Translation / Localization

Definition

A translation or localization agency converts a company's content into other languages: contracts, product interfaces, marketing campaigns, manuals, and regulated documents. Businesses hire them for the languages themselves, but also for project management across dozens of language pairs, subject matter review, and formal certification when a court, agency, or regulator requires it.

How they make money

Human translation is still priced per source word, typically 0.10 to 0.25 dollars depending on the language pair, subject difficulty, and how many review passes are included. Rare pairs and regulated content like medical or patent work sit at the top. The fastest growing line item is machine translation post editing, or MTPE, where AI produces the draft and a professional linguist corrects it, usually priced 40 to 60 percent below full human rates.

Beyond per word, agencies charge hourly for review, transcreation, and desktop publishing, flat fees for certified documents like birth certificates and diplomas, and per minute rates for subtitling and dubbing. One mechanism deserves attention: translation memory, the database of your previously translated sentences, earns discounts on repeated and similar text. Good agencies apply those discounts automatically and treat the memory as your property. That single clause can change your long run cost more than the headline rate.

What good ones have in common

Native speakers translating into their own language. The professional norm is that linguists translate into their mother tongue only, and live in a market where the language is current. Ask directly. Agencies that shrug at this are brokering whoever is cheapest.
Subject matter matching. A linguist who is excellent with marketing copy can be dangerous with a clinical protocol or a license agreement. Strong agencies assign by domain and can show credentials for legal, medical, and technical work.
A named review step. The standard professional workflow is translation, editing, and proofreading by separate people. Certification to ISO 17100 signals the process exists. A single pass at a full human price is a margin, not a method.
Your translation memory, in writing. Contracts should state that translation memories and glossaries built on your projects belong to you and are delivered on request. This keeps switching costs honest and your terminology consistent across vendors.
Straight answers about AI in the workflow. Every serious agency now uses machine translation somewhere. The good ones tell you exactly where, price it accordingly, and put a human of record on anything with legal or safety consequences.

Red flags

Human rates for machine output. The classic modern abuse: charge full per word pricing, run the text through an engine, lightly clean it. If a bid seems fast and cheap for the language pair, ask what workflow you are actually buying.
Every language, every subject, overnight. No agency employs deep expertise in everything. Firms claiming universal coverage are pure brokers, and quality then depends entirely on subcontractors you cannot see.
No questions about your content. Real linguists generate queries: ambiguous terms, missing context, audience decisions. An agency that never asks anything is not reading carefully, and the errors surface after publication.
Certified translation promised without credentials. Courts, immigration authorities, and regulators have specific requirements for certification and sworn translation. A vendor fuzzy on those requirements can get your filing rejected months later.

How the category is changing

This is one of the categories where AI displacement is not a forecast, it is the current price list. Neural and LLM based translation now produces usable drafts for major language pairs, and buyers know it, which is why pure human translation of routine business text is shrinking while MTPE becomes the default offer. Agencies have repriced accordingly, and any that pretend otherwise are competing against a free tab in their client's browser.

What holds value is shifting up the stack. High stakes content where errors carry legal, medical, or brand consequences still commands full human rates and expert review, because someone must be accountable for the output. Transcreation, adapting campaigns so the idea lands rather than the words, resists automation because it is writing, not conversion. And large buyers increasingly pay agencies to run the machinery itself: managing terminology, tuning engines on their own translation memory, scoring output quality, and deciding which content deserves which tier. The agencies growing in 2026 sell that judgment layer. The ones shrinking sell words by the pound.

Frequently asked questions

How much does professional translation cost per word?
Typical human rates run 0.10 to 0.25 dollars per source word, driven by language pair, subject difficulty, and review depth. Machine translation post editing, where AI drafts and a linguist corrects, usually costs 40 to 60 percent less. Certified personal documents are priced flat per page.
Is AI translation good enough for business use?
For internal documents and routine text in major languages, often yes with light review. For contracts, medical content, regulated filings, and marketing you actually care about, professional review remains the standard, because accountability and nuance are what you are buying.
What is the difference between translation and localization?
Translation converts text between languages. Localization adapts the whole experience: currencies, date formats, imagery, cultural references, and layout, so software or content feels native in the target market. Software and ecommerce projects almost always need localization, not just translation.
What is a certified translation and when do I need one?
It is a translation accompanied by a signed statement of accuracy from the translator or agency, required by courts, immigration authorities, universities, and many regulators. Requirements vary by institution, so a competent agency will ask exactly where the document is going before quoting.
How fast can an agency translate a document?
A professional linguist typically covers about 2,000 to 3,000 words per day with review adding time, so small documents return in one to three days. Large or multi language projects run on parallel teams, which is much of what the project management fee buys.

Translation firms increasingly ride global campaigns downstream from marketing agencies, and because their linguists are freelancers across dozens of countries, they run on contractor networks rather than the staffing agencies that supply most other service firms.
