Most UK and US companies enter Central Europe with two assumptions, both wrong. The first is that it is a discount market: same product, lower price, cheaper labour. The second is that the sales motion transfers if you translate the deck. I have watched both assumptions cost a full year of runway.
What follows is not a cultural-differences listicle. It is the specific mechanics that change how a deal progresses, drawn from selling and building teams across Czechia, Poland, the DACH region and the Nordics.
Committee shape
The single biggest forecast error is assuming your champion has the authority their title implies.
In the UK, enthusiasm is cheap and often means nothing. In much of CEE, it is expensive and usually means something. Calibrate accordingly.
Contracting and procurement
Three things reliably add weeks that Anglo teams do not budget for. Local-entity preference: many mid-market and public-adjacent buyers strongly prefer, and occasionally require, a counterparty with an EU entity and a VAT number they recognise. Currency and invoicing: quoting in GBP into a CZK or PLN business pushes FX risk onto the buyer and it will come back as a discount request at signature. And data residency: in DACH especially, "where is it hosted" is a first-meeting question, not a legal-review question.
None of these are dealbreakers. All of them are cheap to solve in advance and expensive to discover in week nine of a deal you have already forecast.
Why translation is not localisation
Business English is functional across all four regions, and most of your buyers speak it well. The problem is not vocabulary. It is that Anglo B2B messaging is built on claims (transform, unlock, 10x) and those claims read as unserious in markets where credibility is established by specificity.
Where language does matter is the first touch and the contract. Outbound in the local language lifts reply rates materially in Poland and Czechia; a contract offered in local language alongside English removes a legal objection before it forms. Everything in between can be English.
A sequencing that works
The companies that struggle in CEE are almost never the ones with the wrong product. They are the ones who ran a UK playbook faster and louder and concluded the market was slow.
