Implementing these steps ensures your financial records are always up-to-date and reliable, paving the way for sustainable growth and operational efficiency.

Deep Dive
Step 1: Reconcile Bank and Credit Card Accounts
What to do: Compare your company’s bank statements and credit card statements against your general ledger entries. Verify that every transaction in your bank/credit card statement is recorded in your accounting software and vice versa.
Why it matters: This is often the first and most critical step. It ensures that all cash inflows and outflows are accurately captured, preventing discrepancies that can ripple through your entire financial system. It’s also a primary control point for detecting fraud or errors.
How to execute it correctly: Access your bank and credit card statements (ideally digitally). Within your accounting software, initiate the reconciliation process for each account. Match transactions one by one, investigating any unmatched items immediately. Ensure beginning and ending balances align perfectly with the statements.
Common pitfalls: Delaying reconciliations, leading to a large backlog of transactions. Failing to investigate small discrepancies, which can mask larger issues. Not reconciling *all* business accounts, including less active ones.
Step 2: Process Accounts Receivable (AR)
What to do: Ensure all invoices for goods or services delivered during the month are issued, recorded, and accurately reflect current balances. Reconcile customer payments received against outstanding invoices.
Why it matters: Accurate AR management directly impacts cash-flow visibility. It ensures you know exactly how much money is owed to your business and by whom, facilitating effective collections and revenue recognition.
How to execute it correctly: Run an Aged Accounts Receivable report. Follow up on overdue invoices promptly. Apply all customer payments received during the month to the correct invoices. Review any credit memos or adjustments made to customer accounts. Consider streamlining this with professional outsourced bookkeeping services.
Common pitfalls: Not issuing invoices promptly, leading to delayed payments. Failure to consistently follow up on overdue accounts. Inaccurate application of customer payments, resulting in open invoices that are actually paid.
Step 3: Manage Accounts Payable (AP)
What to do: Verify all vendor bills for the period are entered into your accounting system, approved, and scheduled for payment. Reconcile vendor statements with your internal records to ensure all liabilities are captured.
Why it matters: Accurate AP is crucial for managing your outgoing cash flow and ensuring all expenses are recognized in the correct period. It prevents missed payments, maintains vendor relationships, and provides a clear picture of your short-term liabilities.
How to execute it correctly: Collect all vendor invoices for the month. Enter them into your system, ensuring proper coding to expense accounts. Reconcile vendor statements against your AP ledger to identify any missing bills or payment discrepancies. Accrue for any unbilled expenses where the service or good was received, but the invoice hasn’t arrived yet.
Common pitfalls: Entering bills late, leading to misstated expenses for the period. Not accruing for unbilled services, understating liabilities and expenses. Duplicate payments due to lack of a robust approval process.
Step 4: Review and Accrue Payroll
What to do: Confirm that all payroll for the month has been accurately processed and recorded. This includes wages, salaries, taxes, and benefits. Accrue for any payroll that was earned but not yet paid at month-end.
Why it matters: Payroll is often a significant expense. Accurate recording ensures correct expense recognition, proper liability for unpaid wages/taxes, and compliance with payroll tax regulations.
How to execute it correctly: Obtain payroll reports from your payroll provider. Verify the total gross wages, employer taxes, and benefit contributions match your internal records. Create journal entries to record payroll expenses and liabilities. If your month-end doesn’t align with a payroll cycle, calculate and accrue for the portion of payroll earned but not yet paid.
Common pitfalls: Not reconciling payroll reports to general ledger entries. Failing to accrue for month-end payroll, understating expenses and liabilities. Incorrectly coding payroll expenses.
Step 5: Record Adjusting Journal Entries (AJEs)
What to do: Post necessary journal entries to ensure revenues and expenses are recognized in the correct accounting period, regardless of when cash exchanged hands. This includes depreciation, amortization, prepaid expenses, and accrued revenues/expenses.
Why it matters: AJEs are fundamental to accrual basis accounting. They ensure your financial statements accurately reflect the economic activities of the period, providing a true picture of profitability and financial position.
How to execute it correctly: Review your chart of accounts for typical accrual accounts like prepaid insurance, deferred revenue, and accrued expenses. Calculate and post entries for depreciation of fixed assets, amortization of intangible assets, and monthly usage of prepaid items. Record any revenue earned but not yet invoiced, and expenses incurred but not yet billed.
Common pitfalls: Missing critical accruals or deferrals, leading to misstated profits. Incorrect calculation of depreciation or amortization. Not understanding the impact of these entries on financial statements.
Step 6: Reconcile Balance Sheet Accounts
What to do: Systematically review and reconcile all remaining balance sheet accounts (e.g., inventory, fixed assets, loans, equity). Ensure supporting documentation justifies each account balance.
Why it matters: The balance sheet provides a snapshot of your company’s financial health at a specific point in time. Reconciling these accounts ensures the integrity of your assets, liabilities, and equity, preventing material misstatements.
How to execute it correctly: For each balance sheet account, verify the ending balance by comparing it to external statements (e.g., loan statements) or internal sub-ledgers (e.g., fixed asset register, inventory reports). Investigate and resolve any discrepancies. For larger or more complex businesses, this often requires strategic virtual CFO support.
Common pitfalls: Neglecting to reconcile non-cash balance sheet accounts. Not maintaining supporting schedules for complex accounts like fixed assets or equity. Allowing unreconciled differences to accumulate.
Step 7: Generate and Review Financial Statements
What to do: Produce your Income Statement (Profit & Loss), Balance Sheet, and Statement of Cash Flows. Critically review these reports for accuracy, reasonableness, and insights.
Why it matters: These statements are your primary tools for understanding business performance and financial position. A thorough review ensures data integrity and helps identify trends, anomalies, or potential issues that require further investigation.
How to execute it correctly: Generate the reports from your accounting software. Compare current month figures to prior months, budget, and prior year. Look for unusual fluctuations in revenues or expenses. Ensure the Balance Sheet balances (Assets = Liabilities + Equity) and that the Cash Flow Statement correctly explains changes in cash. Discuss findings with key stakeholders, perhaps with fractional CFO guidance.
Common pitfalls: Rushing the review process. Only checking for mathematical errors instead of analytical review. Not understanding the narrative the financial statements are telling about the business’s performance.

Examples & Scenarios
Consider a marketing agency that consistently receives a large utility bill after month-end. Without accrual entries, the utility expense for that month would be understated, making profitability appear higher than it actually was. By accruing the estimated utility cost, the financial statements accurately reflect the true cost of operations for that period.
Another example involves a consulting firm that pays its annual software subscriptions upfront in January. Without a prepaid expense adjustment, the entire cost would hit the January income statement, distorting its profitability. By deferring and then recognizing one-twelfth of the expense each month, the cost is matched to the period in which the benefit is received, providing a truer picture of monthly operational expenses.
Imagine a manufacturing company where inventory counts are off. If they don’t reconcile inventory at month-end, they might be overstating assets and understating cost of goods sold, leading to an artificially inflated profit margin. A thorough monthly close process would flag this discrepancy, allowing for investigation and correction, ensuring the balance sheet and income statement are accurate.
