P2B dispute resolution for sellers: what changed and what to do

TL;DRThe EU Platform-to-Business (P2B) Regulation gives sellers on Amazon DE and other covered marketplaces a set of enforceable procedural rights when a platform restricts, suspends, or terminates their account. Those rights include an obligation on the platform to explain its decision, maintain an internal complaint-handling system, and offer access to mediation. A suspension under these rules is not final until those paths have been used – and the question for most sellers is whether they are using them correctly.

If you sell on Amazon DE and you have received a suspension or delisting notice that feels immovable, the regulatory machinery that surrounds that notice may give you more room to maneuver than the notice itself suggests. As EU marketplace enforcement has matured, the gap between what the rules require platforms to do and what sellers actually understand about those requirements has widened. That gap is where most disputes are lost.

This briefing covers what P2B dispute resolution actually means on Amazon DE, the realistic procedural sequence, the decision points a seller faces at each stage, and what remains genuinely uncertain under current enforcement practice.

What the P2B Regulation actually obliges Amazon DE to do for sellers

The Platform-to-Business Regulation – Regulation (EU) 2019/1150, in force since July 2020 – places a series of procedural obligations directly on platforms that operate as intermediation services for business users in the EU. Amazon DE is a covered platform. The obligations are not discretionary guidelines; they are binding legal requirements.

At their core, the obligations work like this. When Amazon restricts or suspends a seller's access, or terminates the seller's account, it must provide a statement of reasons setting out the specific facts and circumstances that justified the decision. For suspensions, the statement must be given before the restriction takes effect, or immediately where prior notice is not possible. For terminations, the platform must give at least 30 days' notice in ordinary circumstances.

Beyond the statement of reasons, Amazon is required to maintain an internal complaint-handling system that is accessible to all business users free of charge, and to handle complaints transparently and promptly. It must publish, in its terms and conditions, at least two mediators it is willing to engage with to attempt out-of-court resolution of disputes with business users. Mediation is not mandatory – either party can decline to proceed – but the offer must exist, and the platform must act in good faith in any mediation that is initiated.

What this means practically is that a seller facing an Amazon DE suspension has a procedural checklist that the platform must satisfy, and a formal complaint path that exists independently of the ordinary Seller Central appeal flow. In matters we handle, sellers frequently arrive having used only the Seller Central appeal route, unaware that the P2B internal complaint channel is a separate and differently-staffed mechanism. The distinction matters because the internal complaint system is subject to regulatory scrutiny in a way that an informal appeal response is not.

How does the Digital Services Act change the picture for suspended sellers?

The Digital Services Act (DSA) – which designates Amazon as a Very Large Online Platform (VLOP) – adds a second layer of procedural rights on top of P2B, and the two regimes overlap in ways that create real leverage for sellers who know how to use them together.

Under the DSA, VLOPs must provide an internal complaint-handling mechanism for any user whose content or account has been subject to a restriction decision. The mechanism must be effective, easy to access, and allow the complainant to provide information the platform may not have considered. Decisions made through this system must be reversible if the original decision was wrong. The DSA also requires VLOPs to offer access to certified out-of-court dispute resolution bodies for disputes that were not resolved internally – a requirement that runs parallel to, but is distinct from, the P2B mediation obligation.

For a seller on Amazon DE, this means that a single suspension event may trigger rights under both the P2B Regulation and the DSA. The procedural paths do not automatically merge, but they can be run in coordination. We regularly see situations where a P2B internal complaint, drafted with explicit reference to the DSA statement-of-reasons requirement, produces a more substantive response from the platform than either route would have generated alone.

The Digital Markets Act (DMA) is a third instrument in play where the dispute touches on Amazon's conduct as a gatekeeper – for example, where a seller alleges differential treatment in ranking or access to data. DMA claims are more complex and typically require a regulatory-enforcement framing rather than a direct seller complaint, but they are not irrelevant background. For a broader account of how these instruments interact, see our page on Amazon as a Very Large Online Platform – what changed and what to do.

What is the realistic procedural path for a seller on Amazon DE?

The realistic path from a suspension notice to a resolution is longer and more structured than most sellers expect. It has four recognizable phases, and the seller's decisions at each phase shape what is still available later.

Phase 1: Statement of reasons and the Seller Central response. The first step is to obtain and analyze the statement of reasons. This sounds obvious, but in practice the statement Amazon provides in its suspension notice is often brief, and the seller's task at this stage is to determine whether it satisfies the P2B requirement – that is, whether it specifies the actual facts and circumstances, or whether it is a templated response that does not. If it does not, the seller has an immediate procedural ground to raise, separate from the merits of the underlying complaint.

Any response filed through Seller Central at this stage is part of the record. A poorly drafted appeal – one that concedes facts, offers vague corrective promises, or misidentifies the root cause – limits what can be argued later in the internal complaint or mediation phase. This is the stage where the framing of the dispute is set.

