Retail & Warehouse Inventory Management System in Excel | Sales | Purchases | Multi-Location | Power BI Dashboard

Description
The Retail & Warehouse Inventory Management System is a professional Excel-based solution designed for retailers, wholesalers, distributors, warehouses, importers, resellers, e-commerce businesses and multi-location organizations that require better visibility and control over their inventory operations.

The system connects the complete inventory lifecycle in one structured workbook. Users can maintain product, customer, supplier and location master data; prepare purchase orders; record goods received; manage purchase and sales returns; enter sales transactions; process inter-location stock transfers; perform physical stock counts; and monitor inventory movements through a centralized stock ledger.

The Inventory Control module calculates On Hand, Committed, Available, On Order, In Transit, Expected Receipts, Projected Available, Standard Cost inventory value and stock status by SKU and location. This provides a clear operational view of inventory across stores, warehouses and bins.

The Reorder & Replenishment module calculates Average Daily Sales, Lead-Time Demand, Safety Stock, Reorder Point, Days Cover, Expected Stockout Date, Economic Order Quantity, Recommended Reorder Quantity, Estimated Reorder Cost, Replenishment Priority and Stockout Risk. A separate Demand Forecast module analyzes transaction history using recent averages, sales velocity, seasonality and adjustable planning assumptions.

Inventory Intelligence includes ABC Analysis, XYZ Analysis, the ABC-XYZ Matrix, inventory aging, movement classifications, slow-moving and dead-stock identification, excess inventory, inventory turnover, Days Inventory Outstanding and cash tied up in inventory.

Supplier Performance evaluates purchase value, order volume, accepted and rejected quantities, lead times, on-time delivery, late deliveries, supplier returns, purchase-cost movement, supplier dependence and overall supplier score.
Three BI-style Excel dashboards provide dedicated views for executives, warehouse managers and replenishment teams. The SKU 360 module provides a complete product-level profile covering stock, locations, sales history, purchasing, supplier information, classification, inventory risk and recommended action.
The professional package includes a 23-worksheet Excel workbook, a detailed 36-page User Manual and a 12-page Quick Start Guide. The workbook is formula-driven, requires no mandatory VBA and contains no external workbook links. Microsoft Excel 2019 or Microsoft 365 is recommended.

All included companies, suppliers, customers, products, quantities and financial figures are fictional demonstration data and must be replaced before operational use. The workbook uses Standard Cost valuation and does not claim FIFO, LIFO or weighted-average accounting. It is a management planning and inventory-control model, not a statutory accounting ledger, ERP, POS or certified warehouse-management system.
