How to Expand Your eCommerce Business to the US in 2025: A Seller's Practical Guide
The United States remains the world's most valuable eCommerce market, generating over $1.1 trillion in online retail sales in 2024. For international sellers — whether based in India, the UK, Southeast Asia, or Europe — it represents an enormous growth opportunity. But it's also one of the most competitive, legally complex, and operationally demanding markets to enter.
This guide cuts through the noise and gives you a clear, practical roadmap for expanding into the US market in 2025, covering entity setup, logistics, payments, compliance, and marketing — in that order.
Why the US Market Is Still the Biggest Prize in eCommerce
Beyond sheer size, the US offers several structural advantages for cross-border sellers:
- Amazon dominance: Amazon captures roughly 40% of US eCommerce, making it the logical first entry point for most sellers.
- High average order values: US consumers spend more per transaction than almost any other market.
- English-language content: If you already sell in the UK or Australia, much of your listing content transfers directly.
- Mature fulfilment infrastructure: Third-party logistics (3PL) networks are deep, competitive, and geographically distributed.
That said, entering without preparation is how sellers burn cash. Let's walk through the key pillars.
Step 1: Business Entity and Tax Setup
You do not need a US company to sell on Amazon US — but having one simplifies tax compliance, liability, and payments significantly. Most cross-border sellers opt for an LLC or C-Corp registered in a state like Delaware or Wyoming.
Once you're operational, you'll need to understand sales tax nexus. Since the 2018 South Dakota v. Wayfair ruling, states can require out-of-state sellers to collect sales tax if they exceed economic thresholds. Using Amazon FBA creates physical nexus in every state where Amazon stores your inventory — which is most of them.
Tools like Taxually can automate US sales tax registration and filing across multiple states, which is essential once your SKU count or revenue grows beyond a handful of states. Don't wait until you're facing back taxes and penalties to get compliant.
Step 2: Fulfilment Strategy — FBA, 3PL, or Hybrid
Your logistics model determines your delivery speed, cost structure, and scalability. Here's a quick comparison of the three main approaches:
| Model | Best For | Key Trade-off |
|---|---|---|
| Amazon FBA | Amazon-first sellers wanting Prime eligibility | High fees; limited control over inventory |
| 3PL (own warehouse) | Multi-channel sellers or those with high SKU count | More control; requires finding reliable partners |
| Hybrid (FBA + 3PL) | Sellers with both Amazon and DTC/other channels | Complexity; best overall flexibility |
For sellers going the 3PL route, ShipBob is one of the most established US-based fulfilment networks, with distributed warehouse locations across the country that enable 2-day delivery to most of the continental US. If you're also shipping across multiple channels including Shopify, their integrations are strong.
If you're already using a multi-channel selling tool, Linnworks can connect your inventory and order management across Amazon, Shopify, eBay, and other platforms — critical when you're managing US stock alongside stock in other regions.
Step 3: Carrier and Shipping Optimisation
Domestic US shipping is a cost centre that erodes margins quickly if left unmanaged. USPS, UPS, FedEx, and regional carriers all have different rate structures depending on parcel dimensions, weight, and destination zone.
ShippingEasy offers automated carrier rate comparison and discounted postage rates, which is particularly valuable for sellers managing high order volumes across multiple SKUs. Similarly, Shippo is a strong option for sellers who want a flexible, API-friendly multi-carrier shipping solution with access to negotiated rates.
Step 4: Intellectual Property and Brand Protection
The US has one of the strongest — and most litigated — IP environments in the world. Before you launch, you should:
- Register your trademark with the USPTO (United States Patent and Trademark Office)
- Enrol in Amazon Brand Registry using your US trademark
- Monitor for counterfeiters, hijackers, and unauthorised resellers from day one
If you don't yet have a registered trademark or need guidance on US IP strategy, Peretz Chesal & Herrmann, P.L. is a Miami-based IP law firm specialising in trademark registration and eCommerce brand protection — particularly useful for international sellers navigating US law for the first time.
Step 5: Multi-Channel Expansion Beyond Amazon
Amazon is the entry point, not the ceiling. The US market has mature channels in Walmart Marketplace, eBay, Etsy (for relevant categories), and a large DTC Shopify ecosystem. Diversifying early protects you from Amazon policy changes and builds a more defensible business.
Sellbrite is purpose-built for sellers who want to list and manage inventory across Amazon, Walmart, eBay, and Shopify from a single interface. If you're also connecting a Shopify store to your Amazon merchant account for fulfilment, Shipr automates that integration cleanly.
Step 6: Payments and Currency Management
Getting paid in USD and converting it efficiently is often an afterthought — until sellers realise how much they're losing in conversion fees and transfer delays.
WorldFirst allows sellers to hold USD balances, pay suppliers in their local currency, and convert at competitive rates — avoiding the double conversion penalty that eats into margins when Amazon pays out in USD and you're spending in GBP, INR, or EUR.
Payoneer is another well-established option, particularly popular with sellers across Asia and the Middle East who are receiving Amazon US payouts and need reliable cross-border payment infrastructure.
Step 7: Reviews, Feedback, and Social Proof
US consumers are review-driven. A new listing with fewer than 20 reviews will struggle to convert even with strong PPC. Building your review base early — compliantly — is not optional.
Highfive Reviews automates the process of requesting reviews and feedback from buyers within Amazon's terms of service, helping new US listings build social proof faster without manual follow-up.
Key Mistakes to Avoid When Entering the US
- Underestimating sales tax complexity — nexus rules vary by state and product category
- Using a single fulfilment location — US geography means East Coast-only fulfilment adds 3–5 days to West Coast deliveries
- Skipping trademark registration — US IP disputes are fast, expensive, and public
- Not localising listings — US consumers respond to specific language, sizing, and compliance labelling (FCC, CPSC, etc.)
- Ignoring return rates — US return expectations are high; build your policy and logistics accordingly
The Bottom Line
The US market rewards sellers who prepare properly. It punishes those who treat it as a simple copy-paste of their home market strategy. Get your legal, logistics, payments, and brand infrastructure in place before you scale ad spend — and you'll be positioned to build a genuinely durable US business in 2025.
