Month-End Close Checklist for Small Business: A 5-Day Routine

A month-end close is the routine that turns a month of transactions into numbers you can trust. A Hong Kong SME can do it in five working days. On days 1–2, reconcile every bank, FPS and card account and enforce sales and purchase cut-off. On day 3, post accruals, prepayments and payroll, including MPF due by the 10th. On day 4, count or roll forward inventory and revalue foreign-currency balances. On day 5, review, lock the period and send a one-page management pack.

Why a five-day close is the right target

Numbers that arrive six weeks late describe a business that no longer exists. By the time a slow close shows a margin problem, you have already repeated it for another month.

Five working days is achievable for a company with a few bank accounts, one entity and a part-time or single in-house accountant. It is fast enough for the numbers to steer decisions, and slow enough to catch late supplier invoices and bank lines.

The larger benefit arrives at year end. A company that closes properly twelve times hands its auditor a trial balance that already ties to bank statements and ageing reports. Our guide to why small companies still need an audit explains why that matters even for the smallest private company.

The five-day checklist at a glance

Adapt the days to your business, but keep the order. Reconciliations come first, because every later step depends on cash being right.

Days 1–2: cash, cut-off and the ledgers

Reconcile bank, FPS and card accounts

Reconcile every account the company holds, not just the main current account. That includes foreign-currency accounts, deposit accounts, the petty-cash float and payment-platform balances.

FPS receipts deserve care. Customers often pay without the invoice reference, or pay two invoices in one transfer, so match on amount, date and payer name, and record any payment you cannot allocate as "unapplied cash" rather than guessing. Our guide to invoicing for FPS and PayMe covers how to put the reference on the invoice so fewer payments arrive unmarked.

Card and payment-gateway settlements usually arrive net of fees. Book the gross sale, the fee as an expense and the net amount to the bank. Posting the net figure understates both revenue and costs.

A reconciliation is finished when the reconciled balance equals the statement balance and every reconciling item has an explanation and an expected clearing date. An uncleared cheque from four months ago is not a reconciling item. It needs to be investigated.

Enforce cut-off

Cut-off means recording income and costs in the month they belong to, not the month the paperwork arrives.

• Sales: goods shipped or services delivered by the last day of the month are invoiced in that month. Delivered but unbilled work is recorded as accrued income.
• Purchases: goods received or services consumed are recorded as costs even if the supplier has not yet invoiced. Match delivery notes against purchase orders to find them.
• Receipts in transit: a customer payment dated 31 March that clears on 2 April belongs in April's bank balance. List it as a reconciling item rather than moving it.

Review AR and AP

Run the aged debtors and aged creditors reports and agree each total to the control account in the trial balance. A difference means a posting went straight to the control account and skipped the sub-ledger. Fix it now, because it will be harder to find at year end.

Then read the ageing properly. Anything over 60 days should have a named action. The accounts receivable playbook sets out a reminder cadence. If a debt is genuinely doubtful, decide on a provision instead of carrying it at face value.

Day 3: accruals, prepayments and payroll

Accruals and prepayments make the profit and loss account reflect the month's real activity. They are also where most small-company accounts go wrong.

Worked example: an accrual and its reversal

Your IT consultant finished HK$36,000 of work in March. Their invoice arrives on 12 April.

31 March (accrual):

• Debit IT consultancy expense HK$36,000
• Credit accrued expenses HK$36,000

March's profit and loss account now carries the cost of work done in March.

1 April (automatic reversal):

• Debit accrued expenses HK$36,000
• Credit IT consultancy expense HK$36,000

12 April (invoice posted as normal):

• Debit IT consultancy expense HK$36,000
• Credit accounts payable HK$36,000

April's net charge is HK$36,000 − HK$36,000 = HK$0. The cost appears once, in March, where it belongs.

If the invoice comes in at HK$38,500, April carries the HK$2,500 difference. That is small enough to leave in April rather than reopen March.

Worked example: a prepayment

The company pays an annual office insurance premium of HK$24,000 on 1 January for cover from 1 January to 31 December.

• Monthly charge: HK$24,000 ÷ 12 = HK$2,000
• At 31 March, 3 months have been used: 3 × HK$2,000 = HK$6,000 expensed
• Prepayment on the balance sheet: HK$24,000 − HK$6,000 = HK$18,000

Keep a prepayment schedule listing each item, its start and end dates, and its monthly release, so day 3 is a single journal rather than a hunt.

Payroll and MPF

Post the month's payroll journal, including employer MPF and any bonus or leave-pay accruals.

MPF mandatory contributions are 5% from the employer and 5% from the employee, calculated on relevant income. The minimum relevant income is HK$7,100 a month and the maximum is HK$30,000, so the mandatory employer contribution for a monthly-paid employee is capped at HK$1,500. An employee earning less than HK$7,100 does not contribute, but the employer still pays its 5%.

The MPFA's contribution-day guidance says contributions for monthly-paid employees must reach the trustee on or before the 10th of the following month. Late payment triggers a 5% surcharge on the default amount, paid to the employee's account. The MPFA's employer FAQ covers the details. Remittance now runs through the eMPF Platform; see our eMPF employer checklist.

