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

How do you recognize a real e-commerce tax firm?

By the fact that you do not have to explain how Amazon settles. A real e-commerce tax firm knows settlement reports, FBA fees, Klarna and OSS from daily practice, not from a textbook.

It knows the data sources, not just the industry

Anyone serving e-commerce has to bring settlement reports, payment statements and stock movements together. An Amazon report alone is not bookkeeping.

It works on integrations, not on exports

Every manual Excel list is a place where errors arise. We connect Shopify, Amazon, Klarna, Stripe and GetMyInvoices directly. That keeps your bookkeeping effort under 45 minutes a month.

It takes responsibility, not just makes suggestions

Software makes booking suggestions, you have to decide. We stand behind valuation, deadlines and the annual financial statements. For that you have one fixed contact person.

What does SPIELMANN stand for in day-to-day work?

We serve D2C brands, Amazon and multichannel sellers as well as agencies, service providers and SaaS companies. One sector, many systems. No tradespeople, no restaurants, no doctors.

One sector, many systems

Amazon, Shopify, Klarna, PayPal, Stripe, 3PL warehouses and DATEV are part of our everyday work, not an exception. OSS, PAN-EU and intra-EU stock transfers just the same.

  • Shopify, Amazon and payments connected directly
  • E-commerce chart of accounts with a real contribution margin
  • Receipts via GetMyInvoices, Pleo or Moss

Availability that holds up day to day

Communication via Slack with a dedicated channel for your team, plus email and phone. Answers in hours, not days. Our office at the Nordpark is there for meetings, but it is not a requirement.

  • Dedicated Slack channel for your team
  • Answers in hours, not days
  • On-site meeting possible, not necessary

Everything from a single source

Financial accounting, payroll, annual financial statements, tax returns and tax structuring come from the same people. Whoever does the monthly bookkeeping also prepares the annual financial statements and knows your numbers.

  • One contact person for everything
  • Partner for M&A, exit and CFO services
  • Tax structuring before the back payment arrives

Status check in 15 minutes

We get to know you and your business. Software, sales channels, numbers. After that you know whether we are a good fit.

Wait and see, standard tax firm or SPIELMANN?

Wait and see, standard tax firm or e-commerce tax firm? The difference does not show when capturing receipts, it shows in numbers, deadlines and availability.

Wait and see

Costs nothing at first, but chaotic numbers get more expensive every month.

Standard 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 you a BWA with a real contribution margin every month.

A firm with a single industry focus

You do not have to explain again each time how Amazon settles or why a lump payout is not a booking. That is the difference specialization makes day to day.

Here is how it works: an introductory call in 15 minutes, a switch typically in 4 weeks, your effort under 30 minutes. 200+ clients already work with us this way.
