In those villages that have established the position of village administrator, as provided by section 735.271 of the Revised Code, the village administrator shall make contracts, purchase supplies and materials, and provide labor for any work under the administrator's supervision involving not more than fifty thousand dollars. When an expenditure, other than the compensation of persons employed by the village, exceeds fifty thousand dollars, the expenditure shall first be authorized and directed by ordinance of the legislative authority of the village. When so authorized and directed, except where the contract is for equipment, services, materials, or supplies to be purchased under division (D) of section 713.23 or section 125.04 or 5513.01 of the Revised Code, available from a qualified nonprofit agency pursuant to sections 4115.31 to 4115.35 of the Revised Code, or required to be purchased from a qualified nonprofit agency under sections 125.60 to 125.6012 of the Revised Code, the village administrator shall make a written contract with the lowest and best bidder after advertisement for not less than two nor more than four consecutive weeks in a newspaper of general circulation within the village or as provided in section 7.16 of the Revised Code. The bids shall be opened and shall be publicly read by the village administrator or a person designated by the village administrator at the time, date, and place as specified in the advertisement to bidders or specifications. The time, date, and place of bid openings may be extended to a later date by the village administrator, provided that written or oral notice of the change shall be given to all persons who have received or requested specifications no later than ninety-six hours prior to the original time and date fixed for the opening. All contracts shall be executed in the name of the village and signed on its behalf by the village administrator and the clerk.

The legislative authority of a village may provide, by ordinance, for central purchasing for all offices, departments, divisions, boards, and commissions of the village, under the direction of the village administrator, who shall make contracts, purchase supplies or materials, and provide labor for any work of the village in the manner provided by this section.
