A profit and loss report shows income and expenses over a period, leading to a profit or loss. It helps explain how trading performed. It does not tell you how much cash is available today or automatically establish the business’s tax bill.

Before reading the numbers, check the report dates, business entity and accounting basis. A full year, a single month and a year-to-date report answer different questions. If some records are missing, ask which figures are provisional before drawing conclusions.
Read from sales towards the result
Revenue usually appears near the top. Check what is included: sales returns, credits and different income streams can affect the number. Compare like periods, and ask whether the report treats VAT consistently where relevant.
Next come costs directly associated with delivering the sales, followed by gross profit. Operating expenses then show the broader costs of running the business. Finance costs, tax and other items may appear further down depending on the report’s layout.
Labels vary between systems. Ask what “net profit” means in your pack: before or after tax, before or after interest, and whether unusual items are included. A label alone is not enough to compare two reports.
Walk through a simple report
Illustrative example: a service business reports these figures for one month. They are invented, exclude VAT and omit tax and other complexities.
| Line | Amount | What to ask |
|---|---|---|
| Revenue | £40,000 | Which services and customers generated it? |
| Direct delivery costs | £16,000 | Which jobs required these resources? |
| Gross profit | £24,000 | Is the work covering delivery costs consistently? |
| Operating expenses | £18,000 | What changed in the wider running costs? |
| Operating profit | £6,000 | Does this reflect normal trading? |
| Finance costs | £500 | What borrowing or charges produced this? |
| Profit before tax | £5,500 | What further tax assessment is needed? |
The report is useful because each layer answers a different question. Weak gross profit suggests reviewing delivery economics. Strong gross profit with weak operating profit suggests looking at overheads. Neither diagnosis should be based on one unexplained total.
Compare the right things
Add a budget comparison and a comparable previous period. For seasonal businesses, the same month last year may be more informative than the immediately preceding month. Also consider changes in trading days and the size of the team.
Look for both money changes and explanations. Higher wages could reflect extra productive staff, overtime, a payroll error or a cost reclassification. A lower marketing cost might represent a saving, a delayed invoice or cancelled activity that will affect future sales.
Separate recurring movements from unusual events. A one-off insurance settlement or equipment disposal should not be mistaken for stronger customer demand. Request a short commentary explaining the largest differences.
Remember costs can belong to a different cash date
Accounts prepared on an accrual basis can include costs incurred before payment and spread suitable advance payments across their coverage period. Equipment may appear through depreciation rather than as a full operating expense at purchase.
That is why a profitable month does not necessarily produce an equivalent rise in the bank. Customer invoices can remain unpaid, equipment can consume cash and borrowing repayments can reduce the bank without appearing as one undivided expense.
Ask the accountant for a bridge between profit and cash where the difference is substantial. It is more useful than assuming either the report or the bank must be wrong.
Investigate before reacting
If a line looks surprising, open the supporting transactions. Check duplicates, missing invoices, unusual descriptions and entries posted to a different category. Compare the report with reconciled bookkeeping rather than using an unreviewed live dashboard as final evidence.
Do not cut spending merely because it is the largest line. Identify the purpose and effect. Removing a delivery resource might damage sales, while negotiating an unused subscription could improve profit without changing customer service.
Similarly, rising revenue is not proof that every job is worthwhile. Ask for service, customer or project detail when the total conceals different margins.
Finish with a short action list
Choose a few questions from the report: which revenue stream is growing, which direct cost is drifting and which overhead needs explanation? Assign an owner and follow-up date to each. Review the answers in the next pack.
