It is also a member of the Crowe International network, which spans roughly 200 member firms and 752 offices across more than 130 countries.

C-CLERC delivers a tightly integrated suite of five core professional services: legal/contractual audit of annual and consolidated accounts under Luxembourg or IFRS standards; commissaire services for small Luxembourg companies; special legal control missions (mergers, demergers, conversions, contributions in kind, liquidations, agreed-upon procedures); internal control and audit evaluation including outsourced internal audit functions; and business advisory covering M&A diligence, restructurings, IPO preparation, management buyout support, and accounting expertise. There is no proprietary software, platform, or technology stack; service delivery is human-led, partner-driven, and fee-based.

The firm serves seven vertical segments — commercial and industrial companies, financial participation and financing companies, insurance and reinsurance, other financial sector professionals, offshore investment funds, securitization vehicles, and associations and foundations — pursuing both local Luxembourg clients and international mandates routed through the Crowe International network. Pricing is quote-based and not publicly disclosed. Go-to-market is primarily through direct partner-led B2B engagement, supported by a professional website, published transparency reports from 2016 through 2025, and contributed press articles.
