Integrated payments and buyer protection, SubMerchant

Payments run on SubMerchant, the same platform that powers every checkout on every store here. One integration, every currency, every method, every region's fraud rules. Sellers get paid out, buyers stay protected, and you can plug SubMerchant into your own product if you want to skip us entirely.

Built in. Works on day one

  • Every checkout on every store runs on SubMerchant. No wiring, no plugins.
  • Buyer protection, fraud checks, refund routing. All under the hood.
  • Sellers don't think about PCI, gateways, or chargeback paperwork.

Every payment method, every currency

  • Cards, wallets, local methods (Mada, iDEAL, PIX, Klarna, Apple Pay, Google Pay, and more).
  • Settle in your base currency. Buyers pay in theirs.
  • Add a method per market. We handle the routing.

SubMerchant is also a standalone service

  • Use the API to add payments to your own site, app, or backend.
  • Hosted checkout for drop-in use. Embedded checkout for native surfaces.
  • Same fraud engine, same buyer protection, same payout flow, outside our platform.
  • Pay-as-you-grow pricing. No platform lock-in.

Add your own payment system

  • Sellers can override the default and plug in their own gateway.
  • SubMerchant stays the secure layer underneath. Your gateway sits on top.
  • Useful for stores with existing processor relationships or unique rails.

Fraud and security

  • Per-transaction risk scoring, device fingerprinting, velocity checks.
  • Auto-block, manual review, or 3DS challenge. Your rules.
  • Chargebacks handled inside the dashboard, with evidence attached to the order.

Buyer protection

  • Buyers see trust signals at checkout. Verified seller, money-back guarantee.
  • Disputes route through SubMerchant, not the seller's inbox.
  • Resolutions land in the seller's CRM, with the full context attached.

Payouts

  • Single payout per market, on a schedule you set.
  • Balance, pending, settled. Visible at every step.
  • Holdback rules for new sellers and high-risk categories.

Built for developers

  • REST API for charges, refunds, payouts, disputes.
  • Webhooks for every event: payment.succeeded, payment.failed, chargeback.created, payout.settled.
  • Idempotent keys, versioned endpoints, sandbox environment.

We are building this right now.