Phase 2: The P2B internal complaint. If the Seller Central response does not produce a satisfactory outcome, the seller can file a formal complaint through Amazon's P2B internal complaint-handling system. This is a distinct mechanism from the ordinary appeal. It must be handled by a dedicated team, and the platform must consider it on its merits and provide a meaningful response. Filing this complaint creates a formal record under a regulated process, which is a different evidential position from an unanswered Seller Central message thread.

Phase 3: Mediation. If the internal complaint does not resolve the dispute, the seller can request mediation with one of the mediators Amazon has listed in its business terms. Mediation under P2B is voluntary – Amazon can decline – but a documented request, followed by a platform refusal to engage in good faith, is itself potentially relevant to any subsequent regulatory or legal action. In our practice, the existence of a formal mediation request has more than once prompted a substantive re-engagement from the platform that the internal complaint alone had not.

Phase 4: Regulatory complaint and further options. Where the platform has failed to satisfy its P2B obligations – by, for example, not providing an adequate statement of reasons, or by failing to respond to the internal complaint within a reasonable period – the seller may have the basis for a complaint to a competent enforcement authority. P2B enforcement in the EU is handled at member-state level. In Germany, relevant authorities include competition and market supervisory bodies. A regulatory complaint is not a quick fix, but it creates external pressure and produces a further record. The DSA adds the option of certified out-of-court dispute settlement through a DSA-approved body, which operates on its own timeline and procedural rules.

What are the seller's decision points and trade-offs?

Running through the full P2B sequence takes time, and sellers on Amazon DE are typically dealing with a live commercial problem – listings down, inventory tied up, disbursements stopped. The regulatory route is not designed for speed. That tension is real, and it shapes every decision.

The first decision is whether to run the Seller Central appeal and the P2B internal complaint simultaneously or sequentially. In many matters, running them simultaneously is appropriate: the appeal keeps the Seller Central channel open, while the internal complaint creates a parallel formal record. The risk of simultaneous filing is inconsistency – if the appeal and the complaint make different factual claims, that inconsistency will be visible to whoever reviews them. Drafting both tracks from the same factual foundation, with consistent framing, is essential.

The second decision is whether to request mediation at all, and when. Mediation costs the seller time and imposes a procedural step on the platform. It is most useful where the underlying dispute involves a fact question that is genuinely arguable – product authenticity, authorization status, account history – and where the seller has evidence the platform may not have fully considered. It is less useful where the suspension turns on a policy rule that is being applied correctly and the seller's real problem is the policy rather than its application.

The third decision is whether to engage regulatory channels. This is a longer-game move. A P2B regulatory complaint will not reopen an account next week. What it may do is strengthen a seller's position in a parallel civil or commercial dispute, create a record that supports future claims, and – in patterns where similar sellers are affected by similar conduct – contribute to enforcement scrutiny that produces broader change. Sellers with significant business on Amazon DE, facing what looks like a structural rather than a one-off problem, should weigh this option seriously.

What about the myth that EU sellers have no leverage once a platform suspends them? That framing is not accurate. The P2B Regulation, the DSA, and in gatekeeper disputes the DMA, collectively create a procedural and substantive structure that platforms must respect. That structure is not a guarantee of reinstatement. It is a set of enforceable obligations that, when used correctly, change the balance of a dispute. The practical effect depends entirely on whether the seller – or the seller's legal advisor – understands the regime well enough to invoke it properly.

What remains genuinely uncertain in P2B enforcement

Several aspects of P2B enforcement on Amazon DE remain unsettled in practice, and sellers and their advisors should plan with that uncertainty in mind.

The standard for what constitutes an adequate statement of reasons is not precisely defined in the text of the regulation or in published guidance. Amazon's notices vary in their specificity, and whether any given notice satisfies the P2B requirement is a judgment call. Enforcement authorities and courts in different member states have not yet produced a consistent body of decisions on this question. In our practice, we treat this as a live issue in every matter and assess the notice against the regulatory standard before advising on the appropriate response.

The mediators listed in Amazon's P2B terms operate under their own rules and timelines. The procedural experience of using P2B mediation varies, and the practical effectiveness of mediation as a resolution mechanism depends heavily on how the referral is framed and what evidence the seller brings to it. Sellers who approach mediation as an administrative step rather than as a substantive proceeding consistently achieve less.

The relationship between the P2B internal complaint system and the DSA's internal complaint-handling mechanism is also not fully resolved. Platforms may treat them as a single merged system, or as distinct tracks with different procedural rules. For sellers on Amazon DE, we check how Amazon's current published terms describe each mechanism and advise on which track to use, or whether to use both, depending on the specific facts.

DSA out-of-court dispute settlement through certified bodies is a newer mechanism, and the operational experience with these bodies in marketplace disputes is still developing. The timelines, evidential standards, and practical outcomes of DSA out-of-court settlement are genuinely uncertain at this stage. We monitor developments and advise sellers on whether referral to a DSA-certified body is the right tool for their specific situation.

