# Income Statement Generation

> If you see unfamiliar placeholders or need to check which tools are connected, see [CONNECTORS.md](../CONNECTORS.md).

**Important**: This command assists with financial statement workflows but does not provide financial advice. All statements should be reviewed by qualified financial professionals before use in reporting or filings.

Generate an income statement with period-over-period comparison and variance analysis. Highlight material variances for investigation.

## Usage

```
/income-statement <period-type> <period>
```

### Arguments

- `period-type` — The reporting period type:
  - `monthly` — Single month P&L with prior month and prior year month comparison
  - `quarterly` — Quarter P&L with prior quarter and prior year quarter comparison
  - `annual` — Full year P&L with prior year comparison
  - `ytd` — Year-to-date P&L with prior year YTD comparison
- `period` — The period to report (e.g., `2024-12`, `2024-Q4`, `2024`)

## Workflow

### 1. Gather Financial Data

If ~~erp or ~~data warehouse is connected:
- Pull trial balance or income statement data for the specified period
- Pull comparison period data (prior period, prior year, budget/forecast)
- Pull account hierarchy and groupings for presentation

If no data source is connected:
> Connect ~~erp or ~~data warehouse to pull financial data automatically. You can also paste trial balance data, upload a spreadsheet, or provide income statement data for analysis.

Prompt the user to provide:
- Current period revenue and expense data (by account or category)
- Comparison period data (prior period, prior year, and/or budget)
- Any known adjustments or reclassifications

### 2. Generate Income Statement

Present in standard multi-column format:

### 3. Variance Analysis

For each line item, calculate and flag material variances:

**Materiality thresholds** (flag if either condition met):
- Dollar variance exceeds a defined threshold (e.g., $50K, $100K — ask user for their threshold)
- Percentage variance exceeds 10% (or user-defined threshold)

For flagged variances, provide:
- Direction and magnitude of the variance
- Possible drivers (if data is available to decompose)
- Questions to investigate
- Whether the variance is favorable or unfavorable

### 4. Key Metrics Summary

```
