P2B dispute resolution for sellers: a seller's checklist

TL;DRThe Platform-to-Business (P2B) Regulation gives EU-based marketplace sellers a set of procedural rights that apply directly on Amazon DE – including the right to an explanation of any restriction or suspension, access to an internal complaint-handling system, and, ultimately, access to mediation. A suspension under EU rules is not automatically the end of the road. This checklist walks through the phase-by-phase steps that matter: from reading the notice correctly through to deciding whether mediation is worth pursuing. Each phase contains concrete checks you can act on immediately.

This page covers Amazon DE as the primary surface, though the same P2B framework applies across EU marketplaces. The goal is to give you a structured view of the procedural path so that each decision point is clear before you reach it – not after.

Phase 1: What is P2B dispute resolution for sellers, and why does it exist on Amazon DE?

The P2B Regulation (EU Regulation 2019/1150 on promoting fairness and transparency for business users of online intermediation services) creates binding obligations on platforms like Amazon DE toward their seller base. It is not a voluntary scheme. Amazon, as a major online intermediation service operating in the EU, must comply whether or not its contractual terms say otherwise.

The core rights for sellers are practical. When Amazon restricts, suspends, or terminates a seller account, it must provide a statement of reasons – a specific explanation of the factual or policy grounds for the action. The platform must maintain an internal complaint-handling system that is accessible, effective, and based on the principles of transparency and equal treatment. Sellers may also refer unresolved disputes to mediators from a list the platform is required to maintain and fund. These are not grace-period protections. They are live, enforceable EU obligations.

In matters we handle, sellers often arrive without having used any of these mechanisms – because the path was not obvious from the suspension email itself. The practical reality is that Amazon DE's seller-facing communications do not always label the P2B route explicitly. Knowing it exists, and knowing when to invoke it, is the first check on this list.

Checklist – Phase 1 checks:

• Confirm the account is registered as a business seller on Amazon DE (or another EU Amazon marketplace). P2B applies to business users, not private sellers.
• Identify the specific action Amazon has taken: restriction of a listing, suspension of the account, or notice of termination. Each triggers different P2B obligations.
• Check whether a statement of reasons was provided. If not, you have grounds to request one immediately under the P2B Regulation.
• Note the date of the notice. Timelines under P2B and under the Amazon Business Solutions Agreement (BSA) may both be running simultaneously.
• Locate the relevant Amazon DE complaint and appeals channels in Seller Central. These are the access points for the internal complaint-handling system Amazon is obliged to operate.

The P2B framework and the DSA's statement-of-reasons requirement overlap on VLOP-designated platforms. Our guide to EU marketplace regulation for sellers covers how the two regimes interact in practice.

Phase 2: How do I read the suspension or restriction notice correctly?

The notice is the starting document, and reading it wrong is the single most common reason a P2B complaint or appeal fails at the first stage. Not every notice is the same: an account-level suspension citing safety policy is a different legal and commercial problem from a listing restriction citing IP rights.

The statement of reasons Amazon is required to provide under Article 4 of the P2B Regulation must set out the specific facts or circumstances, the grounds under its terms of service, and – for terminations – advance notice of at least 30 days unless the platform falls under a limited exception. If the notice omits the factual grounding entirely, or simply quotes a policy reference without explaining how it applies to your specific account, that is itself a P2B compliance issue you can raise in the internal complaint-handling process.

We regularly see sellers treat a vague notice as a dead end. It is not. A notice that lacks the required specificity creates a procedural opening: the seller can formally request the missing statement of reasons, and that request starts a paper trail that matters if the matter proceeds to mediation.

Checklist – Phase 2 checks:

• Read the notice in full and identify: (a) the specific policy cited; (b) the specific conduct or listing attributed to your account; (c) whether any advance notice period was stated.
• If the notice cites a termination without 30 days' notice, identify whether Amazon has claimed an exception (e.g., legal obligation, threat to consumers). If no exception is stated, this is a procedural breach to record.
• Check whether the factual basis is accurate. A notice that cites "inauthentic goods" when you hold valid supply chain documentation is factually challengeable, not just procedurally challengeable.
• Save the notice, the email headers, and the Seller Central notification in your records. Mediation and complaint processes require documentary evidence of what was communicated and when.
• Identify whether the notice covers one ASIN, a category, or the entire account. The scope determines which complaint path is proportionate.

Getting this phase right is closely connected to understanding how Amazon's obligations as a Very Large Online Platform under the Digital Services Act reinforce P2B rights. Our page on handling Amazon as a VLOP on Amazon FR explains the DSA/P2B overlap from the seller's side.

Phase 3: How does the internal complaint-handling process actually work?

