• Review and interpret client contracts, pricing schedules, and amendments to ensure accurate billing setup and ongoing invoice integrity.
• Perform invoice trend analysis, variance research, and root-cause investigation to resolve discrepancies and prevent recurring issues.
• Validate billing inputs from business partners and upstream systems to confirm completeness, accuracy, and proper approvals before invoicing.
• Lead through influence by driving cooperation, alignment, and best practices among team members.
• Lead and coordinate billing process and system improvements, including documenting requirements, testing changes, and updating procedures.

• Bachelor's degree in Accounting, Finance, Business, or a related field, or equivalent combination of education, related experience and/or military experience.

Experience that would be great to have:

• Experience interpreting contract language and pricing terms and applying them to billing configurations or invoicing workflows.
