what changes with every order (variable) from what does not (fixed), and that is the only separation that lets you calculate your break-even point and estimate the effect of doubling your sales.
2.3 The three linking points between the statements
Income statement Balance sheet Cash flow
Net profit ────────▶ Retained earnings
Cash ◀──────────────── Closing cash balance
Depreciation ──────▶ Accumulated depreciation ──────▶ added back (non-cash)
The three checking rules — if one of them fails, your work is wrong:
Assets = Liabilities + EquityClosing retained earnings = opening + net profit − distributionsClosing cash in the cash flow statement = the cash balance on the balance sheet
2.4 Cash flow by the indirect method
You start from net profit and adjust it until you reach cash:
Net profit
+ Non-cash expenses (depreciation, provisions)
± The change in working capital:
an increase in an operating asset (inventory, receivables, prepayments) → subtract
an increase in an operating liability (payables, accruals, taxes) → add
─────────────────────────────
= Cash from operating activities
± Investing activities (buying/selling fixed assets)
± Financing activities (capital, loans, distributions)
─────────────────────────────
= Net change in cash
The logic in one sentence: an increase in inventory means cash turned into goods ⇒ cash went out ⇒ subtract. An increase in payables means you took goods and did not pay ⇒ the cash stayed with you ⇒ add.
2.5 The nine ratios for an e-commerce store
| Ratio | The formula | What it says | Rough benchmark |
|---|---|---|---|
| Gross profit margin | Gross profit ÷ net revenue | The health of pricing and buying | 40–70% |
| Contribution margin | (Gross profit − fulfilment costs) ÷ revenue | The profitability of an order | > 35% |
| Net profit margin | Net profit ÷ net revenue | Final profitability | 5–15% |
| Marketing-to-revenue ratio | Marketing ÷ revenue | Acquisition efficiency | < 25% |
| Inventory turnover | Cost of goods sold ÷ average inventory | How fast goods turn into cash | > 4 per year |
| Inventory days | 365 ÷ turnover | How many days your cash sits as goods | < 90 days |
| Current ratio | Current assets ÷ current liabilities | The ability to pay short-term debts | > 1.5 |
| Return rate | Returns ÷ gross sales | Product and description quality | < 5% |
| Operating cash conversion | Operating cash ÷ net profit | The quality of earnings | > 0.8 |
3. Worked example — the three statements for Nuwa, January 2026
3.1 Income statement for the month ended 31 January 2026
| Item | Amount (dirhams) | % of revenue |

| Less: cost of goods sold | (33,120.00) | (34.7%) |
| Gross profit | 62,400.00 | 65.3% |
| Payment gateway fees | (2,388.00) | (2.5%) |
| Delivery expenses | (1,500.00) | (1.6%) |

| Net profit before tax | 24,312.00 | 25.5% |
3.2 Balance sheet as at 31 January 2026
| Assets | Amount | Liabilities and equity | Amount |
|---|---|---|---|
| Current assets | Current liabilities | ||
| Bank | 184,853.60 | Accounts payable | 30,000.00 |
| Inventory | 35,880.00 | Accrued expenses | 2,500.00 |
| Prepaid expenses | 15,000.00 | VAT payable (net) | 2,421.60 |
| Total current | 235,733.60 | Total current | 34,921.60 |
| Non-current assets | Non-current liabilities | ||
| Equipment (at cost) | 24,000.00 | Related-party loan | 50,000.00 |
| Less: accumulated depreciation | (500.00) | Total liabilities | 84,921.60 |
| Net equipment | 23,500.00 | Equity | |
| Paid-in capital | 150,000.00 | ||
| Retained earnings | 24,312.00 | ||
| Total equity | 174,312.00 | ||
| Total assets | 259,233.60 | Total | 259,233.60 |
A presentation note: VAT is presented on the balance sheet net (output 8,526.00 − input 6,104.40), while it stays as two separate accounts in the books. That is the difference between presentation and recording, and it confuses a lot of people.
