The top 9 translation companies: Which is the best for your business?

Need support from a translation company but not sure how to find the best fit for your needs? Check out our comparison of 7 of the best companies to help you!


Translation and localization are key components of the growth strategy for businesses that aim to reach a global audience.

However, translation has its challenges, such as getting the nuances of language right, which can be a difficult task. Simply deploying machine translation won’t cut it. In fact, a study by UCLA Medical Center reports that the accuracy of Google Translate across different languages varies from 55 to 94%.

This is where partnering with a professional translation company comes in—one that can provide software and services to help you maximize cost savings and minimize the time and energy necessary to deliver accurately translated content.

But with hundreds of language service providers and translation agencies out there, which should you choose? In this article, we'll guide you through the must-haves for your next translation vendor and highlight the top nine translation companies that stand out from the rest.

Must-haves for your translation vendor

Identifying a top-tier translation company is challenging. You need to navigate each potential provider, evaluate its offerings, and verify its claims to confirm if it truly serves your business’s current and future vision.

You can look for a comprehensive list of must-haves in our buyer’s guide to selecting a translation solution, but here’s a list of key factors to consider when selecting a translation vendor:

Offered translation services

A translation services provider should offer a comprehensive range of language solutions for all your needs. The services include legal translation, technical translation, and website translation, to name a few.

Tailored and localized content for specific regions achieves a 12-fold increase in engagement compared to content that is not localized. It’s important to check if the vendor offers localization services to help you adapt your content for different regions and cultures while keeping cultural nuances in mind. Localization doesn’t end with textual translations—remember to check for media localization capabilities such as voice-overs, dubbing, transcription, and subtitling for your audio-video content.

Another offering to watch out for is AI-driven translation, which leverages advanced algorithms to significantly increase speed and reduce costs while maintaining quality. AI translation combined with human oversight offers a balance between quality, cost, and speed. It can handle large volumes of text quickly and accurately, making it an attractive option for organizations that need to translate a high volume of content regularly.

Additionally, if your business needs it, look for interpretation services for conferences, meetings, and other live or in-person events to facilitate seamless communication with your customers, employees, or business partners in other countries. Check out our detailed resource to learn more about the subtle differences between translation, interpretation, and subtitling.

Lastly, confirm that your potential translation company supports a wide range of languages, has built-in quality assurance mechanisms, and provides rapid turnaround times to ensure your business operations run smoothly.

Integrations and technical capabilities

A translation project involves multiple stakeholders, such as marketing, sales, and customer support teams. Your translation services company should support several integrations to facilitate seamless collaboration.

This includes connecting with content management systems, customer relationship management software, and other relevant platforms to drive efficient workflow management and content distribution.

Leveraging AI in translation processes is crucial for efficiency and accuracy. AI-led translation services, in conjunction with expert translators, can expedite translations, incorporate brand terms, and ensure accurate translations.

Additionally, opt for a collaborative tool that organizes all your translation projects in a single place, such as a translation management system (TMS), and provides detailed analytics about translation quality and costs.

Native-speaking translators

Native speakers are essential for producing culturally sensitive, high-quality translations that help you overcome language barriers. Ensure that the professional translation services you choose employ native speakers or freelancers who possess subject matter expertise, have several years of experience in your industry, and understand the nuances of the target market and culture.

Track record of success

A company's track record of success is a testament to its quality and reliability. Look for case studies, testimonials, and reviews from previous clients to gauge the company's translation performance.

Consider if the translation company has experience working with similar customer profiles that your business caters to. For instance, if you often work with healthcare or life sciences institutes, ensure that your translation service provider has a proven track record of efficiently handling medical translations.

A company that’s been around for a long time or has generated the most revenue is not automatically the best, especially if it’s not accustomed to working with companies like yours. You can’t beat the expertise that comes from hands-on work with similar businesses.

Scalability and flexibility

Your business needs may change over time, so it's essential to choose a translation company that can scale with you. For instance, if you have plans to expand into China or create Spanish content, make sure your translation vendor has the capacity to handle large volumes of work in those languages and can adapt to your evolving content needs and deadlines.

Up-to-date certifications

Certifications such as ISO 17100 and ISO 9001 are essential for ensuring that your translation services provider meets industry standards. Look for a company that has up-to-date and relevant certifications and adheres to industry best practices.

How to choose the right translation company

The above are among the best translation agencies out there today. But that doesn’t mean you should pick one at random and expect quality results. Submitting a Request for Proposal (RFP), like our sample translation RFP, can help a potential vendor understand your goals and clarify any questions you have. Here are a handful of the most important questions to ask to make the right decision:

  • What is the vendor’s unique value proposition?
  • What products and services does the vendor offer? How do they align with your company’s needs?
  • Which of its customers have been most similar to your business?
  • What security measures does it have in place?

Remember: it’s not all about your current needs. You need a company that can adapt and grow with you as your needs evolve. This is one reason that a true full-service translation solution like Smartling is so valuable.

Scale your business with Smartling’s robust translation solutions

You can translate any type of content with Smartling’s TMS, Neural Machine Translation Hub, and expert human translators. And you can do so for a fraction of the cost—and a fraction of the time—it would take to handle translation manually.
