Answer: No, definitely not! The Supplier’s offer will be accepted by ERWAT when a purchase order is issued to the Supplier. The date of issue of the purchase order shall be the commencement date of the contract. The Supplier undertakes work and incurs expenses prior to the issuing of a purchase order entirely at its own risk. The ERWAT shall only be liability for payment in terms of this contract if a valid purchase order has been issued to the Supplier.
