Close the BooksLocks a period so a later edit cannot quietly change what was already filed or reported. Close a month at a time to stay accountant-ready and a year when you file; every lock is reversible and every unlock is recorded.
Jun 2026 checklist
Nothing is waiting in the review queue.
No unmatched candidate transfers this month.
Accounts Receivable ($1,282.53) ties to the aging subledger.
Accounts Payable ($500.00) ties to the aging subledger.
2 accounts not reconciled through month-end: Business Checking, Checking.
Sales Tax Payable stands at $107.53 as of month-end — remit it before the filing deadline.
Apr 2025 is still open. Months close in order: this month's opening balances ARE Apr 2025's closing balances, and because the books lock on a single date, closing this one would freeze Apr 2025 anyway without ever checking that it ties out.
