DSA vs P2B Regulation platform safety and business-user fairness compared

The DSA has applied generally since 17 February 2024 and applies by service role: intermediary services, hosting services, online platforms, online marketplaces, and online search engines have different layers of duties. It covers providers established outside the EU when they offer services in the Union through a substantial connection; mere technical accessibility from the EU is not enough. A marketplace or app store may need trader traceability, notice-and-action, statements of reasons, internal complaint handling, advertising transparency, recommender explanations, and transparency reporting depending on the service features and size.

For very large online platforms and very large online search engines, the DSA adds risk governance. The Commission source and the regulation both tie this category to services with at least 45 million average monthly active recipients in the EU and to Commission designation, after which enhanced duties such as systemic risk assessment, mitigation, audit, data access, and ad repository work become central.

The P2B Regulation has applied since 12 July 2020 and is narrower than the DSA in subject matter. It applies to providers of online intermediation services and online search engines where business users or corporate website users established or resident in the EU offer goods or services to consumers located in the EU. The provider itself does not need to be established in the EU. Review the platform's business terms, ranking practices, restrictions, data explanations, and complaint channels for transparency and fairness toward those business users.

P2B does not apply to online payment services, online advertising tools, or online advertising exchanges when they are not provided to initiate direct transactions and do not involve a contractual relationship with consumers. A business-only tool also falls outside the online-intermediation definition if it does not let business users offer goods or services to consumers. Test those elements before treating every seller, advertising, payment, or search tool as a P2B service.

P2B evidence is therefore commercial-policy evidence: terms and conditions, change notices, restriction and suspension reasons, ranking explanations, differentiated-treatment explanations, data-access explanations, complaint records, mediation information, and business-user communications. Proposed terms changes normally require notice on a durable medium at least 15 days before implementation, with a longer period when business users need technical or commercial adaptations. Legal or regulatory obligations and unforeseen imminent dangers such as fraud, malware, data breaches, or other cybersecurity risks can displace that notice period.

Restriction or suspension of individual goods or services requires reasons on a durable medium before or when the action takes effect. Terminating the whole service normally requires reasons at least 30 days in advance, subject to Article 4 exceptions such as a legal obligation, an imperative reason under applicable national law, or repeated infringement of the terms. Article 11 internal complaints and Article 12's requirement to identify at least two mediators do not apply to providers that are small enterprises under Recommendation 2003/361/EC.

Overlap is common for marketplaces, app stores, travel platforms, accommodation platforms, and search services. The same platform may moderate listings under the DSA, verify traders under DSA marketplace rules, publish ranking parameters under P2B, and explain recommender systems under the DSA. Reuse shared facts, but label which legal question each record answers.

A useful evidence split is: DSA proves safety, moderation, transparency, marketplace, and risk-governance duties; P2B proves transparent and fair treatment of business users. If a restriction affects both a user-facing listing and a business account, keep both explanations: the DSA record for the content or service restriction and the P2B record for the business-user relationship.

DSA supervision runs through Digital Services Coordinators and the European Commission, with direct Commission supervision and enforcement powers for VLOPs and VLOSEs. The DSA regulation also sets maximum fine levels for Commission enforcement against very large services, including fines up to 6 percent of worldwide annual turnover for infringements of relevant DSA provisions.

P2B enforcement is structured differently. The P2B Regulation requires Member States to ensure adequate and effective enforcement and allows qualifying organisations, associations, and public bodies to bring court actions to stop or prohibit non-compliance. Treat that as a separate escalation route from DSA regulator engagement.
