Allen & Overy, a leading global law firm, faced a significant challenge in accurately billing time across different jurisdictions. This issue, common in global law firms, often results in work not being billed, leading to substantial revenue loss. Estimates suggest that a typical global law firm could lose millions of dollars due to this problem. 


The primary challenge for Allen & Overy was the lack of proper time billing for multi-jurisdictional teams. Due to ethical walls, crucial case data like client and matter numbers were often not shared across jurisdictions. Consequently, emails exchanged were not filed to the Document Management System (DMS), and manually added client/matter tags in email subject lines were frequently dropped. This resulted in the inability of teams from different jurisdictions to bill accurately for their work, leading to significant revenue loss.
