Title: Accounts Payable Manager
Location: Green River, WY
Key Responsibilities:
Lead, develop, and cross-train the accounts payable team (AP Accountant and AP Clerks) — set priorities, assign work, and ensure coverage across payment runs and month-end close.
Own the end-to-end AP cycle from invoice receipt through payment — coding, three-way match (PO, goods receipt, invoice), exception resolution, and posting.
Oversee payment runs across all methods (check, ACH, wire, and foreign/cross-border payments), confirming funding and proper authorization before release.
Own the AP month-end close — accruals, cutoff, and completeness of recorded liabilities — and meet all close-calendar deadlines for AP deliverables.
Own AP account and bank reconciliations, with documented support and a clearing plan for every reconciling item.
Govern the vendor master — vendor setup, verification, and changes — including independent verification of banking details to prevent payment fraud.
Administer vendor tax reporting and compliance — 1099 and foreign-vendor (1042/1042-S) reporting, W-9/W-8 collection, backup withholding, and TIN matching.
Administer unclaimed property (escheatment) — track stale-dated and uncashed payments and unresolved credit balances and report to the applicable states.
Own and operate key AP and disbursement controls — three-way match, approval routing, duplicate-payment prevention, and segregation of duties — and maintain control documentation for internal and external audit.
Define and report AP KPIs — invoice cycle time, on-time payment, aged/blocked invoices, duplicate-payment rate, and discount capture.
Drive AP process and system improvements, including future workflow and automation.
Compliance with Company Financial Standards, internal controls, and Sarbanes-Oxley requirements.

Process vendor invoices end to end — receipt, coding, three-way match, exception resolution, and posting.
Execute and validate payment runs across check, ACH, wire, and foreign/cross-border methods; confirm funding and review the payment proposal before release.
Prepare and review AP journal entries with a clear business purpose and supporting documentation.
Prepare AP accruals and cutoff entries and confirm completeness of recorded liabilities at month-end.
Reconcile AP-related balance sheet and bank accounts, with a documented clearing plan for each reconciling item.
Monitor AP aging and drive timely clearing of held items and open balances.
Coordinate with procurement and operations on PO, goods receipt, service entry, and invoice-receipt timing to ensure proper period cutoff.
Set up and verify vendors, independently confirming banking details before payment; maintain vendor data quality — legal-entity naming, tax documentation, payment terms, duplicate prevention, and periodic review of inactive vendors.
Coordinate the annual 1099 process and foreign-vendor 1042/1042-S reporting; maintain W-9/W-8 records, backup withholding, and TIN matching.
Track and report unclaimed property — stale-dated and uncashed payments and unresolved credit balances — to the applicable states.
Provide audit support: pull invoice and payment samples, reconcile testing populations, and respond to internal and external audit requests.
Track and report AP KPIs — invoice cycle time, on-time payment, aged/blocked invoices, duplicate-payment rate, and discount capture.
Maintain AP process documentation, SOPs, and desktop procedures.
Act as SAP power user for AP and payment-processing transactions and tables.
