AI Agent for Month-End Close Automation: A Step-by-Step Blueprint for Finance Teams

You are a senior accountant reviewing a month-end trial balance for a US GAAP-compliant company. I have uploaded a trial balance CSV with the following columns: Account Number, Account Name, Account Type, Prior Period Ending Balance, Current Period Debit Activity, Current Period Credit Activity, Current Period Ending Balance.

Please perform the following analysis:

1. BALANCE SHEET RECONCILIATION
   - For each asset, liability, and equity account, calculate the change from prior period to current period (in dollars and as a percentage)
   - Flag any account where the change exceeds [INSERT YOUR MATERIALITY THRESHOLD — e.g., $10,000 or 10%]
   - For flagged accounts, note whether the movement direction is expected (e.g., a receivable account increasing is expected if revenue is growing; a reversal would be flagged as unusual)

2. INCOME STATEMENT CHECK
   - Identify the top 5 largest revenue variances from prior period
   - Identify the top 5 largest expense variances from prior period
   - Flag any expense account that exceeded its balance in the same period last year by more than [INSERT THRESHOLD]

3. INTERCOMPANY / ELIMINATIONS CHECK (if applicable)
   - Identify any account number containing "interco" or "elimination" in the name
   - Confirm whether corresponding debit and credit entries net to zero
   - List any intercompany accounts that do not balance

4. UNUSUAL ITEMS
   - Flag any account balance that is directionally inconsistent with US GAAP presentation (e.g., a negative cash balance, a credit balance in an asset account, a debit balance in a liability account) as these require human review

Output Format:
- Section 1: Table of flagged Balance Sheet accounts with: Account Name, Prior Balance, Current Balance, $ Change, % Change, Flag Reason
- Section 2: Top revenue and expense variances table
- Section 3: Intercompany reconciliation summary
- Section 4: Unusual items list with brief explanation of why each is flagged
- Section 5: Summary — total accounts reviewed, number flagged, estimated time to resolve flagged items

Write in the tone of a reconciliation workpaper that a CPA would review during audit fieldwork. For every number you cite, include the Account Number in brackets so I can verify it against my source data.

I am attaching two files: File 1 is the Actual Trial Balance for [MONTH] [YEAR] and File 2 is the Budget for [MONTH] [YEAR]. Both files share the same column structure: Account Number, Account Name, Account Type, and Balance.

Please perform a Budget vs. Actual variance analysis with the following requirements:

1. REVENUE VARIANCE ANALYSIS
   - For each revenue account, calculate: Actual, Budget, $ Variance (Actual minus Budget), % Variance
   - Classify each variance as Favorable (F) or Unfavorable (U) from a P&L perspective
   - Flag variances greater than [INSERT THRESHOLD, e.g., $50,000 or 10%]
   - For each flagged revenue account, draft a one-sentence possible explanation in plain English

2. EXPENSE VARIANCE ANALYSIS
   - Repeat the same analysis for all expense accounts
   - Flag any expense account where actuals exceeded budget by more than [THRESHOLD]
   - For each flagged expense, draft a one-sentence possible explanation

3. GROSS MARGIN CHECK
   - Calculate total actual revenue, total budgeted revenue, and the variance
   - Calculate actual gross margin % and budgeted gross margin %
   - Flag if actual gross margin % differs from budget by more than 2 percentage points

4. OPERATING EXPENSE CHECK
   - Calculate total actual OpEx vs. budget
   - Identify which three expense categories have the largest unfavorable variances

5. NARRATIVE DRAFT
   Based on all of the above, draft a 3–4 sentence management commentary paragraph that could appear in a monthly reporting package. Write it in third-person, past tense, US GAAP-appropriate language.

Important notes:
- I will review and edit all variance explanations — treat these as first drafts, not final commentary
- If you cannot determine a plausible cause from the data alone, write "Requires management review — no data-supported explanation available" rather than speculating
- Present all figures in thousands ($000s) with one decimal place

Using the variance analysis we just completed, please draft the full management narrative for [COMPANY NAME]'s [MONTH] [YEAR] financial close package. Here is the additional business context you should incorporate:

[PASTE YOUR NOTES HERE — e.g.: "The revenue increase was driven by the XYZ contract signed March 15. The engineering overage was due to three new hires starting mid-month. The accounts receivable increase reflects the XYZ invoice which is not yet due."]

Please produce the narrative in the following sections:

SECTION 1: EXECUTIVE SUMMARY (2–3 sentences)
High-level summary of the month — was it above or below expectations, and what were the one or two biggest drivers?

SECTION 2: REVENUE (1 paragraph)
Explain total revenue vs. budget and vs. prior year. Quantify the variance. Identify the primary business drivers. Note any revenue recognition items that affected the period.

SECTION 3: COST OF GOODS SOLD AND GROSS MARGIN (1 paragraph)
Explain gross margin performance. Quantify any changes in COGS. Note significant cost drivers.

SECTION 4: OPERATING EXPENSES (1 paragraph)
Walk through major expense categories with variances above threshold. Note any one-time or non-recurring expenses that should be excluded from run-rate analysis.

SECTION 5: BALANCE SHEET HIGHLIGHTS (1 paragraph)
Comment on cash position and movement, accounts receivable aging if relevant, and any significant balance sheet changes.

SECTION 6: ITEMS REQUIRING MANAGEMENT DECISION
Bulleted list of items from the close that require a management decision or follow-up action.

Formatting requirements:
- Third-person, past tense throughout
- US GAAP-appropriate language
- Dollar amounts in thousands ($000s) with one decimal
- Percentages to one decimal place
- Avoid the word "significant" — use specific dollar and percentage figures instead
- Mark with [REVIEW NEEDED] anywhere you have inserted a placeholder or are unsure of the business driver
- Plain text only — no markdown, no asterisks, no pound signs. Use ALL CAPS for section headers.

Using the reconciliation analysis and variance commentary from this conversation, please produce audit-ready close documentation for [COMPANY NAME] for the period ending [DATE], prepared under US GAAP.

DOCUMENT 1: CLOSE PACKAGE COVER PAGE
- Company name, reporting period, date prepared
- Preparer name: [INSERT NAME] | Title: [INSERT TITLE]

Format all of the above as clean plain text that can be pasted into a Word document. Use ALL CAPS for document titles and section headers. Include [SIGNATURE LINE] placeholders wherever a human sign-off is required. Plain text only — no markdown, no asterisks.
