Your Marketing Agency Can't Register Your US Company

By the Seal Global Editorial Team · August 14, 2026

A European SaaS founder told us recently that his US launch was "already underway" — he had signed a six-month retainer with a go-to-market agency in New York. Two months and a healthy pipeline later, the first enterprise deal reached procurement and stopped dead. No US entity. No W-9. No US bank account to receive a wire. The campaign worked; the company simply could not accept the money. That is the failure mode this article exists to prevent, and it is why US market entry operations enablement belongs at the front of the plan, not behind it.

Can a Marketing or GTM Agency Register Your US Company?

No. A marketing or GTM agency cannot incorporate a US entity, act as registered agent, open a US business bank account, file state tax registrations, or run US payroll. Those functions are US market entry operations enablement — the legal, financial and HR infrastructure a foreign company must have before any commercial go-to-market programme can convert demand into collectable revenue.

This is not a criticism of agencies. Positioning, demand generation and sales enablement are real disciplines and most foreign entrants eventually need them. The error is one of sequence: buying demand generation before the company legally exists in the market it is generating demand in.

What a Marketing Agency Literally Cannot Do

The list below is not about capability or willingness. Each item is a regulated act that requires standing your agency does not have.

• Incorporate an entity. Formation is a filing with a Secretary of State, signed by an authorised incorporator or organiser.
• Act as registered agent. The agent must hold a physical street address in the state and accept service of process during business hours.
• Open a US business bank account. Banks run KYC and beneficial-ownership checks against the entity's owners and officers, not its vendors.
• File state tax registrations. Sales-and-use tax, withholding and unemployment insurance accounts are filed per state by the entity or an authorised agent.
• Run US payroll or act as employer of record. Employing people in the US requires registered tax accounts, workers' compensation cover and compliant onboarding.

Marketing agency vs. operations enablement partner

Why Skipping Operations Derails the GTM Plan Anyway

Demand you cannot fulfil is a liability. Enterprise procurement asks for a US contracting entity, a W-9 and US remittance details before a purchase order is issued. Consumers abandon carts that price in a foreign currency and ship from overseas. Contractors want to be paid from a US account. Every one of those frictions raises acquisition cost and lengthens the sales cycle, which is exactly what the marketing budget was supposed to fix.

There is a finance dimension too. Running early US revenue through the foreign parent creates permanent establishment risk, messy intercompany accounting and a restatement job later. It is far cheaper to set the accounting stack up correctly at the start — which is why our entry programmes pair the entity with outsourced accounting services and, where the parent needs board-level reporting, fractional CFO support.

The Correct First Ninety Days

1. Weeks 1–2: structure decision — LLC vs. C-Corp, state of incorporation, EOR vs. entity for first hires.
2. Weeks 2–4: incorporation, registered agent, EIN application, corporate records opened.
3. Weeks 4–7: bank onboarding, payment processing, accounting stack, first state tax registrations.
4. Weeks 6–10: payroll or EOR live, contractor agreements, insurance, and where relevant 3PL and customs setup.
5. Weeks 8–12: commercial launch — now the agency's work converts, because you can contract, invoice, ship and get paid.

Nothing here prevents brand and content work from running in parallel. The rule is narrower than it sounds: do not buy conversion-stage demand before the conversion machinery exists. Where teams need capacity fast without hiring, we fold in back-office outsourcing and US-hours customer support so the first customers are not served by a founder's inbox at 3am.

What To Ask Any Agency Pitching You US Expansion

• Who will be the registered agent, and in which state?
• Which entity will sign the customer contract on launch day?
• What bank account will receive the first payment, and is onboarding complete?
• Which state tax registrations are filed, and who monitors nexus thresholds?
• How is the first US employee paid, and under whose employer tax accounts?

If the answers are vague, the plan is a marketing plan wearing an expansion plan's clothes. Bring in an operations enablement partner for foreign companies first, then let the commercial team run at a market you can actually serve.
