InventoryLoop: Reorder & PO

InventoryLoop turns sales history and current stock into explainable reorder suggestions. Out-of-stock days are excluded from sales velocity, and every recommendation shows its reasoning. Create purchase orders per supplier as PDFs or send them by email. Record partial receipts; landed costs are allocated across items and stock is written back to Shopify. Reports show stock value, slow movers, coverage, and calculated product margin. Customer contact data is not processed.
