Accounts Payable Specialist

Louth Callan (LCR EPC, LLC) is a full-service power infrastructure EPC contractor specializing in utility-scale solar, battery energy storage (BESS), substations, and high-voltage transmission. We self-perform the majority of our work with in-house engineering and construction capabilities, delivering tough projects East of the Mississippi that others won’t touch. We are scaling rapidly and building the financial foundation to support aggressive growth while maintaining discipline, accountability, and best-in-class project delivery.

Our core values guide how we operate:
Build Strong. Build Right. Build Ahead. People Power Performance. Work Hard, Live Well. Resilient Solutions. Innovative Results.

The Accounts Payable Specialist is a key member of the finance team responsible for accurate, timely, and controlled processing of vendor and subcontractor payables across our growing portfolio of EPC projects. This role owns the full AP cycle — from invoice intake and job-cost coding through matching, approvals, payment execution, and vendor relationship management — in a fast-paced construction environment.

You will partner closely with Project Managers, Project Controls, Procurement, and the Controller to ensure clean cost coding, proper documentation (including lien waivers), and disciplined cash outflow. Success requires strong attention to detail, construction AP knowledge, ownership of the payables pipeline, and the ability to keep vendors paid accurately while protecting the company.

Invoice Processing & Job Cost Coding

Receive, review, and process vendor and subcontractor invoices for accuracy, proper authorization, and complete supporting documentation.

Code invoices accurately to the correct project, cost code, and general ledger account in coordination with Project Managers and Project Controls.

Perform three-way matching (PO / receiving / invoice) where applicable and resolve discrepancies promptly.

Ensure change orders, back charges, and joint-check arrangements are properly reflected before payment.

Prepare and execute payment runs (check, ACH, wire) in accordance with payment terms, cash position, and approval matrix.

Track and manage subcontractor and vendor retainage; process retainage releases only when required documentation is complete.

Collect, review, and file unconditional and conditional lien waivers as a condition of payment; maintain organized waiver records.

Coordinate with Project Managers on disputed invoices, short pays, and payment holds related to performance or documentation issues.

Maintain clean vendor master data; set up new vendors with proper W-9, insurance, and banking information.

Respond to vendor inquiries professionally and resolve payment status questions in a timely manner.

Support internal controls around invoice approval, dual authorization for payments, and segregation of duties.

Assist with 1099 preparation, year-end reporting, and any audit or bonding-related AP documentation requests.

Prepare and maintain AP aging reports, open invoice lists by project, and payment forecasts for the Controller and leadership.

Reconcile the AP sub-ledger to the general ledger and assist with month-end close activities related to payables and accrued costs.

Help refine AP processes and documentation as the company scales; contribute to system improvements and data integrity.

Partner with Procurement and Project Controls to improve PO compliance, receiving processes, and cost coding accuracy at the source.
