What type of marketing data can a business obtain by reviewing its inventory reports and customers' invoices?

By reviewing inventory reports and customers' invoices, a business can gain valuable insights into customers' product preferences. Inventory reports reveal which products are being sold and at what rates, while invoices provide direct information about the specific items customers are purchasing. Together, this data highlights trends in customer buying behavior, including which products are most popular and which are less frequently sold. Understanding these preferences allows businesses to tailor their marketing strategies, adjust their inventory, and develop new products that align with their customers' interests and demands.

In contrast, the other options focus on different aspects of business data that cannot be derived directly from inventory and invoice information. For example, while credit limits relate to financial assessments of customers, product quality and actual market share involve more complex evaluations than what is simply reflected in sales data. Understanding customers' preferences from sales documentation directly supports a business in making informed decisions about promotions, stock levels, and new offerings based on what insights are drawn from the products that have already resonated with their customer base.
