This listing describes a toolkit for custom commerce administration interfaces, not a turnkey storefront. Prototype one merchant task such as reviewing an order or changing a product attribute. Connect it to a staging API and check permissions, error handling, and how changes appear in the underlying commerce system.
Custom tooling brings maintenance and security obligations. List which standard admin tasks still need to be built, and verify licensing and integration requirements. Compare the actual operator experience and development effort with the existing Merchant Center workflow.
