-Schedule resources to support service agreements, maintenance programs, and ongoing customer requirements.
-Coordinate and manage subcontractors and vendors, ensuring timely, high-quality completion of service work.
-Order, track, and coordinate parts and subcontractor resources through the company’s service platform.
-Review completed time-and-material service orders for scope, costs, accuracy, and completeness, and process invoices according to established billing procedures.
-Maintain accurate and comprehensive service documentation, records, work orders, and customer communications throughout the account lifecycle.
-Proactively communicate with customers following service completion to confirm satisfaction and ensure adherence to service expectations.
-Assist in coordinating security-related projects and service requests through each stage of completion, ensuring work is delivered within established time, budget, and quality standards.
-Generate and execute purchase orders, manage invoicing, and maintain team schedules.
-Provide weekly and monthly reporting to internal and external management and customers regarding service and project status.
-Support, prioritize, and coordinate activities and resources across multiple offices.
-Ensure all service activities are performed in accordance with established delivery policies, contractual requirements, and company standards.
