We’re looking for a detail-oriented Billing Assistant with prior law firm billing experience to keep the firm’s monthly billing cycle, insurance billing, payment tracking, and collections on schedule.

What You’ll Do

• Monthly billing cycle. Help prepare, review, finalize, and deliver invoices on schedule. Enter and maintain attorney-approved time entries in Timeslips, run billing reports and process approved corrections.


• Invoice accuracy. Review draft invoices for accuracy, completeness, formatting, and compliance with each client’s billing requirements, and resolve missing information or discrepancies with attorneys and billing staff.


• Insurance and EPLI billing. Prepare and submit invoices through carrier and third-party electronic billing portals, applying UTBMS task, activity, and expense codes and preparing LEDES files where required.


• Carrier guidelines. Review carrier billing guidelines, engagement requirements, and relevant policy provisions to identify submission requirements — and refer coverage or legal interpretation questions to the responsible attorney.


• Submission tracking. Complete required billing forms, confirm receipt and acceptance, resolve rejected invoices and technical issues, and keep carrier, claim, matter, and submission records organized.


• Disputes and appeals. Track carrier deductions, billing disputes, and appeal deadlines, and coordinate attorney review of responses and appeals.


• Collections. Monitor accounts receivable and outstanding invoices, send professional payment reminders, and follow up on payment discrepancies, failed payments and unresolved balances.


• Client communication. Answer client calls and emails about invoices, balances and payment procedures, and route substantive billing disputes to the right attorney or billing supervisor.


• Payments. Assist clients with LawPay payments and reconcile payment information against billing records.


• Billing department support. Keep billing records, status reports, and follow-up lists current, spot ways to improve accuracy and turnaround, and protect confidential client, financial, and firm information.

What You Bring

• Prior law firm billing experience — this one is required. You know how a law firm bills its clients and its insurance carriers.


• Hands-on proficiency with Sage Timeslips.


• Insurance defense billing experience, including EPLI matters, electronic billing portals, litigation billing codes, and carrier submission requirements.


• The ability to manage recurring monthly deadlines across multiple client and carrier requirements.


• Strong attention to detail, organization, and follow-through — and reliable attendance.


• Clear written and verbal communication, and a professional approach to client inquiries and collections.


• The ability to resolve routine billing issues independently and coordinate with attorneys and billing staff on the rest.

Nice to Have

• LawPay experience, including payment processing, transaction tracking, and reconciliation.


• Accounts receivable, collections follow-up, and insurance billing appeals.


• Proficiency with Excel and Outlook.
