Description We are looking for an Accounts Payable Manager to oversee end-to-end payables operations for a long-term contract opportunity based in McLean, Virginia. This role is ideal for someone who can bring structure to a largely manual environment, maintain strong vendor relationships, and ensure accurate invoice handling across purchase order and non-purchase order transactions.

- Manage vendor relationships by responding to inquiries, addressing payment discrepancies, and maintaining dependable communication with external partners.

- Oversee payment activities including check disbursements, automated clearing house transactions, and indirect payment processing.

- Perform vendor onboarding and update supplier records within the accounting system to support accurate and compliant payments.

- Work effectively in a highly manual processing environment, ensuring consistency and attention to detail despite system limitations.

- Monitor invoice exceptions and investigate issues to determine whether errors are caused by process gaps, data entry mistakes, or system-related problems.

- Support daily accounts payable operations within SAP S/4

HANA and help maintain accurate transaction flow across the platform. Requirements - Proven experience managing full-cycle accounts payable operations in a high-volume setting.

- Strong background in invoice coding, invoice review, and payment processing for both PO and non-PO transactions.

- Hands-on experience with vendor management, including supplier setup and issue resolution.

- Familiarity with check runs, ACH payments, and indirect payment processes.

- Working knowledge of SAP S/4

HANA, with the ability to troubleshoot transaction or workflow issues.
