How to Build a Month-End Close Process That Finishes on Time

A strong month-end close is not a sprint on the last business day. It is a repeatable sequence that starts before the month ends and finishes with a ledger someone can act on. Here is the order we recommend, and the decisions that matter at each step.

What should happen before the month actually ends?

Most close delays are caused by work that should have been done earlier. Post routine transactions weekly. Reconcile high-volume accounts, such as bank feeds and payroll, as they arrive rather than saving them. Agree a hard cut-off with the team: the date after which no one posts to the closing month without a note.

A pre-close checklist helps. List the recurring journals, the accounts that always need attention, and the evidence each requires. The list becomes your working paper index for the month.

How do you lock down the cut-off?

Cut-off errors are the most common defect in a closed set of books. Check the last few days of each bank and credit card account for unpresented items. Review supplier invoices dated in the month but received after it, and goods received near month end that have no invoice yet. Those belong in accruals, not next month.

Post a reversing cut-off journal if your policy is to keep the ledger clean of stragglers. The mechanics vary by system, so follow your own software's rules rather than assuming.

Which accounts get reconciled first?

Reconcile cash first. Every other reconciliation is easier once you know the bank position is right, because cash errors ripple into sales, purchases, and payroll. Then work outward: accounts receivable and payable control accounts against their ledgers, payroll against the payroll report, and VAT or sales tax against the return.

Reconcile balance sheet accounts, not just the busy ones. A stale balance on a clearing or suspense account is a finding, not a footnote. Investigate it or write it off with approval, and record what you did.

Where do accruals and prepayments come in?

Once the ledger is reconciled to reality, adjust it for economic reality. Accrue costs incurred but not invoiced: utilities, professional fees, unbilled subcontractor work. Defer costs paid in advance, such as annual insurance or subscriptions, and release the appropriate slice into the month.

Work from evidence, not estimates alone. A supplier schedule, a contract, or a prior-year pattern is support. Keep the calculation in the working papers so a reviewer can rebuild it.

What about depreciation, amortisation, and payroll journals?

Post the non-cash journals next: depreciation and amortisation on the fixed asset register, the payroll cost journal split between expense and balance sheet, and any stock or inventory adjustment to a counted quantity. Each should tie to a source document: the register, the payroll report, the count sheets.

How should the review work?

A second pair of eyes is the point of review, so it must not be the same person who posted the entries. Review the trial balance for accounts with unusual movements against prior months. Check that the journals above have support and that the reconciliations actually agree, with differences explained rather than netted off.

When is the month closed?

Close the period in the software once review is complete, so no late entries can silently change a reported number. If something surfaces afterwards, book a correcting entry in the open month and disclose it, rather than reopening a closed period without a trail.

What turns a closed ledger into reporting?

The last step is translation. Produce the profit and loss, balance sheet, and a short commentary that a non-accountant can read: what moved, why, and what it means for cash. Flag the decisions, such as a large accrual or a margin shift, in plain language.

Then hold a short retrospective. What slipped, what needed chasing, what surprised you? Feed that back into next month's checklist. A close process that improves a little each month is the one that finishes on time.
