Mexico is Latin America's second-largest e-commerce market, but a large share of adults still lack a bank account and card penetration remains only moderate, so paying for online purchases in cash remains a deeply rooted habit. With more than 20,000 stores nationwide, the OXXO network is the leading channel connecting that cash demand to online orders, capturing exactly the customers that a card-only store would otherwise miss.

OXXO is worth prioritizing for mid-ticket B2C stores in categories like fashion and household goods, open-marketplace sellers with a high share of first-time buyers, and digital content sellers targeting younger customers who find card limits restrictive. Because cash payment involves a delay before receipt confirmation, though, you'll need to design your inventory-holding policy and automatic cancellation window for unpaid orders alongside it.

When a consumer selects OXXO at checkout, a reference number with a barcode is issued online, and the consumer pays in cash at a nearby OXXO store before it expires. Payment is typically confirmed the next business day, and the merchant confirms the order once Hecto Financial relays the receipt confirmation. Since this isn't an instant-approval method, managing the status of each stage — issuance, payment, and confirmation — is central to the integration.

Through Hecto Financial, a business in Korea can explore OXXO cash payment as one of its online payment methods without a local entity in Mexico or a separate collection agreement. Operational conditions such as reference number validity periods and how unpaid orders are canceled vary by industry and transaction volume, so these should be confirmed with the sales team before contracting.

• Country of business registration

  Confirm whether contracting is possible for businesses registered in Korea

• Sales channels

  The integration method and priority differ depending on your mix of online sales channels — direct-to-consumer site, open marketplace, mobile app, and so on

• Product categories

  Check in advance whether your products fall under restricted categories per OXXO's merchant policy

• Local regulatory compliance

  Confirm compliance with Mexico's payment and foreign exchange regulations (see official sources below)

Cash paid by consumers at OXXO stores is received in Mexican pesos (MXN), then converted and settled in whichever of USD, KRW, or JPY the merchant selected under the contract. The settlement cycle follows the contract terms. Since cash payment, unlike a card, cannot be reversed as an original-transaction cancellation, refunds are handled through a separate transfer, and it's safer to confirm the process and turnaround time at the contracting stage.
