How to translate your catalog with AI to sell in other countries

TLDR: Translating a catalog stopped being a budget line and became a process, but the failure is still the same: translating without adapting. An assistant covers the bulk of the text for $8 a month, Jasper holds tone across large catalogs, and HeyGen dubs video keeping your voice. The non-negotiable condition is a native review before opening the market.

This guide is for stores already working in their home country seeing traffic or orders from abroad. The temptation is translating the whole catalog into five languages at once, and that is exactly the mistake that turns an opportunity into a customer service load in languages nobody on the team speaks.

The rule that orders the decision: every published language is a service commitment, not a configuration checkbox.

1. Pick one market and commit to it

Before translating a line, pick a country. The criteria that matter are practical: where your existing traffic comes from, where you can ship at reasonable cost and speed, where tariffs do not kill you, and which language you can serve when questions arrive.

That last point rules out most expansion fantasies. If nobody on your team can answer an email in German within twenty-four hours, publishing in German generates angry customers, not sales.

Also note what changes legally: mandatory information, withdrawal rights, warranties and tax details vary by country and are not translated, they are replaced. That part is worth checking with an adviser in the destination market before opening.

2. Translate the catalog by priority, not entirely

Translating two hundred pages at once wastes work, because 80% of your sales come from a handful of products. Start with the twenty best sellers and the pages that decide the purchase: shipping, returns, warranty, about us and the FAQ.

For translation work, YesChat lets you compare how GPT and Claude handle the same text, and in translation that comparison is useful because models differ noticeably in naturalness. Free plan to test the method, paid from $8 a month.

If the catalog is large and several people work on it, Jasper keeps the brand voice profile applied in the new language too, from $59 a month with a seven-day trial. That is the difference between a translated catalog and a catalog that sounds like your brand in another language.

3. Adapt what does not travel

Here is the real work, and where an international store separates from a translated one. Four categories of things get replaced, not translated.

Units and measurements: clothing and shoe sizes, metric or imperial, voltages and plugs. A customer who buys the wrong size because of a botched conversion returns the product and does not come back.

Commercial formats and expectations: usual payment methods, delivery times considered normal, whether free shipping is a standard in that market or a luxury.

Expressions: wordplay, idioms and slogans are not translated, they are rewritten with their equivalent. A literally translated tagline sounds foreign even with perfect grammar.

And images with burned-in text, which have to be regenerated in the new language or they stand as the visible reminder that the site is a translation.

4. Dub the video and review with a native speaker

If you have product video or ads, HeyGen translates them keeping your cloned voice and adjusting lip movement, with a free plan of three videos a month and paid from $24 annually. The full method is in the AI video dubbing guide.

And now the part that does not get skipped: before opening the market, someone who speaks the language natively reviews the priority catalog, the legal and commercial pages and the video pieces. Not a skim, a review with the products in front of them. It is an afternoon of a professional’s work and it separates a credible store from one people close in five seconds.

With the market open, customer service in the new language rests on the translated documentation, following the AI customer service guide. The whole sector lives in AI for e-commerce.

Common mistakes

Opening five languages at once. It multiplies service and maintenance load fivefold before you know whether any of them works. One, done properly, then the next.

Translating without adapting sizes and units. It is the leading cause of returns in international selling and the easiest to avoid.

Leaving legal pages in the original language. Beyond the trust problem, mandatory consumer information changes by country and translating it is not enough.

Publishing without native review. Machine translation gets the grammar right and misses the nuance, and nuance is exactly what decides whether a customer trusts a foreign store.

Frequently asked questions

How much does translating a catalog with AI cost?

The bulk of the text is handled from $8 a month with an aggregator, or from $59 with Jasper if you need brand voice across a team. The real cost to budget is the native review, which remains human work.

Can I skip the native review if the text reads well?

Reading well is exactly what deceives. The errors that matter are not grammatical, they are register, local expression and commercial expectation, and only someone from the market catches those.

Which market should I open first?

The one already sending you traffic and where you can ship at reasonable cost and speed. Existing demand is a better indicator than market size.

Should I translate customer reviews too?

Better to show them in their original language with optional translation. Machine-translated reviews lose credibility, and in many markets platforms have specific rules about how they can be presented.
