Apps & Services in This Stack

Each category below shows the recommended app or service and alternatives. Click on any item to learn more.

BankingApp
€29

Why this choice

Qonto integrates seamlessly with e-commerce accounting tools like sevDesk and Billbee, enabling automatic transaction categorization and reconciliation for high-volume shops. Virtual cards are perfect for managing advertising spend across Google, Meta, and other platforms with separate budget controls. The clean API and transaction exports reduce the month-end reconciliation burden that comes with processing hundreds or thousands of orders.

When to switch

Traditional bank if you need credit lines for inventory financing.

Alternatives

Payments & BillingApp
1.8% + €0.25 per transaction

Why this choice

Mollie is built for European e-commerce with native support for local payment methods that German customers expect: Klarna for buy-now-pay-later, SOFORT for instant bank transfers, Giropay, and credit cards. The competitive transaction rates often beat Stripe for EU-focused shops, and the Shopify integration is seamless. Adding PayPal as an additional option captures customers who prefer its buyer protection, especially for first-time purchases.

When to switch

Add PayPal as additional option for customer trust. Stripe if you go more international.

E-Commerce FinanceApp
€9-79

Why this choice

Billbee serves as the operational hub for multi-channel e-commerce, synchronizing orders from Shopify, Amazon, eBay, and other marketplaces into one unified system. It automatically generates GoBD-compliant invoices with proper sequential numbering, handles shipping label creation, and exports clean data to your accounting software. For shops without production or complex inventory needs, Billbee provides 90% of ERP functionality at a fraction of the cost.

When to switch

Xentral if you need full ERP with production/inventory. Overkill for small shops.

Alternatives

AccountingApp
€17.90-47.90

Why this choice

sevDesk has stronger e-commerce DNA than lexoffice, with native connectors for Amazon, Shopify, and other platforms that handle high transaction volumes efficiently. The automatic matching of marketplace payouts to individual orders eliminates the reconciliation nightmare that plagues e-commerce accounting. The inventory valuation features help you understand true product margins, and the DATEV export keeps your Steuerberater happy.

When to switch

lexoffice if you prefer simpler UX and your Steuerberater prefers it.

Alternatives

Cash Flow & LiquidityApp
€49

Why this choice

E-commerce cash flow is uniquely challenging: you pay for inventory and advertising upfront, then wait for marketplace payouts that can take weeks. finban helps you visualize these timing gaps, plan inventory purchases around payment cycles, and avoid running out of cash during high-growth periods. The seasonal pattern analysis is particularly valuable for shops with holiday or event-driven sales spikes.

tax-advisorService
€200-400

Why this choice

EU VAT for e-commerce is notoriously complex, with OSS (One-Stop-Shop) simplifying cross-border B2C sales but still requiring expert configuration and ongoing compliance. Your Steuerberater must understand e-commerce-specific issues like marketplace VAT collection, reverse charge for B2B, and proper treatment of returns and refunds. They should also advise on inventory accounting methods and help optimize your tax position as you grow internationally.

About This Business Type

E-commerce in Germany means navigating the most demanding consumer protection rules in Europe while competing in a market that expects fast shipping, easy returns, and multiple payment options. The German consumer's favorite payment method—invoice (Kauf auf Rechnung)—adds cash flow complexity that you won't find in other markets. Your finance stack needs to handle this reality. Multi-channel is the norm. Most successful German e-commerce businesses sell through their own shop, Amazon, eBay, and potentially other marketplaces. Each channel has different fee structures, payout timing, and integration requirements. Your accounting needs to reconcile all of these into a coherent picture of your business. EU VAT adds another layer. Cross-border B2C sales require OSS (One-Stop-Shop) registration and reporting, or handling VAT in each destination country. For Amazon sellers, Pan-EU programs add even more complexity. Get this right from the start—VAT errors can be costly.

Common Challenges

  • Multi-channel sales reconciliation
  • German consumer payment preferences
  • EU VAT and OSS compliance
  • High return rates and costs
  • Cash flow with marketplace payouts

Compliance Requirements

  • Kauf auf Rechnung expectation
  • OSS for EU cross-border B2C
  • German consumer protection (Widerrufsrecht)
  • Marketplace fee structures
  • German shipping expectations (DHL, etc.)

Why This Stack Works

  • Multi-channel order aggregation
  • Payment method diversity support
  • Automatic marketplace reconciliation
  • EU VAT handling via OSS
  • E-commerce specific accounting

Frequently Asked Questions

What payment methods do German online shoppers expect?

Germans love Kauf auf Rechnung (invoice/pay later)—offer it via Klarna or PayPal. Also essential: PayPal, credit/debit cards, SOFORT/Giropay for direct bank transfers. Offer 4-5 options minimum. Mollie handles most of these well. Don't require credit cards only—you'll lose sales.

How do I handle EU VAT for my German online shop?

For B2C EU sales, register for OSS (One-Stop-Shop) at your German Finanzamt. Report all EU sales quarterly, pay VAT at destination rates, all through one German return. Above €10,000 EU sales, OSS is mandatory. Below, it's optional but often simpler than alternative approaches.

What tools manage multi-channel e-commerce in Germany?

Billbee is the standard for German e-commerce—connects Shopify, Amazon, eBay, and others. Creates proper invoices, manages inventory, handles shipping labels. Xentral is the step up for larger operations (full ERP). Both integrate with German accounting systems via DATEV or direct sync.

How do I handle returns in German e-commerce?

German law gives consumers 14-day return rights (Widerrufsrecht), no reason needed. Expect 20-40% return rates in fashion, 5-15% in other categories. Build return costs into your pricing. Use automated return labels. Your accounting should track returns and refunds clearly—they affect revenue and VAT.
