Billing Specialist/Analyst – Microsoft Advertising (Contract)- 6 Months

Previous Microsoft Experience Required

Overview

Microsoft Advertising is seeking a highly detail-oriented Billing Specialist to support critical Accounts Receivable, Billing Operations, and Sales Enablement initiatives during the company's most important revenue-generating period of the year.
