The UK Month-End Close Checklist: Closing in Five Working Days
Most UK SMEs close in eleven to fifteen working days. Five is achievable without more headcount — it comes from sequencing, hard cut-offs and moving review earlier. Here is the checklist.
The month-end close is where a finance function's credibility is either built or quietly eroded. Numbers that arrive on working day fifteen inform nothing; the operating decisions they related to have already been taken. The goal is not perfection on day fifteen — it is a materially accurate, reviewed set of numbers on day five.
Why closes run long
- Cut-off is treated as a suggestion, so late invoices reopen completed reconciliations.
- Tasks run sequentially when they could run in parallel — bank recs waiting on AP, AP waiting on approvals.
- Review happens only at the end, so errors are found after everything downstream is built.
- Recurring journals are rebuilt manually each month instead of templated.
- No one owns the checklist, so the same three items slip every month.
The five-day sequence
| Day | Focus | Output |
|---|---|---|
| Day 1 | Hard cut-off, cash and bank | All bank accounts reconciled to the last day of the period |
| Day 2 | AR, AP and payroll | Sub-ledgers agreed to control accounts; payroll journal posted |
| Day 3 | Accruals, prepayments, revenue recognition | Draft trial balance with all judgement entries posted |
| Day 4 | Balance sheet reconciliations and review | Every balance sheet line supported and reviewed |
| Day 5 | Reporting and commentary | Management accounts, KPI pack and variance narrative issued |
The 17-step checklist
- Apply a hard purchase-invoice and expense cut-off; communicate it two weeks in advance.
- Reconcile every bank account, including foreign currency and card accounts, to the statement.
- Post and reconcile card and expense platform feeds.
- Agree the AR sub-ledger to the debtors control account and review aged debt over 60 days.
- Agree the AP sub-ledger to the creditors control account and check for duplicate postings.
- Post the payroll journal and reconcile net pay, PAYE, NIC and pension to the bureau report.
- Post recurring accruals from templates, not from memory.
- Release prepayments and check the closing prepayment schedule agrees to the balance sheet.
- Review revenue recognition against contracts — deferred and accrued income both directions.
- Reconcile the VAT control account and agree the return position for the period.
- Review stock or WIP, including any provision movement.
- Post depreciation and reconcile the fixed asset register to the nominal ledger.
- Reconcile intercompany balances and confirm both sides agree before consolidation.
- Clear all suspense and holding accounts to nil.
- Perform a variance review against budget and prior month at account level, not just total.
- Independent review of judgement entries above the materiality threshold, with sign-off recorded.
- Issue the management pack with written commentary on the three largest variances.
Controls that make a fast close safe
Speed without control is just an earlier wrong answer. Three controls do most of the work: a documented materiality threshold so trivial items do not consume review time; segregation between preparer and reviewer on every judgement entry; and an audit trail that records who posted what and when. All three also shorten the statutory audit later.
What to automate first
- Recurring journals — accruals, prepayments, depreciation — as templates rather than manual entries.
- Bank and card reconciliation via direct feeds.
- Intercompany matching, which is the most common cause of a late consolidation.
- Variance commentary drafting, so the reviewer edits a draft rather than starting from blank.
Measuring the close
Track three metrics monthly: working days to issue, number of post-close adjustments, and percentage of checklist items completed by their target day. If days-to-issue falls while post-close adjustments rise, you have not accelerated the close — you have moved the errors downstream.

Frequently asked questions
How long should a month-end close take for a UK SME?
A well-run SME finance function closes in five working days. Ten to fifteen days is common but usually reflects sequencing problems — reconciliations waiting on each other — rather than a lack of resource.
What is the biggest single cause of a slow close?
Soft cut-off. If purchase invoices, expenses and timesheets keep arriving through day six, every downstream reconciliation has to be reworked. A hard cut-off with a standing accrual for late items removes most of the delay.
Do we need a formal close checklist if the team is only two people?
Yes, and arguably more so. A documented checklist with owners and days is what lets a two-person team close without one person holding the whole process in their head, and it is the first thing a lender or acquirer asks to see.
