Income Statement Explained: What Swiss SMEs Can Learn from Their P&L

Your business made a profit last year, but that number alone doesn't tell you very much. How did you make that profit? Is revenue growing? Are costs rising faster than sales? Are your margins improving or getting squeezed? And does the profit shown in your accounts mean you have that money available to spend?

Your income statement can help you answer those questions.

Also known as a profit and loss statement, or P&L, the income statement is one of the main ways to understand how your business is performing financially.

You don't need to become an accountant to use it. You just need to know what you're looking at, and what questions the numbers should make you ask.

Here's how to read an income statement as a business owner.

What is an income statement?

An income statement shows what your business earned, what it spent and whether it made a profit or loss over a particular period. That might be a month, a quarter or a full financial year.

At its simplest: Revenue – costs = profit or loss

Of course, a real income statement contains more detail than that.

Depending on your business and how its accounts are structured, you might see items such as:

• revenue from products or services
• cost of goods or materials
• personnel costs
• rent and premises costs
• software and other operating expenses
• depreciation
• financial income and expenses
• taxes
• profit or loss for the period

But as an owner of a small business, you don't necessarily need to understand every accounting entry to get value from the statement.

Start with three questions: What did we earn? What did it cost us to earn it? 
What was left?

Then start asking why.

That's where the income statement becomes useful for running and growing the business rather than simply recording what happened.

Revenue, costs and profit: the basic logic

The easiest way to read an income statement is from the top down.

You start with the money generated by the business, work through the costs incurred along the way and eventually arrive at a profit or loss.

Revenue: what is the business generating?

Revenue is the income generated through your normal business activities. For a consultancy, that might be client fees. For a retailer, product sales. For a software company, it could include recurring subscription revenue.

Revenue tells you something important about the size and direction of your business, but it doesn't tell you whether the business is profitable.

A company can grow revenue quickly and still make less money if its costs are growing even faster.

So don't stop at the top line - ask what’s driving it.

Did revenue increase because you gained more customers? Increased prices? Sold more to existing customers? Launched a new product or service?

And if revenue fell, where did the decline come from?

The number tells you what happened. Understanding the business behind the number tells you why.

Costs: what does it take to generate that revenue?

Some costs are directly connected with what you sell, whilst others relate to running the company more generally.

Depending on your business, they might include:

• materials or stock
• salaries and other personnel costs
• rent
• insurance
• software
• marketing
• professional services
• equipment and other operating expenses

Again, the individual number isn't always the most interesting part. The trend is.

If revenue rises by 10% but costs rise by 25%, why?

Perhaps you're deliberately investing in people or marketing to support future growth. Perhaps supplier prices have increased. Perhaps you've added software and subscriptions without noticing how much they collectively cost. Or perhaps the business is becoming more expensive to operate as it grows.

None of those conclusions can be drawn from one number alone, but the income statement can tell you where to start looking.

Profit: what's left?

Once the relevant costs have been taken into account, the income statement shows whether the business generated a profit or loss over the period.

Naturally, that's an important number, but don't make the mistake of jumping straight to the bottom of the page.

Two businesses can make the same profit while having very different financial stories behind it. One might have growing revenue and improving margins, whilst another might have falling sales but have temporarily reduced costs.

Understanding how you got to the profit number is one of the most valuable things your income statement can give you.

A simple income-statement example

Imagine a small Swiss services company has the following results for one month

• Revenue - CHF 50,000
• Direct costs - CHF 10,000
• Personnel costs - CHF 20,000
• Other operating expenses - CHF 8,000
• Simplified profit = CHF 12,000

This example is deliberately simplified.

At first glance, the obvious conclusion is: The business generated CHF 12,000 more revenue than the costs shown.But that's only the beginning.

The owner could now ask:

Has revenue increased compared with last month?

• Were the CHF 10,000 of direct costs normal for CHF 50,000 of revenue?
• Are personnel costs changing?
• What's included in the CHF 8,000 of other expenses?
• Is CHF 12,000 a typical result or was this an unusually strong month?
• What happens to the result if revenue falls but salaries and other fixed costs stay broadly the same?

Now imagine that last month's revenue was CHF 45,000 and the comparable costs totalled CHF 31,000. Revenue has increased, but profit has fallen.

That's the kind of information you can miss if you only ask: How much did we sell?

A growing business isn't automatically becoming a more profitable business.

The income statement helps you see the difference.

Income statement vs balance sheet: what is the difference?

The income statement and balance sheet are both important financial statements, but they answer different questions.

A useful way to remember the difference is:

The income statement covers a period. The balance sheet shows a point in time.

Your income statement might show what happened between 1 January and 31 December. Your balance sheet might show the financial position of the business on 31 December.

• The income statement focuses broadly on: revenue → expenses → profit or loss
• The balance sheet focuses on: assets → liabilities → equity

So, your income statement helps you understand how the business performed. Your balance sheet helps you understand its financial position at a particular date - what it owns, what it owes and the equity in the business.

Neither gives you the complete picture on its own. And there's another piece of that picture that matters enormously to a business owner: cash.

Profit is not the same as cash flow

This is one of the most important things to understand when reading an income statement.

Profit does not mean the same thing as cash in your account.

Imagine you complete CHF 20,000 of work for a customer and issue an invoice. That revenue may be reflected in your financial results even though your customer hasn't paid you yet, depending on the applicable accounting treatment.

So your income statement can show revenue and profit while you're still waiting for the actual cash. Meanwhile, you may still need to pay salaries, rent, and suppliers.

The reverse can happen too.

Money moving into or out of your bank account doesn't necessarily become income or an expense on your income statement at the same moment.

That's why a business can be profitable and still experience cash-flow pressure.

