Expanding your online store to Hungary, Czechia and Poland: what to prepare before the first euro on ads

The region is a convenient fiction

For a brand in Romania, the next markets are obvious: Hungary, Czechia, Poland. Similar size, EU rules, a day's drive for a parcel. The mistake is treating them as one launch. Payment preferences, delivery expectations, price sensitivity and search behaviour differ enough that a campaign copied from Bucharest to Budapest usually fails for reasons that have nothing to do with the ads.

What follows is the order in which I prepare a multi-market launch, based on running accounts across all four countries.

1. Payment and delivery before anything else

Cash on delivery still matters in Romania and Hungary, less so in Czechia, and Poland has its own dominant methods that a Romanian checkout will not have by default. If the preferred local method is missing at checkout, no amount of traffic converts.

Delivery expectations are similar: locker networks are the default in Poland, and a shop that only offers courier to door looks foreign. Show the local delivery options and realistic timing on the product page, not only at checkout.

2. VAT, pricing and the OSS regime

Once your consumer sales across the EU pass the distance-selling threshold, you charge the VAT rate of the customer's country and report through the One Stop Shop. Rates differ by several points between these four markets, which changes your margin per country even at the same shelf price. Decide early whether you price to a fixed margin or to a local competitive price, and let finance model both before launch.

3. Language is a conversion factor, not a translation task

Machine-translated or literally translated product pages are recognised instantly by native speakers and read as untrustworthy. In these markets, trust is the main barrier for an unfamiliar foreign shop. Have product pages, checkout, emails and customer service scripts written by a native marketer, not just checked by a translator. Search terms differ too: the keyword a Hungarian buyer types is rarely a direct translation of the Romanian one.

4. Tracking per market, from day one

Set up GA4, consent mode and conversion tracking so you can read results by country from the first order. That means consistent currency handling, correct hreflang, separate conversion actions or clear market dimensions, and a test order in each market through the full chain. Without this, you will be comparing campaigns across countries with data that is not comparable.

See the earlier article on missing conversions for the checklist; every point applies per market.

5. Research each market, even lightly

Eight interviews per country is enough to learn that the buying trigger differs. On a supplements brand, the Hungarian market responded to a different angle than the Romanian one, and the campaign built on that angle reached a 6.8x ROAS with a 20% lower cost per acquisition than the original Romanian creative adapted directly. The difference was not media buying. It was knowing what to say.

6. Launch one market, then the next

Launch the market where your checkout, language and tracking are cleanest. Run six to eight weeks, fix what breaks, document it, then open the next one with the fixes already applied. Launching three markets at once triples the problems and divides the attention.

Platform choice matters here. A multi-market setup on Shopify or a comparable platform with market-level pricing, currency and domains makes the sequence manageable. Separate shops per country do not.

What this looks like as a plan

Checkout and delivery audit per market, VAT model, native copy, tracking per market, light research, then a sequenced launch with a budget that grows as each market proves out. It fits on two pages and takes four to six weeks to prepare properly. It is also the core of the operational marketing plan I build for brands moving into the region.
