American English translator

American English (en-US) is a variety of English that differs from British English (en-GB) in spelling (color/colour, organize/organise, center/centre), vocabulary (attorney/solicitor, elevator/lift, gasoline/petrol), date and unit notation (MM/DD/YYYY and imperial units) and legal and regulatory terminology (US law, SEC, FDA, US GAAP against UK/EU law). For a document intended for the US we hold consistently to the American variant; for the UK or EU we recommend British English.

An American English translation agency takes the coordination off your hands. We select a native en-US specialist translator who knows your sector and the American conventions, arrange certification where an authority requires it, and have the work checked by a second reviewer. You keep one point of contact for variant, terminology, scheduling and delivery, all under a single quote. A skilled freelance translator does excellent work too; the difference an agency adds is bringing those moving parts together so you are not managing them separately.

Yes. We translate contracts, SPAs and court documents into American English with terminology matched to US law, and align roles and office titles to the American legal system rather than British or EU equivalents. For SEC filings and a US GAAP context we work with translators experienced in American business and financial documentation. Our legal-translation page goes deeper into the approach. See [legal translation](/en/services/legal-translation/).

For official acceptance we provide certified translation: a signed and dated statement of accuracy from the translator or the agency. Where a body asks for more, this can be escalated to notarisation by a solicitor or notary public, or to an apostille or legalisation through the Foreign, Commonwealth and Development Office (FCDO). Note that American English is a localisation variant; documents destined for US authorities often follow separate routes (certified or notarised translation, and where needed an apostille via the competent Secretary of State). We confirm which route fits each document type in the quote.

Common fields for en-US are legal and corporate (US law, contracts, SEC filings), pharma and life sciences (FDA dossiers, clinical documentation, IFUs), technology and software (UI strings, manuals, product documentation) and marketing and ecommerce aimed at American consumers. Per document type we confirm the approach, the variant and any certification in the quote.

On working days you receive a reply within 1 hour. The lead time for the translation itself depends on document type, volume, language pair and any required certification, and is confirmed in the quote. For tight deadlines we confirm a workable rush schedule up front rather than promising a fixed turnaround.
