A. 

A claim for work, labor, services, materials or other articles shall be in writing and on forms approved by the Comptroller and furnished by the City. The claim shall state the name and post office address of the claimant; the place where, the time when and the City agency for which the work, labor, services, materials or other articles were furnished; the quantity, description and cost thereof; by whom ordered; and, if furnished pursuant to a contract, the number and date of the contract; and such other information as the Comptroller may require. The claim shall be filed with the head of the City agency contracting for such work, labor, services, materials or other articles.

B.

If the claim arose out of a contract with the City, the affirmation shall contain a statement that the items set forth in the claim have been furnished in conformity with the terms of the contract. The Comptroller shall have the power to prescribe the form of the affirmation and may require such other matters to be set forth therein as he may deem advisable for the best interest of the City.

C. 

The requirements of this section shall not apply to the regular monthly invoices submitted by any public utility corporation under the jurisdiction of the Public Service Commission.
