Everest is listed as a minimal e-commerce starter rather than a full hosted store. Clone a disposable copy and map what exists for catalog, cart, checkout, payment, tax, shipping, security, and admin operations. Complete a test purchase in a sandbox only after you know which parts are supplied and which you must implement.
A starter can accelerate a custom store but shifts responsibility to your team. Review its maintenance, dependencies, and deployment process. Compare the cost of building missing operations with a mature commerce platform before committing.
