How HSP GRUPPE builds AI capabilities for tax advisory

HSP GRUPPE, a network of independent tax advisory, auditing, and law firms, along with Kanzleipakt, utilizes a shared ChatGPT Enterprise workspace across 81 organizational groups. Internal estimates suggest this AI integration could generate approximately 40,000 hours of additional annual capacity. This includes 28,000 hours for billable specialist work and 12,000 hours for administration and client service. Based on conservative hourly rates, HSP GRUPPE estimates a theoretical annual revenue potential of around €3.8 million, emphasizing that AI enhances professional effectiveness rather than replacing tax advisors.
