Safelisting
Safelisting: Early warning
system for price
discrepancies and listing
errors in online retail
One wrong click, one transposed number – and suddenly a retailer is faced with a costly problem. In online retail, a single pricing error can be enough to trigger costly warnings, official fines or even a court-enforced delivery obligation. Safelisting from PREISmonitoring acts as a proactive early warning system here: by automatically monitoring and documenting product listings on marketplaces, it protects retailers from small errors turning into major damage. Even minor deviations in prices or warnings can result in legal action, while new regulations are further tightening requirements. Anyone who wants to be successful in e-commerce in the long term therefore needs full control over the presentation of their offers – and this is exactly where Safelisting comes in.

A ruling by the Frankfurt Higher Regional Court in April 2024 with drastic consequences illustrates how quickly an incorrect price tag can lead to a binding purchase contract. In the case in question, a retailer offered high-quality smartphones for £92 instead of the regular price of £1,099. Despite the obvious error, the court ruled that the retailer had to deliver nine of these devices at the drastically reduced price (Frankfurt Higher Regional Court, 18 April 2024, ref. 9 U 11/23). The decisive point in the reasoning for the judgement was not the pricing error itself, but the retailer's behaviour after the order was placed. By sending extras that were part of the offer, the retailer had, in the court's opinion, implicitly confirmed the purchase contract. A subsequent challenge on the grounds of error was therefore no longer successful.
This case is a lesson in the financial risks that can arise from undetected pricing errors. It shows that it is not only the incorrect entry that is decisive, but the entire process chain after the purchase. If an automated early warning system had immediately reported the pricing error, the retailer would have been able to recognise the error immediately and cancel incoming orders – before legally binding actions such as the shipment of goods or accessories took place. The seamless monitoring of one's own prices is therefore an essential protective mechanism against incalculable financial losses.
Marketplace liability trap:
Who is responsible for
automatic content?
Online marketplaces such as Amazon are dynamic ecosystems in which product presentations are often automatically adjusted. Examples include machine translations for international customers, format changes to standardise the appearance, or the addition of content from other sources. What is intended to increase reach also creates a considerable legal grey area and a liability risk for sellers.
A ruling by the Hamburg Regional Court on 11 May 2023 (Ref. 327 O 188/22) has provided clarity on this issue – but to the detriment of retailers. The court ruled that sellers are also liable for automatically generated content on marketplaces, eve ly if they did not create or initiate it themselves. Accordingly, the responsibility for the legality of the entire product listing, including all changes made by the platform, lies with the retailer.
listing, including all changes made by the platform, lies with the retailer.
This ruling has far-reaching implications. An unintentional trademark infringement due to an incorrect automatic translation, a misleading product description due to unfortunate formatting, or the absence of a legally required notice – all of this can now fall directly back on the seller. It is no longer sufficient to simply transmit your own product data correctly to the platform. Instead, continuous and active monitoring of the "live" offer, as it is actually displayed to the customer, is absolutely essential.
Safelisting closes precisely this gap. The system monitors not only the transmitted data, but also the content actually displayed on the platform. Through the automated creation of time-stamped screenshots, the status of the offer at a specific point in time is documented without gaps. In the event of a dispute, the retailer thus has reliable evidence and can significantly strengthen their legal position. This form of proactive documentation has become an indispensable tool for effectively reducing liability risks in the algorithm-driven environment of online marketplaces.
Identify and exploit competitive
violations by your competitors
The Unfair Competition Act (UWG) applies to all market participants. Violations by competitors – such as misleading strike-through prices, systematically missing base prices or non-compliance with new product safety requirements – not only deceive consumers, but also give the offender an unfair advantage over law-abiding competitors.
With safelisting, monitoring can be specifically extended to competitors' offers. The system identifies potential competition violations and documents them carefully. This information is valuable for two reasons:
- Position of strength: If a retailer is confronted with accusations from a competitor, the documented knowledge of the competitor's own violations enables a response on equal terms. The retailer is not defenceless, but can point out that the opponent has also violated regulations.
- Active approach: In accordance with the UWG, unfair practices by competitors can be actively warned against and legal action taken to ensure fair market conditions. Anyone who knows that a competitor systematically refuses to indicate the base price or uses prohibited bait pricing can take targeted action against this.
