A leading international law firm is seeking an experienced Legal Biller to join its dynamic London-based Finance team. This is a fantastic opportunity for a proactive and detail-oriented professional to take on a key role in a fast-paced, high-performing environment.

Working closely with another Legal Biller and the wider Accounts team, you will take shared ownership of client billing operations across the London office. This is a hands-on role, suited to someone who thrives on deadlines, enjoys improving processes, and can build strong relationships with internal and external stakeholders.

Key Responsibilities

• Prepare, review, and process high volumes of client invoices, including using tools like Pre-bill Viewer.
• Liaise with internal teams and external clients to ensure timely and accurate billing.
• Manage e-billing portals and work closely with the e-billing team to reconcile submissions.
• Maintain accurate and organised billing records, invoice folders, and related documentation.
• Handle billing queries efficiently and professionally.
• Produce regular and ad-hoc billing reports; proactively identify ways to streamline and automate reporting.
• Provide billing support during peak periods (e.g., Collection Drives in June and December).
• Support annual audits (Statutory, SRA, Internal).
• Provide cover during team absences or annual leave.
• Assist with special billing projects and other finance-related initiatives as needed.

What We’re Looking For

• Experience in legal billing - ideally within a law firm or professional services environment.
• Strong understanding of VAT, compliance requirements, and billing best practices.
• Familiarity with legal billing systems such as Aderant (or similar platforms).
• Excellent organisational skills and attention to detail, especially under pressure or tight deadlines.
• Strong communication skills - both written and verbal.
• Able to work independently, prioritise tasks effectively, and manage competing deadlines.
• A collaborative team player with a positive, solutions-focused mindset.
• A passion for improving processes and driving efficiency.
• E-billing and collections experience is beneficial but not essential.

Why Join?

• Competitive salary of £40,000 - £50,000 per year.
• Supportive, collaborative team culture.
• Exposure to high-quality international legal work.
• Opportunity to develop within a forward-thinking, process-driven finance environment.
• Hybrid working arrangements for work-life balance.
