Supplier Furnished Equipment (SFE)
In aviation, when an aeroplane is made and delivered it will come with all agreed SFE equipment. The opposite of SFE is buyer furnished equipment BFE, which is installed after delivery by the buyer. Alternative terms are to call SFE forward fit and BFE retrofit. Typically the SFE is elegantly integrated appearing as a natural part of the original system. BFE in contrast often appears to be a late 'bolt on' that interrupts the smooth lines and operations of the original system.