Safelisting automatically informs you of significant deviations and anomalies in the market and enables retailers to act promptly and on the basis of data. Instead of just paying attention to your own behaviour, you become a guardian of the market environment – an advantage that pays off in the long term.
Why even small
pricing errors can
threaten your business?
The complexity of online commerce harbours considerable legal and financial risks, which are often hidden in inconspicuous details of product presentation. A single incorrect price, an incomplete base price indication or an overlooked warning notice can be enough to cause expensive warnings, high fines or a sales ban. Even established retailers are not immune to drastic pricing errors: for example, a standard infusion tube was recently (09/2025) listed on a German online pharmacy platform for over £215 for weeks – while the market price is only £1.50 to £3.50. This increase of up to 14,000% compared to the competition clearly illustrates how easily serious price deviations can go unnoticed. Such outliers are harmful in several ways:
-
Margins and sales
If prices are too low, margins collapse; if prices are extremely inflated, sales fail to materialise.
-
Conversion and customer experience
Excessive prices lead to a drop in conversion rates as customers are deterred by the offer.
-
Trust and reputation
implausible prices undermine buyers' trust in the retailer's professionalism and pricing policy.
-
Marketing expenditure
Advertising budgets are wasted when incorrectly priced products are advertised in adverts, but customers do not buy them because of the price.
Errors are particularly critical on large marketplaces such as Amazon or Google Shopping, which are crucial for many retailers' sales. On these platforms, the retailer sometimes loses control over the final presentation of their offers. Technical transmission errors, automatic content adjustments by the marketplace operator or unnoticed system problems can lead to incorrect listings – and ultimately, the seller is liable for these display errors. Manually checking all of their offers around the
The new General Product Safety Regulation (GPSR) 2024:
A turning point for online commerce
On 13 December 2024, the General Product Safety Regulation (GPSR), a new EU-wide product safety regulation, came into force. It replaces the previous Product Safety Directive and thus also large parts of the German Product Safety Act (ProdSG). The GPSR affects almost all non-food products on the EU internal market and aims to ensure consumer health and safety through stricter and more uniform rules.
The regulation places obligations on the entire supply chain – from the manufacturer to the importer to the retailer. Each link in the chain must ensure that the products placed on the market meet the new, stricter safety requirements. For online retailers, this results in specific and far-reaching obligations that go far beyond the previous requirements.
Specific obligations for online retailers under the GPSR: Under the GPSR, online offers must contain a range of additional information in order to be considered compliant:
- Identification of the responsible person: Each product listing must contain the name and full contact details (address, email) of the manufacturer. If the manufacturer is located outside the EU, the details of a responsible economic operator in the EU (e.g. importer or authorised representative) must be included in the offer.
- Unique product identification: The product must be clearly identifiable. This includes an image of the product and the type, batch or serial numbers or other identification marks.
- Warnings and safety instructions: All relevant warnings and safety instructions must be provided directly in the online offer in a language that is easily understandable for the consumer. A reference to an instruction manual or an external website is not sufficient.
The following comparison highlights some of the key tightening measures in the GPSR compared to the previous legal situation:
- Scope: Previously national implementation (ProdSG in Germany) – now directly applicable EU law, uniform in all Member States.
- Information requirements: Previously, a general obligation to provide safety information – now specific obligations for online offers (manufacturer name, contact details, product ID, warnings directly in the listing).
- Responsibility: Previously, the main obligations lay with manufacturers and importers – now online retailers and marketplaces are also explicitly included in the responsibility.
- Traceability: Previously basic requirements – now stricter requirements to ensure traceability throughout the entire supply chain (e.g. documentation obligations).
- Market surveillance: Previously national authorities with limited powers – now stronger networking of supervisory authorities across the EU and extended powers of intervention (including rapid product recalls, blocking of offers, etc.).
