What FRTG does

FRTG Group is a German consortium of six auditing, tax, legal, insolvency, and business consulting firms operating under a common brand, headquartered in Düsseldorf. Founded in 1962 as Franz Rei\u00dfner Treuhandgesellschaft mbH, the group has expanded through organic growth and acquisitions (Essen 2014, Fromm 2024) into a multi-entity structure comprising FRTG Holding AG, three auditing and tax consulting limited companies, one further tax consulting entity, a legal partnership (Kleinheisterkamp Voigt Partnerschaft mbB), and the recently added Fromm Steuerberatungsgesellschaft. FRTG delivers personalized, tailor-made professional services from auditors, tax consultants, lawyers, and management consultants to national and international companies, entrepreneurs, associations, foundations, and private individuals across 17 locations in Germany, with international reach through the Russell Bedford global network.

The service portfolio spans six core lines: auditing (annual and consolidated financial statements under HGB/IFRS, sustainability reporting, supply chain due diligence audits), tax consulting (national and international tax advice, succession and inheritance planning, audit support), legal consulting (contract, corporate, labor, IT, IP, restructuring/insolvency law), insolvency consulting (pre-insolvency restructuring concepts, IDW S6/S11 reports, digital insolvency accounting via STP Winsolvenz and SAP), business consulting (due diligence, valuations, controlling, holding structures), and digital transformation consulting (DATEV Unternehmen online, paperless bookkeeping). A complementary sustainability reporting service supports CSRD and VSME compliance. The technology stack is built on standard German professional-services software — DATEV, SAP, and STP Winsolvenz — with no proprietary platform or AI components disclosed.

The business model is a B2B professional services fee structure on a sales-led, direct-engagement basis. Pricing is fully custom and not publicly disclosed; engagements are scoped per client and billed per service line. Customer acquisition is driven by professional reputation, referrals, the Russell Bedford international network, and thought leadership through monthly newsletters and company blog content. Ownership is family-controlled via FRTG Holding AG, with no external funding rounds and no public listing. The group is privately held, profitable in operation, and pursues expansion through a steady cadence of bolt-on acquisitions and service-line additions rather than venture-backed scale.