3.3 Cash flow statement (indirect) for January 2026
| Item | Amount (dirhams) |
|---|---|
| Operating activities | |
| Net profit | 24,312.00 |
| Add: depreciation expense (non-cash) | 500.00 |
| Change in inventory (increase) | (35,880.00) |
| Change in prepaid expenses (increase) | (15,000.00) |
| Change in accounts payable (increase) | 30,000.00 |
| Change in accrued expenses (increase) | 2,500.00 |
| Change in net VAT (increase) | 2,421.60 |
| Net cash from operating activities | 8,853.60 |
| Investing activities | |
| Purchase of equipment | (24,000.00) |
| Net cash used in investing | (24,000.00) |
| Financing activities | |
| Paid-in capital | 150,000.00 |
| Loan from the founder | 50,000.00 |
| Net cash from financing | 200,000.00 |
| Net increase in cash | 184,853.60 |
| Cash at 1 January | 0.00 |
| Cash at 31 January | 184,853.60 |
The triple check:
1. Assets 259,233.60 = liabilities 84,921.60 + equity 174,312.00 ✓
2. Retained earnings 0 + 24,312.00 − 0 = 24,312.00 ✓
3. Closing cash 184,853.60 = the bank balance on the balance sheet ✓
3.4 The reading — what do these statements actually say?
| Indicator | Value | The verdict |
|---|---|---|
| Gross profit margin | 65.3% | Excellent — pricing is sound and landed cost is properly calculated |
| Contribution margin | 61.3% | Strong — fulfilment costs are only 4.1% of revenue |
| Marketing-to-revenue ratio | 15.7% | Healthy, with room to expand |
| Net profit margin | 25.5% | High, but be careful — the first month carries less than a full cost base |
| Return rate | 4.0% | Acceptable, keep watching it |
| Current ratio | 6.75 | Very high liquidity — idle cash that could be put into inventory |
| Operating cash conversion | 0.36 | The red flag |
The red flag explained: every dirham of profit produced only 36 fils of cash. The cause is not sickness, it is growth: inventory and prepaid rent swallowed 50,880 dirhams. But the number carries a real warning — if the store keeps growing at this pace and its supplier stops granting 30 days of credit, it will need extra cash before it feels any problem at all in the income statement.
The decision that follows: fix the supplier's credit terms in writing before you scale your orders, and start now on a 13-week cash forecast (Module 10).
4. Exercises
E5.1 — The income statement (beginner). From the following trial balance, prepare an income statement in the stepped shape:
sales 240,000 · returns 14,400 · cost of goods sold 96,000 · gateway fees 5,600 · delivery 7,200 · platform commissions 9,800 · marketing 46,000 · salaries 28,000 · rent 6,000 · software 2,400 · depreciation 1,100.
Calculate: net revenue, gross profit, contribution margin, profit after marketing, net profit, and four percentages.
E5.2 — The balance sheet (beginner→intermediate). Arrange the following into a properly classified balance sheet:
bank 88,400 · inventory 132,000 · receivable from the payment gateway 21,300 · equipment 40,000 · accumulated depreciation 6,500 · accounts payable 74,000 · tax payable 9,100 · long-term bank loan 60,000 · capital 100,000 · retained earnings ?
Calculate retained earnings, then the current ratio, and comment on it in two lines.
E5.3 — Cash flow (intermediate). Net profit 45,000 · depreciation 3,000 · inventory rose from 60,000 to 96,000 · accounts payable rose from 40,000 to 52,000 · the receivable from the gateway rose by 8,000 · asset purchases 15,000 · distributions to the owner 20,000. Prepare the statement, calculate the net change in cash and the cash conversion ratio, then explain the result in two lines.
E5.4 — Fast diagnosis (intermediate). Three stores, each with revenue of 500,000:
| Store A | Store B | Store C | |
|---|---|---|---|
| Gross profit | 300,000 | 150,000 | 290,000 |
| Fulfilment costs | 25,000 | 30,000 | 85,000 |
| Marketing | 60,000 | 55,000 | 70,000 |
| Fixed costs | 190,000 | 50,000 | 100,000 |
For each store: calculate net profit, name the single biggest problem, and propose one specific action that can be carried out within 30 days.
E5.5 — Linking the statements (advanced). A store: opening retained earnings 82,000, closing 96,500, and 12,000 distributed to the owner. What was the net profit for the period? Then: opening cash 40,000 and closing cash 31,000, operating cash was +18,000 and financing was −12,000. What was the investing cash flow? And what most likely happened?
5. Mini project — "The monthly financial pack"
Deliverable: three statements linked automatically + a one-page summary.
What is required:
- Build the three statements in a single file, all of them reading from the trial balance through formulas — with no manual entry.
