No store connection
The MVP intentionally avoids Shopify API access. You stay in control by preparing a CSV and running formulas in the browser.
Shopify Inventory Forecasting for Small Business CSV Exports
This page is for Shopify sellers who want formula-based reorder planning from CSV exports without installing an app. The calculator does not predict demand or connect to Shopify; you provide SKU, stock, sales rate, lead time, and review period.
Single-SKU calculator
How the calculation works
Fields you need
At minimum, provide SKU, current stock, lead time, and either average daily sales or recent cumulative sales totals. Add review period and MOQ for a more useful reorder quantity.
When to use a full app
Use a full inventory app when you need automatic purchase orders, supplier workflows, multi-warehouse sync, or live marketplace data.
FAQ
Does this connect to Shopify?
No. It is CSV-first and does not ask for store access.
What Shopify fields do I need?
You need SKU and stock, plus your own sales rate or recent sales totals. Lead time usually comes from supplier records.
Can I use it for non-Shopify stores?
Yes. Any seller with a compatible CSV can use the calculator.
