Seid ihr eine zugelassene Steuerberatungsgesellschaft?

Ja. Die SPIELMANN Steuerberatung GmbH ist eine zugelassene Steuerberatungsgesellschaft, eingetragen bei der Steuerberaterkammer Düsseldorf. Finanzbuchhaltung, Lohnbuchhaltung, Jahresabschluss und Steuererklärung bekommst du bei uns aus einer Hand.

Wie schnell kann ich wechseln?

Typischerweise innerhalb von 4 Wochen. Dein Aufwand: unter 30 Minuten. Wir übernehmen die Kommunikation mit deinem alten Steuerberater und den kompletten Übergang ohne Unterbrechung.

Könnt ihr Amazon FBA, PAN-EU und OSS vollständig abbilden?

Ja, das ist unser Kerngeschäft. Wir verarbeiten Settlement-Reports, FBA-Fees, PPC-Kosten, Retouren und Lagerkosten sauber. OSS-Meldungen und Verbringungen (ZM) betreuen wir vollständig selbst.

Macht ein Wechsel unterjährig Sinn?

Ja, vor allem wenn du merkst, dass du mit der alten Kanzlei nicht weiterkommst. Ein Wechsel mitten im Jahr ist unproblematisch, wir übernehmen die laufende Buchhaltung nahtlos.

Ab wann lohnt sich eine GmbH mit Holding im E-Commerce?

In der Praxis ab ca. 100.000 € Gewinn pro Jahr oder wenn ein Exit geplant oder absehbar ist. Wir planen die Struktur mit dir, bevor du später umbauen musst.

Muss mein Steuerberater in Köln sitzen?

Nein. Unser Büro ist am Nordpark in Mönchengladbach, rund 60 Kilometer von Köln, zugelassen sind wir bundesweit. Händler und Brands aus Köln betreuen wir komplett digital via Slack, genauso gut wie vor Ort.

Wie läuft die Kommunikation ab?

Primär via Slack mit eigenem Channel für dein Team, dazu E-Mail und Telefon. Rückfragen beantworten wir in Stunden, nicht Tagen.

Übernehmt ihr auch die Lohnbuchhaltung?

Ja. Die Lohnabrechnung läuft digital über DATEV, alle Meldungen gehen automatisch und pünktlich raus. Boni, Sachbezüge und Minijobs bilden wir korrekt ab.

E-commerce tax advisor for Cologne

Free & no obligation

15 minutes

No preparation required

200+ clients. 100% e-commerce focus on Amazon, Shopify, D2C and multichannel.

What local proximity delivers, and what it does not?

Whether your bookkeeping is right is not decided by the distance to your tax firm. What matters is whether Amazon, Shopify, Klarna and DATEV come together cleanly. That is exactly our job.

You stay in Cologne, we stay at the Nordpark

Your company stays in Cologne, we stay at the Nordpark in Mönchengladbach. In between there is a phone and a Slack channel where you get answers in hours instead of days. Switching to us changes nothing about your location, only about your numbers.

Amazon and Shopify payouts are not a standard case

Amazon and Shopify pay you one amount that contains fees, reserves and discounts. If you record that as a single entry, you never see what is left per order and, above all, not what is taxable. We break every payout down to the individual order.

What you really earn in Cologne

Revenue is not profit. Our e-commerce BWA shows you every month what is left for you in Cologne after FBA fees, PPC, returns and advertising costs. That way you know your tax burden early instead of finding out in March.

Tax advice for retailers and brands from Cologne

Financial accounting, payroll, annual financial statements and tax returns from a single source. All with one focus: Amazon, Shopify, D2C and multichannel. No tradespeople, no restaurants, no doctors.

1. Working together via Slack

You get a dedicated Slack channel for your team, plus email and phone. We answer questions in hours, not days. If you still want to drop by, you are at the Nordpark in about 50 minutes from Cologne.

2. 100% e-commerce

Shopify, Amazon, Klarna, inventory and DATEV come together with us, not just side by side. We handle OSS, PAN-EU and intra-EU stock transfers (EC Sales List) entirely ourselves. A warehouse in Poland or sales to France are everyday business for us.

Process Amazon settlement reports cleanly
Book FBA fees, PPC and returns correctly
Cost of goods sold and inventory plausible against Sellerboard and KLAR

Three routes, one difference

A firm around the corner, accounting software or an e-commerce tax firm? The difference is not distance. It is who really understands Amazon payouts, inventory and the annual financial statements.

Wait and see

Costs nothing at first, but number chaos gets more expensive every month.

General tax firm

Can do the bookkeeping, but often knows Amazon payouts, FBA fees and OSS only by hearsay.

SPIELMANN

Connects Shopify, Amazon and Klarna with DATEV and delivers a BWA with a real contribution margin every month.

Our network in Cologne

For audits we work with dhpg, which also has an office in Cologne, everything else runs at our office in Mönchengladbach, digitally via Slack. Lars Schultka of LOONARA says: „After several million euros in revenue and plenty of advance VAT payments, taxes are finally starting to be fun. For anyone who has just made their first million, this is the right place to go for e-commerce, PAN-EU and Amazon.“

An introductory call in 15 minutes, the switch in 4 weeks, your effort under 30 minutes. We collect the documents from your current tax advisor in Cologne. You do not have to come to Mönchengladbach for it.

Are you a licensed tax consultancy firm?

Yes. SPIELMANN Steuerberatung GmbH is a licensed tax consultancy firm, registered with the Düsseldorf Chamber of Tax Advisors. You get financial accounting, payroll, annual financial statements and tax returns from a single source.

How quickly can I switch?

Typically within 4 weeks. Your effort: under 30 minutes. We handle the communication with your previous tax advisor and the entire handover without interruption.

Can you fully handle Amazon FBA, PAN-EU and OSS?

Yes, that is our core business. We process settlement reports, FBA fees, PPC costs, returns and storage costs cleanly. We handle OSS returns and intra-EU stock transfers (EC Sales List) entirely ourselves.

Does switching mid-year make sense?

Yes, especially when you notice your old firm is not taking you any further. Switching mid-year is unproblematic, we take over your ongoing bookkeeping seamlessly.

From what point is a GmbH with a holding worth it in e-commerce?

In practice from around 100,000 € in annual profit, or when an exit is planned or foreseeable. We plan the structure with you before you have to rebuild it later.

Does my tax advisor have to be based in Cologne?

No. Our office is at the Nordpark in Mönchengladbach, about 60 kilometers from Cologne, and we are licensed nationwide. We look after retailers and brands from Cologne fully digitally via Slack, just as well as on site.

How does communication work?

Primarily via Slack with a dedicated channel for your team, plus email and phone. We answer questions in hours, not days.

Do you also handle payroll?

Yes. Payroll runs digitally through DATEV, all filings go out automatically and on time. We map bonuses, benefits in kind and mini-jobs correctly.

Technical Background: E-Commerce Tax Law Cologne

The key rules for online retailers, regardless of location.

Single-entry recording requirement, Section 146 (1) AO

Aggregated items from marketplace payouts are not sufficient. Each entry must be recorded individually, completely, correctly, in a timely manner, and in an orderly fashion, and kept traceable to the order.

GoBD, BMF letter of November 28, 2019

The version of July 14, 2025 applies. Audits examine the traceability of the data chain from marketplace to accounting entry, not the tax rate.

OSS and transfers of goods, Section 18j (4) UStG and Section 3 (1a) UStG

The OSS return must be filed with the Federal Central Tax Office within one month after quarter-end. Transfers of own goods to EU warehouses are not covered.
