4.1Finance for managers (balance sheet, P&L)
The essentials in 30 seconds
- Balance sheet = snapshot of assets at one point in time (what we own / what we owe).
- Profit-and-loss (P&L) = film of activity over a period (income − expenses = profit).
- Reflex: never confuse accounting profit with cash — we pay salaries with cash.
Running mini-case — Salim reads the balance sheet with the accountant
Salim must request a training budget for his 4-person team. Management answers "look at the figures". He books time with the accountant: together, they read the balance sheet (what does the company own? what does it owe?) then the P&L (does the activity really pay?). We will follow his reading, step by step.
This same case returns in the course, the diagram, the script and the 48h challenge.
1. Two key statements
A manager does not need to be an accountant, but understanding financial fundamentals is essential to discuss, decide and steer. Two key statements: the balance sheet (a snapshot of assets at one point in time: what the company owns and owes) and the profit-and-loss statement (a film of activity over a period: income, expenses, and the resulting profit).
Analogy: the balance sheet is the finish-line photo of a race (the position at one instant), the P&L is the film of the race (how we got there). Salim starts with the photo with the accountant, then watches the film of the year.
2. Profit, margin, profitability
From these statements come essential concepts: profit (gain or loss), margin (what remains after certain costs) and profitability (the ratio between what we earn and what we commit).
Reading these indicators helps understand the health of the company, justify requests and measure the economic impact of decisions. Finance is not for experts only: it is the common language of performance. Salim thus puts figures on his training request against the margin earned.
🔎 Concrete example — Profit vs cash (Salim's case)
Profit: accounting (income - expenses, includes depreciation).
Cash: money actually available.
→ we pay salaries with cash, not with profit.Result: Salim watches both dimensions before defending his budget.
Lesson: connect decisions to their economic impact.
Section vocabulary reinforced definitions
- Balance sheet
- Snapshot of assets at one point in time: assets (what we own) and liabilities (what we owe / equity).
Simple example: on 31 December: computers and customer receivables on one side, supplier debts and loan on the other.
What it is not: the film of the year (that is the role of the P&L).
Reflex: always check the snapshot date before interpreting.
- Profit-and-loss statement
- Film of activity over a period: income − expenses = profit (gain or loss).
Simple example: sales of the year minus salaries, rent, purchases = gain or loss.
What it is not: the bank account balance.
Reflex: read income, expenses, then profit, in that order.
- Profit
- Difference between income and expenses: gain (positive) or loss (negative) over the period.
Simple example: income 100 − expenses 90 = gain of 10.
What it is not: available cash.
Reflex: ask "and what does cash say?".
- Margin
- What remains from sales after deducting certain costs (gross margin, trading margin...).
Simple example: sales minus cost of sales = what remains to cover the rest.
What it is not: the final profit (other expenses remain).
Reflex: always clarify "margin on what" before comparing.
- Profitability
- Ratio between what we earn and what we committed: measures economic efficiency.
Simple example: for 100 committed, 10 earned = 10% profitability.
What it is not: an amount in euros (it is a ratio).
Reflex: compare with the previous period, not in absolute terms.
In practice — Reading basic financial statements
- Get a simplified balance sheet: tell apart assets (what we own) and liabilities (debts + equity).
- Read a P&L: identify income (sales), expenses, and the resulting profit.
- Calculate a simple margin (sales − cost of sales) and interpret: what remains to cover the rest?
- Connect to your decisions: how do your choices (spending, projects) impact profit and profitability?
Ready-to-say script — asking the accountant for a first walkthrough (2 min)
"I am preparing a budget request and I want to understand our figures. Could you show me the latest simplified balance sheet and P&L? I would like to spot: what we own and owe, then whether activity earns a margin. I am not after technical detail, just enough to decide seriously."
Say it simply: no accountant refuses to explain to a manager who wants to decide with figures (and it is faster than you think).
Copy-paste template — first financial reading sheet
READING SHEET — BALANCE SHEET + P&L
BALANCE SHEET (snapshot on [date]):
- Assets: what we own: [e.g. equipment, customer receivables]
- Liabilities: what we owe: [e.g. supplier debts, loan]
P&L (period: [e.g. year]):
- Income: [e.g. sales]
- Expenses: [e.g. salaries, rent, purchases]
- Profit: gain / loss of [amount]
CASH QUESTION: does available cash track profit? [yes / no, why]
MY REQUEST: [e.g. training budget] — estimated impact: [amount] vs margin: [reading]Micro-business (2-3 people)
Ask the accountant for a one-page simplified balance sheet. Track each quarter: profit + cash, nothing more.

Account for real payment delays (public/private): a profit with late receivables still means tight cash.

Accounting terms translate poorly word for word: validate each concept with a local figures example.
✓ Best practices
- Tell balance sheet (assets) apart from P&L (activity).
- Never confuse profit with cash.
- Connect your decisions to their impact on profit.
✗ Common pitfalls
- Confusing accounting profit with available cash.
- Believing finance is for experts only.
- Deciding without measuring economic impact.
Key takeaways
- The balance sheet = snapshot of assets (assets/liabilities) at one point in time.
- The P&L = film of activity (income − expenses = profit).
- Key concepts: profit, margin, profitability.
- Finance is the common language of performance, not an experts-only field.

Frequently asked questions
What is the difference between balance sheet and P&L?
The balance sheet is a snapshot at one precise instant: it shows what the company owns (assets) and what it owes (liabilities). The P&L is a film over a period: it summarizes income and expenses leading to profit. One shows position (assets), the other performance (activity): they complement each other.
Profit and cash, is it the same thing?
No, and confusing them is dangerous: profit is accounting (including non-cash items such as depreciation), cash is money actually available. A profitable company can run short of cash if customers pay late. We do not pay salaries with accounting profit, but with cash.
Are accounting rules the same everywhere (may vary by country)?
No: balance-sheet presentation, depreciation, tax rules and legal deadlines may vary by country. The examples in this section are simplified and for illustration only. Before any decision (investment, budget request), get figures validated by your local accountant.
Salim reads the accounts with the accountant: profit of 10, but customers pay at 90 days and cash is almost empty. He must pay salaries Friday. What must he understand?
