Armstrong Transport Group (ATG) is a third-party logistics provider headquartered in Charlotte, NC. Founded in 2006, ATG has grown into a nationwide organization with more than 150 agent offices and 1,000 logistics professionals serving customers across the country.

We are looking for an LTL Invoice Resolution Specialist to join our growing Less-Than-Truckload team. This role will be responsible for researching and resolving carrier invoice discrepancies, billing exceptions, accessorial charges, and other LTL-related financial issues while supporting ATG agents, customers, carriers, and internal teams.

The ideal candidate is highly analytical, detail-oriented, persistent, and comfortable working through complex billing issues from identification through final resolution. This individual will work closely with carriers and internal stakeholders to protect invoice accuracy, reduce aging disputes, recover invalid charges, and improve the overall LTL billing experience.

Responsibilities

• Review LTL carrier invoices and identify discrepancies between quoted, contracted, and billed charges.
• Research and resolve billing exceptions including reweighs, reclasses, accessorials, duplicate charges, minimum charges, and other carrier adjustments.
• Validate carrier charges against pricing agreements, tariffs, shipment documentation, dimensions, weights, freight class, and applicable rules.
• Submit and manage carrier billing disputes through resolution, including supporting documentation, follow-up, escalation, and credit verification.
• Communicate directly with LTL carriers to challenge unsupported charges and obtain corrections, credits, or additional documentation.
• Partner with ATG agents, operations, pricing, billing, claims, and accounting teams to resolve invoice issues efficiently and accurately.
• Research shipment history, bills of lading, proofs of delivery, inspection reports, carrier notes, and other documentation needed to support dispute resolution.
• Track open disputes and aging items, maintain clear notes, and proactively follow up until each issue reaches final resolution.
• Help ensure customer billing remains accurate by identifying carrier-side errors before they impact customers whenever possible.
• Identify recurring billing trends, carrier behavior, or process gaps and escalate opportunities for broader corrective action.
• Maintain organized records of disputes, credits, approvals, and supporting documentation within ATG systems.
• Provide clear, timely updates to internal stakeholders regarding the status, financial impact, and resolution of invoice discrepancies.
• Support special projects, audits, and process improvements related to LTL billing accuracy and invoice resolution.

Requirements

• Transportation, logistics, billing, accounts payable, accounts receivable, or invoice-resolution experience required.
• Strong attention to detail and a high degree of accuracy when reviewing rates, charges, and shipment documentation.
• Strong analytical, investigative, and problem-solving skills.
• Ability to manage a high volume of open issues while prioritizing by urgency, financial impact, and aging.
• Strong written and verbal communication skills with the confidence to work directly with carriers and internal stakeholders.
• Ability to follow an issue from initial research through final resolution without losing ownership or follow-up.
• Comfort working with spreadsheets, transportation management systems, carrier portals, and standard business applications.
• Ability to work effectively both independently and as part of a cross-functional team.
• Position may be based in Atlanta, Charlotte, or Chicago, with remote candidates considered.

Preferred Qualifications

• 2-3+ years of professional transportation, logistics, freight billing, or invoice-resolution experience.
• Previous LTL billing or carrier invoice audit experience strongly preferred.
• Familiarity with LTL pricing, freight classification, NMFC, carrier rules tariffs, accessorial charges, reweighs, and reclasses.
• Experience researching and disputing carrier invoice adjustments or freight-bill exceptions.
• Working knowledge of Microsoft Excel and experience reviewing large volumes of transactional data.
• Bachelor's degree or equivalent combination of education and relevant professional experience.
• Demonstrated history of strong follow-through, organization, and professional communication.

What Success Looks Like
