Month-end close follows the same structure every cycle — reconciliations, variance reviews, journal entry summaries, and a set of standard commentary that goes into the management pack. The numbers change every month. The structure, the format and most of the language do not.
Claude is well suited to this kind of recurring writing. Once you have a reconciliation or variance result, Claude can turn it into the commentary your management pack needs — consistently, in the format your finance director expects, every single month.
Key insight: Month-end close is one of the best candidates for a Claude workflow because it is genuinely the same task every month. Build the prompt once, reuse it every cycle.
Close checklists
Turn your standard close procedure into a clear, trackable checklist for the team.
Reconciliation narratives
Explain reconciling items and balance movements in clear, audit-ready language.
Variance commentary
Turn this month's variances into the commentary format your management pack requires.
Without Claude
Write reconciliation notes and variance commentary from scratch on day 3 of close, under time pressure, in inconsistent language each month.
With Claude
Paste this month's reconciliation results and variance figures. Claude drafts the commentary in the same format every month. You review and finalise.
These three prompts cover the core month-end writing tasks. Each one is built to be reused every cycle — paste this month's numbers in, get the commentary out, in the same structure every time.
Key insight: Build each of these prompts once with your preferred format, then save it. Every month you only need to change the numbers — the structure and tone stay consistent.
Prompt 1 — Month-end close checklist
Act as a Finance Manager. Turn the following month-end close steps into a clear, sequential checklist for the team, grouped by close day.
Our close process steps (in any order):
[List your close tasks — e.g. bank reconciliations, accruals, prepayments, fixed asset rolls, intercompany eliminations, journal review]
Close timeline: [e.g. 5 working days]
Team members involved: [e.g. AP, AR, GL, Financial Controller]
Format: group tasks by close day (Day 1, Day 2, etc.), assign each task to a role, and flag any task that depends on another task being completed first with [DEPENDENCY].
Prompt 2 — Reconciliation narrative
Act as a Financial Accountant. Write the reconciliation narrative for the following balance sheet account based on this month's reconciliation results.
Account: [e.g. Accrued Expenses / Intercompany Receivable]
Opening balance: [figure]
Closing balance: [figure]
Reconciling items: [List each item with amount and brief description]
Format: one paragraph explaining the movement from opening to closing balance, then a bullet list of each reconciling item with a one-line explanation. Audit-ready tone — clear and factual, no informal language.
Prompt 3 — Management pack variance commentary
Act as a Finance Business Partner. Write the variance commentary section of this month's management pack from the following data.
Period: [e.g. May 2026]
Variances (line item, budget, actual, variance):
[Paste your variance data — line by line]
House style notes: [e.g. "Always explain the driver, not just the number", "Flag anything over 10% with [REVIEW]"]
Format: one short paragraph per material variance line, explaining the driver. Flag any variance over 10% with [REVIEW]. Professional, concise tone — suitable for the monthly board pack.
Month-end close involves sensitive financial data and tight deadlines — both of which make good prompt habits especially important.
Key insight: The biggest time saving comes from consistency, not speed. A reusable prompt that produces the same format every month saves more time over a year than a one-off fast draft.
Month-end close prompt checklist
Paste figures and account names only — never client names, employee names or bank account numbers
Always state the period and house style notes so Claude matches your management pack format
Cross-check every figure in the output against your trial balance before it goes in the pack
Save each working prompt once finalised — reuse it unchanged every month
Flag material variances for senior review — Claude flags them, a human decides what they mean
Use your enterprise account for close data
Month-end figures are commercially sensitive. Use your organisation's enterprise Claude account for any data tied to actual account balances.
Reuse, do not rebuild
Once a close prompt works well, save it exactly as is. The value compounds when the same prompt produces the same format every month — changing it monthly defeats the purpose.
Important: Claude drafts the narrative — it does not perform the reconciliation or verify the numbers. Every figure must be checked against your trial balance and source systems before the management pack is finalised.
