Why This Matters for Accounting & Bookkeeping
Month-end close is the backbone of accurate financial reporting. When the process varies by accountant or gets rushed, errors cascade into tax filings, client advisory work, and audit preparation. A standardized close procedure ensures every period is closed to the same standard, reduces the risk of material misstatements, and builds client trust in your numbers.
Common Mistakes
- ×Skipping bank reconciliation for accounts with low transaction volume, leading to undetected errors that compound over multiple periods
- ×Posting journal entries without memo descriptions, making it impossible to explain adjustments during audits or IRS inquiries
- ×Failing to lock the prior period in QuickBooks or Xero, allowing backdated entries that invalidate previously reviewed financials
- ×Not reversing accrual entries in the following period, causing double-counted revenue or expenses
- ×Reconciling AR and AP sub-ledgers to the general ledger only at year-end instead of monthly, creating large and difficult-to-trace discrepancies
Accounting & Bookkeeping-Specific Notes
Accounting firms handling multiple clients must standardize the close process across all engagements while accounting for client-specific chart of accounts, reporting requirements, and tax filing deadlines. GAAP compliance requires that accrual-basis financials reflect economic activity in the correct period. For tax-basis clients, confirm the appropriate recognition method with the tax manager before posting accruals. During busy season (January through April), consider an abbreviated close checklist for lower-risk clients to maintain throughput without sacrificing accuracy.
