Open Supplier Performance

Safety Stock uses its current settings: service levels A 98% · B 95% · C 90%; healthy cover up to 90 days; OTIF target 95%; ABC, Excess, Reorder Point and Forecast use their current page settings. Below safety stock and at reorder point are different checks. Figures match the Master Report PDF.

Why StockLogic & frequently asked questions

Private (runs in your browser, zero server uploads) · Dynamic (Z-score and lead-time variance instead of fixed min/max) · Any CSV (Shopify, ERP, or SQL exports)

Inventory data is processed locally in your browser. Process Mapping sends pasted notes to an AI service.

Do I need an account to use StockLogic?

No. There is no sign-up, and each upload can hold up to 1,000 SKUs.

Does my inventory data leave my computer?

No. Every inventory calculation — ABC classification, excess stock and DIO, safety stock, reorder point and forecasting — runs in your browser, and nothing is stored on a server. Process Mapping is the only feature that sends the notes you paste to an AI service for analysis.

What files do I need to upload?

Plain CSVs: item and demand history (up to 24 monthly periods) and, for supplier performance, order book history of purchase-order lines — at least 6 months, preferably 12.

How are safety stock and the reorder point calculated?

Safety stock uses a Z-score for your chosen service level together with demand variability and supplier lead-time variability. The reorder point is then (average daily sales × lead time) + safety stock.
