One Catalog, Several Countries: AI Answers Must Follow the Market

A customer in Lyon asks whether a jacket is in stock and what it costs. The answer has to be true in France, in euros, in French, for the version of the jacket sold there. An answer that is correct for Germany is still a wrong answer.

Most catalogs serve several countries. Translation is the visible part of that work. The harder part is that the facts themselves change from one market to the next. An AI advisor that reads the whole catalog as one body of knowledge will mix them.

What changes from one country to the next

Price and currency. The same product rarely has a single price. Taxes, currency and promotions differ by country. In the EU, the Consumer Rights Directive requires the total price, taxes included, to be given before a distance contract. Since May 2022, the Price Indication Directive also requires an announced price reduction to state the prior price, the lowest price applied in at least the 30 days before the reduction. A discount computed from one market's price history does not hold in another. In Switzerland, the Price Disclosure Ordinance requires online offers aimed at Swiss customers to show the price actually payable in Swiss francs, VAT included.

Stock and delivery. A product can be available for one country and sold out for another, or not delivered there at all. Delivery times and costs follow the destination.

Language and vocabulary. Switzerland alone has four national languages: German, French, Italian and Romansh. Customers also use their own local words for the same product. In France, the law of 4 August 1994 requires French in the designation, offer and description of goods sold to consumers, online included.

Variants and formulas. A product sold under the same name can come in a different size, range or formula from one country to another. Since the Omnibus Directive, marketing a product as identical in several EU countries when its composition differs significantly can be a misleading practice, unless legitimate and objective factors justify the difference.

Claims and mandatory information. What a merchant may say about a product, and what it must say, follows the rules of each market. Switzerland is not part of the EU and applies its own consumer rules.

These rules serve as examples and are not legal advice. Each market calls for its own review.

What goes wrong when markets mix

An AI advisor that does not know which market the customer is in can make four kinds of mistakes.

• It quotes a price from another country, sometimes in the wrong currency.
• It confirms a product that is not sold or delivered there.
• It describes the size or formula of another version.
• It repeats a claim the merchant approved for one market only.

Each of these is a wrong answer given with confidence. The customer does not see a translation problem. They see a store that does not know its own products.

The same risk exists outside the store. An LLM answering a customer in Spain can quote a price it found on a German page. Clear product information also helps there, as explained in GEO for e-commerce.

What you need to prepare before opening a market to AI

• List, for each product, the markets where it is sold and delivered.
• Keep price, currency, taxes and promotions per market, with the prior price whenever a reduction is announced.
• Record the variants, sizes and formulas that differ by country.
• Approve claims and mandatory information market by market, in the language of that market.
• Decide how fresh price and stock must be, and what the advisor says when it cannot confirm them.
• Test the advisor from each country, in each language, with the questions customers actually ask.

How Querytail approaches it

Brand Agent runs in production in Switzerland, in French, German and English. Answering in three languages is the visible part. Keeping every answer inside one market is the part customers only notice when it fails.

In Querytail, the market belongs to the fact. Each price, availability, variant or claim carries the markets where it applies, and the merchant approves it for those markets in Merchant Console. Each customer is routed to the knowledge approved for their country, with price and stock kept up to date. A merchant opens a new market with knowledge approved for it, not copied from another one.

FAQ

Is translating the catalog enough? No. Translation changes the words. The price, availability, variant and legal wording can change too.

Can one AI advisor serve several countries? Yes, if each answer stays within the knowledge approved for the customer's market, and the advisor says so when a fact cannot be confirmed for that market.

Does this matter for LLMs as well? Yes. ChatGPT, Gemini or Perplexity can mix markets when they describe a product. Clear product information on each country site reduces that risk, but nobody controls how a third-party model answers.
