Senior Legal Biller

Are you an experienced legal biller ready to step to a senior level?

Our client is an established international law firm with a substantial London office. They are seeking a Senior Legal Biller to join the Finance team and support a varied portfolio of complex client matters.

This is a strong progression opportunity for someone with solid billing experience who wants broader exposure to international work, a supportive team environment, and continued professional development.

The position follows a hybrid working model, combining time in the London office with home working. Standard full-time hours apply, and alternative working arrangements may be considered.

• Manage the team billing inbox and workflow tools, responding to queries and processing requests within agreed service levels.
• Review engagement terms and billing instructions to confirm that invoices meet relevant regulatory, tax, and client requirements.
• Support period-end billing activity, WIP administration, reporting, and the maintenance of clear internal records.
• Prepare proformas and invoices using the firm’s practice management system, checking payor information, tax treatment, currency, and matter‑specific instructions.
• Work with colleagues in other offices on cross‑border, multi‑matter, and multi‑currency billing.
• Resolve billing issues with lawyers, support teams, finance colleagues, and other relevant stakeholders.
• Process credit notes, invoice amendments, write‑offs, reversals, and reissues when required.
• Help deliver scheduled billing cycles and ensure agreed client arrangements are followed.
• Contribute to process improvements, maintain practical guidance, and provide cover across the team as needed.

• Strong written and verbal communication skills, with the confidence to work effectively with lawyers, assistants, finance colleagues, and senior stakeholders.
• Hands‑on experience of legal or professional‑services billing and invoice processing; familiarity with a recognised practice management system is essential.
• Excellent attention to detail, sound organisation, and the ability to manage competing deadlines.
• Experience of complex billing arrangements, which may include multiple currencies, payors, tax treatments, or international stakeholders.
• A practical understanding of engagement terms, client structures, and the regulatory considerations relevant to legal billing.
• Competence in Microsoft Office, particularly Word and Excel, for reporting and document preparation.

• Exposure to cross‑border or multi‑jurisdictional billing.
• Experience with electronic billing tools or managed client billing arrangements.
• Evidence of taking on greater responsibility within a billing team.

You will work in a collaborative finance function and build relationships with colleagues across legal, administrative, and operational teams.

The team supports the billing lifecycle from work‑in‑progress review through invoice production and follow‑up. It also provides useful financial information to help the business monitor performance and make informed decisions.

The organisation supports flexible ways of working and aims to balance business needs with individual circumstances.
