# Inventory Guide

## Stock Status Thresholds

| Status       | Days of Supply | Meaning |
|--------------|---------------|---------|
| out_of_stock | 0 days         | No inventory; sales halted |
| critical     | < 3 days       | Near-zero; risk of stockout within hours |
| low          | 3–14 days      | Insufficient buffer; reorder urgently |
| healthy      | 14–60 days     | Adequate buffer for normal demand |
| overstocked  | > 60 days      | Excess inventory; review purchasing plan |

## Reorder Quantity Calculation

When `reorder_needed` is true, compute the exact reorder point and suggested order quantity by running the calc_reorder script with:
args={"product_id": "<product_id>", "daily_demand": <daily_demand>, "lead_time_days": 7, "safety_days": 3}

The script returns:
- `reorder_point` (integer): minimum stock level that triggers a reorder
- `reorder_qty` (integer): suggested quantity to order
- `safety_stock` (integer): buffer stock to cover demand variability

Present the `reorder_qty` to the user as the recommended order size.

## Escalation Rules

| Status              | Action |
|---------------------|--------|
| out_of_stock        | Notify procurement manager immediately; explore emergency sourcing |
| critical            | Alert supply chain team; request expedited shipment |
| low                 | Submit standard reorder; flag for daily monitoring |
| overstocked > 90 days | Request review from merchandising team; consider promotions |

## Seasonal Adjustments

During peak seasons (Q4 holiday, back-to-school), adjust thresholds:
- Treat `low` as `critical` (demand spikes reduce effective days-of-supply)
- Add 20% to the safety stock calculation