- Add the three check cells (balance sheet balances, retained earnings, cash agreement) showing ✓ or the difference.
- Add a dashboard of the nine ratios with a colour indicator for each ratio against its benchmark.
- Write a summary page for an investor or a partner: the three most important numbers, the biggest risk, and the proposed action — with no accounting jargon.
- A sensitivity test: change January sales from 99,500 to 150,000 while keeping costs at a constant percentage, and record what happened to net profit and to operating cash. Explain why the two did not move by the same percentage.
Acceptance criteria:
- [ ] The three statements match the worked example's figures exactly.
- [ ] All three check cells show ✓.
- [ ] No numeric cell in the statements is typed by hand — all of them are formulas from the trial balance.
- [ ] The summary page contains no unexplained accounting jargon.
- [ ] The explanation of the sensitivity test mentions working capital explicitly.
6. The test
10 questions · pass 7/10.
-
Which of the statements cover a period, and which one pictures a single moment?Nuwa's balance sheet says what you own and what you owe on 31 January only; it does not say how you got there. Performance is read from a film (the income statement and the cash flow statement), not from a photograph.
-
A store made a profit of 60,000 and its operating cash was 5,000. Which explanation is sound accounting?It is exactly Nuwa's own gap: profit of 24,312.00 and operating cash of 8,853.60, because inventory and prepaid rent swallowed 50,880 dirhams. Every increase in an operating asset is subtracted from cash.
-
Why is depreciation expense added back in the cash flow statement under the indirect method?The indirect method starts from net profit and then strips out everything that is not cash. Nuwa's depreciation of 500.00 reduced profit and did not take a single dirham out of the bank, so it is added back.
-
What is the difference between gross profit and contribution margin in an e-commerce store?Nuwa's gross margin is 65.3% while its contribution margin is 61.3%, because gateway fees and delivery of 3,888.00 dirhams are paid on every order. Your pricing decision has to cover those too.
-
Revenue 300,000 and cost of goods sold 105,000. What is the gross profit margin?Gross profit = 300,000 − 105,000 = 195,000, and the margin = 195,000 ÷ 300,000 = 65.0%. The denominator is always net revenue, never the cost.
-
A profitable store has a current ratio of 0.7. What does that mean?Current ratio = current assets ÷ current liabilities, and the benchmark is above 1.5 (Nuwa is at 6.75). At 0.7, every dirham due within a year is backed by only 70 fils.
-
Where does VAT payable appear in the statements, and why is it not an expense?On Nuwa's balance sheet it shows as 2,421.60 = output 8,526.00 − input 6,104.40, while the books keep two separate accounts. It is the difference between presentation and recording, nothing more.
-
Opening retained earnings 50,000, net profit 30,000, distributions 10,000. What is the closing balance?Closing = opening + net profit − distributions = 50,000 + 30,000 − 10,000 = 70,000. This is the second of the three checking rules.
-
A store has an inventory turnover of 2.1 per year. What are its inventory days, and what is the verdict?Inventory days = 365 ÷ turnover = 365 ÷ 2.1 = 173.8 days. Divide by 365, do not multiply by it, and the year is 365 days, not 30.
-
Your balance sheet is out of balance by 4,500. What are the first three places you check, and in what order?The order runs from the widest to the narrowest: a trial balance that is off means an entry is missing a side, an amount equal to half the difference (2,250) reveals an entry posted on the wrong side, and the most common presentation error is carrying net profit into retained earnings incorrectly.
Pass mark 7 of 10.
7. Completion standard
| # | The standard | The evidence |
|---|---|---|
| 1 | A correct stepped income statement with its percentages | E5.1 + the project |
| 2 | A balanced, correctly classified balance sheet (current/non-current) | E5.2 + the project |
| 3 | An indirect cash flow statement ending in cash that matches the balance sheet | E5.3 + the project |
| 4 | The three check cells work and catch a deliberately planted error | The project file |
| 5 | Diagnosing 3 out of 3 stores in E5.4 with a specific, executable action | The exercise sheet |
| 6 | You read a new income statement and name its biggest problem within 60 seconds | A timed exercise |
| 7 | Test score ≥ 7/10 | The test sheet |
Mastery level (optional): prepare the three-statement pack for your real store for the last completed month, and show it to someone who does not understand accounting. If, after reading it, they cannot tell you whether the month was good or bad and why, the problem is in your presentation, not in their understanding.
