A month-end close is a fixed sequence: capture every document, reconcile every account, accrue what is owed, review, and lock the period. Agents can prepare most of the sequence, since the steps are rule-based. A named person approves the reconciliations, adjustments and the lock. Use the checklist below as a template, and mark each step as agent-prepared, person-approved or person-only.
Why use a checklist?
A close fails in the same places each month: a missing bill, an unmatched bank line, a forgotten accrual. A written sequence makes the failure visible early. It also tells you what to automate. Steps that repeat with the same rule every month are candidates. Steps that need judgement stay with a person.
Set a target calendar and measure against it: working days to close. Do not set a number from someone else's benchmark. Measure your last three closes and aim to shorten them step by step.
The checklist
| No. | Step | Agent prepares | Person approves | |---|---|---|---| | 1 | Capture all bills, receipts and claims | Yes | Yes | | 2 | Reconcile every bank and card account | Yes | Yes | | 3 | Review receivables and chase | Yes | Yes | | 4 | Review payables and unpaid bills | Yes | Yes | | 5 | Accruals and prepayments | Drafts | Yes | | 6 | Payroll and CPF entries | Prepares | Yes | | 7 | GST review | Summarises | Accountant | | 8 | Management review of the numbers | Flags movements | Yes | | 9 | Lock the period | No | Yes, person only |
Step 1. Capture all documents
Cut-off first. Agree the date after which a document belongs to next month. The agent checks mailboxes, the WhatsApp claims number and portals, and lists what arrived. The person looks at the list of suppliers who usually bill monthly and have not. A missing recurring bill is the commonest accrual error. See how an agent reads supplier bills from Gmail and expense claims by WhatsApp photo.
Step 2. Reconcile every account
The agent matches statement lines to ledger entries by tier and lists exceptions. The person clears each exception and signs the reconciliation: bank balance, ledger balance, explained difference of zero. Include card accounts and payment platforms. See bank reconciliation with an AI agent.
Step 3. Review receivables
The agent produces the aged receivables list and the reminder log. The person decides on credit holds, write-offs and provisions. The reminder ladder is in invoice chasing agent: 3, 14 and 30 day reminders.
Step 4. Review payables
The agent lists bills received and unpaid, by due date and by supplier, and flags bills received after cut-off that relate to the month. The person confirms what is disputed or held.
Step 5. Accruals and prepayments
The agent drafts the entries from rules: recurring bills not yet received, annual subscriptions to spread, goods received not invoiced. Each draft shows its basis. The person approves, amends or rejects. Do not let an agent post accruals unattended: an accrual is an estimate and reaches the reported profit.
Step 6. Payroll and CPF
Payroll runs on its own cycle. For the close, the agent checks that payroll journals, CPF and other payroll liabilities are booked for the month and match the payroll reports. The person approves. Check current CPF rules with the CPF Board rather than from memory.
Step 7. GST review
The agent summarises GST by tax code with a drill-down to source bills and flags unusual items. The accountant confirms claimability and treatment. See GST on bills: what an agent can code and what an accountant must confirm.
Step 8. Management review
The agent compares each line with last month and the same month last year, and flags movements beyond a threshold you set. The person reads the flagged lines and asks why. The question stays with a person because the explanation is usually outside the data: a one-off project, a price change, a missed bill.
Put the figure and its change in front of the reviewer. Leave interpretation to them.
Step 9. Lock the period
Locking stops further postings into the month. It is the control that keeps reported numbers stable. Only a named person can lock or reopen a period, and the log records who and when. An agent must never lock or reopen a period.
How should the agent steps run during the month?
Do not wait for month end. Run the daily steps daily: capture, matching, reminders. By the last working day, most exceptions are already cleared. The close becomes a review of a short list. A manufacturer we built for gets a 06:30 morning report on WhatsApp per department, so the open items are visible each day, not at close.
What can go wrong?
- Silent cut-off drift. Documents posted to the wrong month. Check the cut-off rule in the capture step.
- Auto-matching a wrong line. Keep matching conservative. See the reconciliation article above.
- Stale rules. A rule that fit last year fits no longer. Review rules each quarter.
- No owner. Every step needs a named person. Write the names on the checklist.
What does a close calendar look like?
A checklist needs dates. Here is an illustrative calendar for a company that closes by the fifth working day. Adjust it to your own deadlines.
| Working day | Step | Owner | |---|---|---| | Last day of month | Cut-off: final bills and claims submitted | Team | | Day 1 | Bank lines matched, exceptions listed | Agent, then finance | | Day 1 | Receivables ageing refreshed | Agent | | Day 2 | Accruals proposed from open purchase orders | Agent, then finance | | Day 3 | Payroll journal and CPF reconciled | Agent, then finance lead | | Day 4 | Review of flagged items and adjustments | Finance lead | | Day 5 | Reports drafted, period locked | Named person |
Every row has an owner. The agent rows end in a person, never in a posted entry. If a step slips, the checklist shows which one and who holds it. Review the calendar quarterly and cut any step nobody can explain.
How do you handle a late close?
Some months slip. Decide in advance what happens. If bank matching leaves exceptions, close with a listed accrual and a note, then clear them next month. If a supplier bill has not arrived, accrue from the purchase order and tag it for reversal. If payroll changes after the lock, post it in the next period with an explanation, not a reopened month. The rule is that a locked month stays locked except by a named person's decision, recorded in the log. Keep a short list of slipped items each month. Repeated items show where the process needs fixing.
Where KYN fits
KYN runs its own books on this pattern: bills from Gmail, receivables chased at 3, 14 and 30 days, and payroll on 2026 CPF rules. Client systems run in a cloud account in the client's name. Every action is logged with the actor, and money, filings and period locks wait for a named person.
The first 14 days map your current close step by step, with the people who run it. A full build ships in under 90 days. See finance systems.
Frequently asked questions
How long should a month-end close take?
It depends on your volume and systems. Measure your last three closes in working days, then shorten the longest step first. Compare against yourself, not a published average.
Can an agent post the closing entries?
It can draft them. A named person approves, and only a named person locks the period.
Which step should we automate first?
Start where the rule is clearest and the volume is highest: usually bank matching and document capture. They free the most time and carry the least judgement.