The need for fair and transparent pricing is also underpinned by case law in other digital sectors. For example, the Regional Court of Cologne declared the price increases of streaming provider Netflix in the years 2019 to 2022 to be invalid. The underlying clause in the general terms and conditions allowed price increases but did not provide for any possibility of price reductions – which the court considered to be an unreasonable disadvantage for consumers (Cologne Regional Court, judgment of 15 May 2025, ref. 6 S 114/23). Even though this ruling concerned a subscription service, it sends a clear signal to the entire digital economy: price changes must be based on a transparent and legally sound basis. For online retailers, this means that the documentation of price adjustments, for example for the calculation of discounts, is of particular importance. Only those who keep a clear record of their price history can prove, in case of doubt, that all changes were made fairly and in accordance with the rules.
What are the consequences
of non-compliance and
how does safelisting help?
Non-compliance with the GPSR is not a trivial offence. National market surveillance authorities have extensive powers to sanction violations. The consequences for retailers can be severe, ranging from heavy fines to orders for product repairs or recalls, to the complete suspension of offers or expensive legal proceedings.
Given the sheer volume of products and the dynamic nature of online marketplaces, manual verification of GPSR compliance is virtually impossible for retailers to manage. Safelisting offers a system-supported solution here. The service enables comprehensive and automated verification of product listings for compliance with the new GPSR guidelines. The system can specifically check whether the required information – such as manufacturer name, contact details and product identification features – is available in the offer. In the event of discrepancies or missing information, the retailer is immediately alerted and can take corrective action before the market surveillance authorities take action.
Compliance with GPSR thus not only secures the retailer's legal position, but also strengthens customer confidence in the safety of the products on offer. Those who transparently present all the required information in their offers signal professionalism and diligence.

The pitfalls of the Price Indication Regulation (PAngV)
The Price Indication Regulation (PAngV) forms a central legal framework for retailers in B2C business. Its provisions aim to ensure price clarity and comparability for consumers. However, violations of the PAngV are not only anti-competitive, but also a frequent reason for costly warnings. A ruling by the Federal Court of Justice (BGH) in January 2023 underlines the strict interpretation of the regulation by the courts:
An online retailer offering cat food on Google Shopping was successfully warned by an association for failing to indicate the legally required base price in addition to the total price. The BGH confirmed the legality of the warning letter on the basis of the Unfair Competition Act (UWG) and set the amount in dispute at €10,000 (BGH, judgment of 12 January 2023 – I ZR 111/22). This ruling makes it clear that even seemingly minor omissions in price display can have serious legal consequences.
Key requirements of the Price Indication Regulation (PAngV) – The PAngV sets out precise requirements for the display of prices to end consumers. The most important obligations include:
- Final price information: The full total price including VAT and all other price components must always be stated.
- Basic price information: For goods offered by weight, volume, length or area, a basic price per unit of quantity (e.g. per kg, per litre) must be stated. Since an amendment in May 2022, this basic price must be stated "unambiguously, clearly recognisable and legible", but no longer necessarily in close proximity to the final price.
- Shipping costs: The amount of shipping costs incurred must be communicated clearly and in good time before the order is completed.
- Discount campaigns (Section 11 PAngV): When advertising price reductions, the lowest total price that the retailer has charged for the product within the last 30 days prior to the discount campaign must be stated. This is to prevent misleading inflated prices.
The regulations on discount campaigns under Section 11 PAngV in particular pose major challenges for retailers. Correctly determining and stating the lowest price of the last 30 days requires precise and complete documentation of the retailer's own price history. A current case being heard before the European Court of Justice concerning the price advertising of the discounter Aldi shows how controversial this issue is: essentially, it concerns the question of whether the reference price was correctly stated in a discount campaign. The upcoming ruling could have far-reaching consequences for the entire industry and further tighten the requirements for transparency in discount campaigns.
For retailers, this means that manual monitoring of pricing is no longer sufficient. Safelisting offers crucial support here by automatically archiving and analysing historical price data. This allows the correct reference prices to be accessed at any time in a traceable manner – a double benefit: on the one hand, this minimises legal risks and, on the other hand, it strengthens customer confidence through a transparent pricing policy.
While protection against legal risks is a central function of product monitoring, the potential of systematic market observation goes far beyond this. An intelligent monitoring system such as Safelisting not only serves to reactively prevent errors, but also to proactively strengthen your own market position through strategic competitive analysis and price optimisation.
