Ready to lead a high-performing billing and collections team?

WilmerHale is looking for a Client Accounting Supervisor to take ownership of the billing and collections process for an assigned practice area. If you're a natural leader who thrives on accuracy, thrives in a fast-paced environment, and takes pride in developing talented people, this is your opportunity to make a real impact at one of the nation's premier law firms.

In this role, you'll supervise a team of Client Account Specialists, partner closely with the Client Account Manager, and serve as the go-to resource for billing attorneys and practice area leadership. You'll shape policy, drive performance, and help set the standard for high-quality service across the department.

 What you'll do

• Lead and develop a team. Supervise, coach, and direct the workflow of Client Account Specialists—setting clear expectations, fostering a positive, solution-oriented "can-do" culture, and supporting training, development, and consistent management practices.
• Own the numbers. Oversee pro forma generation, invoice preparation and revision, e-billing submissions, write-offs, client invoice delivery, and collection activities—ensuring everything is accurate, timely, and high-quality.
• Be the trusted point of contact. Serve as a primary resource for practice area management, staff, and billing attorneys, responding to inquiries on billing, collections, budgets, and reporting.
• Turn data into insight. Analyze attorney and department dashboards, spot trends, and communicate them promptly to key stakeholders. Review WIP, AR, rate renewals, and e-billing rejections, and advise leadership on the firm's revenue and cash cycle.
• Drive improvement. Identify opportunities to enhance reporting and processes, collaborate with finance counterparts, and help implement solutions that support firmwide initiatives.
• Solve the tough problems. Identify, escalate, and resolve complex billing and collections issues, and make recommendations that address both client needs and broader firmwide challenges.
• Safeguard quality and compliance. Ensure adherence to WilmerHale's billing and collections policies, client Outside Counsel Guidelines, accounting principles, and internal controls—while maintaining the integrity of accounting data.
• Keep the team running smoothly. Define backup processes and coverage, monitor performance against departmental metrics, and support corrective action and performance management as needed.

What you'll bring

• Leadership presence. Demonstrated supervisory capability, initiative, and accountability, with the ability to interact effectively with personnel at all levels and foster efficient, collaborative teamwork.
• Communication strength. Strong verbal and written skills, with the ability to convey information professionally through email, phone, and in-person interactions.
• Financial expertise. Solid knowledge of accounting policies and procedures and hands-on experience with accounting and collections software.
• Adaptability. The ability to prioritize competing responsibilities in a fast-paced environment and respond effectively to changing business needs.
• A forward-looking mindset. Openness to technological change—including a willingness to build comfort with generative AI tools as they become more integrated into the firm's practice—to support efficiency and innovation.
• Technical skills. Proficiency with Microsoft Office products.

• Minimum 5 years experience with billing, collections, or general finance support
• Minimum 3 years of management or supervisory experience preferred. Experience with law firm billing and collections software—including 3E and *Collect preferred
