How one team serves customers in 19 languages

When doing cross-border business, the first bottleneck is often not logistics but language. A German customer sends a question about returns in German, a Japanese customer asks about sizing, and no one on the team can understand it. All they can do is copy it into translation software and paste back and forth—replies are slow, mistakes are easy to make, and customers can feel it.

Hiring a customer service agent who speaks the local language for each market is of course ideal, but for most small and medium-sized online stores it is not realistic. Below is an approach for covering multilingual markets with a small team.

Step 1: Let AI answer in the customer's language first

Most customer questions are repetitive: how long shipping takes, how much shipping costs, how to return or exchange, whether a particular item is in stock. These are the best questions to hand to AI.

The key is that AI must answer directly in the customer's language, rather than giving the customer a piece of English that sounds heavily machine-translated. Yinke's approach is:

• The chat widget displays the relevant language based on the visitor's location, including interface text and the welcome message.
• AI follows the language the customer uses; if the customer says “Please answer in English,” it will keep using English from then on.
• Customers can also switch languages themselves in the widget.

Step 2: Write the knowledge base in only one language

Many people assume multilingual customer service requires multiple sets of materials. It doesn't: one knowledge base written in the language you know best is enough. AI will understand what the materials mean and then compose an answer in the customer's language.

What really takes effort is writing the materials clearly: spell out the conditions, numbers, and exceptions. A clearly written return policy in Chinese is far more useful than three vague multilingual versions.

Step 3: Human agents take over with the help of real-time translation

Issues AI cannot handle—such as damaged products or refunds that require negotiation—still need to be handed to a person. At that point, language becomes a barrier again.

The solution is two-way real-time translation in the customer service workspace: the customer's foreign-language messages are automatically translated into the agent's language, the agent replies in their own language, and the message is translated into the customer's language when sent. The customer always sees their own language, and the agent does not have to leave the workspace.

Combined with AI reply suggestions and conversation summaries, an agent who only speaks Chinese can smoothly handle an after-sales issue for a Spanish customer.

Step 4: Keep filling the gaps with data

After launch, regularly review the questions AI cannot answer. These usually fall into a few categories: new product information, customs duties for a particular country, and holiday shipping schedules. Add the answers to the knowledge base, and the next customer who asks the same question in any language will get an answer.

Summary

Multilingual customer service does not necessarily mean a multilingual team. Let AI handle common questions in the customer's language, let human agents handle difficult issues with the help of translation, and maintain only one knowledge base. That way, a small team can serve multiple language markets at the same time.
