Illustrative worked example
One month-end close: what goes in, and what the founder gets back.
A finished close hands the owner six things: a dated statement that the month is closed, management accounts on reconciled figures, the reconciliations behind them, the receivables position with a next action per invoice, the payables prepared for the owner to release, and a written list of what is still unresolved and why. Everything below is the work that produces those six.

March, as it actually arrives.
A close is not a single event at the end of a month; it is the last four days of a process that ran for thirty. Harbour Line Studio has fourteen people, twenty-three invoices issued in March, thirty-one supplier bills, two bank accounts and one company card. Roughly a hundred and forty transactions in total — a small business by any measure, and still too much to reconstruct from memory in April.
| What lands | When | What is done with it, on the day |
|---|---|---|
| Bank and card transactions | Daily, two accounts and one card | Matched to an invoice, a bill or a known category. Anything that will not match is raised as a question rather than posted to a holding account. |
| Sales invoices — 23 in March, $186,400 | On delivery milestones, mostly mid and end month | Recorded when issued, with the engagement it belongs to and the terms it carries. |
| Supplier bills — 31 in March | Continuously | Entered on receipt, whether or not payment is due yet, so cost lands in the month the work did. |
| Card and expense receipts | Continuously, from six people | Attached to the transaction they support. A receipt that has not arrived within the week is chased while anyone still remembers the spend. |
| Payroll — run on the 25th | Monthly | Posted from the payroll report, then agreed to what actually left the bank the same week. |
| Customer receipts — 17 in March | Continuously | Matched to the specific invoices they settle. Where a payment covers several, the split is recorded rather than assumed. |
Nothing in that table waits for the month to end. That is the entire reason the close below takes four working days.
The last day, and the four working days after it.
Cut-off is the decision about which month a transaction belongs to. It is settled by the date the work happened or the goods arrived, not by the date an invoice was raised or a payment cleared — which is why the four days after the month end exist at all.
- Day one — the bank. Feeds pulled through to 31 March and every account agreed to its statement. Closing balances tie on all three. Two lines will not match and are listed rather than forced.
- Day two — the two ledgers. Every March invoice confirmed present; every supplier bill for March work entered, including two that arrived on 2 April for work delivered in March. One cost was delivered and not yet billed at all, so it is accrued. Receipts matched to invoices; one receipt cannot be split with confidence and is held.
- Day three — payroll and evidence. The March run posted and agreed to the bank: net pay $104,900 out on the 25th, employer costs recorded, deductions agreed to the payroll report. Then the evidence sweep — every entry above the studio’s $100 threshold checked for its document. One is missing.
- Day four — unusual items, exceptions, close. Entries outside the normal pattern reviewed: a $9,400 equipment purchase and a client’s query on part of an invoice. The four unresolved items consolidated onto one list. Figures frozen, the close dated 4 April, and the pack produced from the frozen figures.
What did not resolve, and why that is written down.
Four items were still open when March closed. None of them stopped the close, and none of them was hidden inside a figure. This list is the part of a close that most reporting leaves out, and it is the part an owner actually needs.
| What is open | Why it is open | Who holds it | Effect on March |
|---|---|---|---|
| A receipt of $12,600 with no remittance advice, against three invoices of $5,400, $4,200 and $3,000 | The customer paid a round sum and did not say which invoices it covers. Guessing the split would make three invoice balances wrong to make one bank line right. | At Par — allocation query sent 2 April | Cash and total receivables are correct. The detail behind one customer’s balance is provisional until the split is confirmed. |
| Freelance illustration delivered in March, no supplier invoice yet | The supplier bills in arrears. The work is done and the rate is agreed, so the cost belongs to March. | At Par — accrued at $3,150, marked as an estimate | Cost is in the right month. The figure may move by a small amount when the invoice arrives; the movement will be visible as a correction. |
| A $980 card payment to a software vendor with no receipt | The invoice was never emailed. The statement line proves the payment but not what was bought. | Harbour Line — requested from the vendor 3 April | The amount and the account are right. The evidence is incomplete and is listed as such rather than assumed complete. |
| A client query on $6,800 of a $14,200 invoice | The client says one line was outside the agreed scope. The delivery is not in question; the scope of one item is. | The founder — commercial decision | The invoice stays in receivables, marked as queried with the reason, and is not chased as a simple late payment. |
The last row is the important one. Whether to concede $6,800 is not an accounting question and no provider should answer it. What a close owes the founder is the fact, the amount, the reason and the evidence — so the decision is made deliberately rather than by an invoice quietly ageing.
What landed in the founder’s hands on 4 April.
One email, six attachments, and nothing requiring a request. The figures below are the frozen ones — the same numbers that sit behind every statement in the pack.
- A close statement, one page. March is closed as at 4 April, closed by a named person, with the four open items listed and no others.
