The Billing, Revenue and Cost Assurance Specialist ensures the accuracy, integrity, and efficiency of all billing and revenue streams across the Carrier business. The role is responsible for detecting and preventing revenue leakages, validating costs from upstream suppliers (FNOs, transit providers, data centre operators), and ensuring that customer billing reflects contracted terms.
