The companies which are handling "turnkey projects" are dealing in something which are ready for immediate use. The term which is very common in the construction industry where we commonly use a term "Ready to move flats" which refers bundling of materials and labour by sub-contractors. A "turnkey" job by a plumber would include the parts (toilets, tub, faucets, pipes, etc.) as well as the plumber's labour, without any contribution of the general contractors. This is commonly used in motorsports to describe a car being sold with drive train (engine, transmission, etc.) as a racer may prefer to keep the pieces to use in another vehicle to preserve a combination. Similarly, this term may be used to advertise the sale of an established business, including all the equipment necessary to run it, or by a business-to-business supplier providing complete packages for business start-up. In a turnkey business transaction, different entities are responsible for setting up a plant or equipment (e.g. trains/ infrastructure) and for putting it into operation. It can include contractual actions - at least through the system, subsystem, or equipment installation phase. It may also include follow-on contractual actions, such as testing, training, logistical, and operational support. It is often given to the best bidder in a procurement process. Turnkey projects can also be extended, known as turnkey plus, where there is perhaps a small equity interest by the supplier and it will later on continue its operation through a management contract or licensing. Turnkey is often used to describe a home built ready for the customer to move in. If a contractor builds a "turnkey home" they frame the structure and finish the interior. Everything is completed down to the cabinets and carpet.
