Month-End Close Checklist for Controllers

A practical month-end close checklist for Controllers, Accounting Managers, and Fractional CFOs at SMBs.

Month-end close is the most critical recurring process in any SMB finance team. A missed reconciliation, an uncaught duplicate, or a skipped prepaid can turn a clean close into a 9pm scramble. This checklist covers every step — from pre-close preparation through final sign-off — so Controllers can close faster and with fewer surprises.

1. Pre-Close Preparation

  • ☐ Confirm all bank feeds, credit card feeds, and payment processor feeds are updated.
  • ☐ Collect missing invoices, receipts, payroll reports, and vendor statements.
  • ☐ Confirm sales, revenue, and billing data has been posted.
  • ☐ Review prior-month open items and unresolved reconciliation issues.

2. Cash and Bank Reconciliation

  • ☐ Reconcile bank accounts to statements.
  • ☐ Reconcile credit cards and payment processors.
  • ☐ Review outstanding checks and deposits in transit.
  • ☐ Investigate unmatched transactions and duplicate entries.

3. AP, AR, Payroll, and Accrual Review

  • ☐ Reconcile AP aging and AR aging to the general ledger.
  • ☐ Review unpaid vendor bills and overdue customer balances.
  • ☐ Confirm payroll entries, taxes, and benefit accruals.
  • ☐ Review accruals, reversals, and deferred balances.

4. Prepaids and Fixed Assets

  • ☐ Review purchases above prepaid or capitalization thresholds.
  • ☐ Update prepaid and fixed asset schedules.
  • ☐ Record amortization and depreciation entries.
  • ☐ Reconcile schedules back to the general ledger.

5. General Ledger and Financial Review

  • ☐ Review month-over-month account variances.
  • ☐ Investigate unusual account spikes or drops.
  • ☐ Identify duplicate journal entries or repeated amounts.
  • ☐ Review income statement, balance sheet, and cash flow trends.

6. Final Close Review

  • ☐ Confirm all reconciliations are complete.
  • ☐ Confirm key schedules agree to the general ledger.
  • ☐ Review open items and document follow-ups.
  • ☐ Lock or close the accounting period if applicable.

Frequently Asked Questions

How long should month-end close take for an SMB?

High-performing SMB finance teams typically close within 3-5 business days. If your team is taking longer, the most common bottleneck is GL investigation — finding issues manually takes hours that a structured process can compress significantly.

What is the most time-consuming part of month-end close?

For most Controllers, GL investigation is the biggest time drain — identifying duplicates, miscoded vendors, missing coding, and unusual account movement. Finding these issues manually can take hours even when the fixes themselves take minutes.

Which accounting systems work with this checklist?

This checklist applies to any accounting system — QuickBooks Online, QuickBooks Desktop, NetSuite, Xero, or Sage Intacct. The steps are system-agnostic and follow standard close workflows.
