A.
No vendor shall enter into a contract with the Township or perform any work on behalf of the Township without first receiving authorization therefor in the form of a duly executed purchase order approved by the Township's Purchasing Agent and, if applicable, a resolution of the Township Council approving said contract. Any such authorization is expressly limited to the dollar figure indicated in the purchase order. Any increases in such authorization shall require a revised purchase order prior to the delivery of goods or the rendering of services.
B.
Any professional having executed a professional service contract shall, upon performing services totaling 70% of the amount of the purchase order, whether such services have been billed or not, provide the Township Purchasing Agent with an estimate as to whether additional funds are anticipated to be necessary to conclude the matter. If the professional determines in accordance with the provisions hereof that, having expended 70% of the amount authorized by the purchase order that the remaining 30% will be insufficient to complete the tasks set forth in this agreement, the professional shall immediately notify the Township Business Administrator and the Township Purchasing Agent requesting that the Township Council approve an amended professional service budget and resolution prior to the rendering of any additional services beyond the authorized amount. The Township shall not be responsible for the payment of any sums in excess of the original encumbered amount unless there has been compliance with this section.