Where JetFlow fits: JetFlow's payroll calculates MPF alongside the pay run, receipts dropped into its AI Hot Folder are read and routed into the books, and the finance module keeps AR and AP ageing next to the ledger. See how JetFlow handles the month-end close.

Day 4: inventory and foreign currency

Inventory

If you hold stock, the balance sheet figure needs support. Full counts every month are unrealistic for most SMEs, so a practical pattern is:

1. Roll forward the perpetual record: opening stock plus purchases less cost of sales.
2. Cycle-count a rotating sample each month, prioritising high-value and fast-moving lines.
3. Investigate any difference between counted and recorded quantities before adjusting.
4. Review for obsolescence. Under SME-FRS, inventories are carried at the lower of cost and net realisable value, so slow-moving or damaged stock may need writing down.

Foreign-currency revaluation

Monetary balances held in foreign currency, such as bank accounts, receivables and payables, are retranslated at the closing rate each month-end. The difference is an unrealised exchange gain or loss.

Worked example. A customer owes EUR 10,000, booked when the rate was HK$8.50 per euro, so HK$85,000. At month-end the rate is HK$8.62.

• Revalued balance: EUR 10,000 × 8.62 = HK$86,200
• Unrealised gain: HK$86,200 − HK$85,000 = HK$1,200

Post HK$1,200 as a debit to the receivable and a credit to exchange gains. The rates here are illustrative, so use the rate from a consistent, documented source each month.

US dollar balances move far less. Under the HKMA's Linked Exchange Rate System, the Hong Kong dollar trades within HK$7.75–7.85 per US dollar. A US$100,000 balance can therefore move by no more than about HK$10,000 across the whole band. Renminbi, euro, yen and sterling balances can swing much further, so do not skip them.

Day 5: review, lock and report

Review the trial balance

Before you lock the month, run these checks.

• Compare each profit and loss line with last month and with budget. Investigate anything that moved by more than a threshold you set, for example 10% and HK$20,000.
• Check the balance sheet for items that should be zero: suspense, unallocated cash and payroll clearing accounts.
• Confirm the bank balances in the trial balance equal the reconciled statement balances.

Lock the period

Lock the month in your accounting system once the review is complete, so nobody can post into it. Late items go into the current month with a note. A period that stays open is a period that changes after you have reported on it.

The management pack

One page is enough for most owners. Include:

Worked example: debtor days. Trade receivables are HK$1,200,000 at 31 March and March revenue is HK$800,000. DSO = HK$1,200,000 ÷ HK$800,000 × 31 = 46.5 days. If your terms are 30 days, customers are paying about two weeks late on average.

Common mistakes

• Posting the net card settlement. Revenue and merchant fees both disappear from the profit and loss account.
• Accruing without reversing. The cost is booked twice: once as an accrual, again when the invoice arrives.
• Letting reconciliations lag. A three-month-old unreconciled bank account is not a month-end problem any more. It is an investigation.
• Revaluing only the US dollar account. The peg keeps USD movements small. The real exposure is usually in other currencies.
• Missing the MPF 10th because payroll closed late. The contribution day does not move to suit the close. Schedule payroll so the remittance is ready by then.
• Leaving the period open. Someone will post into it, and last month's pack will no longer agree to the books.
• Throwing away the support. Section 51C of the Inland Revenue Ordinance requires business records to be kept for at least seven years. The IRD's record-keeping guidance sets out what that covers.

Frequently asked questions

How long should a month-end close take for a small business?

Five working days is a realistic target for a single-entity SME with a handful of bank accounts. Businesses with inventory, several currencies or group companies may need longer at first, but should aim to shorten it every quarter.

What is included in a month-end close checklist?

Bank and payment reconciliations, sales and purchase cut-off, AR and AP ageing reviews, and accruals and prepayments. It also covers depreciation, payroll and MPF, inventory, foreign-currency revaluation, a trial balance review, a period lock and a management report.

Do I need to revalue foreign-currency balances every month?

For management accounts, monthly revaluation keeps the profit and loss account honest and avoids a single large adjustment at year end. At minimum, monetary foreign-currency items must be translated at the closing rate in the year-end financial statements.

What is the difference between an accrual and a prepayment?

An accrual records a cost you have incurred but not yet been invoiced for, and is a liability. A prepayment records a cost you have paid in advance for a future period, and is an asset released to the profit and loss account as the period passes.

When is the MPF contribution day in Hong Kong?

For monthly-paid employees, contributions must reach the MPF trustee on or before the 10th day of the following month. A 5% surcharge applies to late contributions and is paid to the employee's account.

Key takeaways

• Close in five working days: cash on days 1–2, journals on day 3, inventory and FX on day 4, review and lock on day 5.
• Reconcile every account, including FPS, card settlements and foreign-currency accounts, and book card fees gross.
• Set accruals to reverse automatically, and keep a prepayment schedule so day 3 is mechanical.
• Have MPF ready before the 10th: 5% plus 5% on relevant income between HK$7,100 and HK$30,000.
• Lock the period, then send a one-page pack built on margin, cash runway and debtor days.

A fast close is mostly a matter of having bank lines, receipts and payroll in the same place as the ledger. Start free with JetFlow and run your next month-end from reconciliation to period lock in one system.
