Sally places a purchase order to the supplier for some components that her company requires.

According to USLegal Inc, fitness for purpose refers to the standard that must be met by a seller in the course of a business. Generally, when a buyer makes known to a seller the particular purpose for which the goods are bought, there is an implied condition that the goods are reasonably fit for that purpose (customer's requirements, needs, or desires). Specification is the ground for deciding whether goods received are fit for purpose.

We already know that there are two types of specifications: conformance and performance specifications. With conformance specification, the buyer lists out technical requirements to which the goods must conform. Lacking of any requirement may be enough for the goods to be unfit. On the other hand, if performance specification is in use, the goods must be fit for specific outputs that buyer has listed in the specification.

Providing the 'fit for purpose' goods is one of the fundamental obligations of seller in sale contract. Unfulfilling this obligation would lead to legal consequences. If the goods are unfit for purpose, seller may have to:

- replace the non-conforming goods

- pay the damages to the buyer
