FAQ
Is this an AI inventory forecasting tool?
No. It is a formula-based reorder calculator for spreadsheet users.
Can I use this without Shopify?
Yes. The MVP only needs a CSV with SKU, stock, demand, and lead time fields.
What if I only know last 30 days of sales?
Use last_30_days_sales. The calculator estimates average daily demand from it.
Are my inventory numbers sent anywhere?
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.
Can I export the results?
Yes. The tool exports a result CSV with labels, formulas, and per-SKU explanations.
