J2B Steuerberatung

What J2B Steuerberatung does

J2B Steuerberatung is a privately held German tax advisory firm (Steuerberatungsgesellschaft) headquartered in Sandhausen, Baden-Württemberg, with a second office in Mannheim opened in 2019. The firm operates under the legal name Jakob Bentele Buffler Steuerberatungsgesellschaft mbH — a 2021 rebrand of the previously named Klinger & Kollegen — and is co-owned by its three managing directors, Oliver Jakob, Kai Bentele, and Robert Buffler. The firm employs 40+ trained staff across the two locations and traces operating history in Sandhausen back more than 45 years. Its services span the full SME tax compliance stack — income tax returns, digital financial accounting, payroll, annual financial statements, tax planning, and business succession advisory — alongside specialized E-commerce tax advisory backed by an IFU/ISM certification.

The firm's technical infrastructure is built entirely on the DATEV ecosystem rather than proprietary platforms: DATEV Unternehmen Online serves as the cloud accounting backbone with integrated online banking and document archiving; DATEV Meine Steuern provides clients a digital portal for uploading and categorizing tax documents; and Arbeitnehmer Online distributes payslips digitally. Client onboarding is delivered via the milia platform, new-employee HR data capture via fastdocs, and pricing transparency via a public Honorarrechner fee calculator. The firm operates a structured 8-step tax-advisor switchover process to capture clients from competitors and reduce migration friction.

J2B's go-to-market is sales-led with a digital layer: direct outreach via phone, email, and contact forms; free initial consultations; and a marketing presence spanning Facebook, Instagram, LinkedIn, YouTube, and SEO-optimized content. Customer segments include German SMEs (Mittelstand), E-commerce operators, family businesses in succession, startups at formation, and private individuals — predominantly SMB relationships across the Rhine-Neckar region. Revenue is generated through recurring professional service fees plus pass-through DATEV platform charges, with no public revenue disclosure and no external funding or institutional ownership.

Broad incumbents

• Baker Tilly Germany: Baker Tilly Germany is a mid-market audit, tax, and advisory firm serving German SMEs and family-owned businesses. Comparable to J2B in client segment and service breadth (tax compliance, succession, corporate restructuring), but at larger scale with national presence.
• Mazars GmbH & Co. KG: Mazars Germany provides tax, audit, and advisory services with strong SME and mid-market focus. Overlaps with J2B on tax compliance and advisory services, though operates as part of a global network at meaningfully larger scale.
• Rödl & Partner: Rödl & Partner is a large international German-origin advisory firm with strong tax, legal, and audit capabilities for Mittelstand companies. Highly comparable service mix to J2B (tax compliance, succession, cross-border tax), but at significantly larger scale and broader geographic reach.
• Ebner Stolz: Ebner Stolz is a major German mid-market advisory firm offering tax, audit, and consulting with strong SME/Mittelstand and family-business coverage. Overlaps with J2B on tax compliance, succession planning, and SME services, but operates as a much larger incumbent with a wider service portfolio and broader geographic footprint.
• Grant Thornton AG Wirtschaftsprüfungsgesellschaft: Grant Thornton Germany is a mid-market accounting and advisory network serving Mittelstand and family businesses. Overlaps with J2B across tax compliance, financial accounting, and advisory work, though at broader portfolio scale and with national/international reach.

Emerging players

• Taxfix GmbH: Taxfix is a Berlin-based consumer and freelancer tax-filing app that uses guided digital workflows to simplify German income tax returns. Adjacent to J2B's individual income tax service line, though Taxfix is purely consumer/PLG and does not serve corporate clients or complex advisory work.
• Accountable GmbH: Accountable is a digital-first German tax and accounting platform targeting freelancers, solo founders, and small businesses. Comparable to J2B in serving digital-savvy German SMBs with streamlined accounting/tax filings, though Accountable is software-led rather than partner-led and focuses on the lower end of the SMB market.

Direct peers

• ETL AG Steuerberatungsgesellschaft: ETL is Germany's largest tax advisory network with deep SME/Mittelstand focus and digital-enabled regional Kanzleien. Highly comparable to J2B in target client (German SMBs) and service breadth (tax compliance, payroll, succession, e-commerce advisory), though ETL operates at substantially larger network scale.
• Curacon GmbH Wirtschaftsprüfungsgesellschaft: Curacon is a mid-sized German tax, audit, and advisory firm focused on healthcare, social, and SME segments. Comparable to J2B in regional mid-market positioning, full-service tax and accounting offerings, and partner-led service model, with overlapping client profile of Mittelstand businesses.

Others

• DATEV eG: DATEV eG is the dominant German cooperative providing tax, accounting, and payroll software infrastructure to German Steuerberater and their clients. Not a competitor but the core technology partner for J2B; DATEV's Unternehmen Online, Meine Steuern, and Arbeitnehmer Online platforms are the backbone of J2B's digital service delivery and a defining feature of the firm.
