Which term refers to customer options that enhance their purchasing experience, like custom modifications?

The term that best describes customer options that enhance their purchasing experience, such as custom modifications, is "Add-on Services." This refers to additional services that a retailer may provide to enrich the main product or service being offered. For instance, if a customer is buying a piece of furniture, options like custom upholstery or delivery services would be considered add-on services. These services are designed to improve customer satisfaction and can significantly influence purchasing decisions.

The focus on enhancing the purchasing experience underscores the importance of personalization and customer service in retail. By providing these add-on services, retailers can differentiate themselves in a competitive market, ultimately leading to increased customer loyalty and potentially higher sales.

In comparison, while upgrades may involve enhancements to existing products, they don't necessarily encompass the range of additional customer experiences and modifications that add-on services do. Features refer more to the inherent characteristics of a product rather than customer options, and offers typically denote promotions or discounts rather than additional customization options.
