How Quantzig’s Market Basket Analysis Empower You to Increase Quarterly Sales

Introduction to Market Basket Analysis

Market basket analysis (MBA) is a powerful data mining technique that enables retailers to gain valuable insights into customer purchasing behaviour by examining large datasets of transaction records. This approach identifies frequently purchased product combinations, revealing hidden patterns that can inform strategic decisions to boost sales and enhance the customer experience.

The widespread adoption of electronic point-of-sale (POS) systems has greatly facilitated the implementation of market basket analysis, as digital transaction data is more easily collected, stored, and analyzed compared to traditional handwritten records.

Quantzig enabled a major wholesale club retailer with over 600 locations in the United States and annual revenue exceeding $240 billion, in implementing market basket analysis. The client transformed its sales strategies through this implementation, substantially improving cross-selling revenue and inventory
management.

How to leverage Market Basket Analysis

Data Needed for Market Basket Analysis

Market Basket Analysis relies on transactional data collected from various sources such as point-of-sale systems, online shopping platforms, and customer databases. This data includes detailed information about each transaction, such as the products purchased, the quantity of each product, the date and time of the transaction, and the customer’s demographic information.

For example, Quantzig collected data from millions of customer transactions across the e-commerce platform and physical stores for the client. This information was used to gather insights into the products purchased together, the frequency of these purchases, and the customer’s shopping behavior over time.
