  • Publication number: 20240128115
    Abstract: Method and system that operates on a server include a time and expense management interface for capturing time and expense reporting. The time and expense reporting is for utility distribution systems, such as electrical power distribution and/or transmission systems, cellular, telecommunications, cable TV, water and sewer, natural gas, and others. These utility distribution systems include a large number of devices or objects that are distributed across a big geographic area. In one example, the authorization to submit the invoice for portions of the mobilization work order that have completed the approval process includes only authorization to submit the invoice for those portions of the mobilization work order i) not already paid or ii) that have been previously submitted and completed the approval process. The invention helps to document time and expense for government agencies, such as public utility commissions. This documentation maybe used with setting special charges on customer invoices.
