Friendly initial consultation, quick onboarding and even faster response times! I’ve only been a client for a few months, and everything is already running smoothly. Thank you!
Switching to Spielmann was the best decision: Their prompt, personal availability and reliable, open communication delivered immediate benefits.

An office at Nordpark 1—what more could you ask for? I greatly value Marius and Florian’s expertise in e-commerce and accounting. Highly recommended!
Excellent bookkeeping 🙏🏼 I’ve worked with several tax advisors in the past. After generating several million euros in revenue and filing countless VAT returns, tax is finally starting to be enjoyable. Definitely the right place to go for anyone who has just made their first million and needs support with e-commerce, Pan-European FBA and Amazon. Excellent!

Our services for you
We take care of your accounting, taxes and strategy so that you can focus fully on growth.
.avif)
Financial accounting
Digital. Scalable. E-commerce-ready.
If your tax advisor does not understand your business, accounting becomes a bottleneck.
We provide clear figures, automated workflows and a financial structure that keeps pace with your growth.
- We record marketplace settlement reports (Amazon, Shopify, Klarna & others) accurately, correctly and completely.
- Automated interfaces, clear processes and dedicated contacts who are genuinely available.
- An e-commerce-optimised chart of accounts providing full visibility into cost of goods sold, cash flow and profit.
- Transparent pricing—with no additional charges for questions or phone calls.
Annual financial statements
On time. Accurate. Tax-efficient.
Late financial statements undermine the confidence of banks and investors—and often cost you real money.
We deliver accurate annual financial statements on time, optimised for tax efficiency and tailored to the specific requirements of the e-commerce sector.
- E-commerce expertise for your annual financial statements. We understand the pitfalls and account for them correctly.
- We discuss your expected profits and tax liability with you at an early stage, so you do not find out in March that you need to make an additional payment of 80k.
- Investment deductions, provisions and depreciation of low-value assets—we want you to pay only what you are actually required to pay.
Tax returns
OSS, PAN-EU, sales to third countries? We find the right solution for you.
Incorrect tax filings are a serious matter. In the worst case, they can result in additional tax payments, penalty interest and fines.
Did you know that under Section 370 AO (German Fiscal Code), understating tax by more than €50,000 can result in imprisonment, even if the sentence is suspended?
We make sure it never comes to that.
- Specialist expertise in Europe-wide services and distance selling.
- Do you import through Rotterdam, sell to France, hold stock in Poland and operate an online shop in Germany? We know when OSS or local VAT registration applies and how your transfers of own goods must be reported correctly.
- Has the tax office raised questions, launched an audit or identified discrepancies? We handle the communication.
Tax structuring
More growth, less tax—sustainably and legally.
Growth without a strategy is like accelerating with the handbrake on. We show you today how to structure your business for optimal tax efficiency.
- GmbH, UG, holding company or GmbH & Co. KG? We help you plan your choice of legal form strategically and draw on our practical experience to advise you when a change may be worthwhile.
- Protect your liquidity through targeted investments, lower advance tax payments and optimised withdrawals.
- Are you planning to scale quickly or sell your company in the future? We put the right structures in place now so that you do not have to restructure later.
Payroll accounting
On-time payroll. Satisfied employees. Stress-free and digital.
Incorrect or late payroll statements undermine trust—and, in some cases, can cost you good employees. Our digital processes keep everything running smoothly.
- Your team relies on you, so we make sure payroll is completed on time—even when public holidays or exceptional cases arise.
- The entire payroll process is handled digitally via DATEV. Social security authorities, the tax office and health insurance providers—all reports are submitted automatically and on time.
- Commission, remote-working allowances, benefits in kind and bonuses—we account for everything correctly, without you having to work through the tax rules yourself.
Your centre of expertise for
tax, finance & law

Here you will find answers to the most frequently asked questions about working with us, switching advisers and our services.
Typically within four weeks. Your time commitment: less than 30 minutes.
We handle communication with your current tax adviser and manage the entire transition without disruption.
Primarily via Slack, with a dedicated channel for your team, as well as by email and phone.
We generally respond to queries within a few hours.
Yes, this is our core business. We accurately process settlement reports, FBA fees, PPC costs, returns and storage costs.
As a tax advisory firm, we also handle OSS filings, international transfers of goods (recapitulative statements – ZM) and much more entirely in-house.
Yes, SPIELMANN Steuerberatung GmbH is a licensed tax consultancy firm registered with the Düsseldorf Chamber of Tax Advisers.
We provide financial accounting, payroll accounting, tax advisory services, annual financial statements and tax returns—all from a single provider.
- As soon as goods are stored abroad, this automatically triggers a VAT registration requirement in the country concerned. Marketplaces such as Amazon already report this information automatically to the German tax office under your tax number.
- If you store or have stored goods abroad without registering, this is a ticking time bomb. Please contact us immediately so that we can initiate the necessary registrations and filings without delay and help you avoid further problems.
In the worst-case scenario, this may result in a tax liability in the relevant EU country, including filing obligations, registration, local tax adviser fees and potentially penalties.
As soon as you make cross-border sales, your OSS reporting must be handled correctly. If any issues arise, contact us immediately.
In practice, we recommend this structure once annual profits reach approximately €100,000, or if an exit is planned or realistically foreseeable.
- The problems you already have will remain—and become more costly and risky.
- Outstanding items, incorrect inventory records, VAT errors and unclear financial figures.
- These issues will not improve over time, and if the German tax authorities discover them, you will have a problem. Those who act too late lose control—and often money as well.
- If you want to grow over the long term, it is worth setting everything up properly now rather than having to limit the damage later.
- Yes, especially if you feel that your current tax firm is no longer meeting your needs.
- Switching firms during the year is straightforward. We seamlessly take over the posting of your ongoing business transactions and ensure that your business can continue operating as usual.
- If deadlines are missed, documents go missing or you never know where you stand on tax matters, something is wrong.
- A good adviser ensures that you have no unnecessary stress with the German tax authorities, understand your figures and are free to focus on your business.
- If you regularly find yourself wondering whether everything is being handled properly, it probably is not.
That depends on your vision, sales channels and the scope of services you require.
After an initial consultation, we will prepare a tailored proposal. In just 15 minutes, you will gain clarity on whether we are the right fit.