Amazon's internal complaint-handling system, required under Article 11 of the P2B Regulation, is the mandatory first step before mediation becomes available. It is not the same as a standard Seller Central appeal or a Plan of Action (POA). Understanding the distinction matters, because submitting a generic POA when you should be filing a P2B internal complaint can exhaust your first-stage options without engaging the rights the regulation gives you.

The internal complaint-handling system must be free of charge, accessible directly by the business seller, and capable of addressing complaints about four categories of issue: alleged non-compliance with the platform's obligations under P2B; technology issues that directly affect the seller; measures taken by the platform that directly affect the seller; and the platform's conduct in relation to its ranking practices and data access. A suspension complaint falls squarely into the third category.

In matters we have reviewed, the practical path through the internal system often requires framing the complaint explicitly in P2B terms – not just in terms of the Amazon policy that was cited. A complaint that identifies the specific P2B obligation the platform has allegedly failed to meet is harder to dismiss with a template response than a generic appeal.

There is also a DMA dimension worth noting for Amazon DE specifically. The Digital Markets Act imposes gatekeeper obligations on Amazon in its capacity as a core platform service. Our step-by-step guide on handling DMA gatekeeper obligations as a seller covers how P2B and DMA arguments can be combined where appropriate.

Checklist – Phase 3 checks:

• Identify the specific complaint channel in Seller Central that corresponds to the internal complaint-handling system, rather than the standard case log or appeals queue.
• Frame the complaint with explicit reference to the P2B Regulation and the specific Article you believe has not been complied with. Vague complaints receive vague responses.
• State the commercial impact of the restriction or suspension – the inventory held in FBA, the disbursement cycle affected, the listings taken down – because proportionality arguments in mediation turn on documented harm.
• Request a response in writing and within a specific time window. P2B requires the system to be effective; a response that is indefinitely delayed is itself a deficiency you can document.
• Keep a log of every submission, reference number, and response. If the matter proceeds to mediation, the mediator will need to see the internal complaint trail.
• Assess the response when it arrives: did it engage with the specific P2B grounds you raised, or is it a template? A template response that ignores your specific grounds strengthens the case for escalation.

A mid-size homewares seller on Amazon DE (winter 2026) came to us after receiving a suspension notice that cited a product safety policy without any reference to a specific ASIN or test result. We assisted in framing a formal P2B internal complaint that identified the absence of a factual basis, requested the full statement of reasons, and documented the FBA inventory exposure. Amazon DE provided a revised statement identifying the specific ASIN and the product category concern. The seller was then able to respond to the actual ground rather than to a generic policy citation, and the restriction was confined to a single listing rather than the account.

Phase 4: What are the seller's decision points before mediation?

Mediation under the P2B Regulation is not automatic. The seller initiates it, chooses from the mediators Amazon is required to identify, and bears none of the mediation costs – the platform must fund mediation fully. That last point is significant: the cost asymmetry that makes formal dispute resolution inaccessible in most commercial contexts does not apply here.

But mediation is not always the right next step. The decision tree has several branches, and the wrong choice at this point can consume weeks without commercial result. The checks below map the main decision points.

If the internal complaint produced a satisfactory outcome – the restriction was lifted, the correct ASIN was identified, the erroneous termination was reversed – mediation is not needed. Document the resolution and move on. If the internal complaint produced a partial outcome – some listings restored, but others still restricted without adequate explanation – mediation is worth assessing, because a partial resolution that leaves unresolved items on the table may signal a pattern.

Where the internal complaint produced no response, a template response, or a final rejection that does not engage with the P2B grounds raised, the case for mediation is stronger. The seller has evidence of the platform's conduct, a documented complaint trail, and a clear factual dispute about whether the P2B requirements were met.

What does mediation actually achieve? It can produce a binding agreement between the seller and the platform. It does not produce a court order or force account reinstatement by law. Its leverage comes from the platform's reputational and regulatory incentive to resolve documented P2B disputes before they escalate to national enforcement authorities – such as courts or the competent authority in the relevant EU member state.