Understanding marketplace dynamics and optimising pricing strategies
Online retail is characterised by enormous price dynamics. As Amazon emphasised in a recent antitrust case, prices for popular products in German online retail change several times a day, and customers regularly compare offers. A rigid pricing strategy is hardly successful under these conditions – competitive pressure is too high and market conditions are constantly changing.
A 2024 study analysing pricing on German online marketplaces came to some revealing conclusions: 61.1% of suppliers pursue different pricing strategies depending on the marketplace. Pricing is therefore adjusted to the respective competitive situation and fee structure of the platform. It also showed that price levels vary depending on the marketplace: Amazon tends to have stable and mostly lower prices, eBay is more volatile with a tendency towards falling prices, while Kaufland tends to have higher and more stable prices. No marketplace consistently offered the lowest prices – each platform has its own dynamics and customer expectations. In addition, around 63% of Amazon customers compare prices before buying, making competitive price positioning particularly crucial there.
This data shows that a successful pricing strategy requires a deep understanding of the respective platform dynamics. Continuous price monitoring, as enabled by Safelisting, provides the necessary data basis. Retailers can identify which platforms their main competitors are particularly active on, where the biggest price differences exist and which marketplaces have the least price variation. Based on these insights, they can tailor their own pricing strategy to optimise margins without losing competitiveness. Modern repricing systems already use such data and achieve average sales increases of up to 25% through dynamic price optimisation by taking into account competitive activities, demand forecasts and stock levels in real time. Responding to price signals at an early stage not only helps avoid mistakes, but also allows retailers to actively shape the market in their favour.
The path to a secure market position: proactive action is crucial
The sum of the legal requirements, the dynamics of the marketplaces and the potential financial damage caused by errors make it clear that a reactive approach is no longer sufficient in online retail. Waiting until a warning letter arrives or an authority launches an investigation is a risky strategy – one that, in the worst case, can jeopardise the existence of the company. The key to sustainable success lies in proactive risk management.
Safelisting from PREISmonitoring acts as such a proactive early warning system. It offers a reliable solution for efficiently and automatically monitoring price deviations and incorrect product descriptions. The advantages of this approach can be summarised as follows:
-
Real-time error detection:
The system identifies pricing errors, missing base prices or other discrepancies within a very short time, and thus tends to do so before they lead to financial losses or legal consequences.
-
Compliance security:
Safelisting continuously monitors the conformity of offers with the PAngV and the new GPSR. Retailers are immediately warned of possible violations (e.g. missing information or warnings). This minimises the risk of warnings, fines and sales bans.
-
Legally compliant documentation:
Automatically generated screenshots with timestamps document the exact status of each product listing. In the event of a dispute – for example, regarding liability for content generated by the platform – retailers have reliable evidence and can significantly strengthen their legal position.
-
Strategic market advantage:
Monitoring the competition reveals unfair practices by competitors and provides valuable data for optimising your own pricing strategy. Retailers gain market transparency: they can see how competing offers are positioned and can adjust their pricing and offering strategy based on data. Monitoring thus becomes a tool for actively securing and expanding market share.
Implementing such a system is an investment in the stability and future security of the business. Safelisting not only protects against the immediate financial consequences of mistakes, but also secures the company's reputation and market position. At a time when customer trust and compliant behaviour determine success or failure in e-commerce, a proactive monitoring concept provides a decisive advantage. Take the next step now: protect your online business before mistakes occur. Take advantage
Complete transparency as the
basis for informed decisions
Complete transparency is the foundation for making confident and well-informed decisions in online retail. Only those who have a clear view of their own product listings, price developments and market movements can identify risks at an early stage and respond in a targeted way. Safelisting creates exactly this level of visibility by continuously monitoring relevant product and pricing data across marketplaces.
Instead of relying on assumptions or delayed manual checks, retailers gain a reliable, data-based overview of what is happening in the market at any given time. This makes it easier to detect anomalies, assess competitive developments and take action based on facts rather than guesswork.
- Full market visibility: Gain a clear overview of your own offers, competitor activity and relevant price movements across marketplaces.
- Better decision-making: Use reliable data to assess risks, identify opportunities and optimise your pricing and listing strategy.
- Faster response times: Detect deviations and changes early so you can act before they affect sales, compliance or customer trust.
