The Czech Trust Stack: 12 Signals Your Website Needs

By RKP Agency, Prague10 min read
The short answer
  • Czech shoppers verify before they buy. Reviews, a checkable company identity and transparent checkout terms are the conditions of the sale.
  • An APEK survey found 97% of Czech customers use reviews when choosing an e-shop (reported by Heureka). A foreign brand with no review footprint starts behind.
  • The trust stack has four layers: legal identity, social proof, transparent checkout, and Czech-language contact. A gap in any one reads as risk.
  • This is a checklist you can hand to your web team. Twelve signals, grouped and prioritised.

Why trust is the Czech conversion problem

A foreign brand entering Czechia starts with a trust deficit it did not have at home: no local reputation, no Czech reviews, an unfamiliar name. Czech shoppers are practised at spotting that gap. They compare sellers, read reviews and check who they are buying from before handing over money. Get the product and price right but leave the trust signals missing, and you will pay for traffic that hesitates and leaves.

The good news: trust signals are concrete and fixable. Below is the “trust stack” — the twelve things a Czech-facing site needs, grouped into four layers.

97%
of Czech customers use reviews when choosing an e-shop (APEK, via Heureka)
76%
prefer to buy in their own language; 40% never buy otherwise (CSA Research, 2020)
77% / 69%
abandon over missing delivery / returns options (DHL, 2026)
An APEK survey found that 97% of Czech customers take reviews into account when choosing an e-shop; Heureka reports that for 44% of users reviews are a stronger argument than the lowest price.

Layer 1: Legal identity — prove you exist

The first question a cautious Czech buyer asks about an unknown seller is simply: are these people real, and can I find them if something goes wrong? Make the answer obvious.

  1. IČO and registered address

    Show your Czech company ID (IČO) and registered address in the footer and on the contact page. It lets anyone verify the entity in the state ARES register — the Ministry of Finance’s business lookup. Traceability is the baseline of trust.

  2. Legal form and VAT details

    State the legal form (e.g. s.r.o.) and VAT number (DIČ) where relevant. It signals a real, accountable business rather than an anonymous storefront.

  3. Terms, returns and complaints (reklamace) in Czech

    Publish clear terms, a returns policy and a process for handling product complaints (reklamace) in Czech. Czech consumer rights are well understood by shoppers; vagueness here reads as evasion.

Layer 2: Social proof — let other Czechs vouch for you

This is the layer foreign brands most often skip, and the one Czech shoppers most rely on. With 97% of customers using reviews to choose an e-shop, a blank reputation starts you at a competitive disadvantage.

Verified customer reviews and a trust seal as Czech social proof
  1. A Heureka presence with reviews

    List on Heureka and actively gather reviews. It is where Czechs compare and judge sellers, and being absent while competitors are present with strong ratings is conspicuous.

  2. The “Ověřeno zákazníky” badge

    Heureka’s Verified by Customers certificate is earned through post-purchase feedback (the blue tier needs a strong recent review volume with 90%+ recommending; gold needs 97%+). It is a recognised Czech trust mark — Heureka claims half of customers shop only at certified e-shops. Check the current programme terms, revised from September 2025.

  3. Authentic, specific reviews on your own site

    Show real customer reviews with names and detail rather than anonymous marketing testimonials. Genuine, specific and occasionally imperfect reviews convert; too-perfect ones raise suspicion.

Layer 3: Transparent checkout — no surprises

Trust survives right up to the final screen, where hidden costs and missing options quietly kill it. In DHL’s 2026 survey, 77% of Czech shoppers would abandon over a missing preferred delivery method and 69% over missing returns options.

  1. Prices in CZK, VAT included, delivery shown early

    Display final prices in Czech crowns with VAT, and show delivery cost before the last step. A cost that appears only at checkout is the classic trust-breaker.

  2. Cash on delivery (dobírka)

    Offer dobírka. For a first purchase from an unfamiliar seller it is the safety net that converts cautious buyers who will not prepay an unknown foreign brand.

  3. Pickup points and lockers (Zásilkovna)

    Offer collection points and parcel lockers alongside home delivery. They are a mainstream Czech default, and their absence removes the option many buyers prefer.

  4. Delivery time in working days, accounting for Czech public holidays

    State a concrete delivery time in Czech working days. “Ships from abroad, timing unclear” is an unanswered risk the buyer resolves by leaving.

Layer 4: Czech contact — be reachable, in Czech

The final layer answers “if I need help, can I get it, in my language?” With 76% of consumers preferring to buy in their own language and 40% refusing otherwise (CSA Research, 2020), this is not decoration.

  1. Czech-language site and support

    Provide the site and customer service in native, localized Czech rather than machine translation. Support in Czech signals commitment to the market and removes the friction of communicating in a second language.

  2. A Czech phone number (+420) and clear contact details

    Show a reachable +420 phone number and a real contact point. A local number tells the buyer there is someone here to answer — the human end of the traceability that IČO and address begin.

Frequently asked questions

What is the single most important Czech trust signal?

Reviews. An APEK survey (reported by Heureka) found 97% of Czech customers use reviews when choosing an e-shop, and for 44% they outweigh the lowest price. A Heureka presence with genuine reviews and the Verified by Customers badge is the highest-leverage place to start.

Why do I need to show IČO and a Czech address?

They let a cautious buyer verify your company exists in the state ARES register and know who is accountable if something goes wrong. Traceability is the baseline of trust; an anonymous foreign storefront gives buyers a reason to hesitate.

Is the “Ověřeno zákazníky” badge worth it?

For most consumer categories, yes. It is a recognised Czech trust mark earned through real post-purchase feedback rather than self-selected testimonials. Heureka claims half of customers shop only at certified e-shops. Confirm current terms, which changed from September 2025.

Do I need a Czech phone number if I offer email support?

It helps significantly. A +420 number signals there is a reachable person in-market, which reduces the perceived risk of buying from a foreign brand. Combined with Czech-language support, it turns “who are these people?” into “I can reach them if needed.”

We’re B2B — do these still apply?

Most do. Legal identity, Czech-language contact and clear terms matter in B2B too; reviews and dobírka matter less than references, case studies and a named contact. The layers are the same; the specific signals shift toward credibility and accountability.