Checklist – Phase 4 checks:

• Assess the internal complaint outcome: full resolution, partial resolution, no engagement, or final rejection? Each maps to a different next step.
• Locate Amazon's list of identified mediators. Under Article 12 of the P2B Regulation, Amazon must make this list public and keep it current.
• Assess whether the dispute is primarily factual (e.g., no actual policy breach occurred, the wrong account was flagged) or primarily procedural (e.g., no statement of reasons was provided, the 30-day notice period was not given). Factual disputes tend to be more productive in mediation; procedural breaches may also create grounds for national enforcement referral.
• Consider whether the commercial stakes justify the time investment. A single-ASIN restriction worth a small amount of monthly revenue may not warrant the full mediation path; an account-level suspension that has frozen FBA inventory and a rolling disbursement balance almost certainly does.
• Check whether any other EU regulation intersects with the P2B complaint. A suspension that also involves a GPSR product safety issue, an EPR registration gap, or a DSA statement-of-reasons deficiency may support a broader complaint strategy.
• Decide whether to proceed to mediation independently or with legal representation. Mediation is a structured process; the platform will typically attend with its own advisers. An unrepresented seller who has not framed the P2B grounds correctly from Phase 1 onward may find the mediator's ability to assist is limited.

Phase 5: What happens after mediation, and what escalation paths remain?

Mediation under P2B is confidential. If it produces a settlement, neither party is obligated to make the terms public, and Amazon will typically require confidentiality as a condition. That is a practical trade-off: the seller recovers the commercial position or obtains certainty, but the resolution does not create a precedent visible to other sellers.

If mediation does not produce a resolution – either because the mediator cannot bridge the positions or because Amazon declines to engage in good faith – the seller still has escalation options. These depend on the jurisdiction, the nature of the dispute, and the specific EU instrument engaged.

National enforcement. The P2B Regulation is enforced by EU member states. In Germany, relevant enforcement authority may sit with courts (the regulation allows business associations and public bodies to bring court actions on behalf of sellers) or with competent national bodies. A documented P2B breach can support a complaint to the relevant authority, particularly where the breach is systematic rather than a one-off error.

DSA and DMA routes. Where Amazon is acting in its VLOP capacity, the Digital Services Act's statement-of-reasons requirements apply in parallel. The Digital Services Coordinators in each member state have powers under the DSA that are distinct from P2B enforcement. The DMA's gatekeeper obligations provide a further lever for structural disputes about access and ranking – particularly where the suspension pattern suggests Amazon is favoring its own retail operation over third-party sellers.

Civil litigation. P2B does not displace civil remedies. A seller with a well-documented case of non-compliance can pursue injunctive relief or damages through the German courts. This is a more significant step, and the costs and timelines must be weighed against the commercial outcome. For most sellers, mediation combined with national enforcement referral represents a proportionate and faster path.

Checklist – Phase 5 checks:

• Record the outcome of mediation in writing, whatever it is. A failed mediation is still a document that evidences the dispute history.
• If mediation failed or was refused by the platform, assess whether the P2B breach is suitable for a national authority complaint. The key question: is the breach an isolated fact or a systematic practice?
• Where DSA or DMA grounds were present from the outset, assess whether those complaints were separately filed during the internal complaint phase or need to be initiated now.
• For account-level suspensions with frozen FBA inventory, confirm whether the funds-hold position is being maintained by Amazon independent of the P2B dispute. A parallel claim for disbursement of held funds may need to run alongside the P2B complaint rather than waiting for it to resolve.
• Evaluate litigation only if the documented loss and the strength of the P2B breach make the cost-benefit calculation positive. For most mid-market sellers, the mediation and enforcement route is the better first path.
• After any resolution – full, partial, or failed – conduct a compliance audit of your own account to reduce the risk of recurrence: supply chain documentation, product safety certifications, EPR registrations, and any open IP complaints on the account.

An electronics accessories brand selling on Amazon DE (spring 2025) came to us after a full account suspension following a product safety complaint from a competitor. The internal appeal in Seller Central had been rejected twice without any factual explanation of which product line triggered the concern. We worked through the P2B complaint process, identifying the absence of a statement of reasons as the primary breach, and escalated to the mediation stage. Amazon DE produced a statement of reasons that identified a single ASIN tied to a CE marking documentation gap. The account was partially restored while that ASIN remained under review. The seller used the interim period to obtain the missing documentation and submitted it directly. The suspension was fully lifted.

If you have already been through the internal Seller Central appeals process and received only template responses, that is exactly the point at which P2B escalation often produces a different result. To get a read on where your matter stands, email info@tutamenlaw.com for a confidential review.

Phase 6: When should I involve a lawyer, and what does that involvement actually look like?

The honest answer is: earlier than most sellers think, and not just at the point of crisis. The P2B process rewards preparation. A seller who enters the internal complaint phase with a correctly framed complaint, documented commercial harm, and a clear factual record is in a materially stronger position than one who begins the formal process without that groundwork.

There is a persistent myth that EU sellers have no real leverage once a platform like Amazon DE has suspended them. That is wrong. The P2B Regulation, the DSA statement-of-reasons requirement, and the DMA gatekeeper obligations all create enforceable rights that the platform is required to respect. The question is not whether leverage exists – it does – but whether it is being used correctly and in the right sequence.

