Accounts Payable Operations Lead — Mechanical Services

A day in your role

Morning starts with a fresh inbox of vendor invoices. You triage what needs coding, match purchase orders to receipts, and flag anything that looks off—duplicates, price mismatches, or missing paperwork. By midday, you’ve reconciled statements from key vendors, requested any missing credits, and prepped the queue for the next scheduled payment run. In the afternoon, you’re tightening up the AP aging, clearing old items, documenting resolutions, and partnering with internal teams to close out open issues. Before you log off, you update digital records, confirm account balances, and lend a hand with office tasks that keep our fast-paced operation humming.
