Two different snapshots of the same business
The balance sheet and the profit and loss account (P&L) aren’t competing with each other: they answer different questions. The balance sheet is a fixed snapshot at a specific moment (“what do you have and owe today?”). The P&L is a film of a period (“what came in and went out over these months, and what profit is left?”). You need both to get a real picture of how your business is doing.
The balance sheet, in three blocks
- Assets: everything the business owns (cash in the bank, invoices pending collection, equipment, premises, stock…). Ordered from most liquid (cash) to least liquid (fixed assets).
- Liabilities: everything the business owes to others (suppliers, loans, the tax office, social security).
- Equity: what’s left once you subtract liabilities from assets — in simple terms, the part of the business that’s actually “yours”.
The equation that always holds is Assets = Liabilities + Equity. If a balance sheet doesn’t add up, there’s an error somewhere, not an exception to the rule.
The P&L, from top to bottom
The profit and loss account starts from your income and subtracts costs in blocks until it reaches the final profit (or loss):
- Sales revenue.
- Minus the direct cost of what was sold → gross margin.
- Minus overheads (rent, utilities, accounting fees, marketing…) → operating result.
- Minus financial expenses (loan interest) and adjustments → result before tax.
- Minus the corresponding tax (personal income tax if you’re self-employed under direct assessment, corporate tax if you have a limited company) → net result for the year.
The first thing worth checking in each one
On the balance sheet: whether your current assets (what you can turn into cash within a year) cover your current liabilities (what you have to pay within a year). If they don’t, you have a liquidity problem even if the business is profitable on paper.
On the P&L: whether the operating result (before interest and tax) is positive. A business can show a final profit thanks to a one-off item (selling an asset, for example) and still have a structural problem in its core activity — the operating result is what tells you whether the “day-to-day” business actually works.
A simple example, with both documents at once
Imagine a quarter with these numbers:
P&L for the quarter
| Item | Amount |
|---|---|
| Sales revenue | €12,000 |
| Direct cost of goods sold | −€3,000 |
| Gross margin | €9,000 |
| Overheads (rent, accounting, marketing…) | −€4,000 |
| Operating result | €5,000 |
| Financial expenses | −€200 |
| Result before tax | €4,800 |
| Tax (approx.) | −€960 |
| Net result for the period | €3,840 |
Balance sheet at quarter-end
| Assets | Liabilities + Equity | ||
|---|---|---|---|
| Cash | €2,000 | Suppliers | €1,200 |
| Accounts receivable (unpaid invoices) | €3,500 | Loan | €2,000 |
| IT equipment | €1,500 | Equity | €3,800 |
| Total assets | €7,000 | Total | €7,000 |
The quarter closes with €3,840 in profit — good news on paper. But the balance sheet shows the other side: of that €7,000 in assets, only €2,000 is actually cash; €3,500 is invoices issued and still unpaid. If that client is slow to pay, the business could run into a liquidity problem next month even though the P&L says it was profitable. That’s exactly the kind of combined reading these two documents allow, which neither one gives you on its own.
From numbers to decisions
Reading these two documents is the first step; what actually adds value is understanding what they’re telling you about your specific business — that’s why we don’t just hand you your tax filings, we explain your balance sheet and P&L with judgement, not just deliver them.
