Multilingual customer service: serving Slovak, Romanian and Austrian customers
Short answer
Foreign shoppers ask the same questions as domestic ones: delivery, returns, payment, product. The assistant answers in the customer’s language, even if the knowledge base is in another language. The legal texts and delivery terms, however, need to be localised.
Technically, it is easy today for an online store to sell to neighbouring countries. From Hungary, for example, couriers deliver to Bratislava, Cluj-Napoca and Vienna, and payment can also be handled in euros or lei. Many, however, are held back by customer service.
Foreign shoppers ask the same questions as domestic ones; they just arrive in a different language. Below is what the assistant takes on, what needs to be localised, and which rules apply to cross-border customer service.

What foreign shoppers ask
The topics are the same; at most the proportions change. Delivery: how long, how much, can it be tracked. Returns and withdrawal: how, who pays, when the money comes back. Payment and currency: in euros or lei, is cash on delivery available. Product: size, compatibility, stock. Order status: where the parcel is.
The answers are already in the online store and in the internal rules, only in one language. The essence of multilingual customer service is to pass on this existing knowledge in the customer’s language.
So most of the preparation is the same: put the content in order, and formulate the answer in the customer’s language.
How it answers from a knowledge base in another language
The assistant works from the product data and the uploaded documents. When a Slovak shopper asks a question in Slovak, it recognises the language, looks for the answer in the knowledge base, whatever its language, and answers in Slovak. Where one exists, it can also refer to the relevant page.
This means you do not need to maintain a separate knowledge base for each language. If the delivery fee changes, you change it in one place, and the assistant gives the new fee in every language.
For a foreign language, it is worth uploading the localised legal text. That way the assistant refers to it on legal questions, in place of a machine translation.
What must be localised in any case
The assistant handles the conversation, but there are a few things you need to put in order before you sell abroad.
The general terms and conditions and the withdrawal information, in the given language. If the online store specifically targets customers in another country, the consumer protection rules of that country may also apply. It is worth having the legal texts prepared by a professional in the given language; machine translation is not enough.
The delivery terms by country: fees, deadlines, courier service. Prices and currency, clearly, and the same at the moment of payment. The returns address and process: where, how, who pays.
Rules to watch out for
These points affect almost every cross-border online store. This guide is for information only and does not replace advice from an accountant or a lawyer.
VAT and the one-stop shop. Under Directives 2017/2455 and 2019/1995, if EU distance sales reach the threshold of 10,000 euros a year, the VAT of the customer’s country must be charged. The OSS simplifies the administration: you do not need to register separately in every country.
The 14-day right of withdrawal. For online purchases, consumers are entitled to it throughout the EU, under Directive 2011/83/EU. The customer must be informed about it clearly, in their own language.
The Geo-blocking Regulation. Under Regulation (EU) 2018/302, you may not restrict the access of a customer from another Member State without justification, and you may not redirect them to another country version without their consent. You are not, however, obliged to deliver everywhere.
The question of applicable law. If you specifically direct your activity at consumers in another country, under Article 6 of the Rome I Regulation the consumer is entitled to the mandatory consumer protection rules of their own country.
When it hands over to a human
The assistant has to know what it does not know. It is worth setting clear handoff rules: complaints, damaged or incomplete parcels, grievances, irritated customers, requests for individual quotes, and every question for which there is no content.
On handoff, your colleague sees the conversation so far, so they do not need to ask again what the customer has already said. It is worth deciding in advance who handles handoffs in foreign languages.
Marking the handoff also matters. The assistant indicates that artificial intelligence answered, and the switch to a human is also marked, in line with Article 50 of the EU AI Act.
What to measure
Measure the first response time by language, especially in the evening and at the weekend. In our own platform data, 51.8 percent of visitor questions arrive outside business hours (customers in Hungary, CET).
Also measure the handoff rate: if it is exceptionally high in one language, something is probably missing from the knowledge base there. Also watch the recurring questions by language: it is worth putting the common answer on the product page.
It is also worth measuring cart abandonment after a question. If people still do not buy after the answer, the terms may be the problem.
Next step
Language is no obstacle to serving customers, but you need to localise the legal layer. Request a demo on your own website, or see the prices. If you have a question, write to .

Frequently asked questions
Multilingual online store support with an AI assistant
Is a knowledge base in one language enough?
For everyday questions, yes: the assistant answers from the existing content in the customer’s language. It is worth uploading the legal texts in the given language.
In what language does the assistant answer?
It answers in the customer’s language, even if the knowledge base is in another language. It formulates the answer from the original content, but gives it in the customer’s language.
What must be localised in any case?
The general terms and conditions, the withdrawal information and the delivery terms by country. These must be legally accurate in the given language.
Do I need separate VAT registration to sell abroad?
If EU distance sales reach the threshold of 10,000 euros a year, the VAT of the customer’s country is due. The one-stop shop (OSS) lets you handle this in one place. Your accountant decides what needs to be done.
Can I block foreign customers?
You may not restrict their access without justification. You do, however, decide where you deliver, and the customer can collect the goods at the specified location.
When does the assistant hand over to a human?
For complaints, damaged parcels, grievances and every question for which there is no content. In these cases it asks for contact details and hands over to a colleague.
