How to read your P&L, balance sheet and trial balance
Most business owners open their financial statements, look at the bottom line, and close them again. The bottom line is the least useful thing in there. The real value is in how the three reports tie to each other — which is what makes a single suspicious number give itself away.
The Fatouraty team
Financial statements are not a school report to be read off the final grade. They are three answers to three separate questions, and their power is that they are all derived from the same data — so when one contradicts another, you are looking at an error rather than at two opinions. That last reading is the skill worth learning, and it needs no accounting background.
Three reports, three questions
| Report | The question it answers | Covers |
|---|---|---|
| Income statement | Did the business earn or lose? | A period: a month, a quarter, a year |
| Balance sheet | What does it own and owe, and what is the owners' share? | A single moment: one specific day |
| Trial balance | Is the ledger arithmetically consistent? | Every account up to a given date |
The difference between "a period" and "a moment" matters more than it looks. The income statement is a video: what happened between two dates. The balance sheet is a photograph: what the position was at that instant. Which is why "how much cash is on the income statement?" is a question with no answer — cash is a balance, and balances live on the balance sheet.
The income statement: did you earn?
It reads from top to bottom, each line subtracting something from the one above it:
- 1Revenue: what you sold during the period, regardless of collection.
- 2Cost of sales: the cost of what you sold specifically — not the cost of what you bought. Stock still on the shelf is not here; it is in inventory on the balance sheet.
- 3Gross profit: the difference. As a percentage of revenue it is your gross margin, and it is the most honest indicator of whether your pricing works.
- 4Operating expenses: salaries, rent, marketing and the like — what you pay to keep existing, whether you sold anything or not.
- 5Net profit: what is left. It is an accounting figure, not a bank balance, and those are two entirely different things.
The most informative line here is not net profit but gross margin as a percentage, because it moves slowly and exposes problems early. A margin sliding from 42% to 34% over three months says something specific — purchase costs rose, discounts widened, or the product mix shifted — long before any of it reaches the bottom line.
The balance sheet: what you own and owe, on one day
The balance sheet has two sides that are always equal: assets on one, liabilities and equity on the other. The equality is neither a coincidence nor an achievement; it follows necessarily from every transaction having been recorded on two equal sides from the start. The economic meaning is simple: everything you own came either from debt you owe or from the owners' money plus the profits the business has accumulated.
- Current assets: cash, bank, receivables, inventory — what converts to cash within a year.
- Non-current assets: equipment, vehicles, property, carried net of accumulated depreciation rather than at what you paid.
- Current liabilities: payables, tax due, and loan instalments falling due within a year.
- Equity: capital put in, plus retained earnings, less distributions taken out.
The first comparison worth making: current assets against current liabilities. If the second is larger, you are due to pay more within twelve months than converts to cash in the same window — a signal that arrives long before the problem does.
The trial balance: the report nobody shows investors
The trial balance is not a marketing report; it is a working one. It lists every account in your chart of accounts with its balance as a debit or a credit, and shows the two totals at the bottom. Its first job is that the two totals match. Its second — the more useful one in practice — is to make every account visible on one page, including accounts that do not appear separately on the other two statements.
This is where silent errors surface: a suspense account carrying a balance that should have been cleared, an expense account holding a negative figure, a tax account sitting as a debit when it should be a credit, or an account created by mistake and used exactly once. None of these breaks the balance or shows clearly on the income statement, and all of them are immediately visible on a trial balance to anyone reading it.
How the three tie together
This is the real skill, and it is only four relationships:
- Net profit for the period on the income statement raises retained earnings on the balance sheet by the same amount. A difference means an entry was posted straight to equity without passing through the result.
- The account balances on the trial balance are the source of both statements: income and expense accounts make the income statement; asset, liability and equity accounts make the balance sheet.
- Cash on the balance sheet must equal the closing figure on the cash flow statement, and the difference between the period's opening and closing must equal its net change.
- Receivables on the balance sheet must equal the total of the ageing report at the same date, and the same holds for payables.
When those four hold, a number that looks odd in one report can be chased to its source in the others. When they do not, you are not looking at performance but at a recording error. In Fatouraty every report is derived live from the same posted entries rather than stored as a precomputed copy, so there is no mechanism by which two reports could quote different figures because one of them was not refreshed.
The lines worth checking first
- 1Gross margin against the prior period, not against the plan. It is the slow slide that deserves attention.
- 2Current assets against current liabilities, to confirm the next twelve months are fundable.
- 3Receivables as a share of the month's sales: a share growing faster than sales means collection is slowing.
- 4Inventory as a share of cost of sales: growth without matching growth in selling means cash freezing on the shelves.
- 5Any account on the trial balance sitting in the wrong direction — a credit expense, a debit revenue — which is always a sign of an entry worth inspecting.
Frequently asked questions
What is the difference between the income statement and the balance sheet?
The income statement covers a period and says what happened between two dates; the balance sheet covers a moment and says what the position was on one specific day. The first is a video, the second a photograph — which is why balances like cash never appear on the first at all.
What is a trial balance for if I already have the other two statements?
Because it shows every account individually, including what the other two aggregate away or hide: suspense accounts, balances sitting in the wrong direction, accounts created by mistake. None of these breaks the balance or stands out on a summarised report.
Why doesn't net profit equal the increase in my bank balance?
Because profit is measured on accrual: sales not yet collected count towards it, stock bought but unsold does not, and loan principal and asset purchases are cash out that never appears as an expense. The whole difference is explained by those items.
What is gross margin and how do I calculate it?
Gross profit divided by revenue, where gross profit is revenue less the cost of what you actually sold. It is the best early indicator of whether pricing works, because it moves slowly — so a decline shows there before it reaches net profit.
Do my statements need an external audit?
It depends on your country, size and legal form, and the rules differ across the region and get updated. What is certain is that statements derived from a double-entry ledger with a complete audit trail are what makes an audit possible and quick when one is required.
How often should I look at these reports?
Monthly, after the month is closed, and against the prior month rather than an absolute figure. Annual review alone reveals trends a full year after they started — far too long to correct pricing or collection.
