As a company grows, the demands on financial accounting, reporting, ownership structures, and tax planning increase. By the time a company enters a funding round or expands internationally, it needs reliable financial data and professional processes.

How can research reach the market faster? This question was the focus of the NXTGN CxO Dinner in October 2026.
About 40 guests from companies, universities, and institutions gathered to exchange ideas. Among them was our partner and startup expert Christoph Kalmbach.
Minister President Cem Özdemir emphasized the importance of closer collaboration between research, startups, companies, and investors to accelerate technology transfer in Baden-Württemberg.
For us, this exchange demonstrates that turning innovative ideas into successful companies requires not only capital and entrepreneurial courage but also robust financial and tax structures.

Ideally, even before the company is founded. The choice of legal structure, ownership structure, and tax issues can have long-term implications. As the company grows, professional financial accounting, reporting, and tax planning also become increasingly important.
We support startups with accounting, payroll, tax, auditing, and corporate finance. This includes digital financial accounting, payroll processing, annual financial statements, tax returns, holding structures, investor reporting, and the preparation of financing rounds and transactions.
A holding structure can offer tax and organizational advantages, particularly in the context of equity investments, planned financing rounds, or a future exit. Whether it makes sense depends on the company’s specific shareholder structure and its long-term business objectives.
Key issues include the structure of ownership, potential impacts on tax loss carryforwards, the treatment of financing elements, and employee stock ownership plans. These issues should be incorporated into the financing plan as early as possible.
For ESOP and VSOP models, particular attention must be paid to the contractual structure, tax treatment, payroll implications, and the consequences during financing rounds or an exit. The PKF Wulf Group assists startups with the tax classification of employee stock plans and with aligning them with existing equity structures.
Reliable reporting begins with clearly defined financial processes, regular monthly closings, and a manageable set of relevant KPIs. These typically include liquidity, cash burn, runway, revenue trends, margins, and variances between actual and budgeted figures. The PKF Wulf Group supports startups in establishing accounting systems, cash flow planning, and investor reporting, and can further develop existing financial processes.
International tax issues should be reviewed before hiring the first foreign employee, establishing a foreign subsidiary, or developing cross-border sales and service relationships. Relevant issues may include, among others, value-added tax, permanent establishments, payroll, transfer pricing, and the financing of foreign companies. The PKF Wulf Group provides guidance on these matters in collaboration with specialists from the international PKF network.
A change may be advisable if the current advisory services are no longer keeping pace with the company’s growth. Typical triggers include an upcoming financing round, a lack of investor reporting, international expansion, more complex ownership structures, or a planned exit. The PKF Wulf Group can assist with taking over day-to-day support and facilitating a structured transition.
During the initial consultation, we discuss the business model, the company’s stage of development, the shareholder structure, current financial processes, and the next steps for growth. Based on this information, the PKF Wulf Group can determine which issues are relevant in the short term and which structures should be established to support the company’s future development.
