The month-end close, in five clean stages.

Stage 1 · Collect (days 1 to 2)

• Pull every bank and card statement the moment it is available; do not wait for the slow ones to start the fast ones.
• Chase missing documents with a standard nudge on day 2, not a heroic scramble on day 8.
• Log what arrived against a per-client account list, so a missing account is caught now, not at reconciliation.

Stage 2 · Enter (days 2 to 3)

• Get every transaction into QuickBooks, whether QuickBooks Online or any Desktop version, from the statements, not from memory or feeds alone.
• Classify to the client's chart of accounts using the same rules as last month. Consistency now saves review time later.
• Flag anything genuinely ambiguous for the review pass instead of guessing.

Stage 3 · Reconcile (day 3 to 4)

• Tie each account: transaction count, total credits, total debits, ending balance against the statement.
• Investigate every difference to zero. "Close enough" in month 1 becomes a mystery in month 6.
• Clear stale uncleared items past your threshold with the client, not silently.

Stage 4 · Review (day 4 to 5)

• Scan the P&L and balance sheet against last month and the same month last year; explain the swings before the client asks.
• Check the classification flags from stage 2, loans, transfers, owner draws, and anything touching payroll or sales tax.
• Confirm accruals, depreciation, and recurring journal entries posted.

Stage 5 · Deliver (day 5)

• Send the package the same day the review closes: statements tie out, reports attached, notes on anything unusual.
• Record the close date per client. The trend of that date is the health of your practice.
• Write down the one thing that slowed this close, and fix it before the next one.

The habit that makes it stick

Run the same five stages for every client, every month, in writing. The checklist is not there for the easy months; it is there so the hard ones look exactly like the easy ones, just with more statements.
