Job Description

What You'll Do

As a key member of our Finance team reporting to the Controller, you will own the day-to-day flow of accounts payable and accounts receivable, serving as a vital link between vendors, customers, and our operations floor.

Accounts Payable

• Receive, verify, and reconcile vendor invoices against purchase orders and receiving documentation so every payment goes out right the first time.
• Record payments, prepare payment runs, and keep vendor accounts accurate and current.
• Respond to vendor inquiries promptly and professionally, resolving billing discrepancies at the source.

Accounts Receivable

• Generate and issue customer invoices accurately and on schedule, keeping cash flowing into the business.
• Apply incoming payments, monitor outstanding balances, and assist with collections follow-up.
• Reconcile customer accounts and research payment discrepancies until the numbers tie out.

Reconciliation & Record-Keeping

• Reconcile assigned accounts and play a hands-on role in the month-end close.
• Maintain organized historical records, from check stubs to bank receipts, so answers are always a file away.
• Support the team with data entry and routine accounting tasks that keep the books clean.

Compliance & Controls

• Follow internal controls and company policies in every AP and AR activity.
• Protect the organization by keeping financial information strictly confidential.
• Support quarterly and year-end audits by providing requested documentation.

Cross-Functional Support

• Partner with purchasing, receiving, and operations to resolve invoice and payment questions.
• Take on ad hoc projects and analyses that stretch your skills beyond the day-to-day.
