Seller Agreement

1. Status, Self-Classification, Duty to Update

(1) Before the first Listing the Seller selects one of three statuses:

• Private — occasional sale of own collection items without profit intent.
• Small business (Kleinunternehmer § 19 UStG) — VAT-registered entrepreneur applying the small-business rule (no VAT statement on invoices).
• Commercial — VAT-registered entrepreneur; § 25a UStG margin scheme may apply per item.

(2) The Seller keeps this classification current; on transition (e.g. Private → Commercial), the profile must be updated without delay.

(3) Platform reclassification right. Where a Seller classified as Private appears commercial by volume, regularity, marketing, or conduct, We may require evidence, pause Listings, and reclassify the Seller. Indicators include sales frequency, large amounts of similar goods, planned purchase for resale, professional appearance, parallel sales channels.

(4) DAC7 note. The DAC7 de-minimis threshold (fewer than 30 goods transactions and less than EUR 2,000 consideration in the reporting period) is nota commercial threshold; it only governs the Platform's tax reporting obligation.

2. Seller Profile — Mandatory Fields

• Full name (natural person) or company including legal form;
• Service-of-process address; for commercial Sellers also publicly visible on the Seller profile;
• Email; optional phone;
• For commercial Sellers: VAT ID (USt-IdNr.) or tax number as substitute;
• On presentation of a § 22f UStG certificate: issue date, issuing office, validity;
• State of tax residence (mandatory for DAC7);
• Date of birth (natural person) or commercial register data (entity), insofar as required for DAC7/PStTG reporting;
• Bank details or accepted payment channels (shown to Buyer);
• Confirmation that only own or sale-authorised goods are offered (§ 4).

These fields are kept current; address, VAT ID, or banking changes must be reflected in the profile without delay.

3. Listing Duties

(1) Every Listing contains truthful information on:

• Item title, release year, artist, label, catalogue number where applicable;
• Condition per Goldmine industry-standard grading (Mint … Poor) for media and sleeve;
• Photographs (front, back, vinyl surface where defects are visible — minimum three photos on first listing);
• Total price; commercial and small-business Sellers include any applicable VAT;
• Shipping costs and delivery regions;
• Delivery time;
• For commercial and small-business Sellers: provider identification, withdrawal policy (Platform template or compliant own text), where applicable § 25a UStG margin-scheme notice.

(2) The Seller may use the Platform's withdrawal template where applicable, or substitute a compliant own text.

(3) Private sale disclaimer.For Sellers classified as Private, the Listing automatically displays: "Private sale. Consumer rights for purchases from traders do not apply; in particular there is no statutory right of withdrawal. The Seller may exclude liability for defects."

(4) The Seller is solely responsible for the accuracy of the condition description. Age-typical wear is not a defect where described.

4. Ownership, Authenticity, Prohibited Goods

(1) The Seller warrants ownership or authority to sell, and absence of conflicting third-party rights.

(2) The Seller warrants in particular that the goods are

• not stolen or unlawfully obtained;
• not counterfeit or unlawfully reproduced and do not infringe trade-mark, copyright, or other rights;
• not harmful to minors, violent, discriminatory, or otherwise unlawful;
• not subject to export or sanction restrictions.

(3) Breach is an important reason for sanction under § 9.

5. Communication, Shipping, Order Handling

(1) The Seller responds to Buyer messages within 48 business hours; on auction win, payment instructions are also delivered within this window.

(2) For third-party goods, the Seller initiates shipping within 3 business days of payment receipt unless a longer time is stated on the Listing. Tracking is entered through the Platform's tracking function where available.

(3) For off-platform payment (Path B / order_intent) the Seller confirms receipt of payment in the Platform; only then does the Buyer's shipping address become visible and the Listing is marked sold.

(4) Buyer data is used only for fulfilment of the contract; purpose-foreign use — in particular direct marketing — is prohibited.

6. § 22f UStG, § 25e UStG, DAC7 / PStTG Data Handling

(1) The Seller acknowledges that the Platform must collect, store, and where applicable transmit certain Seller and transaction data to tax authorities on the basis of statutory obligations. Legal basis is the relevant statutory obligation (Art. 6(1)(c) GDPR), not consent.

(2) The Seller authorises processing for this purpose, including transmission to the Federal Central Tax Office (BZSt) and other competent tax authorities under DAC7 (PStTG) and § 22f UStG record-keeping. Retention periods follow statutory rules (generally ten years).

(3) Where mandatory data are not provided or validated, the Platform may deactivate Listings or suspend the Seller until the data are supplied.

(4) § 22f UStG certificate. Where issued, the Seller uploads the certificate (USt-1-TJ) to the profile and updates it on expiry.

7. Liability and Indemnification

(1) The Seller is liable to Buyers under statutory rules for performance of the purchase contract, in particular delivery, absence of defects, authenticity, withdrawal (in B2C contracts), and statutory information duties.

(2) The Seller indemnifies the Platform against any third-party claim arising from a breach of this Agreement, the Platform Terms, or applicable law (in particular consumer rights, trade-mark rights, tax obligations, DAC7 reporting). This includes reasonable legal-defence costs.

(3) Platform liability toward the Seller is governed by § 12 of the Platform Terms.

8. Membership, Quota, Listing Suspension

(2) Listing quota is consumed per § 5(6) of the Platform Terms; on Membership end, Listings are suspended per § 5(7) of the Platform Terms.

(3) A payout block as sanction is not foreseen because no money flow runs through the Platform. Alternative sanctions follow § 9.

9. Sanctions, Suspension, Termination

(1) On breach of this Agreement, the Platform Terms, or law, the Platform may — depending on severity and repetition — take the following measures:

• warning;
• removal of the Listing;
• temporary listing suspend;
• temporary or permanent Seller account suspension;
• termination of the Seller Membership for cause.

(2) The Seller will be heard before a permanent measure unless the protective purpose conflicts.

(3) Important reasons include proven counterfeits, stolen goods, repeated false statements, misuse of Buyer data, circumvention of DAC7 / § 22f obligations, serious breach of § 4.

10. Term and Ordinary Termination

(1) This Agreement runs indefinitely, coupled to the Seller's underlying Membership.

(2) Either party may terminate ordinarily on 14 days' notice to month-end. Sellers terminate electronically from the member area.
