The profit and loss report looked believable.
Revenue was close to management's expectations. Wages looked reasonable. Software costs were not obviously strange. Nothing about the headline profit number demanded an immediate investigation.
Then the balance sheet was reviewed.
In this illustrative case study, an 18-person consultancy generates approximately $3.1 million in annual revenue. Management uses monthly reports to make hiring and pricing decisions, so “plausible” is not a sufficient reporting standard.
Four balances changed the level of confidence the founder could place in the P&L.
Why the balance sheet tests the P&L
Most founders naturally start with the profit and loss statement. It answers intuitive questions: what did we sell, what did staff cost and did we make a profit?
The balance sheet contains cash, receivables, payables, loans, taxes, payroll liabilities, fixed assets and equity. Those accounts can feel removed from day-to-day operations, but they often reveal whether the P&L is supported by real transactions and obligations.
If a cost has been parked on the balance sheet, profit may be overstated. If a liability has been incorrectly expensed, profit may be understated. If customer receipts have not been allocated, receivables can be wrong. If a twelve-month cost is recorded in one month, monthly performance can be distorted.
The two statements are connected.
Four balances that needed attention
$54,300 of receivables was more than 90 days old
The aged receivables report included $54,300 outstanding beyond 90 days. Within that amount, $9,200 had already been paid but not allocated, $4,500 related to an unresolved credit and $3,000 was no longer expected to be collected.
That meant $16,700 of the old balance did not represent ordinary late-paying customers.
Until those items were corrected, the balance sheet overstated expected collections and the founder's cash forecast started from the wrong position.
The loan balance was overstated by $31,200
The business had made regular repayments, but the Xero liability had not moved consistently with the lender statement.
Some payments were recorded entirely as finance expense. Others had been allocated through a general loan-payment account without a supporting reconciliation.
The result was a $31,200 difference between the accounting file and external evidence. The liability was wrong, and the historic expense treatment needed to be understood before the P&L could be relied on.
A $14,600 payroll liability could not be explained
Payroll operated normally, but a liability balance had accumulated over several months.
Part related to timing between a payroll run and payment. The remainder required transaction-by-transaction investigation.
The key problem was not that the account contained a balance. Payroll liabilities often should. The problem was that nobody could explain what the total represented or when it should clear.
A $24,000 insurance payment sat entirely in one month
The annual insurance premium supported the business for twelve months but had been recorded as a single month's expense.
For statutory or tax purposes, the appropriate treatment depends on the facts and applicable requirements. For monthly management reporting, the founder needed to understand that the expense spike was largely a timing effect rather than a sudden deterioration in operating performance.
Plausible totals can still tell the wrong monthly story.
Why believable reports can be dangerous
Accounting errors do not need to make a report look absurd.
If monthly software normally costs $15,000, an extra $1,200 coded incorrectly still looks believable. If contractors move between cost of sales and overheads, total profit may remain unchanged while gross margin becomes less meaningful. If an annual cost lands in one period, the spike can be mistaken for weak performance.
Plausibility is not verification.
The more a business relies on monthly accounts to hire, price work or manage cash, the more important it becomes to understand the process that produced those accounts.
The balance sheet forces harder questions
Cash
Does the ledger agree with the bank and card statements?
Accounts receivable
Does the balance represent money customers genuinely owe? Have payments, credits and write-offs been processed?
Accounts payable
Does the business still owe every old supplier bill? Are payments and duplicate bills reflected correctly?
GST, payroll and superannuation
Do the liability balances connect to the underlying returns, payroll records and subsequent payments?
Loans
Does the balance agree with the lender? Have principal and interest been separated appropriately?
Prepayments and accruals
Are material income and expenses appearing in the period where management expects to assess performance?
Clearing accounts
What sits in them, why is it still there and who owns the next step?
That final set of questions is deceptively powerful. A temporary account should not become a permanent mystery.
Why this matters before the decision
Assume the founder believes the consultancy produced enough margin to hire two people. Months later, receivables are written down, expenses are corrected and an unrecorded obligation is recognised.
The accounting correction did not create the economic problem. It revealed a condition that already existed when the hiring decision was made.
Reliable books matter before the decision, not six months afterwards.
When a month should be considered closed
For a service business of this size, a close might include:
- bank and credit-card reconciliation;
- receivables and payables review;
- payroll-related liability checks;
- GST and control-account review;
- loan reconciliation;
- review of material balance-sheet accounts;
- accruals and prepayments where they affect decisions;
- investigation of old or unusual balances;
- comparison with prior periods or expectations; and
- documented sign-off on outstanding exceptions.
The process should match the complexity of the business. The principle is consistent: reports should be the output of review, not a substitute for it.
Check your own balance sheet
For every material line, ask: what specifically makes up this number?
You should be able to move from the balance to evidence:
- bank balance → bank statement;
- receivables → customer invoices and payment records;
- payables → supplier bills and payments;
- loan → lender statement;
- payroll liability → payroll and payment records;
- fixed assets → asset register and purchase records.
Flag material accounts that cannot be connected to evidence, old clearing balances, loans that do not move despite repayments, liabilities that keep growing and accounts nobody can confidently explain.
These are prompts for investigation, not automatic proof of error.
