Why it matters
International clients often contact several businesses and choose the one that answers clearly in their language. For clinics, property, tourism and professional services, language can decide the sale before price is discussed.
Choose languages by evidence
Look at where your enquiries, website visitors and best clients come from. Support those languages properly before adding more. Three languages done well beat ten done badly.
Keep answers accurate in every language
- One source of truth: keep the knowledge base in one language and let the assistant answer in the customer's language, so facts never drift between versions.
- Fixed terms: list service names, prices, units and legal terms that must be translated consistently, or left untranslated.
- Native-speaker review: before launch, a native speaker tests common conversations in each language.
- Local details: currency, date formats, phone formats and local terms.
Handover to your team
Your team may not speak every language. The assistant should:
- Summarise each conversation in your team's language on the CRM record.
- Record the customer's language, so replies and follow-ups use it.
- Hand over to a speaker of that language where you have one, or explain clearly that a person will reply, and when.