And the earlier you can see that pressure building, the more time you have to respond. If you only discover a potential cash shortfall when a major payment is due, your options may already be limited.

As an owner, you need to be able to answer two different questions:

• Is the business profitable?
• Does the business have enough cash to meet its obligations?

Your income statement helps with the first. Your cash-flow information helps with the second.

You need both.

What questions should a business owner ask of the income statement?

You don't need to calculate dozens of ratios every time you receive an income statement. For many SME owners, a handful of practical questions will tell you far more.

1. Is revenue moving in the right direction?

Don't just look at this month's number. Compare it with previous months, quarters or years. If your business is seasonal, compare equivalent periods where possible, and when you see a significant change, ask what caused it.

Understanding that your revenue increased 15% because you gained three major customers, is more insightful than simply acknowledging the 15% increase on it’s own.

2. Are costs growing faster than revenue?

Increasing costs aren't automatically bad. A growing business often needs more employees, marketing, software, premises or professional support. The important question is whether you understand why those costs are increasing and what you expect to get in return.

If revenue rises by 10% while costs rise by 30%, that deserves a closer look. It might represent a deliberate investment. Or it might be the beginning of pressure on profitability.

3. Are your margins changing?

Revenue can rise while profitability deteriorates; that's why margins matter.

Suppose you win substantially more business but need to discount heavily or incur much higher costs to deliver it – the knock on effect is that your company is generating more revenue but not necessarily becoming financially stronger.

Looking at how much profit you're generating relative to revenue, and how that changes over time, can give you a better view of the quality of your growth.

4. Which costs have changed?

Look for movements that stand out.

• Did supplier costs jump?
• Has your software spend gradually increased?
• Did you hire new employees?
• Was there a one-off professional fee?

A change isn't necessarily a problem, but you should be able to explain significant changes in your own business. If you can't, that's a useful signal to investigate.

5. Is this period representative?

Looking at one month in isolation can be misleading. Perhaps you pay an annual insurance premium in March. Maybe December is always your strongest sales month. Perhaps you incurred a one-off legal or consulting cost.

Don't react to every movement as though it represents a new trend. Look at several periods and understand what's normal for your business.

6. What is the income statement telling you to ask next?

This might be the most useful question of all.

Financial statements shouldn't just tell you about the past; they should help you make better decisions about the future. Typical questions related to this might include:

• If margins are declining, do you need to review pricing or costs?
• If revenue is increasing quickly, do you have the resources and cash to support that growth?
• If a particular expense has risen significantly, is it delivering what you expected?
• If profitability is improving, what does that mean for your ability to invest?

The income statement won't make those decisions for you,  but it can help you ask better questions.

Don't read your income statement in isolation

An income statement is useful, but it isn't the entire financial story of your business.

Imagine your P&L shows strong revenue and healthy profit. Now imagine a large proportion of that revenue comes from invoices your customers haven't yet paid. Your profitability might look good while cash is becoming tight. Or perhaps your income statement shows a weaker month because you've made an investment intended to support future growth.

Without context, the result alone can be misleading.

That's why an SME owner should ideally look at the income statement alongside information such as:

• cash available
• outstanding customer invoices
• upcoming supplier payments
• costs and commitments
• balance-sheet information
• historical trends

The objective is to build a more complete picture of what’s happening in the business.

From bookkeeping to ongoing financial visibility

For many SME owners, financial information still arrives retrospectively.

The business sends invoices > Customers pay > Expenses occur > Receipts and documents are collected > Transactions appear in the business account > Accounting records are updated.

And at some point afterwards, the owner sees the financial result.

The closer your financial information is to what's happening in the business today, the more useful it can become for making decisions.

This is where connected financial information matters.

If invoices sit in one system, payments in another and accounting information somewhere else, someone has to connect those pieces before you can see the complete picture.

And that can leave you making decisions using information that's incomplete or out of date.

Helvo is built specifically for how Swiss SMEs do business, bringing key financial processes and information together in one place.

Your business account, payments, invoicing and accounting become part of a more connected financial picture, helping you spend less time piecing information together and giving you greater visibility over what's happening in your business.

The goal isn't to turn you into an accountant. It's to give you a clear, trustworthy view of the numbers behind your business, so they're easier to understand and act on.

Knowing your business made a profit is useful.

Understanding WHY, and WHAT that means for your next decision, is much more valuable.

Frequently asked questions about income statements

What is an income statement in simple terms?

An income statement shows the income and expenses of a business over a particular period and the resulting profit or loss.

In simple terms, it helps you understand what the business earned, what it cost to operate and what was left.

What belongs in an income statement?

The exact structure depends on the business and applicable accounting requirements, but an income statement generally contains revenue and the various expenses incurred during the period, leading to the resulting profit or loss.

For an SME owner, the most important thing is not simply knowing which category each number belongs to, but understanding what changes in those numbers tell you about the business.

What is the difference between a balance sheet and an income statement?

An income statement shows financial performance over a period, while a balance sheet shows the financial position of a business at a particular point in time.

The income statement focuses on revenue, expenses and profit or loss.

The balance sheet focuses on assets, liabilities and equity.

Is profit the same as cash flow?

No.

Profit is an accounting measure of financial performance, while cash flow reflects money moving into and out of the business.

A business can therefore show a profit while experiencing cash-flow pressure, for example, if revenue has been recognised but customers have not yet paid their invoices.

How should a business owner read an income statement?

Start with revenue, costs and profit, but don't stop at the headline numbers.

Compare them with previous periods and ask what has changed and why.

Look at whether revenue is growing, whether costs are increasing faster than sales, how profitability is developing and whether unusual expenses or one-off events have affected the result.

Most importantly, use the income statement to generate questions about the business rather than treating it simply as a historical accounting document.
