Localising an e-commerce business to the United States involves far more than simply arranging fulfillment. Adapted from J&J Global Fulfilment’s The Scale Up: Crossing the Pond event, this guide presents actionable insights from industry leaders on how to validate, set up, and succeed in the US market.
Why the US, and Why Now?
By Leo Eckley, Head of Strategic Accounts, J&J Global Fulfilment
The US represents one of the largest e-commerce economies globally, with customer spending power and average order values that significantly surpass domestic markets. As UK brands hit domestic growth ceilings, expansion overseas becomes essential.
The Urgent Case for Localisation
Cross-border shipping is becoming increasingly expensive, volatile, and complex due to regulatory and macroeconomic shifts:
- Elimination of De Minimis Exemptions: US regulatory changes have ended duty-free thresholds, exposing cross-border shipments to mandatory tariffs and processing fees.
- Rising Supply Chain Costs: Escalating carrier fees and international trade tariffs reduce margin predictability.
- Competitive Disadvantage: Direct shipping from abroad creates friction at checkout and delivery delays, placing non-local brands at a disadvantage against native US competitors.
Key Benefits of Holding Local Inventory
- Faster & Cheaper Delivery: Deliveries match domestic expectations.
- Checkout Transparency: Guarantees consistent landed pricing without unexpected cross-border fees.
- Tariff Mitigation: Bulk shipping reduces per-order cross-border expenses.
- Regulatory Protection: Safeguards your supply chain against sudden international shipping policy updates.
- Enhanced Inventory Efficiency: Improves stock movement and overall working capital flow.
Validating the Opportunity in the US
By Emre Cetin, Founder & Managing Partner, Metheus
Before committing substantial capital to inventory and fulfillment, brands must establish market demand through cheap, rapid testing.
The “Big 3” Validation Pillars
- Product-Market Fit: Distinguish between genuine repeat-customer demand and temporary marketing-driven momentum.
- Margin Compression: Account for dual margin pressure—rising landed costs, shipping, and higher US customer acquisition costs (CAC) against platform and channel fees.
- UK Credibility Does Not Travel: Domestic accolades, press, and brand virality rarely carry weight in the US market. Conversion relies on localized social proof, recent reviews, and explicit product value messaging.
The 3-Step Evidence Ladder
- Rung 1: Desk Signals (1 Week): Conduct low-cost research into US search volume, organic traffic, social listening, and competitor gaps.
- Rung 2: Paid Social Proxies (2–4 Weeks): Run targeted ad campaigns, landing pages, or waitlists to test US cost-per-click (CPC) and message resonance without holding local inventory.
- Rung 3: Limited Pilot (6–12 Weeks): Offer a narrow SKU set to a specific geographic region via direct-to-consumer (DTC) to confirm price acceptance and purchase intent.
Beachhead Entry & Pricing Strategy
Avoid broad national launches that dilute marketing spend. Instead, adopt a “beachhead strategy”—focusing on a single region or micro-region, core product lines, and one primary customer acquisition channel.
Pricing must be built from the ground up to absorb US operating costs, variable tariffs, and higher CAC, rather than converting UK RRPs at current exchange rates.
Operational, Legal & Tax Foundations
By Imran Gulamhuseinwala OBE, CEO, Tax Desk
Navigating the US requires adapting to a complex, multi-tiered regulatory system across 50 individual states and over 12,000 local sales tax jurisdictions.
Core Regulatory & Tax Realities
- No Federal Sales Tax: Indirect tax obligations arise purely at the state and local level.
- Sales Tax Nexus: Tax obligations are triggered through Physical Nexus (storing stock in a warehouse or 3PL creates immediate liability with no threshold) or Economic Nexus (exceeding state-specific revenue/transaction thresholds under South Dakota v. Wayfair).
- Net-of-Tax Pricing: Prices are displayed net of tax across sales channels, with variable local rates added dynamically at checkout.
- Litigation & Compliance Risk: Broader product liability rules require dedicated insurance coverage and US-specific governing law clauses in commercial contracts.
