A Practical Month-End Close Checklist for Growing Firms

A slow close costs you more than time. Decisions wait for numbers. Errors surface weeks late. Your team rushes the same tasks every month.

The fix is rarely a new tool. It is a written checklist, a fixed calendar and clear owners. This post gives you all three. Adapt it to your business, then run it for three months before you change it.

Set the target first

Pick a close deadline you can hit, not one you admire. If your close takes two to three weeks today, aim for business day 7 or 8 first. Once that holds, tighten to day 5.

Write down three things before you start:

• Close date: the business day the books lock.
• Owner per task: one name, not a team.
• Materiality threshold: the dollar amount below which you don’t chase differences. A $10M company might start at $500 to $1,000.

A close checklist only works if every line has one owner and one due day.

The close calendar, day by day

“Day 1” means the first business day after month end. Some work starts before that.

Keep this calendar in a shared tracker. Mark each task done with a date and initials. That record becomes your audit trail.

Before month end: the pre-close

The fastest closes start early. In the last week of the month:

1. Send approvers a reminder to clear invoices waiting in their queue.
2. Ask project and department leads for known costs not yet billed.
3. Confirm the payroll calendar and any bonus or commission runs.
4. Review open purchase orders for goods received but not invoiced.
5. Post recurring journal entries you already know, such as rent and software.

Each item you clear here removes a question on day 3.

Reconciliations

A reconciliation proves a general ledger (GL) balance matches an outside source or a supporting schedule. Unreconciled accounts are where errors hide.

Cash and cards

• Reconcile every bank account to the bank statement, not just the bank feed.
• Reconcile every credit card account, including cards held by individuals.
• Reconcile payment processor and merchant accounts. Match payouts net of fees to gross sales.
• Clear or explain every reconciling item older than 30 days.

Subledgers

• Accounts receivable (AR): the aging report total must equal the AR balance in the GL.
• Accounts payable (AP): the open AP report must equal the AP balance in the GL.
• Inventory: the inventory system value must match the GL, after any count adjustments.
• Fixed assets: the fixed asset register must match cost and accumulated depreciation.

Other balance sheet accounts

Reconcile every balance sheet account at least quarterly. Reconcile high-risk ones monthly. High-risk means large, volatile or manual. Examples include payroll liabilities, sales tax payable, loans and clearing accounts.

Every reconciliation needs a supporting file, a preparer, a reviewer and a date.

Accruals and adjustments

Accrual accounting records revenue when earned and costs when incurred, not when cash moves. Missed accruals are among the most common close errors.

Work through this list each month:

• Expense accruals: services received but not yet invoiced. Utilities, contractors, legal and freight are frequent gaps.
• Payroll accruals: wages earned between the last pay date and month end.
• Prepaid expenses: amortize annual software, insurance and deposits over the period they cover.
• Deferred revenue: cash received for work not yet delivered stays a liability until earned.
• Unbilled revenue: work delivered but not yet invoiced, common in services firms.
• Depreciation and amortization: post from the fixed asset register.
• Bad debt reserve: review aged receivables and adjust the allowance.

Document the basis for each accrual. “Estimate from last three invoices” is enough. Set accruals to reverse on day 1 of the next month, so you don’t double count.

Review

Review catches what reconciliations miss. Do it in two passes.

Flux analysis

Flux analysis compares each account to last month and to the same month last year. Set a rule, such as investigating any change over 10% and over your materiality threshold. Write a one-line explanation for each. “Higher freight due to two large shipments” is a good answer. “Timing” alone is not.

Sign-off

The controller reviews reconciliations, journal entries above a set amount and the flux notes. A second person approves any manual entry the preparer posted. After sign-off, lock the period in your accounting system. Any later change then needs a deliberate unlock.

The close pack

The close pack is what your owner, CFO or board actually reads. Keep it short and consistent. A good one fits in six to eight pages:

1. One-page summary: revenue, gross margin, operating expenses, net income and cash.
2. Income statement: month, year to date, budget and prior year.
3. Balance sheet with month-over-month change.
4. Cash flow summary and current cash position.
5. AR and AP aging, with notes on anything over 60 days.
6. Key variances, explained in plain sentences.
7. Open issues and decisions needed.

Use the same layout every month. Readers learn where to look, and changes stand out.

Common reasons closes run late

• Bank feeds treated as reconciliations.
• Approvers who hold invoices until after month end.
• Accruals rebuilt from scratch each month instead of from a template.
• One person who knows how everything works.
• Review that starts only after every task is done.

Each of these has a process fix. None needs a large budget.

Where to start

1. Write your close calendar this week, with one owner per task and a target day.
2. List every balance sheet account and mark each one for monthly or quarterly reconciliation.
3. Build an accrual template from last month’s close and reuse it next month.
