A month-end close checklist that survives staff turnover

A close checklist only works if it lives outside any single person — in a system that enforces order, assigns owners, and records what actually happened.

Phase 1 — Preflight (before touch-the-ledger work)

• Confirm QuickBooks sync is current for the period.
• Lock the service period in your workflow (month + entity).
• Pull uncategorized transaction count; set a materiality threshold for review.
• Verify bank and card statements are in Documents for the period.

Phase 2 — Preparation (agents or staff, same steps)

• Categorize or match transactions; queue exceptions — don't leave silent no-ops.
• Reconcile bank and credit card accounts; attach reconciliation summary.
• Post recurring entries and accruals from your firm's template.
• Run flux on revenue and major expense lines; note anything >10% move without a story.

Phase 3 — Review (human checkpoints)

• Manager review on reconciliation sign-off.
• Partner review on client-visible reports — nothing publishes before approval.
• Client questions drafted internally; send only after approval if policy requires.

Phase 4 — Close & deliver

• Flip approved reports to client-visible in the portal.
• Update close status on the service cycle; log blockers for next month.
• Capture one-line "what we learned" for firm memory (vendor rule, client preference).

The checklist isn't the innovation — enforcement is. When steps live in a workflow template, a new senior inherits the same sequence on day one. When agents handle preparation steps, turnover hits review capacity, not data entry capacity.

If your close still lives in a shared spreadsheet, you're one resignation away from a missed step. Move the checklist into the system that runs the month, not the system that remembers the month.
