Sir Business Consulting Gmbh

What Sir Business Consulting Gmbh does

SIR business consulting GmbH is a German boutique consulting firm founded in 2012 by Prof. Dr. Johannes Wirth and joined in 2013 by Managing Partner Thomas Neis, headquartered in Dreieich-Buchschlag near Frankfurt. The firm specializes in Record-to-Report (R2R) process optimization for finance and accounting functions, delivering advisory and implementation services across the full R2R lifecycle — Record, Close, Consolidate, and Report — for German Mittelstand and large/multinational corporations primarily in the DACH region (Germany, Austria, Switzerland). Its core capability is deep, dual-domain expertise that bridges financial accounting (HGB and IFRS) with enterprise software implementation, distinguishing it from pure IT consultancies or pure accounting firms.

The firm's technology stack centers on two consolidation platform ecosystems — SAP (EC-CS, SEM-BCS, BCS/4HANA, and S/4HANA for Group Reporting) and CCH Tagetik (Wolters Kluwer) — supported by SAP Analytics Cloud, Microsoft Power BI, XLCubed, and Databricks. Differentiated offerings include the Synopse framework, a vendor-neutral comparative analysis of leading consolidation systems, and a portfolio of adjacent services covering intercompany reconciliation, ESG/sustainability reporting (CSRD, EU Taxonomy), tax technology (BEPS Pillar 2/CbCR), disclosure management, and software selection advisory. Core technology partnerships with SAP AG and CCH Tagetik are designated as strategic-tier mutual relationships, supplemented by minor alliances with Horváth, Rödl, drjve AG, and the Saarbrücker Institut für Rechnungslegung.

The business model is project-based professional services consulting, priced per engagement rather than via recurring SaaS. Go-to-market is enterprise field sales targeting CFO and finance/IT decision-makers, supported by content-led demand generation through webinars (SAP S/4HANA Group Reporting series, CCH Tagetik Masterclass), technical articles, and industry events. The firm is actively expanding via the announced July 2026 integration of Accuratus Business Consulting, the 2025 strategic partnership with Rödl, and ongoing hiring, while operating with a team of roughly 11–50 employees.
