Month End Close Checklist

A month end close checklist is the ordered list of tasks a finance team completes to lock a period and produce reliable financial statements. A workable close runs in four stages: cut off and collect source documents, reconcile every balance sheet account, post accruals and adjusting entries, then review, lock, and report. Most of the delay in a slow close comes from one place, waiting on invoices and statements that have not arrived or have not been entered.

Below is a checklist you can copy, ordered the way the work actually has to happen rather than by department. The sequence matters more than the length. Reconciling cash before the bank has posted the last day of the month, or accruing expenses before AP has finished entering invoices, guarantees you do the work twice.

What is the month end close?

The month end close is the process of finalizing a company's books for a completed accounting period so that the financial statements reflect everything that happened in that period and nothing that did not. It ends when the period is locked and no further entries can be posted without an approved reopening.

The discipline behind it is the cutoff. Every transaction belongs to exactly one period, decided by when the economic event occurred, not when the paperwork appeared or the cash moved. Almost every close error is a cutoff error: an invoice for December work entered in January, a January expense accrued twice, revenue recognized when the payment cleared rather than when the obligation was satisfied.

The month end close checklist

Stage 1: Cut off and collect (days 1 to 2)

Task	Owner	Why it comes first
Announce the cutoff date and stop posting to the prior period	Controller	Everything downstream assumes a fixed population of transactions
Chase and enter all vendor invoices received for the period	AP	The single largest source of close delay
Confirm all customer invoices for the period are issued	AR	Unbilled revenue distorts both revenue and receivables
Collect bank, credit card, and merchant statements	Accounting	Reconciliation cannot start without them
Close payroll for the period and capture unpaid wages	Payroll	Payroll accruals depend on the final register
Collect employee expense reports and corporate card activity	Accounting	Late reports become next month's problem entries
Capture inventory counts or cycle count results	Operations	COGS is unreliable without a period-end quantity

Stage 2: Reconcile (days 2 to 4)

Account	Reconcile to	Common exception
Cash and bank accounts	Bank statement balance	Outstanding checks, deposits in transit, bank fees not booked
Credit cards	Card statement	Personal charges, missing receipts, timing of statement close
Accounts receivable	AR aging subledger	Unapplied cash, credit memos posted to the wrong customer
Accounts payable	AP aging subledger and vendor statements	Duplicate invoices, invoices received but not entered
Inventory	Physical or cycle count	Goods received not invoiced, shrinkage, in-transit stock
Prepaid expenses	Amortization schedule	New prepaids never added to the schedule
Fixed assets	Fixed asset register	Capitalized items expensed, disposals never removed
Accrued liabilities	Supporting schedule	Prior-month accrual never reversed, causing a double count
Debt and interest	Loan amortization schedule	Principal and interest split incorrectly
Payroll liabilities	Payroll provider reports	Employer taxes and benefits accrued at the wrong rate
Intercompany balances	Counterparty ledger	Balances that do not eliminate on consolidation

A reconciliation is not done when the balance ties. It is done when every reconciling item is identified, explained, and either cleared or scheduled to clear. A cash reconciliation with a $412 unexplained variance is an open item, not a completed task, and unexplained variances compound quietly across periods.

Stage 3: Accruals and adjusting entries (days 4 to 5)

Entry	Trigger	Watch for
Reverse prior-period accruals	Every period, first	Skipping this double counts the expense
Accrue expenses incurred but not invoiced	Goods or services received	Utilities, legal fees, contractor work, freight
Accrue unbilled revenue	Performance obligation satisfied	Recognition rules under ASC 606
Record depreciation and amortization	Fixed asset and intangible registers	Assets placed in service mid-month
Amortize prepaid expenses	Prepaid schedule	Annual insurance and software renewals
Record deferred revenue movement	Contract terms	Cash collected before delivery
Book bad debt or allowance adjustments	AR aging	Policy consistency period to period
Record inventory adjustments and COGS	Count results	Standard cost variances
Post FX revaluation on foreign balances	Period-end rates	Using the wrong rate type for the account

Stage 4: Review, lock, and report (days 5 to 7)

Run a preliminary trial balance and confirm it balances.
Perform flux analysis: compare every material account against prior month and budget, and explain any variance beyond your threshold. This is the control that catches what the reconciliations missed.
Confirm no reconciling item is unexplained and no suspense account holds a balance.
Review the journal entry log for entries posted without support or approval.
Have someone other than the preparer review and sign off on each material reconciliation.
Lock the period in the accounting system.
Produce the income statement, balance sheet, and cash flow statement.
Distribute the management reporting package with commentary on the variances.
Log every issue and its root cause in a close file, so the next close is shorter.

