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 Hamburg sitzen?

Nein. Unser Büro ist am Nordpark in Mönchengladbach, zugelassen sind wir bundesweit. Händler und Brands aus Hamburg 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 advice | Digital

Book an introductory call

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 Hamburg, we stay at the Nordpark

Your company stays in Hamburg, 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 Hamburg

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

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.

Technical Background: E-Commerce Tax Law Hamburg

The key rules for online retailers, regardless of location.

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

Entries must be recorded individually, completely, correctly, in a timely manner, and in an orderly fashion. A bulk payout must remain traceable down to the individual order.

GoBD, BMF letter of November 28, 2019

Tax audits follow the GoBD as amended July 14, 2025. The traceable data chain from marketplace to accounting entry is decisive.

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

The OSS return is due quarterly within one month. Intra-Community transfers are treated as supplies for consideration and are not covered by the OSS.
