Best translation company: Selection checklist

1. Industry Expertise – Look for demonstrated experience in your sector, not broad-stroke claims. Ask for case studies in your vertical and confirm whether linguists have domain-specific knowledge. 
2. Language Coverage – Your translation partner should cover both current and future language needs without outsourcing to anonymous subcontractors. Whether it’s Korean next quarter or Arabic today, delivery should be seamless and in-house. 
3. Scalability – If growth is on your roadmap, your translation agency should be able to scale with you. That means handling multi-language product launches, high-volume content, or localization rollouts without bottlenecks. 
4. Tool Integration – Modern translation agencies can plug directly into your CMS, code repository, or marketing stack. Look for native integrations and automation that reduce handovers instead of creating more file chasing. 
5. Full-Service Capabilities – From UI strings and SEO content to training videos and DTP-heavy brochures – your ideal translation partner should handle all content types under one roof, minimizing vendor coordination and quality risk. 
6. Quality Assurance – ISO certifications, native linguists, terminology management, and structured QA processes are must-haves. Ensure your translation agency’s quality workflows go beyond basic machine checks. 
7. Project Support – Dedicated project managers (ideally in your time zone) make all the difference. You want someone who knows your brand, anticipates needs, and proactively keeps localization on track.
