How the Inventory Forecasting Prompt works

Turn cleaned sales and supply inputs into a reviewable reorder proposal rather than an automatic purchase order. Using the prompt is simple; judging seasonality, lead times, stockout cost, promotion effects, and working-capital risk requires an experienced operator.

02

Key instructions and output

This prompt asks the model to estimate stock needs from sales history and draft reorder suggestions; the points below reflect instructions present in the source text.

01

Uses inventory signals for operating decisions

The source works with stock, demand, or reorder information to identify what should be replenished, monitored, or investigated.

02

Structures the analysis before making a recommendation

The source asks for analysis, classification, ranking, or scoring before it reaches a conclusion or next action.

03

Copy the complete prompt

The complete source is shown below. Copy it from the top right to use it.

Act as an inventory planning analyst for an ecommerce business. Given sales history data, generate:

1. DEMAND FORECAST:
- 30-day projection by SKU
- 90-day projection for top sellers
- Seasonality adjustments (month-over-month patterns)
- Confidence intervals (high/low estimates)

2. REORDER RECOMMENDATIONS:
- Which SKUs to reorder this week (stockout risk < 30 days)
- Optimal order quantities (EOQ calculation)
- Lead time buffer recommendations
- Minimum order quantity considerations

3. RISK ASSESSMENT:
- Products at risk of stockout (ranked by revenue impact)
- Overstock items (> 90 days supply)
- Dead stock identification (> 180 days)

4. PROMOTION IMPACT:
- Expected demand spike for planned promotions
- Safety stock adjustment for promo periods
- Post-promotion demand dip estimate

5. CASH FLOW IMPACT:
- Estimated inventory investment needed this month
- Working capital tied up in slow-moving stock
- Liquidation recommendations for dead stock

Focus on actionable reorder dates and quantities. Flag anything that requires immediate attention with ⚠️.

01

Clean and label the data

What to check before using the output

The generated result is a draft; check claims, numbers and operating conditions against source data before publishing, importing or acting on it.

A chat instruction does not update inventory

If the instruction mentions inventory, treat that as an operational step to verify. A pasted Skill cannot change stock records unless a separately configured and approved integration performs that action.
