CTIA vs. Corporate E-shop

What audits address and what sanctions may be imposed

An inspection by the Czech Trade Inspection Authority (ČOI) of a corporate e-shop examines the entire purchasing process, from pre-order information, discounts, and reviews, to complaints and withdrawals from the contract. Errors often occur unintentionally, but they can lead to a fine, and an inspection can be triggered by a customer complaint or a mystery shopping purchase. In this article, you will find out what to adjust on your website and in your terms and conditions, how to prepare for an inspection, and which practices to avoid.

CTIA vs. Corporate E-shop

Key takeaways

Inspections by the Czech Trade Inspection Authority (ČOI) reveal non-compliance in the vast majority of e-shops. In the first quarter of 2024, the authority identified legal violations in 78.48% of the entities inspected, with error rates exceeding 87% in other monitored periods.
Legislation is too complex for companies to implement flawlessly. The Consumer Protection Act evolves so rapidly that most violations arise not from intent, but from mere oversight or an inability to keep pace with current amendments.
ČOI inspectors employ mystery shopping to verify the entire transaction process. They do not merely wait for consumer complaints; they actively monitor your e-shop from the moment an order is placed, through the delivery of goods, to the potential withdrawal from the purchase agreement.
The three most frequent infringements form the core of the ČOI inspection checklist. In the first quarter of 2024, the authority recorded 92 cases of inadequate information regarding claims, 71 cases of unfair commercial practices, and 45 cases of non-compliance concerning information on withdrawal from contracts.

Why is a ČOI inspection a real risk? Alarming figures from practice

According to press releases from the Czech Trade Inspection Authority (ČOI), in the first quarter of 2024, for example, violations of legal regulations were detected in 78.48% of the inspected e-shops. In other monitored periods, the error rate even exceeded 87%. These numbers do not mean that eight out of ten business owners are fraudsters.

Above all, this statistic shows that consumer legislation, especially the Consumer Protection Act, is so complex and rapidly changing that many companies fail to implement all changes correctly in time. Errors are thus often the result of omission, not direct intent.

Inspections can be initiated based on a complaint from a dissatisfied consumer, but the ČOI also conducts its own extensive monitoring. It commonly uses the "control purchase" method to verify the entire process from order to delivery and potential withdrawal from the contract.

Our Czech legal team at ARROWS has extensive experience with the methodology of ČOI inspections. We know how inspectors proceed, what details they focus on, and what their decision-making practice is. For an immediate assessment of your situation and preparation for an inspection, write to us at consultation@arws.cz.

What does an e-shop have to comply with? From terms and conditions to the order button

ČOI inspectors know exactly what to look for. They focus on a clear checklist of obligations that every e-shop must meet under Czech legislation.

ČOI statistics for the first quarter of 2024 clearly defined the three most common offenses:

1. Insufficient information about the complaints process (92 cases).

2. Use of unfair commercial practices (71 cases).

3. Insufficient information on the conditions of withdrawal from the contract (45 cases).

Let's look at the details where companies make mistakes most often.

Information obligation: Complaints, withdrawal, and ADR

An e-shop must actively and clearly inform consumers about the scope, conditions, and method of filing a complaint. The same applies to the statutory 14-day period for withdrawal from a contract when purchasing remotely. A very common and easily detectable error is the failure to provide a model withdrawal form.

Another massive offense is the lack of information on alternative dispute resolution (ADR). E-shops have a legal obligation to state information on their website and in their terms and conditions about the ADR entity, which for most e-shops is the Czech Trade Inspection Authority (ČOI).

FAQ – Legal tips for terms and conditions

1. Do I really have to provide information about ADR (ČOI)?

Yes, it is a direct obligation under Section 14 of the Consumer Protection Act. Missing information is one of the most frequently and easily fined offenses. If you are dealing with a dispute with a customer, our Prague-based legal team is ready to help you – write to consultation@arws.cz.

