Let your marketplace account be protected like your most valuable asset.
Seller-account compliance on Amazon, eBay, Etsy, and local marketplaces: the KYBC verification file, listing rules, account-suspension appeals, and P2B/DSA rights.
The account = the business
For an e-commerce company selling cross-border, the marketplace account is the sum of the storefront, the payment-collection infrastructure, and the customer portfolio. A suspended account halts the business overnight, whatever its revenue. This risk is manageable: demonstrable compliance with platform rules, an up-to-date verification file, and an appeal protocol that operates the moment a suspension hits.
The three layers of compliance
Verification (KYBC)
The DSA imposed on marketplaces the obligation to verify seller identity; the consistency of your trade-registry, tax, bank, and address documents is the lifeblood of the account — in events such as a trade-name change, an update reflex is essential.
Listing compliance
product-safety declarations, trademark and copyright, prohibited-product policies; infringement allegations often arrive via a competitor's complaint.
The Türkiye layer
for your domestic sales, the ETBİS, İYS and intermediary-agreement rules of Law No. 6563 (Turkish E-Commerce Law) run in parallel.
What do we do at the moment of suspension?
First we decode the real meaning of the reason code (is it performance, verification, or an infringement allegation), then we work the platform's internal appeal channel with evidence and an action plan. EU rules impose on platforms the obligation to give reasons and offer an appeal channel; if the internal channel is blocked, certified dispute resolution and court options come into play. In parallel, a temporary plan for stock, shipping, and cash flow is set up — an appeal can take weeks. The whole process is the core practice of our International E-Commerce Focus Area.
The EU rule set as a whole
Marketplace compliance cannot be reduced to a single instrument. The DSA establishes seller verification and the statement-of-reasons regime; the P2B Regulation (2019/1150) requires advance notice of changes to terms, transparency in ranking and an internal complaint-handling system; and under DAC7 platforms report seller income to the tax authorities — so your platform data and your tax filings can now be cross-checked against each other. On the product side, the GPSR affects your account directly, through mandatory listing information and the requirement for a responsible person established in the EU. Each of these layers calls for its own documentation; if the file is not held together in one place, an appeal against suspension is delayed.
Who is it for, and what do you get?
Typical users: Turkish sellers operating across several EU markets, brands running their own website alongside a marketplace, and acquisitions that involve the transfer of an account.
What you get: an index to the verification file, a country-by-country obligations matrix, a DAC7-to-filing reconciliation checklist and an annual scan for rule changes. The contractual groundwork on the website side is completed by the distance-selling set.
A rehearsal is part of the set-up: in the annual exercise the suspension scenario is played through from start to finish, and the gaps in the appeal file are closed before a real incident.
We are by your side for Marketplace & Platform Compliance
We begin with an account-health audit: the verification file, listing risks and past warnings. Then an appeal protocol (who, with which document, within what time) and the brand-protection link (anti-counterfeiting) are established. On Amazon's European marketplaces, our Germany Desk handles the German-language processes.

You have the right to a counter-notice; it is pursued with your evidence of rights ownership and your sales history. In bad-faith complaints, damages and sanctions at platform level come into play.
The core file is common (identity, tax, trademark); short annexes are kept for platform-specific rules (packaging, returns, performance metrics). This structure keeps updates sustainable.
Save the notice stating the reason and do not send a panicked appeal. Diagnosing the root cause and appealing with a single, complete action plan is far more effective than a string of weak appeals —…
In the EU, the DSA and P2B rules impose on platforms an obligation to state reasons and to provide an appeal route. Where a restriction comes without reasons, these rights are asserted in writing and, where necessary, taken to formal channels.

Let us identify the right solution together, drawing on our experience in Türkiye and the DACH region.
