FINANCIAL FOUNDATION

You can't scale a U.S. business with a European bank account. Build real banking.

You need a U.S. bank account to take customer payments, pay employees, and conduct business. We help you set up business banking, payment processing, invoicing, and tax compliance—the operational plumbing that lets money flow in and out correctly.

THE PROBLEM

Your Banking Infrastructure Is Costing You Money and Risk

Taking payments through the wrong account. You're accepting U.S. customer payments through a personal German bank account or Revolut. Problems: customers are confused (why a European account?), you're losing 3-5% on currency conversion (€18K-30K/year on €50K MRR), tax authorities get confused (personal or business income?), payment settlement is slow (3-5 days).

No real U.S. business account. You haven't opened a U.S. bank account because you thought you needed an SSN (you don't, you need an EIN) or thought it was complicated (it's actually easy). You're still moving money through personal or European accounts.

Tax chaos. You don't know your sales tax liability. The U.S. has federal (none), state (0-10%), county, and local taxes. You don't know which states you owe tax in, what the rates are, or when to file. Result: unpaid tax liability €5K-50K, penalties and interest.

72% of DACH founders spend 10+ hours/month on payment reconciliation due to ad-hoc banking

Currency conversion losses: 3-5% of revenue (€18K-30K/year on €50K MRR)

Tax liability unknown: 55% of DACH founders haven't addressed sales tax compliance

Time waste: with proper infrastructure, accounting drops from 10 hours to 1-2 hours/month

WHY IT MATTERS

The Financial Impact of Professional Banking

€18K-30K/Year in Currency Savings

Proper U.S. banking eliminates 3-5% currency conversion losses. On €50K MRR, that's €18K-30K annually. Use a U.S. account, see immediate savings.

Investor-Ready Financials

Auto-synced accounting means clean financial statements for due diligence. No scrambling to reconcile months of chaos. VCs see a professional financial foundation.

Compliance & Risk Reduction

Sales tax compliance eliminates €5K-50K in potential back-tax liability. TaxJar handles filing, so you're never late. Insurance: costs €0, eliminates €100K+ risk.

Time Reclaimed

Automated accounting saves 8-10 hours/month. That's 1-2 hours/week you can spend on business instead of bookkeeping. Annual value: 480 hours at €100/hour = €48K.

COMMON QUESTIONS

Banking & Payments FAQ

Which bank should we use?

Mercury for SaaS startups. Modern, integrations, instant transfers, no minimums. Alternatives: Relay (similar), traditional banks (slower, more features). Mercury is optimal for DACH founders.

Do we need Stripe or can we use another processor?

Stripe is best for SaaS. 2.9% + €0.30, integrations, subscription billing. Switch if: volume is €10M+/year (fees matter), you need specialized features, or you want a dedicated account manager. For entering U.S.: use Stripe.

Do we need TaxJar or can we manage sales tax ourselves?

Manage manually if: revenue is low (€10K/month), only 1-2 states with nexus. Use TaxJar if: revenue is high (€20K+/month), 3+ states with nexus, you want automation. Cost: €100-500/month. Cost of screwing up: €5K-50K. Worth it.

What's nexus?

Nexus is significant presence in a state (office, employees, 5-10+ customers). You owe sales tax where you have nexus. For SaaS, most states don't require tax. Consult TaxJar or tax advisor.

Should we invoice in USD or the customer's local currency?

Invoice in customer's currency (EUR for EU, USD for US). Stripe handles conversion. Customer sees familiar number, you get USD in bank account. Less confusion around exchange rates.

How often should we do financial close?

Monthly: 1-2 hours, essential for clarity. Quarterly: review for trends. Annual: full tax preparation with accountant. Monthly close keeps you aware of cash flow and unit economics.
