What Klein Consulting Könyvelőiroda does

Klein Consulting Könyvelőiroda Kft. is a Budapest-based accounting and tax advisory firm founded in 1996 by Managing Director Klein-Szedlár Rita, operating for 29 years from a single office at Alkotás utca 39/c in Budapest's XII district. The firm delivers outsourced accounting, payroll processing, tax advisory, year-end closing, management reporting, and company formation/termination services to Hungarian small and medium enterprises, with a dedicated service tier for companies whose annual revenue exceeds HUF 100 million and which require English-language support. A complementary offering addresses neglected or problematic accounting, NAV representation, and complex restructurings including simplified liquidation within 150 days.

The firm's service delivery is built on a cloud-based technology stack comprising the Számlázz.hu invoicing platform with automated NAV online data verification, the SMARTBooks cloud ERP/business management system, and direct bank feed integrations with MBH, OTP, Raiffeisen, K&H, UniCredit, and Wise. These integrations support paperless digital document processing, automated reconciliation, and an optional shared financial system that gives clients real-time visibility into their KPIs. The team of 7–10 staff includes a CEO with IFRS and tax advisor qualifications, senior and junior accountants, a chief accountant, tax advisors, economists, and administrative support.

Revenue is generated through custom modular service packages billed on a monthly cadence, where clients assemble only the services they require and pay exclusively for those used; pricing is not publicly disclosed and is determined through direct consultative engagement. Go-to-market is sales-led and direct, combining a website with quote-request forms, phone, and email (24-hour response guarantee) with inbound lead generation from a Hungarian-language tax and accounting blog, Facebook and LinkedIn presence, and an email newsletter offering free downloadable guides. No funding, M&A, or external capital is involved; ownership and management are founder-controlled.
