Engineering and Set-Up (E&S) is required for some but not all quotes.  This one time charge is added when additional engineering is required to manufacture a part.  Hart Enterprises, Inc. retains ownership of all E&S.  If the E&S needs repair or replacement, it is done at Hart Enterprises, Inc.’s expense, unless the part or capacity requirements are changed by the customer.  Half of the E&S must be paid within terms after receiving the PO.  The remaining 50% is due within terms after shipment of the parts.  E&S is fully refundable if Hart Enterprises, Inc. cannot manufacture the part to the specifications accepted by Hart Enterprises, Inc. with the purchase order.
