Most close checklists are inherited. Somebody built one in a spreadsheet four years ago, people added rows, and now it is a list of nouns with no owners. It survives because nobody wants to be the person who deleted a step and caused a restatement.

The rewrite is worth doing, because the shape of the checklist has changed. Half the lines on a 2020 checklist are now machine work: they should be running continuously in the background, not waiting in a queue for a person on day three. What follows is the 2026 version: same coverage, different owners.

Pre-Close
Bank Reconciliation
Subledger Tie-Out
Accruals
Intercompany
Flux Analysis
Sign-Off

Days −5 to −1: the pre-close (this is where the close is won)

Every day of close you save is almost always saved before the period ends. If reconciliations only start on day one, you have already lost.

AUTO / Rolling bank reconciliation: Reconcile daily against the bank feed all month. On day one there is nothing to reconcile, only breaks to review.
AUTO / Subledger tie-outs: AP, AR, fixed assets, and inventory tied to control accounts continuously. Differences surface the day they appear, not three weeks later.
AUTO / Intercompany matching: Match receivables to counterparty payables as transactions post. Chase the mismatch while both preparers still remember it.
HUMAN / Cut-off communication: Confirm AP invoice cut-off, expense report deadlines, and revenue cut-off with the business. This is a relationship problem, not a systems problem.
HUMAN / Known-items list: One-offs, unusual contracts, disputes. Write them down before they become a day-four surprise.

Days 1 to 2: assemble and reconcile

AUTO / Final bank and cash reconciliation: Close out the remaining timing items.
AUTO / Recurring accrual proposals: Drafted from open POs, unbilled receipts, and prior-period run rates. They arrive populated; someone approves them.
AUTO / GL anomaly scan: Round-dollar journals, weekend postings, out-of-band amounts, entries by unusual preparers. Flagged before the auditor gets there.
HUMAN / Estimates and reserves: Bad debt, warranty, obsolescence. AI assembles the evidence; a person signs the number.
HUMAN / Non-recurring accruals: The judgment ones. Legal, restructuring, bonus true-ups.

Day 3: consolidate and eliminate

AUTO / Intercompany eliminations: Elimination entries posted from matched pairs, with FX handled at the correct rate rather than plugged.
AUTO / Currency translation: Rates applied consistently; CTA calculated and explained.
HUMAN / Elimination exceptions: Unmatched intercompany above tolerance. Usually a timing or coding problem, occasionally a real one.
HUMAN / Consolidation review: Does the group trial balance make sense as a business, not just as a balanced set of numbers?

Day 4: explain

AUTO / Flux analysis: Every material variance versus prior period, budget, and forecast, decomposed to the transactions driving it, with source rows cited.
AUTO / First-draft commentary: The explanation written from the data, not from memory. It is a draft, and it should be treated as one.
HUMAN / The narrative: What the variance means, and what the business should do about it. Nobody outsources this.
HUMAN / Management review: Controller reviews the pack. This is the control, and it needs to be visible.

Day 5: report and sign

AUTO / Statement and board-pack assembly: Financials, KPI schedules, and supporting exhibits generated from the closed ledger, every figure traceable.
AUTO / Audit-trail package: Reconciliations, approvals, and exception resolutions bundled for the PBC list.
HUMAN / Sign-off: A person certifies. The system's job is to make it easy for them to prove why they were comfortable.

"If your checklist does not say who owns the line and what evidence closes it, it is not a checklist. It is a to-do list with a compliance costume on."

The four KPIs worth tracking

Days to close: Business days from period end to final statements. Median is around six. Know where you actually sit before you set a target.
Reconciliation completion: Percentage of balance sheet accounts reconciled. The target is 100%. There is no acceptable second number.
Post-close adjustments: Entries made after the close was called final. Top performers stay under two or three a month.
Restatements: Prior-period corrections. Under one or two per year, and each one should generate a process change, not just a fix.
Modern close checklist: machines do the moving, humans do the meaning

Run the AUTO Lines Continuously. Start Day One With the Work Already Done.

ChatFin executes the automatable half of this checklist against your existing ERP, continuously rather than at period end, and routes every exception to a named owner with the evidence attached. No ERP replacement, no data migration.

A five-day close is not a faster version of a fifteen-day close. It is a differently shaped one, where the mechanical work never sat in a queue in the first place.
