A Singapore SME can close its books on a fixed five-day sequence: day 1 cut-off and bank, day 2 sales, day 3 purchases and payroll, day 4 accruals and adjustments, day 5 review and lock. The sequence matters more than speed. Each day produces a defined output that the next day depends on. This checklist gives the tasks, owners and outputs for each day, a template you can copy, and the steps an agent can take over without taking over the decisions.
What is a monthly close?
A monthly close is the routine that turns a month of transactions into reliable management accounts. You confirm that every bank line, sale and bill is recorded, that period-end adjustments are made, and that nobody can change the month afterwards.
Why it matters for a small company:
- Cash decisions depend on knowing what is owed and what is due.
- GST returns, payroll filings and year-end accounts are easier when every month is clean.
- Errors found in week one cost minutes. Errors found at year-end cost days.
We assume a company with a small finance team, one or two bank accounts, GST registration, and accounting software such as Xero. Adjust the days to your size.
Day 1: cut-off and bank
Goal: the bank and card records are complete and the month is cut off.
- [ ] Download or confirm bank and card statements to the last day of the month.
- [ ] Confirm the bank feed has loaded every line, or import the missing ones.
- [ ] Reconcile each bank and card account to the statement closing balance.
- [ ] List unmatched items and assign each to an owner.
- [ ] Capture the cash and foreign-currency balances in their own currency.
Output: every bank account reconciled, or a list of named exceptions with owners.
An agent can pull statements, match lines to open invoices and bills by amount, date and reference, and queue the rest. See automated bank reconciliation in Singapore and how it compares to bank feeds. A person approves the matches that fall outside the stated tolerance.
Day 2: sales and receivables
Goal: every sale is invoiced in the right month, and receivables are accurate.
- [ ] Confirm all deliveries, completed services and milestones are invoiced.
- [ ] Check invoice numbering for gaps and duplicates.
- [ ] Apply customer payments, including partial payments and credit notes.
- [ ] Review the ageing report. Mark invoices over your threshold for follow-up.
- [ ] Review GST codes on sales: standard-rated, zero-rated, exempt, out of scope.
Output: a receivables ageing that ties to the ledger, and a chase list.
An agent can compare delivery or timesheet records to the invoice list and flag what is missing. It can draft chase messages from your schedule. The send waits for a named person. In KYN's own books, receivables are chased at 3, 14 and 30 days.
Day 3: purchases and payroll
Goal: every bill and claim is recorded, and payroll is posted.
- [ ] Enter all supplier bills received up to the cut-off, including those dated in the month but received late.
- [ ] Check for duplicates by supplier, number and amount.
- [ ] Process staff expense claims with receipts attached.
- [ ] Post payroll, employer CPF and related payments.
- [ ] Review GST on purchases: valid tax invoice, correct code, correct period. See GST on software and AI subscriptions.
Output: payables ageing that ties to the ledger, claims cleared and payroll posted.
An agent can read bills from a mailbox, extract the fields, check for duplicates and propose the expense account and tax code. Payments and posting of unusual items stay with a person. Our guide to scanning receipts for GST claims covers the receipt side.
Day 4: accruals and adjustments
Goal: the profit and loss reflects the month, not the cash.
- [ ] Accrue costs incurred but not billed: utilities, rent, contractors, professional fees.
- [ ] Defer income received for work not yet done, and costs paid for future periods.
- [ ] Record depreciation using your policy.
- [ ] Revalue foreign-currency balances at month-end. See recording foreign currency expenses.
- [ ] Post recurring journals.
- [ ] Check intercompany and director balances.
Output: adjusting journals posted, each with a note of the reason and a source document.
This is the day with the most judgement. An agent can draft recurring journals and propose accruals from last month's pattern. A person decides every number that depends on an estimate.
Day 5: review and lock
Goal: the numbers are checked, the month is locked and the report goes out.
- [ ] Run the trial balance. Confirm debits equal credits.
- [ ] Compare each profit and loss line to last month and to the same month last year. Investigate variances above your threshold.
- [ ] Check the balance sheet: bank, receivables, payables, GST control account, payroll liabilities.
- [ ] Reconcile the GST control account to the return.
- [ ] Have someone other than the preparer review the pack.
- [ ] Lock the period in the accounting software.
- [ ] Send the management report to its readers.
Output: a locked month and a short report.
An agent can compute the variances, rank them by size and list the transactions behind each. It writes no explanation of cause that the data does not prove. The reviewer decides what the numbers mean.
The template
Copy this into a sheet. One row per task.
| Day | Task | Owner | Due | Evidence | Done | |---|---|---|---|---|---| | 1 | Bank accounts reconciled | | | Reconciliation report | | | 1 | Unmatched items assigned | | | Exception list | | | 2 | All sales invoiced | | | Delivery vs invoice check | | | 2 | Receivables ageing ties to ledger | | | Ageing report | | | 3 | Bills entered to cut-off | | | Bill list | | | 3 | Claims and payroll posted | | | Payroll journal | | | 4 | Accruals and deferrals posted | | | Journal with note | | | 4 | Foreign-currency revaluation | | | Revaluation journal | | | 5 | Trial balance and variance review | | | Variance list | | | 5 | Period locked | | | Lock log | |
What slows a close down?
- Late documents. Bills and receipts arrive after the cut-off. Fix with a shared mailbox and a rule that unsent claims roll to next month.
- No owner per task. Name one person for each row.
- Unreconciled bank accounts. Everything after day 1 depends on them.
- Judgement items left to the end. Start accrual estimates on day 3.
- No lock. Without a lock, last month changes quietly, and your report no longer matches what you sent.
Where KYN fits
KYN builds the close into the finance system: bills from Gmail, bank matching, receivables chasing and a variance report, in the client's own cloud account. Money, filings and posting wait for a named person, and every action is logged with the actor. KYN runs its own books the same way. See finance systems.
The first 14 days are a review of your stack and interviews with your team. A full build ships in under 90 days. Pricing is a one-off build fee, then a monthly retainer of at least twelve months, quoted after the review.
Frequently asked questions
Can a small company close in fewer than five days?
Yes, once the bank is reconciled daily or weekly and bills arrive in one mailbox. The five-day plan is a starting point, and many teams compress day 1 and day 2 into a single day after a few months.
Who should review the close?
Someone other than the person who prepared it. In a small team that may be the owner or an external accountant. The reviewer checks the trial balance, the variances and the lock.
What should an agent never do in a close?
Post estimates, release payments, file returns or edit a locked period. These carry money or legal weight and wait for a named person.
