Monthly Close Process

What Is the Monthly Close Process?

The monthly close (or month-end close) is the process of finalizing all financial transactions for a given month, ensuring accuracy, and producing financial statements. It's the backbone of good financial management — without a clean close, you can't trust your numbers.

The average company takes 6-10 business days to close their books. Best-in-class organizations close in 3-5 days. The difference? A systematic, documented process with clear ownership and deadlines.

Monthly Close Checklist

Phase 1: Pre-Close (Day 1-2)

• Review and post all pending transactions
• Ensure all invoices are entered and posted
• Process and post all credit card transactions
• Verify all deposits are recorded
• Follow up on missing vendor invoices
• Complete timesheet and payroll entries
• Post intercompany transactions

Phase 2: Reconciliation (Day 2-3)

• Bank reconciliation — all accounts
• Credit card reconciliation
• Accounts receivable reconciliation — age and review outstanding
• Accounts payable reconciliation — verify completeness
• Inventory reconciliation (if applicable)
• Fixed asset reconciliation and depreciation
• Prepaid expenses — amortize current month's portion
• Accrued liabilities — review and adjust

Phase 3: Adjustments (Day 3-4)

• Post depreciation entries

Phase 4: Review & Finalize (Day 4-5)

• Compare month-over-month — flag unusual changes
• Review P&L for completeness and accuracy
• Review balance sheet — all accounts reconciled?
• Generate financial package (P&L, BS, CF, KPIs)
• Manager/owner review and sign-off
• Lock the period in accounting software

Best Practices for Faster Closes

1. Create a Close Calendar

Map out every task, who's responsible, and when it's due. Publish it so everyone knows the timeline. A close calendar eliminates the "I didn't know I needed to do that" problem.

2. Automate Recurring Entries

Set up recurring journal entries for predictable items: depreciation, amortization, rent, insurance. This eliminates manual entry and reduces errors.

3. Reconcile Continuously

Don't wait until month-end to reconcile. Weekly bank reconciliation means month-end is just a verification step, not a discovery process.

4. Use a Closing Binder

Maintain a digital "closing binder" with all supporting documentation for each close. This makes audits easier and ensures nothing falls through the cracks.

5. Hold a Post-Close Review

After each close, spend 15 minutes reviewing what went well and what didn't. Continuously improve the process. Track your close timeline — are you getting faster?
