Our passionate team emphasizes analysis, profitability, cash flow management, and lean operations, treating clients as true partners in their business success.

Job Overview We are seeking a detail-obsessed, experienced Accounts Payable Specialist for a temporary, part-time remote engagement dedicated to one of our aerospace manufacturing clients. In this role, you will manage a high-volume weekly AP processing cycle end-to-end — from purchase order matching and invoice coding in Xero to vendor payment processing through Plooto. Your precision, sound accounting judgment, and ability to follow strict SOPs will directly support the financial operations of a fast-growing client in an exciting industry.

Duties

• Process high volumes of vendor invoices weekly, matching against purchase orders and entering bills accurately in Xero
• Copy approved purchase orders to bills, confirm line-item details, and assign correct account codes and budget categories
• Apply careful judgment to distinguish capital asset expenditures from operating expenses
• Process vendor payments through Plooto, following payment sequencing and limit protocols
• Set up new vendors in Plooto including EMT configuration, security question creation, and phone verification logging
• Identify and flag duplicate invoices, uncategorized items, and billing discrepancies before processing
• Collect ACH details and W-9s from vendors and store documentation per firm SOPs
• Exclude and route invoices that belong in other payment systems (e.g., credit card charges, expense reports)
• Communicate with vendors to verify payment details and resolve billing issues
• Support month-end close activities related to accounts payable

Requirements

• 3+ years of of accounts payable experience in a high-volume environment
• Proficiency in Xero, including purchase orders, bills, and account coding
• Experience with Plooto or similar ACH/payment processing platforms preferred
• Strong understanding of purchase order workflows and PO-to-bill matching
• Working knowledge of asset vs. expense coding and capitalization policies
• Exceptional attention to detail as accuracy is non-negotiable in this role
• Ability to follow detailed SOPs precisely and work independently in a remote setting
• Excellent communication skills for vendor interactions and internal escalations

Join us to be part of a forward-thinking firm where your expertise drives operational excellence for clients doing extraordinary work. We value proactive professionals who thrive on accuracy, process discipline, and continuous improvement.
