Specializing in JTL, Shopify, and marketplace systems for e-commerce

As a boutique tax firm, we specialize in e-commerce companies, particularly those involved in:

  • JTL-based system landscapes
  • Shopify Stores
  • Marketplaces and platforms such as Amazon
  • Payment service providers such as PayPal and other payment providers

Personalized Support Despite Automation

Even though we rely on a high degree of automation, personalized support remains central:

  • Quick availability to answer questions and respond to crises
  • Timely analysis of your financial and tax situation
  • Reliable support during growth, restructuring, or special audits

Our experiences during the COVID-19 pandemic have shown just how valuable this combination of digital and in-person engagement is for clients and employees—and since then, we have continued to advance our digital transformation.

Location, Client Base, and Approach

Our clients are based in Germany and abroad. We provide digitally supported consulting services from our office in Düsseldorf—with a clear focus on:

  • Modern, efficient, and forward-looking tax and business consulting
  • E-Commerce and Platform Business Models
  • Sustainable, scalable digital processes

If you want to set up your e-commerce business in a way that’s professional, digital, and future-proof from a tax perspective, we are the right partner for you.

Our Consistent Focus on Digital Transformation

Since 2019, our business model has been consistently geared toward digital tax and business consulting. In terms of organization, processes, and technology, we operate with fully digital structures—not as an end in itself, but with a clear focus on measurable benefits for online retailers:

  • Digitized Financial and Payroll Accounting
  • Fast, structured processing of large volumes of data from online stores, marketplaces, and payment systems
  • Up-to-date, reliable figures for tax, banking, and management at all times

The result: higher-quality accounting, significantly faster access to financial data, and more efficient—and generally more cost-effective—tax audits. At the same time, your chances of securing loans improve, and you can respond more quickly to market and business trends—a decisive advantage in the dynamic e-commerce environment.

Even though I have managed to get the desired information from somewhere else, as it was quite urgent for me, I still apreciate very much being very professional of them and receiving a return call from the firm.
