Sharing customer communication and accounting classification agents in a network of firms

What was done

According to the account published by OpenAI on 7 August 2026, HSP GRUPPE, a network of tax firms, audit and legally independent lawyers, deployed ChatGPT Enterprise with a strong framework (monthly forums, internal confidentiality rules). Cases that work are then standardized into shared agents. OpenAI quotes in particular "AI Client Communication", which helps structure initial drafts in a more homogeneous and customer-oriented tone, and the " Booking Assistant SKR03 & SKR04", which helps prepare and classify certain writing questions; In all cases, professional decision-making remains human. The adoption figures published by OpenAI relate to the workspace shared with Kanzleipakt (81 groups): 84% of active users each week, more than 500,000 conversations between 1 February and 14 July 2026, and 98.6% of employees surveyed reporting increased productivity. An internal scenario, presented as conservative and theoretical, estimates about 40,000 hours of additional annual capacity and a turnover potential of approximately 3.8 million euros: this is not an realized income.