2. Can a customer return goods without the original packaging?

Yes, they can. Conditioning the withdrawal from the contract on returning the goods in their original, undamaged packaging is illegal. However, you may be entitled to compensation for the diminished value of the goods if the customer handled them beyond what was necessary to familiarise themselves with the goods.

3. What if I sell goods that cannot be returned (e.g., custom-made)?

The law defines clear exceptions to the right of withdrawal (e.g., perishable goods, goods in sealed packaging for hygiene reasons, or custom-made goods). However, you must inform the consumer about this clearly and in advance. Need legal assistance with setting up your terms? Contact us at consultation@arws.cz.

Technical requirements: Watch out for the order button

Due to European legislation, the order button must be formulated in such a way that it is completely clear to the consumer that by submitting the order, they commit to payment.

The recommended, though not the only permissible, formulation is "Order with obligation to pay". Simple texts such as "Order" or "Buy" are highly risky, and the ČOI actively fines them as a violation of the law.

These formal requirements are the basics that every corporation and smaller company must have in order. The Prague-based legal team at ARROWS will prepare complete terms and conditions for you, containing all legal requirements, including correct information about ADR and the withdrawal process. Get in touch with us at consultation@arws.cz to get a tailored legal solution.

Unfair commercial practices: When discounts and reviews become a nightmare

Now we come to the area where the ČOI imposes the highest fines. This is where the line between administrative omission and intentional deception of the customer lies.

Unfair commercial practices is a broad term that includes both misleading actions (Section 5 of the Consumer Protection Act) and misleading omissions (Section 5a). It refers to any conduct that may induce a consumer to make a transactional decision they would not have otherwise made.

New ČOI focus 1: Fake discounts (Omnibus Directive)

The new rules introduced by the European Omnibus Directive have fundamentally changed the rules of the game for marketing campaigns. When announcing a discount (e.g., "Now -20%"), you must state the lowest price at which you offered the product in the last 30 days as the reference price.

The era of calculating discounts from "original prices", "recommended retail prices", or prices just before the discount has ended. This is not only a legal but also a technical issue for e-shop settings. Incorrectly displaying discounts carries a fine of up to CZK 5,000,000; if it is also a misleading practice addressed in a cross-border action by EU supervisory authorities, the fine can be up to 4% of annual turnover.

New ČOI focus 2: Fake reviews

The era of fake reviews is ending. It is now explicitly forbidden to publish fake or distorted reviews. E-shops are now obliged to state whether and how they ensure that reviews come from real consumers who actually purchased the product.

Case study: The case of LUNZO s.r.o. (Fine of CZK 750,000)

This is not just theory. LUNZO s.r.o. was fined CZK 750,000 in a final decision. The reason was that it engaged in an unfair commercial practice by actively deleting negative reviews and modifying ratings.

As part of a control purchase, a ČOI inspector gave a product a 1-star rating with a negative comment. The e-shop subsequently modified this review to 5 stars. The intent to deceive the consumer was thus clearly proven.

Your e-shop's marketing must know its legal limits. The Prague-based legal team at ARROWS will provide professional training for your employees (including a certificate) so that your marketers and managers know exactly how to work with discounts and reviews in compliance with the Omnibus Directive. Write to us at consultation@arws.cz.

Aggressive practices and obstruction: When an inspection turns into a disaster

There are offenses that the ČOI punishes exemplarily because they go directly against the basic principles of fair trade. These include aggressive commercial practices, such as sending unsolicited goods and subsequently demanding payment.

Case study: The case of Mincovní obchod (Fine of CZK 400,000)

The e-shop Mincovni-obchod.cz received a fine of CZK 400,000. The reason was the repeated sending of unsolicited shipments as part of a so-called "collector's service" that consumers had not ordered.

