What Does a Translation Company Really Do?

Let’s pause for a second. What do these companies actually do?

Here’s a simple breakdown of what the best translation services offer:

How Does a Translation Company Localize a Website?

Let’s say you want to translate your website into Spanish, German, and Japanese. What happens next?

1. Content Extraction: The provider scans your website and pulls out all text, headings, menus, product descriptions, everything that needs translation.
2. Glossary and Style Guide: You get a glossary of brand terms and tone guidelines so your voice stays consistent across every language.
3. Translation + Localization: Skilled translators (often native speakers) work on the content, adjusting slang, formatting, dates, currencies, and more to fit local expectations.
4. Integration: They’ll work with your CMS (like WordPress, Shopify, Webflow) or give you code-ready files to plug back in.
5. Testing: Before launch, they test the site in different languages to make sure it displays correctly, links work, and no content is missing.
6. Ongoing Updates: Whenever you add a new product or update content, they’ll help you keep all translations in sync, often using translation memory to save time and cost.

Why Tech-Enabled Translation Services Are the Future

Great translation isn’t just about language, it’s about speed, scalability, and cost-effectiveness. That’s why the best translation services mix human skill with smart tools.

What modern localization tech includes:

• Translation memory: Remembers previous phrases and avoids rework
• Glossary tools: Keeps terms consistent
• AI assistance: Handles repetitive text quickly (like product listings)
• Cloud-based platforms: Real-time collaboration and project tracking

This mix means:

• Faster turnaround
• Lower costs
• Higher accuracy
• Easier scaling across new markets

Final Thoughts: How to Choose the Best Translation Service for Your Business

There’s no “one-size-fits-all” answer. The best translation service depends on what you need.

Here’s a quick checklist to guide you:

1. Do they have experience in your industry?
2. Can they handle both translation and localization?
3. Do they offer tools or platforms to manage content?
4. Are they native speakers with subject-matter expertise?
5. Do they provide support beyond the first delivery?

Whether you’re a small online store or a global SaaS company, there’s a provider that fits your stage and scale.

So take your time, ask questions, and remember, translation is more than just words. It’s about connection.
