What Auditor does

Auditor is a private Central European tax, audit, and accounting professional services firm delivered through three legally independent sister entities operating in the Czech Republic, Slovakia, and Austria under the brands AUDITOR and Stöger & Partner. The Slovak primary entity is AUDITOR SK s. r. o., established in 1999, with a secondary Slovak entity Auditor Bratislava s. r. o.; both are private limited liability companies with no venture or institutional ownership disclosed. The firm is a member of UHY International, a London-headquartered network of independent accounting and consulting firms represented in 340 cities across 100 countries with more than 9,500 professionals, and operates nine offices across the three countries (Prague, Brno, Pelhřimov; Bratislava; Vienna and Horn).

The service portfolio comprises six core lines: Tax Consulting (Daňové poradenstvo), Financial Accounting (Finančné účtovníctvo), Personnel and Payroll Administration (Personálna a mzdová agenda), Business Consulting (Podnikové poradenstvo) including M&A and transfer pricing, International Consulting (Medzinárodné poradenstvo), and Audit Services. Ancillary offerings are a secure cloud client portal (cloud.auditor.eu) for encrypted document exchange and BMD accounting-software training under a "BMD digital expert" recognition. Underlying technology is a third-party BMD accounting platform used for client training; no proprietary software or AI capabilities are indicated.

The firm generates revenue through professional services fees billed on a project basis or under retainer arrangements to corporate clients, primarily medium-to-large businesses with cross-border or Central European operations requiring coordinated tax, payroll, statutory audit, and financial accounting services. Distribution is direct, B2B, sales-led, with international coverage delivered via the UHY network and sister offices rather than third-party resellers.
