How profit and loss, balance sheet, and cash flow fit together

Three reports, three questions

The profit and loss account, often shortened to P&L, answers: What did the business earn and consume during this period? It groups revenue and expenses for a month, quarter, or year. The result is a profit or loss for that period.

The balance sheet answers: What is the business’s financial position on this date? One side contains assets such as bank balances, receivables, or equipment. The other contains liabilities and equity. It is a snapshot, not a list of all cash movements during the month.

Cash flow answers: Why did cash increase or decrease? A cash-flow view follows actual movements of money and commonly separates operating, investing, and financing activity. A small business may use a simpler cash analysis, but the core question is the same: where did liquidity come from and where did it go?

These descriptions are conceptual. The exact presentation and recognition rules depend on the business’s accounting basis and professional assessment.

A worked example: profitable, but waiting for cash

Consider a simplified consulting business. VAT, income tax, depreciation, and owner withdrawals are excluded so that timing stays visible.

At the start of April, the bank balance is €20,000. During April the business:

1. completes client work and issues an invoice for €12,000, payable in May;
2. pays €4,000 for current operating costs;
3. buys equipment for €2,400 in cash;
4. makes no loan payment and receives no owner financing.

The simplified April views are different:

The company can therefore show a positive operating result while its bank balance falls. The unpaid invoice supports profit and appears as a receivable, but it does not support April cash. The equipment purchase uses cash; its effect on profit depends on the applicable accounting treatment rather than simply equalling the payment.

The example is synthetic and intentionally simplified. It does not determine when a specific invoice, asset, or expense must be recognised. Ask the responsible accountant to confirm the accounting basis and treatment for the real case.

How the statements connect

The reports are not independent documents. The closing balance sheet carries the accumulated consequences of prior events. A receivable created by an invoice remains there until payment, correction, or another valid settlement resolves it. When the customer pays in May, cash rises and the receivable falls. That collection usually does not create the same revenue again.

The period result also affects equity, subject to the complete set of entries and closing process. Cash changes appear in balance-sheet cash and in the cash-flow explanation. A financing inflow, such as a new loan, can increase cash without increasing revenue; it also creates a liability. Repaying the loan principal can reduce cash and the liability without being the same as an operating expense.

Tracing both sides prevents two common mistakes:

• treating every bank credit as sales revenue;
• treating every bank debit as an expense of that period.

Both mistakes ignore the business event behind the payment.

Which monthly sources explain each difference?

DeinHans can prepare and connect the underlying documents, payments, payout components, open items and questions used for this bridge. It does not promise a three-statement forecasting model or determine recognition and presentation. The three reports remain professional outputs built from the reviewed bookkeeping record.

Four timing differences to look for

Invoice before payment

A sales invoice may belong to one period while the customer pays in the next. The open receivable explains the difference between reported revenue and cash received.

Payment before the expense period

An annual subscription or insurance payment can leave the bank at once while relating to several months. Whether and how it is allocated is an accounting decision, not a search shortcut.

Asset purchase

Equipment can consume cash immediately while its profit effect follows a different schedule. The invoice, payment, asset details, and professional classification should remain connected.

Financing or owner movement

Loan proceeds, loan principal repayments, capital contributions, and owner withdrawals affect cash, but they are not ordinary sales or supplier expenses. They need their own evidence and classification.

A practical review sequence

When the figures appear contradictory, do not start by changing a report. Start from the underlying events:

1. Confirm the reporting period and accounting basis used by the report.
2. Reconcile the opening and closing bank balances to the bank evidence.
3. List material unpaid sales invoices and supplier invoices at period end.
4. Separate operating payments from equipment, financing, tax, and owner movements.
5. Trace large or unusual items from document to entry to payment.
6. Ask the accountant about recognition, cut-off, depreciation, and tax treatment where judgement is required.

This sequence turns “the reports do not match” into specific timing and classification questions.

Who provides facts, prepares, and decides

DeinHans can help keep evidence, payments, questions, and prepared review context together. It does not make the three reports interchangeable and does not replace the accountant’s judgement about recognition, classification, or filing.

Questions to ask when one number looks wrong

• Is this report showing a period or a single date?
• Is it based on invoices, payments, or both?
• Which unpaid invoices explain the gap between revenue and cash?
• Did equipment, financing, tax, or owner movements change the bank balance?
• Are all bank accounts and payment channels included?
• Was the same transaction counted twice or left open after settlement?
• Which accounting judgement still needs professional review?

The goal is not to force the three headline numbers to match. It is to explain, with evidence, why they differ and how each difference is represented.
