Senior Billing Specialist

Senior Billing Specialist

Location: Deer Park, NY
Salary: $80,000–$100,000
Type: Full-Time | On-Site

An established and growing project-based contractor is looking for an experienced Senior Billing Specialist to join its accounting team in Deer Park.

This is not a basic invoicing position. You will take ownership of complex project billing from initial project review through final invoice submission, working across construction and public-sector contracts where accuracy, documentation, and contract compliance are critical.

The business works extensively across government, municipal, institutional, and commercial projects, including work with New York City agencies.

Why Apply?

• $80,000–$100,000 base salary

• Join an established and growing project-based business

• Take ownership of complex billing rather than simply processing invoices

• Exposure to significant municipal and government contracts

• Opportunity to improve processes and help develop the billing function

• Long-term opportunity to mentor and support additional billing team members

• Medical, dental and vision coverage

• 401(k) with company match

• Paid vacation, sick and personal time

The Role

You will independently manage billing across multiple projects and customers, including:

• Progress, milestone, contract, T&M and change-order billing

• Reviewing contracts, purchase orders and schedules of values

• Preparing and submitting project invoices from start to finish

• Reviewing labor, materials, project costs and approved change orders

• Preparing supporting documentation for government and municipal billing

• Prevailing wage and certified payroll documentation

• Timesheets, sign-in/sign-out records and other contract-specific backup

• Working with Project Managers and Sales to resolve missing or incorrect information

• Investigating rejected invoices and coordinating resubmissions

• Monitoring billing schedules and customer deadlines

• Supporting month-end and project closeout billing

• Improving billing controls, procedures and documentation

• Becoming a resource and mentor for other members of the billing team

What We’re Looking For

• 5+ years of hands-on project or construction billing experience

• Personally responsible for preparing, reviewing and submitting invoices

• Strong understanding of progress billing, contract billing, T&M, change orders and retainage

• Experience interpreting contracts and customer-specific billing requirements

• Construction, electrical, low-voltage, HVAC, engineering or a similar project-based background

• Government, municipal, public works or NYC agency billing experience strongly preferred

• Experience with prevailing wage and/or certified payroll highly desirable

• Strong Excel and ERP/accounting-system skills

• Excellent attention to detail and ability to manage multiple billing deadlines

Experience with NYC agency contracts, public works billing, certified payroll or prevailing wage projects would be particularly valuable.
