Python & Excel for Retail Analytics: Sales Forecasting & Inventory: A Complete System for Demand Modeling, Stock Optimization, and Data-Driven Retail

By Hayden Van Der Post

Reactive Publishing

Retail has entered its algorithmic era. The brands that survive are the ones that forecast demand with precision, optimize inventory intelligently, and make decisions driven by real data rather than intuition. This book gives retail operators, analysts, and founders a complete, end-to-end blueprint for mastering the modern analytics stack using the tools that dominate the industry: Python and Excel.

This is a practical, battle-tested handbook that shows you how to transform raw retail data into strategic, revenue-driving insight. You will learn how to clean and structure datasets, engineer predictive features, build accurate sales forecasts, model seasonality and promotions, optimize stock replenishment, and automate the analytics workflows that typically take teams days to complete.

This is not theory. It is a field manual built for real operators in a fast-changing marketplace.

Inside, you will learn how to:
- Build forecasting models in Python and Excel, including time series, moving averages, ARIMA, Prophet, and machine-learning approaches.
- Diagnose demand volatility and set reorder points based on variability, safety stock, service-level targets, and lead-time uncertainty.
- Construct dynamic dashboards that track SKU performance, margin trends, supply chain bottlenecks, and sell-through velocity.
- Integrate Excel with Python to automate repetitive tasks, accelerate analysis, and produce enterprise-grade reporting.
- Use price elasticity, promotions impact modeling, ABC/XYZ analysis, and inventory stratification to drive profitability.
- Implement forecasting and inventory workflows that scale from small retail operations to national chains.

Whether you run a retail business, work in FP&A, manage supply chain operations, or want to break into the analytics field, this book equips you with the modeling skills, tools, and frameworks used by top retailers around the world.

Master the analytics that move product, shape demand, and protect margins. This book shows you how to build a smarter, more resilient retail operation, one forecast, model, and dataset at a time.
