Answering in a customer’s language can make support easier to use. It can also multiply a mistake: a wrong policy is still wrong after it has been translated.
Start with one reliable source of truth
Write the approved answer clearly before adapting it for other languages. Mark conditions that change by market, product or customer type. Prices, delivery options and legal wording may need a different answer in different places.
Test meaning, not just fluency
Choose common customer questions and ask a fluent reviewer to check the response. Include colloquial wording, spelling mistakes and follow-up questions. Pay particular attention to dates, money, measurements, return policies and any terms that have a specific meaning for your business.
Decide when to involve a person
If the source is unclear, the request is sensitive or the customer disputes the answer, route it to someone who can check. A smooth sentence should not be mistaken for a verified answer. Make sure the customer can ask for human support in the language they are using.
Begin with the languages your customers actually use, then expand after reviewing real conversations. That is more useful than advertising a large language count without knowing how well your own policies translate.
