CSV Inventory Reorder Calculator
Upload a CSV or try one SKU manually. Calculations run locally in your browser and use the same pure formula functions for CSV mode, single-SKU mode, and tests.
CSV files are processed locally in your browser. SKU names, product names, stock levels, prices, costs, and sales numbers are not sent to analytics. Analytics only records behavior events such as upload success, export click, and validation errors. No account or store connection is required.
Try one SKU
Not ready to upload a CSV? Try one SKU first, then use the CSV calculator when you want to rank multiple products.
Upload CSV for multiple SKUs
Start with a CSV export from your spreadsheet
Required: sku, current_stock, lead_time_days, and either average_daily_sales or recent sales history.
product_name, lead_time_variability_days, desired_service_level, minimum_order_quantity, incoming_stock, unit_cost, selling_price, last_30/60/90_days_sales.
- Reorder status for each SKU
- Safety stock and reorder point
- Suggested reorder quantity
- Per-SKU explanation and export CSV
Local processing: CSV files stay in your browser. Inventory names, stock levels, costs, prices, and sales numbers are not sent to analytics.
Formula notes
- Average daily demand uses average_daily_sales first, then last 30/60/90 day sales fallback.
- Safety stock uses demand variability, lead time variability, and service level z-score.
- Reorder point = average daily demand x lead time days + safety stock.
- Suggested reorder quantity fills to lead time plus 30 days of coverage, rounded up to MOQ.
These results are estimates. Review promotions, supplier capacity, cash constraints, seasonality, and business judgment before placing purchase orders.
