How HSP GRUPPE builds AI capabilities for tax advisory

HSP GRUPPE, a network of tax advisory and law firms, integrated ChatGPT Enterprise into its operations as an organizational transformation rather than just a software tool, embedding it across tax advisory, legal research, client communication, and financial analysis. The firm established governance structures, monthly learning forums, and standardized successful AI use cases into shared Agents (reusable AI workflows) like AI Client Communication and Booking Assistant, while ensuring that professional review and final responsibility always remain with qualified tax, legal, or accounting specialists. The approach reduced repetitive work and made best practices available across the entire firm network, allowing professionals to spend less time on preparation and more time on expert advice.