- Independent IP Registration: Domestic or European trademark protections do not extend to the US; early filings with the USPTO are required.
Executive Expansion Checklists
Operations Checklist
- Select the optimal operating structure (cross-border logistics vs. establishing a US entity like an LLC or C-Corp).
- Secure an Employer Identification Number (EIN) and set up a US business bank account.
- Establish payroll and hiring pathways (e.g., using a Professional Employer Organization / PEO).
- Perform pre-shipment customs, tariff classification, and valuation assessments.
- Integrate ERP, payment gateway, and inventory systems for unified financial tracking.
Legal Checklist
- Draft governing corporate documents (Articles of Incorporation, Bylaws, or Operating Agreements).
- Adapt UK terms and conditions to comply with US contract and consumer laws.
- File trademark protections directly with the USPTO.
- Review state-level privacy mandates (e.g., CCPA/CPRA in California, Virginia, Colorado).
- Obtain required sector-specific licenses or permits (FDA, CPSC, etc.).
Finance & Tax Checklist
- Conduct a state-by-state assessment of physical and economic sales tax nexus liabilities.
- Register for sales tax licenses and configure automated filing systems in applicable states.
- Confirm Marketplace Facilitator rules across third-party platforms versus direct webshop obligations.
- Reconcile financial reporting standards between UK GAAP / IFRS and US GAAP.
- Implement transfer pricing policies and foreign exchange (FX) risk management procedures.
From Forecast to Fulfilment
By Simon Dixon, Founder, Hatmill
Managing inventory across long-distance supply chains amplifies forecast errors. Supply chain strategy must focus on flexibility and decision-making speed when sales diverge from projections.
Structuring Your Fulfillment Network
- Single Distribution Center: Lowest setup costs and operational complexity, but results in slower delivery times to distant regions.
- Multiple Distribution Centers: Reduces shipping times and cost-to-deliver across regions, but increases inventory holding requirements by approximately 1.4x to maintain stock availability across locations.
- 3PL Partnership vs. Owned Facilities: Utilizing a 3PL provides rapid scalability and flexible cost structures, whereas owned facilities offer complete operational control once order volume justifies fixed capital investments.
Customer Acquisition & Experience
By Martijn Wiktor-Wagemans, Chief Strategy & Operating Officer, The Agency
Winning US shoppers requires a tailored channel and content strategy rather than a direct copy of domestic operations.
Beyond Amazon
While Amazon dominates US e-commerce, platforms like Walmart and Target are growing rapidly. Additionally, category-specific marketplaces (e.g., Chewy for pet supplies, Zappos for footwear) hold significant market share.
Content Transcreation
Simply copying UK listings leads to poor conversion. Content must undergo complete transcreation:
- Adapt language and terminology (e.g., “stroller” instead of “pram”, “color” instead of “colour”, ounces instead of milliliters).
- Align visual cues, lifestyle imagery, and branding to US consumer expectations.
- Ensure marketing claims adhere strictly to Federal Trade Commission (FTC) substantiation rules, as well as category regulations from the FDA or CPSC.
Shopper Visibility on Chat LLMs & AI Search
By Emma Jones, Founder, Amp’d
Consumer product discovery is shifting from traditional search engine result pages (SERPs) toward AI chat assistants like ChatGPT, Gemini, and Perplexity.
Building the AI “Evidence Chain”
AI commerce engines act as researcher, comparison engine, and advisor simultaneously. To ensure AI platforms recommend your products, establish a clear evidence chain:
- Canonical US Pages: Maintain distinct, accessible US product pages displaying USD prices, US stock availability, local measurements, delivery terms, and clear return policies.
- Structured Data: Implement comprehensive Schema markup (Product, Offer, Review) and complete every attribute field in marketplace feeds.
- Third-Party Proof: AI models verify product claims against external sources, including customer reviews, editorial mentions, and independent authority signals. Conflicting data across channels lowers AI recommendation confidence.
Expanding to the United States represents a transformative opportunity for scaling brands. By validating demand early, establishing robust legal and sales tax frameworks, and tailoring your customer experience to US expectations, you can build a sustainable, high-growth international business.
