A 'closed' month means the books for that month are locked, balances are tied out, and you can issue statements that you'd stand behind.
Without a real close: numbers shift retroactively, comparisons across months are meaningless, and audit/lender requests become weeks-long fire drills.
Target: close prior month by the 10th–15th of the current month. Beyond 30 days, the data is too stale to drive decisions.
Use a written checklist (this one). Relying on memory is how items slip and the same errors recur.

Bank accounts: match every transaction in the GL to the bank statement. Investigate any difference.
Credit cards: same, including reconciling employee cards and reimbursable charges.
Loans / lines of credit: confirm principal, interest, and any fees match the lender statement.
Merchant processors (Stripe, Square, and PayPal): reconcile gross sales, fees, and net deposits; the timing differences cause headaches.
Payroll clearing: gross pay, taxes withheld, employer taxes, and net pay should net to zero each pay period.
Sales tax payable: amounts collected this month should match what's recorded as a liability.

Accrue revenue earned but not yet invoiced (unbilled receivables).
Accrue expenses incurred but not yet billed by vendors (utilities, services, professional fees).
Record depreciation on fixed assets.
Record amortization on prepaid expenses (insurance, software annual subscriptions, prepaid rent).
Adjust deferred revenue: revenue collected but not yet earned (annual subscriptions).
True up payroll accruals (PTO liability, year-end bonuses being earned ratably).

Accounts receivable aging: flag invoices over 60 days for collections; write off truly bad debt.
Accounts payable: confirm all vendor bills are entered; chase missing invoices.
Inventory (if applicable): physical count or cycle count tie-out.
Fixed asset register: additions and disposals booked, depreciation methods consistent.
Equity: owner draws and contributions tracked; distributions vs. expense correctly classified.
Run a comparative balance sheet (this month vs. the last three months) and investigate any unexpected changes.

Lock the period in the accounting software (QuickBooks, Xero, and Zoho Books all support this).
Generate the standard reporting pack: P&L (current month + YTD vs. budget), balance sheet, cash flow statement, A/R and A/P aging.
Hold a brief monthly review with the owner: 3–4 key takeaways, anything anomalous, decisions to make.
Document any judgment calls (write-offs, accrual estimates, reclassifications) in a close memo so next month's close is traceable.
