ADDISON Software and Service

What ADDISON Software and Service does

ADDISON Software and Service is a German tax, accounting, payroll, and business management software brand headquartered in Ludwigsburg and operated as the flagship product line of Wolters Kluwer Tax & Accounting Deutschland, itself part of publicly traded Dutch parent Wolters Kluwer N.V. (Euronext Amsterdam: WKL). Founded in 1996, the company delivers a comprehensive integrated suite — including the Komplettlösung variants for tax advisors, SMEs (Mittelstand), and craft/trade businesses (Handwerk), plus specialized modules for audit (Wirtschaftsprüfung), payroll (Lohn & Gehalt), document management (AKTE), agriculture (Agrosoft HANNIBAL with BMEL natural accounting), and new-practice enablement (Kanzleigründer). The platform is available as both on-premise licenses and ASP/cloud-hosted subscriptions, with GoBD-compliant cash register integration and AI-assisted document capture (KI-gestützte Belegerfassung) embedded in the ADDISON Direkt client collaboration workflow. Sub-brands SBS Software and Agrosoft HANNIBAL extend coverage to small business and agricultural segments respectively, while ADDISON Akademie generates professional services revenue through training and seminars.

The business operates on a subscription and license model — including perpetual licenses, recurring ASP/cloud subscriptions, and paid training — distributed primarily through 15 physical locations across Germany supported by regional sales centers (Vertriebszentren), an inside sales Info Line, and a certified OneClick Partner integration ecosystem. ADDISON claims 15% of all German annual financial statements are produced on Wolters Kluwer software, 2.5 million monthly payroll calculations in Germany, and reach into 46,000+ tax offices and 550,000 SMEs in Germany served through tax advisors. Go-to-market is enterprise field sales with channel/partner overlay, targeting the German Mittelstand, tax advisory firms, craft businesses, and agricultural enterprises — segments with high regulatory density (GoBD, BMEL, German tax law) that favor embedded, content-rich incumbents.
