What a translation company actually does
A translation company manages end-to-end multilingual projects. Beyond translating words, it clarifies requirements, assembles the right linguists, and applies workflows that fit your text type and risk level. For regulated or high-stakes content—legal, technical, medical—that structure protects your brand and reduces downstream errors.
Typical activities include scoping and file prep, terminology research, translation, editing, proofreading, desktop publishing, and final QA. Companies also maintain glossaries and style guides, so your messaging stays consistent across documents and markets. They coordinate formats (Word, InDesign, XML, software strings) and deliver ready-to-use outputs, not just raw text.
The most valuable companies operate as partners. They help you prioritize content, pick service levels, and plan releases. They advise when human-only workflows are essential and when technology (like translation memories) can safely reduce cost and time without diluting quality.
Why a translation company’s workflow matters
A reliable workflow is the difference between “good enough” and “right first time.” A mature provider uses layered review (translation → editing → proofreading), project management, and fit-for-purpose QA checks. That structure makes errors visible early and aligns the result with the brief. For an overview of the service scope and options, see M21Global’s translation services page.
Expect clear handoffs: scoped files, reference assets, and round-trip checks after layout. Expect risk-based controls: more scrutiny for contracts than for internal memos. Expect auditability: who did what, when, under which instructions. The result is predictable quality you can defend to stakeholders and regulators.
Quality standards you should ask about (ISO 17100 & TEP)
Quality is not a mystery; it’s a system. Ask providers how they meet recognized translation-industry standards. ISO 17100 focuses on resources, processes, and qualifications for translation services. It formalizes the idea that trained linguists, documented workflows, and traceable reviews are prerequisites for reliable outcomes. (If you want to see the standard itself, consult the official ISO catalogue.)
The TEP model—Translation, Editing, Proofreading—puts those ideas into everyday practice. Three distinct steps, ideally with at least two linguists, reduce blind spots and enforce consistency. When timelines or budgets are tight, a provider might adjust scope, but they should explain the trade-offs and recommend safeguards. A translation company that treats quality as a process, not a promise, will be transparent about this.
How a translation company differs from an agency or freelancer network
People often use “company” and “agency” as synonyms, yet the operating models vary. A translation company typically combines in-house leadership with a curated network and documented systems: onboarding criteria for linguists, non-disclosure controls, training, and continuous improvement.
By contrast, a loose freelancer marketplace can be economical for simple tasks but may lack governance. You get individual talent without coordinated QA, version control, or domain coverage across multiple languages. For teams that need dependable turnaround, strict confidentiality, or alignment with brand terminology, the company model offers more control and accountability.
How to evaluate providers: a practical framework
Selecting a provider is easier with a scorecard. Evaluate five areas:
- People & expertise. Native-level linguists in the target language, with proven subject-matter expertise. Ask for sample bios or project summaries relevant to your industry.
- Process & standards. Do they follow TEP? Are roles separated? How do they qualify editors? Can they map their process to ISO 17100 requirements?
- Technology & security. Translation memories, terminology tools, and secure file handling. Clarify whether sensitive content ever touches public MT systems.
- Quality evidence. Before-and-after samples, revision logs, or pilot results. Ask how they measure and correct recurring error types (terminology, formatting, numbers).
- Service & governance. Named project managers, SLAs, change control, and issue resolution paths. For common buyer questions, browse M21Global’s frequently asked questions.
Score candidates on each dimension. Run a small paid pilot with representative documents: one straightforward text and one complex, regulated piece. Review accuracy, formatting, terminology control, responsiveness, and adherence to instructions.
Price vs. value: how to balance scope, risk, and timelines
Low unit prices can backfire if rework hits your brand or schedule. Instead of comparing per-word rates alone, look at total cost of ownership: quality-related delays, reviewer time, and the risk of incorrect usage in the field. A provider that prevents a single critical error can save far more than the price difference with a bargain alternative.
Discuss service levels. For low-risk content, a streamlined workflow may be fine; for public-facing or legal content, insist on full TEP and pre-flight checks. Clarify turnaround expectations and surge capacity for releases. The best providers propose options—with pros, cons, and prices—so you can choose knowingly. When you’re ready, you can request a quote to compare scenarios for your files.
When to choose a specialized partner
If you operate in technical, legal, or compliance-heavy sectors, a specialized partner pays off. Look for demonstrable expertise: terminology management for engineering, sworn or certified options for legal use, or multilingual DTP for packaging and safety sheets.
Signals of maturity include documented improvement programs, translator training, and a “zero-defects” mindset. Ask how they prevent common failure modes: missing numbers in tables, inconsistent units, or truncated text in layouts. A specialized partner anticipates these issues and prevents them at scale.
FAQ
Q1. What should I include in a translation brief?
A strong brief sets up success. Start with purpose (who will read it and why), audience profile, and the target language variants (e.g., Portuguese for Portugal vs. Brazil). Share approved terminology, style guides, and any previous translations you like—or dislike—and explain why. Include file formats, required outputs, and constraints such as character limits or layout rules.
Next, define review expectations: who signs off internally, how feedback will be provided, and deadlines per milestone. Clarify confidentiality, data handling, and whether content may be processed with any machine translation tools. A clear brief lets your translation company tailor the workflow, select the right linguists, and avoid avoidable rework.
Q2. How do ISO 17100 and TEP reduce risk for regulated content?
Standards and structured workflows force consistency. ISO 17100 aligns people, processes, and qualifications so projects don’t depend on individual heroics. It emphasizes role separation and documented steps, which reduces the chance of silent errors. TEP adds practical guardrails by requiring multiple pairs of eyes and traceable edits before delivery.
For regulated content, that structure matters. Contracts, safety sheets, instructions for use, and HR policies must be accurate and defensible. With ISO-aligned processes and TEP, your provider can show who translated and reviewed each file, under what instructions, and how issues were resolved—useful evidence if an audit or dispute arises.
Q3. What’s the best way to compare quotes from different providers?
Normalize the scope first. Ensure each quote covers the same languages, volumes, file types, and service levels (e.g., translation-only vs. full TEP). Ask providers to describe their workflow, who performs editing and proofreading, and what is included in QA and DTP. Request sample deliverables or a short pilot that mirrors your real use case.
Then evaluate the “soft” factors: responsiveness, clarity of questions, and ability to anticipate risks. A slightly higher price from a company that catches issues early may be cheaper overall than a low quote that shifts the burden to your internal reviewers or causes release delays.
Q4. When is machine translation appropriate—and when is it not?
Machine translation can accelerate throughput and lower costs for high-volume, low-risk content, especially when combined with post-editing by skilled linguists. It can also help triage large repositories to identify what needs human-quality work. The key is governance: secure tools, proper filters for personal data, and clear guidance for post-editors.
Avoid MT for sensitive or nuanced materials where tone, context, or liability matter: legal documents, safety content, marketing copy, or anything that will be widely published. A seasoned provider will advise where MT fits your risk profile and where human-only workflows are the safer choice.