How long should a month end close take?

Most small and mid-sized US companies close in five to ten business days. Well-run finance teams land in three to five. The number itself matters less than its variance: a predictable seven-day close is healthier than a close that sometimes takes four days and sometimes fifteen, because the volatile one is being held together by heroics rather than by a process.

If your close is slow, measure where the days go before you buy anything. The delay is almost never in the journal entries. It sits in Stage 1, waiting on documents, and in Stage 2, chasing reconciling items caused by bad data entered in Stage 1.

Why is the month end close so slow?

Four causes account for most of it, in order of frequency.

Invoices arrive late or are entered late. If AP is still keying December invoices on January 6th, nothing downstream can start. This is a throughput problem, and it is the one that responds best to automation, because invoice entry is mechanical work with a verifiable right answer.

Reconciling items are researched, not prevented. Duplicate payments, invoices coded to the wrong account, and payments applied to the wrong vendor all surface during reconciliation, where they cost ten times more to fix than at entry. Strong accounts payable internal controls and three-way matching prevent most of them upstream.

The checklist lives in someone's head. Undocumented closes fail when the person who knows the sequence is on vacation, and they hide the fact that a task was skipped entirely.

Everything happens at once. Teams that only reconcile at period end create a five-day crunch. Teams that reconcile cash weekly and clear the AP exception queue daily arrive at day one with most of the work already behind them.

How do you close the books faster?

The two changes with the largest effect are moving work earlier and removing keystrokes.

Moving work earlier means a continuous close: reconcile bank accounts weekly, review the AP aging and exception queue continuously, amortize prepaids on a schedule that posts automatically, and require expense reports within a fixed number of days rather than at month end. By the cutoff date, Stage 2 should be mostly finished.

Removing keystrokes means the source documents stop being retyped. Invoice capture is the highest-volume case: instead of an AP clerk keying vendor, date, invoice number, line items, and total off a PDF, an extraction tool reads the document and returns structured fields ready to import. That directly compresses Stage 1 and, because there is no typing, it removes the transposition errors that would otherwise appear as reconciling items in Stage 2. Our invoice data extraction software does exactly this step, and the broader case is covered in accounts payable automation software.

Reconciliation has the same shape. When a bank has no direct feed, the fallback is retyping a statement, which is slow and introduces errors into the one account you can least afford to be wrong. Converting the statement into a clean file first is faster and safer, and if the books live in QuickBooks you can turn the transaction file into an importable QBO instead of keying it line by line.

What is the difference between a month end close and a year end close?

A month end close finalizes one period and locks it. A year end close does everything the monthly close does, then adds the tasks that only make sense annually: closing revenue and expense accounts to retained earnings, finalizing depreciation and tax provisions, confirming balances with banks and major vendors, valuing inventory and reserves for the audit, and preparing the schedules an external auditor or tax preparer will request.

The practical implication is that a disciplined monthly close makes the year end close small. Companies that reconcile properly every month spend December confirming, not discovering. Companies that let reconciling items ride spend the audit explaining them.

Who should sign off on the close?

Someone other than the person who prepared the work. Preparer and reviewer must be different people for each material reconciliation and for the journal entries above your materiality threshold. This is not bureaucracy. It is the segregation of duties that auditors test, and it is the control that catches both honest error and the small, patient kind of fraud that lives inside an account nobody else looks at.

In a company too small to separate the roles fully, compensate with visibility: the owner or an outside accountant reviews the bank reconciliation and the vendor list every month. Reviewing two things consistently beats reviewing everything once a year.

The short version

Close in four stages, in order: cut off and collect, reconcile, accrue and adjust, then review, lock, and report. Reverse last month's accruals before you book this month's. Treat an unexplained variance as an open item rather than a rounding difference. Have a second person sign off on material reconciliations. Then attack the two real bottlenecks, which are late source documents and reconciling items created by manual entry, by moving reconciliation work into the month and taking the retyping out of it entirely.
