TASCO Revision und Beratung

What TASCO Revision und Beratung does

TASCO Revision und Beratung GmbH is a privately held German internal-audit and consulting boutique headquartered in Wiesbaden, founded in 2002 and led by Sami Abbas and Fanny Schmitz-Ercan as Geschäftsführung. The firm provides independent audit and advisory services to enterprise clients across German-speaking markets, structured around core auditing lines (commercial auditing, IT auditing, branch/store auditing, and non-profit auditing), a shared-audit 'Poolkonzept' model, and standardized Prüfverfahren methodologies. On the consulting side, TASCO offers due diligence, quality assessment, corporate governance, fraud services, data protection and cyber security, NIS-2 compliance, HinSchG (Whistleblower Protection Act) implementation, and auditor training. The firm is certified under DIIR Revisionsstandard Nr. 3 with a 100% 'voll erfüllt' rating achieved in early 2024, and was recognized as a Top-Arbeitgeber Mittelstand in 2024.

The business operates on a professional-services revenue model with bespoke, engagement-based pricing that is not publicly disclosed, distributed through direct enterprise field sales rather than channel partners. Target segments include large enterprises (primary), financial institutions, non-profit organizations, and clients requiring specialized IT auditing. Marketing is limited to a corporate website (tasco-revision.de) plus LinkedIn and Xing profiles for DACH professional visibility. With only 9 employees, no external funding, no disclosed subsidiaries, and no M&A activity, TASCO is a tightly held boutique operating with founder/management ownership, leveraging its DIIR certification and standardized methodologies as the primary differentiators against larger Big-Four and mid-tier audit competitors in the DACH market.
