What You Actually Need to Start Selling in the U.S. (Entity, Banking, Payments)

You have a product that works. Your home market is growing. And the US represents the biggest eCommerce opportunity on the planet. So, you decide to start selling in the US. Then reality hits.

The guides you find online are either too vague or too focused on a single piece of the puzzle. Critical details on how entity setup, banking, payment processing, and compliance all interconnect are rarely explained. FT3 Pay helps cross-border businesses navigate exactly this complexity. If you want to sell in America from overseas, here is the complete picture of what you actually need.

Requirement 1: A US Legal Entity

Before you can open a bank account, sign a merchant agreement, or collect USD from American customers, you need a US legal entity. This is the foundation of compliance for foreign companies. Without it, the rest of your tech and financial stack simply cannot function.

Your two primary options for establishing a US business entity include:

Delaware C-Corp

Key Characteristics
Standard for venture-backed companies. Double taxation, but strong investor appeal and preferred by most institutional investors.
Best For
Ideal for: Companies raising US capital, pursuing venture funding, or planning long-term US corporate operations.

Wyoming or Delaware LLC

Key Characteristics
Pass-through taxation, simpler administration, fewer compliance requirements, and lower ongoing maintenance costs.
Best For
Ideal for: Lean operations, DTC brands, agencies, SaaS startups, and bootstrapped businesses focused on efficiency.

In addition to choosing an entity type, you will need an Employer Identification Number (EIN) from the IRS, a registered agent in your state of incorporation, and an operating agreement or corporate bylaws. The formation process typically takes one to three weeks.

Requirement 2: US Banking & Financial Infrastructure

With your entity formed, you need a robust corporate banking setup tailored for international companies. This is where many non-resident founders hit unexpected friction. Traditional US banks often require in-person visits, extensive documentation, and long onboarding timelines for foreign-owned entities.

To operate smoothly, you need at least two distinct financial capabilities:

  • A US Business Bank Account: For settlements, operational expenses, payroll, and treasury management.

  • A US Merchant Account: Built specifically for non-resident founders so you can accept card payments and settle funds domestically.

The merchant account piece is critical. Processing payments through a foreign merchant account means every US transaction is treated as cross-border, which lowers authorization rates and increases costs. A domestic US merchant account ensures your transactions are processed locally, the single most impactful change you can make for overall payment performance.

Requirement 3: Payment Processing That Actually Works

Payment processing for foreign sellers is not just about getting a checkout page live. It is about building a payment stack that maximizes revenue from day one. Understanding how to accept international payments on your website efficiently as international operations scale is the difference between a 70% authorization rate and a 95% one.

The domestic eCommerce payment setup that United States customers expect should include:

  • Local US acquiring through a domestic payment service provider (PSP).

  • Support for US consumer-preferred payment methods: Visa, Mastercard, Amex, Apple Pay, Google Pay, PayPal, and buy now, pay later (BNPL) options.

  • Smart routing via advanced payment orchestration and routing to direct transactions to the best-performing provider based on card type, transaction volume, and issuing bank.

  • PSP redundancy so a single provider outage does not take your revenue down to zero.

  • Advanced fraud-prevention tools calibrated specifically to US transaction patterns.

The right US payment gateway for global brands does not lock you into a single provider. It gives you the flexibility to connect multiple acquirers and PSPs through a single integration and optimize performance continuously via automated payment orchestration.

Requirement 4: Compliance & Tax Obligations

Compliance is the requirement most international brands underestimate. Cross-border compliance obligations in the US are complex because they vary heavily by state, industry, and business model.

Here is what you must address before your first sale:

Sales Tax (Nexus)
If you hit the economic nexus in a state — revenue or transaction thresholds — you must collect and remit sales tax, even without a physical presence.
PCI DSS Compliance
Any business that processes, stores, or transmits card data must comply with Payment Card Industry Data Security Standards.
Data Privacy
California (CCPA/CPRA), Virginia (VCDPA), and other states have strict consumer data privacy laws you must follow.
Industry Licensing
Certain sectors — fintech, health, and regulated goods — require specific federal or state licenses to operate.
OFAC / AML
Anti-money laundering requirements and sanctions screening apply to all businesses processing US financial transactions.

Getting compliance right from the start is not optional. Violations can result in steep fines, frozen merchant accounts, and forced market exit.

How FT3 Pay Brings It All Together

Most companies entering the US manage each requirement through a completely different vendor: one firm for entity formation, another for banking, a third for payment processing, and a fourth for compliance consulting. FT3 Pay eliminates this fragmentation.

We deliver an integrated infrastructure that connects entity setup guidance, banking introductions, compliant payment processing, and intelligent routing through a single platform with dedicated expert support. Our team includes fintech veterans and ex-operators who have scaled payment infrastructure for unicorns and enterprise brands across dozens of global markets.

Whether you are a European DTC brand, an Asian SaaS platform, or a Latin American marketplace, FT3 Pay gives you the infrastructure and strategy to launch in the US with confidence and scale efficiently.

The Strategic Path to Launch

One of the most common misconceptions is that you can figure out each requirement as you go. International brands often start with a quick-and-dirty cross-border payment setup, planning to add a US entity later and assuming compliance can wait. This approach creates compounding problems.

Cross-border authorization rates are structurally lower, and processing fees are significantly higher. When you finally try to transition to local acquiring, you often discover that your existing payment architecture does not cleanly support it. You end up having to rebuild your checkout system from scratch.

The smarter approach is to treat the entire stack as a single project from day one. Entity formation, banking, payment processing, compliance, and optimization should be planned together, even if they execute in sequence.

The US market is unforgiving of brands that show up unprepared. American consumers expect fast, familiar checkout experiences, localized payment methods, and seamless transactions. They have no shortage of alternatives if your checkout experience falls short. Getting the infrastructure right is about earning the trust of a market that has higher digital expectations than almost anywhere else in the world.

 

Frequently Asked Questions

1. Can I sell in the US without forming a US entity?

You can process cross-border transactions using your foreign entity, but authorization rates will be significantly lower, and fees will be higher. To access local acquiring, US banking, and domestic merchant accounts, a registered US entity is highly recommended.

2. Which state should I incorporate in?

Delaware is the most common choice for C-Corps due to its business-friendly corporate court system and appeal to investors. Wyoming is highly popular for LLCs due to lower annual maintenance fees and strong privacy protections.

3. How long does it take to open a US bank account as a non-resident?

Timelines vary by banking institution. Traditional corporate banks may take four to eight weeks and often require in-person verification. Working with an infrastructure partner like FT3 Pay, which has established banking relationships, can significantly compress this onboarding timeline.

4. What is the difference between a merchant account and a business bank account?

A business bank account holds your operational funds, payroll, and cash reserves. A merchant account is a specialized financial account that allows you to accept credit card payments and receive settlements from your payment service providers. You need both to operate seamlessly in the US.

5. Do I need to collect sales tax in every state?

No, you only collect sales tax in states where you have established an "economic nexus," which is typically triggered by exceeding a specific revenue or transaction threshold (e.g., $100,000 in sales or 200 separate transactions).
