Sales tax is the United States’ tax on sales, and its particularity is that it is not national: it varies by state, county and even city. The obligation to collect it depends on “nexus”, the economic link your business has with each state (by sales volume or physical presence). Understanding in which states you have an obligation, at what rate, and configuring it correctly in your store is essential to operating without tax risk. It is one of the biggest differences from selling in Europe with VAT.
Expand Your Ecommerce
to the United States
The United States is the world’s largest ecommerce market and the expansion goal of countless international brands: an immense volume, a consumer used to buying online, and a strong appetite for brands with identity. But it is also one of the most competitive markets, with particularities of its own that catch out anyone who arrives unprepared, from state-by-state sales tax to the shipping expectations set by the Amazon standard.
At STRAT we help ecommerce brands expand to the United States, integrating paid media, email marketing and Shopify under a strategy adapted to the market’s demands.

Why it is worth selling in the United States
The United States is home to the largest ecommerce market on the planet, with a consumer who buys online with complete ease, a high average order value and an enormous openness to new brands. Product with a strong brand identity (fashion, beauty, gourmet food, design) has a distinctive appeal in a market that values the authentic and the premium, and international brands with a differentiated proposition are well received. On top of that, the payment, logistics and technology infrastructure is very mature, which makes it easier to operate once the particularities are resolved. It is a demanding and competitive market, but with a volume potential no other country matches.

Why expand to the United States with STRAT?

We are not a generalist agency that also dabbles in internationalisation. We work exclusively with ecommerce and have supported brands in their expansion to the United States, with real knowledge of its particularities: we know how to manage sales tax by state, compete in the world’s most expensive advertising market and adapt the buying experience to the demands of the US consumer.
We apply that experience with a team officially certified by Meta, Google, Shopify, Klaviyo and Omnisend, integrating acquisition, retention and technology into a single strategy adapted to the market. In a market this competitive and expensive, measuring every decision in POAS is not an option, it is the only way to scale without losing money.

Frequently Asked Questions
Not necessarily to start. Many brands begin the expansion via cross-border international shipping, which lets you validate the market with controlled investment. However, since the US consumer expects fast, cheap shipping (the Amazon standard), as volume grows it usually makes sense to consider local fulfilment (3PL) or storage in the country to improve times and costs. We help define the model according to your stage.
The United States is one of the most competitive and expensive advertising markets in the world, with acquisition costs among the highest anywhere. Competing requires a clear value proposition, very solid creatives and very fine profitability management measured in real POAS. It is not a market to enter without differentiation or margin control, but with the right strategy, its volume compensates for the higher acquisition cost.
The market is dominated by the credit card and digital wallets (Apple Pay, Google Pay, PayPal). On top of that, buy-now-pay-later (Affirm, Afterpay, Klarna) has very high adoption, especially at mid and high order values, because consumer credit is very normalised. Offering these methods, including instalment payment, helps maximise conversion and compete with the local consumer’s expectations.
Very high, set by the Amazon standard: the consumer expects fast and ideally free shipping, and easy, free returns. Competing with cross-border international shipping can be a challenge on times, which is why many brands consider local fulfilment as they grow. Shipping and returns policies must adapt to these expectations so as not to start at a disadvantage against local brands.
Usually not without adapting it. The United States requires a store in American English, with sales tax configured by state, the local payment methods, and an experience and policies adapted to the US consumer’s expectations. It is not just translating, it is adapting the tax, logistics and experience operations to the market. We get your Shopify store ready to meet everything the market demands.
