The role oversees the end-to-end billing process for both contract types, ensuring accurate and timely invoicing, effective accounts receivable management, and compliance with client requirements, while driving process improvements, reporting, and automation to support the firm’s growth, including its expansion into new global offices in Singapore and Canada.

Key Responsibilities 

• Own the firm’s collections process — proactively following up on outstanding invoices, resolving payment obstacles with clients, law firms, and external billing services, and using billing technology and automation to accelerate collections and reduce days sales outstanding (DSO). 

• Deliver clear, transparent reporting on receivables, collections status, and outstanding balances to firm leadership and client-facing teams, alongside broader billing, accounts receivable, client, and management reporting and client budget tracking. 

• Review, submit, and monitor monthly invoices — including LEDES and electronic billing submissions — for Time & Materials and fixed-fee engagements, preparing supporting documentation, securing invoice approvals, and promptly resolving rejections, reductions, and other billing issues. 

• Update matter and timekeeper rates and maintain accurate billing information, client billing guidelines, and agreements in applicable systems. 

• Manage billing appeals and disputes, researching issues and coordinating with internal stakeholders and clients to resolve them. 

• Support billing operations for the firm’s global offices, including multi-currency invoicing, foreign client billing requirements, and compliance with local regulatory and tax requirements. 

• Identify opportunities to improve billing workflows, automate processes, and increase operational efficiency, serving as a key resource for billing systems and technology initiatives and a key contributor to the firm’s billing automation agenda across the global firm. 

• Collaborate with the Accounting team to ensure accuracy and efficiency across billing and accounts receivable processes, and support special projects and ad hoc requests from firm management.

• Demonstrated collections experience is required, with a track record of resolving past-due balances and reducing outstanding accounts receivable. 

• Understanding of legal matter management, client billing guidelines, and LEDES billing requirements. 

• Global or multi-jurisdiction billing experience is a plus, particularly related to Keystone’s offices in Australia, India, and the UAE, or its expansion into Singapore and Canada. 

• Strong attention to detail and a high degree of accuracy when working with financial and billing data. 

• Excellent written and verbal communication skills, with the ability to communicate effectively with attorneys, clients, and internal teams. 

• Strong organizational and time-management skills, with the ability to prioritize multiple responsibilities and meet deadlines in a fast-paced environment. 

• Highly motivated and proactive self-starter who can work independently with minimal supervision while collaborating effectively as part of a team. 

• Intellectually curious and analytical, with strong critical-thinking and problem-solving skills; able to research billing issues, identify discrepancies, and develop practical solutions. 

• Proficiency in Microsoft Excel is required. 

• Technology-savvy, with an interest in supporting the firm’s billing automation agenda; knowledge of automation tools, including automated email workflows, macro builders, and Excel automation, is preferred.
