What is a Translation Management System (TMS)? Complete Guide

Quick Answer

A Translation Management System (TMS) is software that helps organizations manage the translation and localization of their content across multiple languages. It centralizes all translations in one place, enables collaboration between developers and translators, and automates repetitive localization tasks.

Definition

Translation Management System (TMS): A software platform designed to streamline the process of translating digital content (websites, applications, documentation) into multiple languages. A TMS typically includes features like translation memory, terminology management, workflow automation, and integrations with development tools.

What Does a TMS Do?

A translation management system performs these core functions:

Key Features of a TMS

1. Translation Memory (TM)

Translation memory stores previously translated segments for reuse. When a similar or identical string appears again, the TM suggests the existing translation.

Benefits:

2. Terminology Management (Glossary)

A glossary defines how specific terms should be translated in each language.

Example:

3. Workflow Automation

Automated workflows handle:

4. File Format Support

Modern TMS platforms support:

5. API & CLI Integration

Developer-focused TMS platforms provide:

6. Machine Translation Integration

Most TMS platforms integrate with machine translation services:

Who Uses a TMS?

TMS vs. Other Solutions

TMS vs. Spreadsheets

Verdict: Spreadsheets work for <100 strings. Beyond that, use a TMS.

TMS vs. CAT Tools

CAT (Computer-Assisted Translation) tools like SDL Trados or MemoQ are designed for professional translators. TMS platforms are designed for software teams.

TMS vs. DIY (JSON Files)

Managing translations yourself with JSON files:

Frequently Asked Questions

What does TMS stand for?

TMS stands for Translation Management System. It's software that helps manage the localization of digital content across multiple languages.

Is a TMS the same as Google Translate?

No. Google Translate is a machine translation service that converts text between languages. A TMS is a management platform that organizes translations, enables collaboration, and may use Google Translate as one of many translation options.

How much does a TMS cost?

TMS pricing varies widely:

Do I need a TMS for a small project?

For projects with <100 translatable strings, you might manage with JSON files. Beyond that, a TMS saves significant time and reduces errors.

Can a TMS translate automatically?

Yes. Most TMS platforms integrate machine translation (Google, DeepL) or AI translation (GPT-4, Claude). However, machine translations typically need human review for quality.

What's the difference between i18n and l10n?

A TMS primarily helps with l10n, though some (like IntlPull) also help with i18n through code transformation tools.

Summary

A Translation Management System (TMS) is essential software for any team localizing their applications. It centralizes translations, enables collaboration, automates workflows, and integrates with development tools.
