Job description

If you thrive in a fast-paced legal or professional services environment and take pride in delivering accurate, timely billing support, this could be an excellent next step for you.

Our client, a well-established international law firm, is looking for a Billing Coordinator to join their Business Services function as part of a growing revenue team. You will support the business with the creation, review, and distribution of invoices, playing a key part in improving process efficiency, supporting accurate billing practices, and helping to optimise the firm's working capital.

This is a predominantly remote role, with just one day per week in the office, offering a strong work-life balance alongside meaningful, varied work.

What You'll Be Doing

• Liaise with clients to obtain matter or purchase order numbers where required, and collaborate with internal fee-earning teams to ensure invoices comply with external counsel guidelines.
• Act as a subject matter expert on the firm's practice management system, identifying opportunities to improve billing functionality and enhance internal processes.
• Provide ad hoc support to the wider Finance team as needed, and ensure WIP comments and matter forecasts are recorded accurately and promptly.
• Conduct regular WIP reviews with fee earners and Finance colleagues to identify matters ready for billing.
• Manage billing email inboxes, respond to queries in a timely and professional manner, and ensure escalations are handled through to resolution, including the management of disputed invoices.
• Implement process improvements for new and existing matters, and monitor changes to client invoicing requirements to support timely payment.
• Manage the revenue cycle for specified partners, overseeing work-in-progress (WIP) and handling the end-to-end production of legal bills, from initial creation through to client distribution.
• Support the business with complex billing requirements, including bill amendments, reversals, write-offs, and database updates.

What We're Looking For

• The ability to work both collaboratively within a team and independently with minimal supervision, with an analytical and logical approach and sound judgement.
• Proficiency in Microsoft Office applications.
• Commercial awareness and a strong team ethos, with a genuine commitment to delivering high-quality service.
• An excellent client service mindset, with a proactive, solutions-focused approach and clear, effective communication skills, both written and verbal.
• Previous experience in a billing role, ideally gained within a legal or professional services environment.
• High level of diligence and organisation, with strong attention to detail and the ability to manage multiple priorities and meet tight deadlines.

Nice to Have

• Experience using Aderant tools and automated billing workflows.

Why Join

Our client offers a collaborative, progressive working environment with a genuine commitment to supporting their people. They are proud of their open and progressive culture, and are committed to providing talented individuals with the opportunity to build rewarding careers. This role offers a predominantly remote working model (one day in the office per week), making it well suited to someone looking for flexibility alongside a substantive role within a respected international firm.
