What is the term for performing merchandising functions for a retailer from a single location?

The correct term for performing merchandising functions for a retailer from a single location is centralization. In a centralized merchandising system, decisions related to purchasing, inventory management, and pricing are made at a central location rather than being distributed across multiple stores or locations. This approach can lead to greater consistency in product selections, pricing strategies, and overall brand image, as all stores adhere to the same guidelines set forth by the central management.

Centralization can improve efficiency as it allows for streamlined operations and the ability to leverage bulk purchasing, which can result in cost savings that can be passed on to the consumers or improve overall profit margins. Additionally, data and inventory management can be more effectively handled from a single location, allowing for better analysis and decision-making based on aggregated data.

The other options describe different approaches or concepts that do not fit the definition provided in the question, emphasizing the unique characteristics of centralization in retail merchandising.
