A month-end close checklist that actually closes the month

Most month-end close checklists fail for the same reason: they are a list of tasks rather than a sequence. Someone starts reconciling the bank account before all the transactions are in, finds a discrepancy that turns out to be a missing bill, and the whole thing restarts.

A close that runs to a date needs the work ordered so each step depends only on steps already finished.

Days 1 to 2: get everything in

Nothing reconciles until the population is complete.

• Confirm all bank, credit card and merchant feeds have pulled through the last day of the month
• Enter or import all outstanding vendor bills
• Post all customer invoices dated in the period
• Import payroll for any run with a pay date in the period
• Chase the two or three people who always submit expenses late

The last one is the real bottleneck in most businesses. If the same person delays the close every month, the fix is a deadline with consequences, not a reminder.

Days 2 to 3: reconcile

• Reconcile every bank and credit card account to the statement
• Reconcile merchant and payment processor deposits, including fees
• Reconcile accounts payable and accounts receivable subledgers to the general ledger
• Reconcile payroll liabilities to the provider’s reports

A reconciliation that “nearly” ties is not reconciled. Small unexplained differences compound, and by month nine nobody remembers where the first one came from.

Days 3 to 4: adjust

This is where most small finance functions stop early, and it is why their monthly numbers swing.

• Post depreciation and amortisation
• Release the month’s share of prepaid expenses
• Accrue for goods and services received but not yet invoiced
• Adjust deferred revenue for the period
• Review and clear the suspense account

The accrual step is the one skipped most often. Without it, a month where three large invoices happen to arrive late looks unusually profitable, and the following month looks unusually bad.

Day 5: review and report

• Review the P&L against prior month and against budget, and investigate anything that moved more than your materiality threshold
• Review the balance sheet account by account and confirm every balance is supported by a schedule
• Produce the reporting pack
• Write the variance commentary while the reasons are still fresh

The four steps teams skip

If your close is nominally finished but the numbers still surprise you, it is almost always one of these:

1. Accruals for unbilled costs. The single biggest cause of month-to-month volatility.
2. Balance sheet review. Everyone reviews the P&L. Errors hide on the balance sheet.
3. Suspense account clearance. An account that only grows is a list of unanswered questions.
4. Written commentary. If nobody writes down why revenue moved, nobody remembers by the board meeting.

Publishing the date

The last piece is the one that makes the rest work. Pick a close date, tell the business what it is, and hit it. A pack that arrives on day five every month is more useful than a perfect pack that arrives on day twenty.