One element that is not uncertain: a seller who does nothing – who accepts the suspension as final, moves on, and abandons the regulatory record – forfeits rights that the regulation specifically created for them. That forfeiture is irreversible once the relevant procedural deadlines pass.

A worked example: when the procedural record changes the outcome

A consumer electronics seller operating on Amazon DE (winter 2025) came to us after receiving a suspension notice that cited a product safety complaint. The Seller Central appeal had been rejected twice. The seller's instinct was that the underlying complaint was unfounded but that there was nothing left to do. We reviewed the suspension notice and identified that the statement of reasons did not specify which product, which listing, or which complaint had triggered the decision – it was a templated notice that did not satisfy the P2B particularity requirement.

We drafted a P2B internal complaint that identified this deficiency specifically, attached the seller's product certification documentation, and requested a fully particularized response under the regulation's requirements. The response that came back identified the actual product and the specific complaint for the first time. That specificity allowed us to address the real issue directly in a supplementary filing. The account was restored. We do not claim this outcome is typical or guaranteed – what we can say is that the deficiency in the original notice, and the seller's right to raise it through the internal complaint channel, would never have been used if the matter had been treated as a standard Seller Central appeal.

A second example: an apparel brand on Amazon DE (summer 2026) was facing a repeated delisting of multiple ASINs on the basis of intellectual-property complaints. The internal complaint produced a response, but the platform's explanation was that it could not intervene in the IP dispute itself. We assessed the DSA statement-of-reasons obligation and the P2B mediation track in parallel, and prepared a mediation request that framed the issue as a failure of the platform's complaint-handling process rather than the underlying IP merits. The mediation produced a structured re-review of the affected ASINs against clearer factual criteria. Several listings were reinstated. For a closer look at how one seller's experience of DMA gatekeeper provisions shaped a similar strategy, see our analysis on how one seller resolved DMA gatekeeper obligations and sellers.

What should a seller on Amazon DE do right now?

If you are facing a suspension, restriction, or repeated delisting on Amazon DE, the practical steps are sequenced. None of them should be skipped, and the sequence matters because each phase builds on the record from the prior one.

• Obtain and preserve the full suspension notice, any Seller Central communications, and all prior appeal responses. Document dates.
• Assess whether the statement of reasons in the notice specifies the actual facts and circumstances or whether it is a generic templated response. If it is generic, that is the first ground to raise.
• Determine which internal complaint channel to use – the P2B internal complaint mechanism, the DSA internal complaint-handling mechanism, or both – based on the nature of the restriction and the platform's current published terms.
• Draft the internal complaint as a formal regulatory submission, not an appeal. Identify the specific P2B or DSA obligations the platform has not satisfied, and attach any evidence the platform did not have or did not address in its prior responses.
• Assess whether mediation is appropriate at this stage or whether additional internal complaint steps should be completed first. Do not request mediation as a default – assess whether it fits the specific facts of the dispute.
• Consider whether the pattern of conduct suggests a structural issue that warrants a regulatory complaint, either now or after the internal complaint process is complete.

The steps above describe the standard path. Your situation turns on the exact wording of the notice, the account history, the nature of the underlying complaint, and the timing – which is what we review first in every matter we take on. To get a read on your position, email info@tutamenlaw.com.

Frequently asked questions

How long does resolving P2B dispute resolution for sellers usually take on Amazon DE?

There is no fixed timeline that applies to all P2B disputes. The internal complaint phase should, under P2B requirements, produce a meaningful response within a reasonable period, but the regulation does not set a specific number of days. In practice, the internal complaint phase varies from several weeks to longer, depending on the complexity of the underlying issue and how the complaint is framed. Mediation adds further time. Sellers should plan for a process that runs in parallel with, not instead of, the ordinary Seller Central appeal track. Acting quickly at each phase – particularly in filing the initial internal complaint – preserves the most options.

What are the main risks if I handle P2B dispute resolution for sellers alone?

The primary risk is procedural: sellers who handle their own P2B complaints frequently use the internal complaint channel as an informal re-appeal rather than as a formal regulatory submission. This means they do not identify the specific P2B obligations the platform has failed to satisfy, do not frame the complaint in the language of the regulation, and do not preserve the record in a way that supports later stages. A second risk is inconsistency – making factual claims in the P2B complaint that contradict earlier Seller Central appeals, which the platform will notice and use. A third risk is missing the mediation window or misunderstanding which mediators are relevant under the current platform terms.

Do I need a lawyer for P2B dispute resolution for sellers?

You are not required to use a lawyer. The P2B internal complaint and mediation processes are designed to be accessible to sellers without legal representation. Whether legal help is worth the cost depends on the size of the suspended business, the complexity of the underlying complaint, and how many prior attempts have already failed. Where a Seller Central appeal has been rejected more than once, or where the suspension involves an IP complaint, a product safety allegation, or a related-account flag, the procedural and drafting precision that a specialist brings typically changes the quality of the submission in ways that matter to the outcome. Our fees are fixed and quoted up front after a short review, so the cost question is answerable before committing.
