What information does a retailer gather from documenting customer transactions?

The correct answer highlights the importance of gathering customer demographics as part of documenting customer transactions. Understanding customer demographics allows retailers to analyze who their customers are, including aspects such as age, gender, income level, and preferences. This information can inform marketing strategies, product offerings, and customer service improvements, ensuring that the retailer can effectively meet the needs and preferences of their target audience.

On the other hand, while employee performance metrics, pricing history, and supplier contracts are important aspects of retail operations, they do not directly stem from customer transaction documentation. Employee performance metrics relate more to staff assessments and operational efficiency, pricing history involves tracking changes in product prices over time, and supplier contracts deal with the agreements made with vendors. These areas, while critical in different contexts, do not provide insights into customer demographics from transactions.
