There is a document that your accountant prepares for you every year — possibly every month — that has the power to transform the way you run your business. It tells you whether you are actually making money. It tells you where your costs are going. It tells you whether your business model is working.
Most South African business owners never read it properly. Some avoid it entirely. Some glance at the bottom line, see a number and move on without understanding what it means or what produced it.
That document is your income statement or Profit and loss statement. These are interchangeable terms. Different people and accounting software call the same report slightly different names. In this post I am going to walk you through it in plain language — no jargon, no accounting qualifications required — so that the next time your accountant sends it through, you know exactly what you are looking at and what questions to ask.
This is the first post in our financial literacy mini-series. Part two — covering the cash flow statement — is coming later in the series. Together they give you the two most important financial documents every business owner should understand.
What the profit and loss statement actually tells you
The income statement tells you whether your business made a profit or a loss over a specific period — usually a month, a quarter or a financial year. It does this by listing all your income at the top and then subtracting your costs layer by layer until you arrive at a final profit or loss figure at the bottom.
Think of it like a waterfall. Money flows in at the top as revenue. Then it gets reduced by costs at each level. What flows out at the bottom — if anything — is your profit.
The income statement does not tell you how much cash you have. That is a common and costly confusion — which is why the cash flow statement exists and why we will cover it separately. The income statement tells you about profitability. The cash flow statement tells you about liquidity. Both matter. Neither replaces the other.
Profit and cash are not the same thing. Your income statement tells you one. Your cash flow statement tells you the other. A business can be profitable and still run out of cash — and many business owners do exactly that.
The anatomy of an profit and loss statement
Here is what each line of your income statement means, in the order they appear:
| Revenue/Turnover / Sales | The total money your business earned from sales before any costs are deducted. This is the top line. It tells you how much you billed or invoiced less VAT (see explanation below)— not how much you kept. |
| Cost of Sales | The direct costs you incurred to make a sale of your product or service — materials, direct labour, subcontractors. These costs go up and down with your revenue. |
| Gross Profit | Revenue minus Cost of Sales. This is what your business earns before all the other expenses. Your gross profit margin (gross profit ÷ revenue) tells you how efficiently you deliver your service. |
| Operating Expenses | The fixed costs of running your business — rent, salaries, marketing, insurance, software subscriptions, accounting fees. You will pay these expenses whether or not you make a sale. |
| Operating Profit (Nett profit before tax) | Gross Profit minus Operating Expenses. This shows whether your core business operation is profitable before interest and tax. |
| Interest and Tax | Interest on any loans or overdrafts, plus your income tax expense for the period. Both are deducted after operating profit. |
| Net Profit | What is left after everything — including interest and tax — has been paid. This is the bottom line. It is what your business actually earned for the period. The “bottom line”. |
A worked example
Here is what a simplified income statement might look like for a South African service business with R850 000 in annual revenue:
| Revenue | R 850 000 |
| Cost of Sales | (R 340 000) |
| Gross Profit | R 510 000 |
| Gross Profit Margin | 60% |
| Operating Expenses | (R 380 000) |
| Operating Profit (EBIT) | R 130 000 |
| Interest and Tax | (R 42 000) |
| Net Profit | R 88 000 |
| Net Profit Margin | 10.4% |
What does this tell us? The business has a healthy gross margin of 60% — meaning for every rand of revenue, 60 cents is available to cover overheads after direct costs. Operating expenses of R380 000 leave an operating profit of R130 000. After interest and tax, the net profit is R88 000 — a net margin of just over 10%.
Is that good? That depends on the industry, the growth stage of the business and what the owner is paying themselves. But it is a business that is profitable — and one where the owner can now ask intelligent questions about which costs are necessary and where margin improvement is possible.
The questions worth asking when you read your income statement (profit and loss statement)
Reading the numbers is the first step. Knowing what questions to ask is the second. Here are the four questions I encourage every business owner to ask when they look at their income statement:
| Is my gross profit margin healthy for my industry? | If your margin is thin, even a small drop in revenue (or rise in expenses) can wipe out your profit entirely. |
| Are my operating expenses growing faster than my revenue? | If costs are rising faster than income, your profitability is being squeezed even if your revenue looks good. This is one of the most common hidden problems in growing businesses. |
| What is my net profit margin? | Net profit ÷ revenue. This again depends on the industry but below 5% is a warning sign that your business model needs attention. |
| Am I comparing this month to the same month last year? | Many South African businesses are seasonal. Comparing May to April may be misleading. Comparing May to last May tells you something real. This good as a starting point. |
What to do if you do not receive a monthly income statement
If your accountant only sends you an income statement once a year — at year end — you are effectively flying blind for twelve months at a time. By the time you see a problem in an annual report of some kind, it has usually been building for six to nine months.
Monthly accounts — which include your profit and loss statement and other reports — are the standard we hold all our BCAS clients to. They are not a luxury. They are the minimum information you need to run a business with any degree of confidence. They are also able to look at the reports themselves as we have explained to them how to do it.
If you are using Xero, you can generate your income statement yourself at any time — today, right now, for whatever period you choose. It is called the Profit and Loss report in Xero and it is one of the most used reports in the platform. You do not have to wait for your accountant to prepare it. You can run it yourself and check in weekly if you want to.
If you only see your income statement once a year, you are not managing your business — you are just hoping for the best. Monthly accounts change everything.
A note on VAT
One point worth clarifying for South African business owners: your income statement should show your revenue and costs excluding VAT. VAT is not income — it belongs to SARS. If your income statement includes VAT in your revenue figure, the numbers will look inflated. Make sure your Xero settings are handling this correctly. It is setup as standard.
Making the income statement work for you
The income statement is not just a historical document. It is a management tool. When you read it regularly — monthly, ideally — and when you understand what each line means, it starts to tell you things. It tells you when your cost of sales is creeping up, which might mean a supplier has increased prices or a project ran over budget. It tells you when your operating expenses are growing faster than your revenue, which is a profitability warning. It tells you whether the gross margin you are achieving reflects the pricing strategy you intended.
This is what financial clarity actually looks like in practice. Not a vague sense of whether things are going well — but a specific, accurate, up-to-date picture of your business performance that you can act on.
In the next post we will look at Xero versus spreadsheets — a comparison that comes up constantly when we speak to business owners who are considering making the switch. If you found this post useful, send it to someone who may benefit from it. Look out for the next chapter in the series