Case study: The case of Deal Extreme Czech (Fine of CZK 100,000)

This case is a warning for every IT manager or director. The company received a fine of CZK 100,000, which consisted of two parts. One was for unfair practices, but the second (amounting to CZK 50,000) was imposed because the operator actively blocked ČOI inspectors' access to the website (likely based on IP addresses) and failed to cooperate during the inspection.

Obstructing an inspection is a procedural foul that only convinces the authority that you have something to hide, and it leads to a separate, easily provable fine.

If the ČOI contacts you, it is crucial to respond professionally and factually. Our lawyers will provide complete representation before administrative authorities. We will take over communication with the inspectors and ensure that the inspection and any administrative proceedings are conducted correctly. For an immediate solution to your situation, write to us at consultation@arws.cz.

Selling in the EU? International reach of inspections and ARROWS International

The issue of compliance with consumer law does not end at the Czech border. If you, as a Czech e-shop, sell goods to consumers in other EU countries, you must also face cross-border complaints. These complaints are primarily handled by the network of European Consumer Centres (ECC). Crucially, the European Consumer Centre Czech Republic operates directly within the Czech Trade Inspection Authority.

Thus, if a German consumer complains about your e-shop to the German ECC, this complaint is forwarded to the Czech ECC, which is based at the ČOI. The path to initiating an inspection of your e-shop is therefore very short and institutionalized.

FAQ – Legal tips for selling in the EU

1. Do Czech rules apply when I sell to a German customer?

Simply put, you must comply with at least the standard of protection provided by the law of the consumer's country (the Rome I Regulation). In addition, you expose yourself to the supervision of local authorities and mechanisms, such as the ECC. We handle international cases daily, write to us at consultation@arws.cz.

2. What is the ECC network and why should I care?

It is a network of centres for the alternative resolution of cross-border consumer disputes. If you have a problem with a customer from another EU country, the dispute will highly likely go through the ECC, which is organizationally linked directly to the ČOI in the Czech Republic.

FAQ – Most frequent legal questions about ČOI inspections

1. What is the maximum fine from the ČOI for an e-shop?

The sanctions are high. For unfair commercial practices, such as manipulating discounts (Omnibus) or reviews, the fine can reach up to CZK 5,000,000, and in coordinated cross-border actions by EU supervisory authorities, up to 4% of the seller's annual turnover. For missing information about the ADR entity on the website and in the terms and conditions, a fine of up to CZK 1,000,000 may be imposed, and for missing information on alternative dispute resolution in pre-contractual information, up to CZK 5,000,000. If you are facing administrative proceedings, contact us immediately at consultation@arws.cz.

2. What is an "unfair commercial practice"?

It is any action (or even omission of information) that may lead a consumer to make a transactional decision they would not have otherwise made. This includes false information, hidden fees, fake reviews, or aggressive practices.

3. Do I really have to verify whether a review was written by a customer?

Yes. If you publish reviews, you must transparently inform whether and how you verify that they come from real consumers. If you do not verify, you must admit it. Publishing unverified reviews as verified is an unfair practice. We will help you set up this process, contact us at consultation@arws.cz.

4. Can the ČOI conduct a control purchase anonymously?

Yes. A control purchase is a completely standard tool. The inspector acts as a regular consumer to verify the entire process, including communication, delivery, and potential withdrawal from the contract. To prepare for an inspection, contact us at consultation@arws.cz.

5. What should I do when I receive an inspection report?

Stay calm and do not sign or agree to anything without consulting a lawyer. The report is the basis for any administrative proceedings. You have the right to comment on it and propose evidence. Contact us immediately at consultation@arws.cz, we will secure your representation.

6. I have heard about a list of "risky e-shops". What is it?

The ČOI maintains and regularly updates a public list of websites warning consumers. The reason is typically the anonymity of the operator, untraceable terms and conditions, or a large number of complaints. Finding yourself on this list is devastating for a business's reputation. If you are dealing with a dispute with the ČOI, we are ready to help you at consultation@arws.cz.
