Merchant Services Agreement

This Merchant Services Agreement ("Agreement") is entered into between the approved seller ("Merchant") and Nexa Merchant Services (Nexa Merchants, LLC) ("Nexa Merchant Services"). It governs payment acceptance, settlement, chargebacks, and merchant compliance for sales made through Nexa AI Marketplace.

Nexa Merchant Services provides the merchant account and payment rails. Nexa AI Marketplace provides the storefront, catalog, and buyer experience. Nothing in this Agreement makes Nexa AI Marketplace the seller of record for the Merchant's transactions.

Every approved seller on Nexa AI Marketplace is boarded as an individual merchant of record. Nexa Merchant Services provisions each Merchant with their own dedicated merchant account — not a sub-account of a shared Nexa aggregator account.

Each dedicated merchant account has its own merchant identifier (MID), its own settlement bank account owned by the Merchant, its own monthly statements, its own chargeback ledger, and its own risk and underwriting profile. Funds from the Merchant's sales settle to the Merchant's bank account, not to Nexa.

Because each Merchant holds their own account, the Merchant is directly responsible to the card networks and the sponsoring bank for the activity on that account, and receives the protections and reporting that come with individual merchant status.

After creating a Nexa account (or clicking any "Open your Nexa store" call to action), sellers begin the application at the Seller Application page at /seller/apply. This form collects legal business information for admin review.

Once the application is approved, the Merchant completes onboarding at the Merchant Boarding page at /seller/boarding. Boarding collects KYC / KYB documentation, beneficial-owner information, banking details for settlement, and acknowledgement of this Agreement.

The Merchant can return to /seller/boarding at any time to check status, upload additional documents, or update banking information. Both pages are accessible from the seller dashboard navigation after sign-in.

To provision a dedicated merchant account, Nexa Merchant Services collects standard know-your-customer and know-your-business information: legal business name and structure, tax identification number (EIN or SSN), beneficial-owner information, business and mailing addresses, a valid government-issued ID for the signer, and a bank account for settlement.

Nexa Merchant Services may request additional documentation to satisfy card-network rules, sponsoring-bank requirements, and applicable BSA / AML obligations. The merchant account cannot be activated until required documentation is verified.

Standard processing fees apply to each transaction. The fee schedule in effect for the Merchant is disclosed in the merchant application flow and on the Merchant's dashboard, and may be updated with notice.

Net proceeds — gross sales less fees, refunds, chargebacks, and reserves — settle directly to the Merchant's designated bank account on the settlement schedule disclosed at boarding. Because settlement is direct-to-Merchant, Nexa Merchant Services does not custody Merchant funds beyond the standard processing window.

The Merchant is financially responsible for chargebacks, refunds, and reversals arising from their sales, including any associated fees. Elevated chargeback ratios may result in reserves, holds, additional monitoring, or termination consistent with card-network rules.

Nexa Merchant Services provides tooling to receive dispute notifications and submit representment evidence. The Merchant remains the counterparty of record to the buyer and to the card networks for each disputed transaction.

As the merchant of record for their own transactions, the Merchant is responsible for product fulfillment and shipping, customer service and communications, returns and warranty handling, and compliance with all laws applicable to their products and their business — including sales tax collection and remittance where applicable.

Nexa AI Marketplace provides the storefront, discovery, and payment rails; the Merchant owns the sale, the customer relationship, and the goods or services delivered.

The Merchant may not use their dedicated merchant account to process transactions for products or activities prohibited by the Prohibited Products Policy or the Acceptable Use Policy, by the card networks, by the sponsoring bank, or by applicable law.

Attempted transaction laundering — processing transactions on behalf of a business other than the one boarded — is grounds for immediate suspension and termination.

Nexa Merchant Services or its sponsoring bank may suspend processing, hold funds pending investigation, apply reserves, or terminate the merchant account when reasonable indicators of fraud arise, when chargeback ratios or refund velocity exceed network thresholds, upon material breach of this Agreement, upon direction from the card networks or sponsoring bank, or as required by law.

The Merchant may close their merchant account at any time by written notice. Termination does not relieve either party of obligations that arose before termination, including chargeback liability for prior transactions.

Nexa Merchant Services receives the transaction data required to process payments, run risk checks, and satisfy regulatory obligations. Handling of that data is governed by the Nexa AI Marketplace Privacy Policy and by the terms of the sponsoring bank and card networks.

Cardholder data is handled by PCI-compliant processing partners. The Merchant is not required to store cardholder data to accept payments on Nexa AI Marketplace.

Nexa Merchant Services may update this Agreement from time to time. Material changes will be communicated to the Merchant in advance through the seller dashboard or by email to the address on file.

Governing law and venue will be specified in the counsel-approved final version of this Agreement.
