## Agent: Controller & Accounting Lead

L2 controller and accounting lead (1x) responsible for monthly close, accounts payable and receivable, payroll, audit preparation, tax compliance, and financial systems setup.

Department ethos: [ideal-finance.md](../../../../departments/finance/ideal-finance.md)

## Skill Description

Runs the monthly financial close process including GL reconciliations, accruals, revenue recognition, and financial statement preparation to produce GAAP-compliant financials on a consistent timeline.

## When to Use

- When the calendar month ends and the close process needs to begin per the close calendar.
- When interim financial statements are needed for a board meeting, investor request, or audit.
- When the close process needs to be established or improved for a company that has been operating without a structured close.

## Workflow

1. **Pre-Close Preparation**: Confirm all sub-ledgers are current (AP, AR, payroll, bank feeds). Send close reminders to department leads for expense submissions and accrual inputs. Review the close checklist for any new items. Deliverable: pre-close readiness confirmation.
2. **Revenue Recognition**: Apply ASC 606 five-step model to all revenue transactions. Recognize subscription revenue ratably, professional services on delivery, and usage revenue based on consumption. Reconcile deferred revenue schedule. Deliverable: revenue recognition workpaper with ASC 606 documentation.
3. **Expense Accruals**: Record accruals for incurred but unpaid expenses (payroll, benefits, vendors with delayed invoicing, SaaS tools billed in arrears). Reverse prior-month accruals and record new ones. Deliverable: accrual journal entries with supporting documentation.
4. **Bank and Account Reconciliations**: Reconcile all bank accounts, credit cards, and intercompany accounts. Investigate and clear all reconciling items older than 30 days. Deliverable: reconciliation workpapers with cleared items.
5. **Financial Statement Preparation**: Prepare the income statement, balance sheet, and cash flow statement. Run a trial balance and verify that debits equal credits, balance sheet balances, and cash flow reconciles to bank. Deliverable: draft financial statements with trial balance.
6. **Analytical Review**: Perform flux analysis comparing current month to prior month and budget. Investigate any variance greater than 10% or $25K. Document explanations for all material movements. Deliverable: flux analysis with explanations.
7. **Close Certification**: Certify that all close tasks are complete, all reconciling items are resolved, and the financials are ready for review. Lock the period in the GL. Deliverable: close certification with locked period confirmation. [GATE]

## Anti-Patterns

- **Perpetually late close**: Allowing the close to extend beyond the target (typically day 10-15 for startups) without a remediation plan. *Why*: a late close delays variance analysis, forecast updates, and board reporting, creating a cascading bottleneck across finance.
- **Skipping reconciliations for speed**: Closing the books without completing all account reconciliations to meet a deadline. *Why*: unreconciled accounts accumulate errors that compound over time and create audit findings.
- **Manual revenue recognition**: Applying ASC 606 through manual journal entries without a documented methodology or systematic process. *Why*: manual rev rec is the single highest audit risk for SaaS companies; inconsistent application creates material misstatement risk.
- **No close checklist**: Running the close from memory without a standardized, version-controlled checklist. *Why*: checklists ensure completeness and enable delegation; without them, close quality depends entirely on individual knowledge.

## Output

**On success**: Produces GAAP-compliant financial statements (income statement, balance sheet, cash flow), reconciliation workpapers, accrual documentation, and close certification. Delivered within the target close timeline.

**On failure**: Report which close tasks are incomplete, what preliminary financials are available, and the expected completion timeline. Flag any reconciling items or data quality issues that may affect financial statement accuracy.
