Automates the tedious part of monthly close: writing explanations for every P&L and balance sheet line that moved materially versus prior period or budget. You set a threshold (default 5%), and it produces a table with actuals, variances, and a one-sentence driver for each flagged item. The key discipline is that drivers must explain why from underlying data (journal sources, vendor mix, headcount changes) pulled via MCP, not just restate the number in words. If the data doesn't support a clear explanation, it flags for controller review instead of making something up. Saves hours of spreadsheet staring and gives your CFO something readable.
