A merchant wishes to have a storefront for adult sized products and another for children's products. Payment and shipping methods will be the same for both. The category structure will be different. What is the minimum set up to accomplish this?

The Adobe Commerce architecture uses a hierarchy of Website, Store, and Store View. To meet the merchant's requirements, a single website is sufficient as payment and shipping methods are shared and can be configured at this level. The need for two different category structures mandates the creation of two separate stores, as each store is assigned its own unique root category. Finally, each store requires at least one store view to be visible on the frontend. This configuration represents the most efficient and minimal setup.

A. Two websites, two stores, two store views: This is incorrect because creating two websites is unnecessary. Since payment and shipping methods are the same, they can be managed under a single website, making this option not the minimum required setup.
C. One website, one store, two store views: This is incorrect because all store views within a single store must share the same root category. This configuration cannot support the requirement for two different category structures.

1. Adobe Commerce Developer Guide, Fundamentals, Basic concepts: "A website is the top-level container for sites, shipping methods, payment methods, and more... A store is a child of a website. Products and Categories are managed on the store level. A store has a single root category." This confirms that payment/shipping methods are managed at the website level, while the root category (which defines the category structure) is set at the store level.

2. Adobe Commerce User Guide, Stores, All Stores: The process for creating a new store explicitly requires the selection of a "Root Category". This demonstrates that to have a different category structure, a new store must be created. Conversely, settings for payment and shipping methods are typically configured at the website scope, allowing them to be shared by all stores within that website.

3. Adobe Commerce User Guide, Scope: "The scope setting determines the level of the configuration hierarchy where a setting applies... Website [scope]... includes all settings that apply to the base currency, taxation, and payment and shipping methods." This directly states that payment and shipping methods are a website-level configuration, reinforcing that only one website is needed.
