Shop upgrades increase the maximum number of furniture and heroes in your shop. Energy capacity is also affected by certain decorations. The Counter is your main source of Energy capacity, which is useful for suggesting and surcharging equipment to customers. Storage furniture (chest, shelf, and wardrobe) controls how much equipment you can hold for equipping or selling to customers, and is the maximum amount of each Special Resource you can hold. Each Rack grants bonus Energy when equipment of the corresponding type is sold to a customer.

Workstations limit your crafting speed and can be upgraded to allow faster crafting from higher level Workers. Resource Bins control your resource capacity and each have a resource regeneration rate, where having 3 bins will grant 3x faster regeneration for that type. Storing and placing furniture from storage has no penalty. Each piece of furniture can be stored in the Furniture Interface, and can be upgraded to increase it's functionality. Your Furniture types are Resource Bins, Workstations, Fusion Cauldron, Racks, Storage, and Counter. You can customize the layout of Furniture and Decorations in your shop.

Blueprints are unlocked by repeatedly crafting blueprints, by opening Inn Chests, by purchasing packages, and by completing City Raids. You will craft equipment from Blueprints in your crafting slots, and sell equipment to customers who enter your shop.
