In any case in which a contract is entered into upon a per unit basis, the head of the department, board or commission for whose benefit the contract is made shall make an estimate of the total amount to become due upon such contract, which estimate shall be certified in writing to the Finance Director. Such a contract may be entered into if the appropriation covers such estimate, or so much thereof as may be due during the current year. In such a case, the certificate of the Finance Director, based upon the estimate, shall be a sufficient compliance with the law requiring a certificate.
