Choosing a tech partner for US market entry: what to build first

A company entering the US needs six technical foundations before it spends on marketing: a US-ready website and pricing, privacy terms that match state law, compliant outbound email, honest review and AI claims, the tax forms US buyers will request, and answers to security questionnaires. Pick a tech partner that can build all six and own them as one program.

What does a company need technically to sell in the US?

Think of six layers. Each one has a job, a US-specific rule or expectation, and a deliverable you can check.

How should the website change for US buyers?

Localization is more than language. US buyers expect prices in dollars, American spelling, a US contact route, and plain refund and renewal terms. Show support hours in US time zones, and publish them honestly. If your team works from another time zone, say how fast a US customer gets a reply.

Do not stop at translation. Dates, units, phone formats, case studies, and examples need to feel local. We cover the distinction in website localization versus translation.

What privacy setup do you need?

The US has no single federal privacy statute, so you work from state laws and your contracts. California's regulations are the usual benchmark. They require a written contract with service providers that limits their use of personal information to specified business purposes and prohibits selling or sharing it. See the CPPA regulation text.

A workable starting kit has four parts.

1. A privacy notice that says what you collect, why, and with whom you share it.
2. A data map of every tool that receives personal data, including analytics, CRM, and AI services.
3. Processor terms with each vendor in that map.
4. A request process for access, deletion, and opt-out, with an owner and a deadline.

Which state laws apply to you depends on your size and data, so have US counsel confirm.

What are the rules for outbound email?

Sales teams entering the US often start with cold email. The FTC's CAN-SPAM guide says commercial messages must have accurate header information and a non-deceptive subject line, must identify as advertising, must include a valid physical postal address, and must offer a clear opt-out that you honor within 10 business days. Each violating email can draw a penalty of up to $53,088.

Build these into the sending system. An opt-out that depends on someone remembering will fail. Our post on cold outreach that books meetings covers messaging that earns replies without risking the domain.

What can you say in marketing about your product and customers?

Two FTC rules shape US marketing copy.

• AI and performance claims. The FTC has said there is no AI exemption from the laws it enforces. See its AI Comply announcement. Keep evidence for every measurable claim.
• Reviews and testimonials. The FTC rule on consumer reviews and testimonials, in effect since October 21, 2024, prohibits fake or false consumer reviews and testimonials, and bars incentives conditioned on reviews expressing a particular sentiment.

Collect real reviews, never write them yourself, and disclose material connections.

What tax paperwork will US customers ask for?

A US business paying a foreign company needs documentation to know what, if anything, to withhold. A foreign entity gives its US customer a Form W-8BEN-E, described on the IRS form page. The IRS instructions say that if you do not provide the form, the withholding agent may have to withhold at the 30% rate, the backup withholding rate, or another applicable rate. A US entity gives a Form W-9.

Prepare the form before the first invoice, so you never lose a deal to paperwork. Our post on W-8BEN-E and paying foreign software vendors shows what the US customer is checking. Your accountant should choose the right form and fill it in.

How should you answer US security questionnaires?

US mid-market and enterprise buyers send questionnaires before they sign. Common topics are access controls, encryption, incident response, sub-processors, and where data is stored. Write the answers once, keep them in a library, and update them each quarter. See security questionnaires for tech vendors. A company that answers in a day looks more reliable than one that answers in a month.

How do you choose the right partner?

Look for a partner that owns the loop from build to growth. Ask these questions.

1. Can they show shipped websites or products for foreign companies selling into the US?
2. Do they handle privacy setup, email systems, and tax paperwork prompts, or leave them to you?
3. Will one team run the website, the product setup, and the search and AI visibility work, so there are no gaps between vendors?
4. Do they overlap with your US customers' hours for support and demos?
5. Do they give you evidence for claims, not only promises?

Frequently asked questions

Build the foundations as one program

US market entry fails less often on product and more often on gaps: a missing privacy notice, an email system that ignores opt-outs, a form nobody prepared. One partner owning the website, product setup, and growth stack closes those gaps.
