In which scenario should a developer use child price lists?

Using child price lists is particularly advantageous when pricing needs to be tailored for specific products based on customer segments. This approach allows businesses to offer differentiated pricing for various customer groups, ensuring that special pricing agreements or promotional offers are implemented effectively. It enables a more flexible pricing strategy, where businesses can respond to the unique needs of particular customers, such as loyalty programs or region-specific pricing.

In contrast, the other scenarios would not benefit from the structure provided by child price lists. Fixed pricing typically suggests a uniform approach where the same price applies across the board, making child price lists unnecessary. In cases involving specific product pricing based on inventory, a more complex pricing model may be required that doesn't necessarily need child lists. Standardizing pricing across all products suggests a single price structure without the need for the complexity that child price lists introduce.