- Management accounts. March profit and loss against February and against the year to date, a balance sheet at 31 March, and a cash summary. Revenue $186,400; payroll and employer costs the largest single line.
- The reconciliations. Two bank accounts and the company card, each agreed to statement, with the two reconciling items named on the face of it.
- The receivables position. $214,700 outstanding across nineteen invoices, each carrying a state, an owner and a next action with a date. Two customers have given payment dates; both are recorded. One invoice is marked as queried, not as late.
- Payables prepared for release. Eleven bills, $47,900, with due dates, ready for the founder to authorise and pay. Nothing was paid. Preparing a payment run and releasing money are two different acts, and only one of them belongs to a finance provider.
- The evidence. Every entry above the threshold linked to the document that supports it, retrievable by someone who did not do the bookkeeping — with the one missing receipt named rather than glossed over.
And three decisions, put in front of the founder rather than left in the ledger: whether to concede the queried $6,800; which of the eleven prepared payments to release and when; and whether to reopen the retainer with a client whose delivered hours in March ran well past what the retainer covers. All three are commercial. None of them is a provider’s to make.
Four days, because nothing was reconstructed.
In this illustration the close took four working days. That is a consequence of how March was run, not of how fast anyone worked in April. Every one of the four days spent its time on judgement — cut-off, evidence, unusual items, exceptions — because none of it was spent on discovery.
- Transactions were recorded as they happened, so day one started from a complete population rather than a pile.
- Evidence arrived with the transaction, while somebody still knew what it was for. Chasing a receipt in week one costs a message; chasing it in April costs a conversation.
- The four open items were known before the close began. None of them was a surprise found on day four.
- Payroll was agreed to the bank on 26 March, not on 4 April.
- Nothing was posted to a holding account to make a total agree, so no day was spent unpicking last month’s convenient entries.
The opposite pattern — a month recorded in a single sitting after it ends — is a different exercise with a different cost, and it is the subject of catch-up bookkeeping rather than of a close. To test where your own month sits before you get there, the month-end readiness checklist runs the same nine areas this close ran.
Where At Par fits — and the limits.
The sequence above is the job At Par does every month for owner-led service businesses. Books kept current through the month, cut-off settled deliberately, accounts reconciled, evidence attached, exceptions surfaced with a reason and an owner, and the period closed on a date — with a qualified accountant (ACCA) accountable for the work. That is bookkeeping and month-end close, and the pack that follows it is management accounts and reporting. The receivables state described above is receivables and invoice follow-up.
The figures, the studio and the four exceptions on this page are invented to make the sequence legible. The sequence itself is not.
Asked after reading a worked close.
Is this month-end worked example based on a real client? +
No. Harbour Line Studio is a fictional company invented for this page, and every figure, invoice, exception and date is invented with it. It is an illustrative worked example, not a customer case study, and nothing in it describes the accounts of any real business. Its purpose is to make the shape of a close legible — what arrives, what is decided at cut-off, what stays open and why, and what the owner receives at the end.
What is cut-off in accounting, and why does it decide which month a cost belongs to? +
Cut-off is the rule that a transaction belongs to the period in which the work happened or the goods arrived, not the period in which the invoice was raised or the payment cleared. A supplier bill arriving on 2 April for work delivered in March is a March cost. Without a cut-off discipline, costs drift into whichever month their paperwork happens to land in, and two consecutive months become impossible to compare.
What is an accrual, and when does a month-end close need one? +
An accrual records a cost that has been incurred but not yet billed, so the expense sits in the month the work was done. It is needed whenever a supplier bills in arrears, a subcontractor has delivered but not invoiced, or a service has been consumed and the invoice runs on a different cycle. An accrual should carry the basis it was calculated on, and be visibly marked as an estimate so the later correction is expected rather than surprising.
Why do the same few exceptions come back at every month end? +
Because most exceptions are symptoms of a routine that has not been fixed. Unallocated receipts recur when customers pay in round sums and nobody asks for a remittance advice. Missing receipts recur when expense capture depends on memory. Late supplier bills recur when a supplier bills in arrears and nobody set up an accrual. Treating each one as a one-off problem means solving it twelve times a year; treating the cause means solving it once.
How much of a business owner’s time should a month-end close take? +
The preparation should take none of it, and the decisions should take some. In the example above the owner is asked for three things: whether to concede a queried invoice line, which prepared payments to release, and whether to renegotiate a retainer. Those are commercial judgements only the owner can make. If a close routinely requires the owner to explain transactions or find documents, the problem is upstream of the close, not in it.
Does closing a month faster mean closing it less thoroughly? +
Not necessarily, and the two are usually confused. Speed at close comes from what happened during the month — transactions recorded as they occurred, evidence attached on the day, exceptions raised when they appeared. A close that is fast because it skipped reconciliation or buried unresolved items is not fast, it is unfinished. The honest test is not the number of days but whether the closing date is predictable and what the unresolved list says.