Attorney involvement in a P2B dispute typically looks like this: a review of the suspension or restriction notice to identify the applicable legal grounds and assess the strength of the P2B complaint; assistance in framing the internal complaint and any formal request for a statement of reasons; preparation for mediation if the internal process does not resolve the matter; and, where appropriate, advice on national enforcement referral or civil litigation options. The work is attorney-led, confidential, and scoped to the specific matter.

Tutamen's fees for EU marketplace regulation work are fixed and quoted up front after a short review of the notice and the account position. There is no open-ended retainer required for an initial review. For matters that are straightforward – a single-listing restriction where the P2B grounds are clear – the scope and cost are correspondingly limited.

Checklist – Phase 6 checks:

• Before filing anything formally: has the notice been reviewed by someone who knows the P2B Regulation and can assess whether a P2B obligation has actually been breached?
• Is the commercial exposure – FBA inventory, disbursement hold, lost listing revenue – substantial enough to warrant professional scoping? For most account-level suspensions, the answer is yes.
• Has any previous appeal or complaint already been submitted? If so, what exactly did it say? A badly framed first submission can make the second harder; a lawyer's review of what was previously filed is often the starting point.
• Is there an active timeline running? DSA statement-of-reasons requests have response obligations attached. The 30-day P2B termination notice requirement, where it applies, is already a clock. Do not let procedural deadlines pass while assessing whether to get help.
• Is the dispute isolated to Amazon DE, or does it involve other EU marketplaces (Amazon FR, Amazon IT, Amazon ES)? A multi-surface dispute has different strategic considerations and may benefit from coordinated handling.

Common P2B mistakes that cost sellers their best opportunity

The seller who handles a P2B dispute alone most often loses not because the underlying case was weak, but because the procedural opportunity was used up before it was properly engaged. These are the patterns we see most often.

Filing a standard POA when the P2B internal complaint process is the right route. A Plan of Action is a reinstatement mechanism under the BSA. It is not a P2B complaint, and submitting one does not engage the platform's Article 11 obligations. The two routes are different instruments serving different purposes.

Accepting a vague response as final. The P2B Regulation requires the internal complaint-handling system to be effective. A response that repeats the original policy citation without engaging the specific grounds raised is not an effective response. Sellers often stop here because the response looks authoritative. It may not be.

Missing the statement of reasons step entirely. Where Amazon has not provided a statement of reasons that meets the Article 4 standard, formally requesting it is both a right and a strategic move. It forces the platform to commit to a specific factual ground, which is the basis for everything that follows.

Waiting too long. The P2B and DSA complaint processes interact with disbursement cycles and FBA inventory removal timelines. An account that has been suspended for several months may have inventory that is being disposed of or returned at the seller's cost. Getting into the process quickly limits the collateral damage.

Conflating P2B and BSA arbitration. The BSA dispute-resolution path depends on the version of the agreement that applies to the account, and the path it creates is a separate instrument from P2B mediation. Both may be available; they are not the same thing, and the right choice depends on the specific dispute. We check the applicable BSA version at the outset of every EU matter.

Frequently asked questions about P2B dispute resolution on Amazon DE

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

Timelines vary considerably depending on the complexity of the dispute and which stage is reached. An internal complaint that produces a response and resolution from Amazon DE can resolve in several weeks. Where the internal process is exhausted and mediation is needed, the overall timeline extends to several months in most matters. National enforcement routes take longer still. The P2B Regulation requires the internal complaint-handling system to handle complaints within a reasonable time, but does not fix a binding number of days for every category. Getting the internal complaint framed correctly from the outset is the most reliable way to keep the timeline as short as possible.

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

The most common risk is using up the best procedural opportunity before it has been properly engaged. Filing a standard reinstatement appeal instead of a P2B internal complaint, or accepting a template response as a final answer, forecloses options that were available at an earlier stage. Mediation also requires the seller to have built a credible factual and legal record during the internal complaint phase. A seller who arrives at mediation without that record is in a weaker position. The P2B process is sequential: each phase depends on the one before it being handled correctly.

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

The P2B internal complaint process is accessible without legal representation, and in matters where the grounds are straightforward and the commercial exposure is limited, a well-prepared seller can handle Phase 1 through Phase 3 independently. The case for legal involvement is stronger when the commercial stakes are high – an account-level suspension with FBA inventory held and a rolling disbursement affected – when previous appeals have been rejected without explanation, when the matter involves both P2B and DSA or DMA grounds, or when mediation is being considered. The attorney-led review Tutamen offers is fixed-fee and scoped to what the matter actually requires. It is not an open commitment.
