Mexico’s main payment methods are cards with instalments, SPEI transfers, OXXO cash, and wallets. A checkout built only for cards will reach a fraction of the market, because a large share of Mexican consumers either have no bank account or prefer to pay in cash even when buying online.
That combination, a fast-growing e-commerce market layered on top of low banking penetration, makes Mexico one of the markets where local payment methods matter most. Mexican e-commerce was worth around USD 43 billion in 2024 and is projected to pass USD 60 billion by 2027, with roughly 67 million digital buyers growing toward 77 million. Reaching those buyers depends on offering the methods they actually use.
The Mexican payments market at a glance
Two structural facts shape everything about paying in Mexico.
The first is limited banking access. World Bank data shows account ownership in Mexico sits well below the level of comparable Latin American economies, and card penetration follows: reported figures put debit card usage near 36% of adults and credit card usage around 11% in 2024. Strict credit checks and high interest rates keep credit card issuance low.
The second is the persistence of cash. A large informal economy means many consumers are paid in cash weekly or daily, and that money often never enters a bank account. Cash is declining as a share of commerce, but it has not disappeared, and Mexico’s payment rails have adapted by building bridges between cash and digital commerce rather than waiting for cash to go away.
The result is a market where cards, instant bank transfers, and cash vouchers all carry meaningful e-commerce volume at the same time. Gr4vy’s guide to payment methods by country sets Mexico alongside other markets with similar dynamics.
Cards and interest-free instalments (meses sin intereses)
Cards remain the most common e-commerce payment method in Mexico among the banked population, with Visa, Mastercard, and American Express all present alongside domestic schemes such as Carnet. Debit is used more heavily than credit, reflecting both wider debit access and a consumer preference for avoiding revolving credit on everyday purchases.
The detail that catches out international merchants is meses sin intereses, interest-free monthly instalments. In Mexico, offering interest-free instalments on higher-value purchases is close to an expectation rather than a perk, and its absence at checkout visibly suppresses conversion on larger baskets. Merchants selling electronics, appliances, furniture, or travel into Mexico without an instalment option are competing against local sellers who offer it as standard. Gr4vy’s guide to how instalment payments work covers the mechanics.
A related consideration is local acquiring. Domestic acquiring in Mexico generally produces higher approval rates than routing Mexican cards through a foreign acquirer, and it avoids cross-border fees. Gr4vy’s guide to acquiring for international markets covers the tradeoff.
SPEI bank transfers
SPEI is Mexico’s interbank instant payment system, operated by Banco de México. It settles transfers between bank accounts in seconds, at low or no cost to the consumer, and it has become a mainstream way to pay for higher-value purchases online. Adoption is now broad: SPEI processes billions of transactions annually and reaches a substantial majority of banked Mexicans.
For merchants, SPEI is attractive on cost and finality. Transfers are cheaper than card interchange and, being push payments, they carry no chargeback exposure. The tradeoff is user experience: a SPEI payment usually involves the customer leaving checkout to complete a transfer in their banking app, which introduces friction and abandonment risk compared with a card entry.
SPEI is best deployed as an option alongside cards rather than as a replacement, particularly for higher-value baskets where the cost saving is material and the customer is willing to take an extra step.
OXXO cash vouchers
OXXO is the mechanism that connects cash to online commerce in Mexico, and it has no real equivalent in most markets. At checkout, the customer selects OXXO, receives a voucher with a reference number, and then pays in cash at any OXXO convenience store. The store network runs to more than 20,000 locations nationwide. Payment is confirmed to the merchant quickly, which lets the order proceed.
OXXO Pay accounts for around half of all cash-based voucher transactions in Mexican digital commerce, which makes it the single most important way to reach consumers who have no card or bank account, or who simply prefer cash.
Two practical points for merchants. First, OXXO payments carry no chargeback risk, since the customer pays cash against a voucher. Second, they are not instant: the customer has to physically visit a store, so there is a delay between order and payment, and a proportion of vouchers expire unpaid. Merchants need order-handling logic for the gap between voucher issued and cash received, and should not treat an OXXO selection as a completed sale.
Digital wallets and A2A methods
Wallet adoption is growing quickly from a low base, with the Mexican digital wallet market projected to expand several times over by 2030. Mercado Pago is the most significant wallet in the market, carrying both its marketplace user base and standalone acceptance.
Banco de México has also pushed two account-to-account initiatives worth understanding, because their trajectories differ sharply. CoDi, launched in 2019 for QR-code payments over SPEI, saw slow uptake, reaching only around 1.9 million users and under USD 1 billion in transactions across four years. DiMo, launched in 2023 for transfers using a phone number, performed far better, surpassing 7 million users in its first year with backing from major banks. Banxico projects that account-to-account transfers via DiMo could grow from around 6% to 8% of online transactions by 2027.
The honest read is that neither has displaced cards or SPEI, and DiMo is the one worth watching rather than building for immediately.
How to accept payments in Mexico
A workable Mexican payment mix for an international merchant is straightforward in principle: cards with interest-free instalments for the banked majority, SPEI for higher-value and cost-sensitive transactions, and OXXO to reach cash-preferring and unbanked customers. Wallets sit alongside these as the growth layer.
The complication is that each of those methods comes through different providers, with its own integration, settlement behaviour, and reconciliation. OXXO vouchers behave nothing like card authorizations, SPEI is a push payment with no chargeback path, and instalments require specific handling with the acquirer. Adding them one by one, as separate engineering projects, is what usually delays market entry.
This is where a coordinating layer helps. Connecting to multiple providers through one integration and controlling which methods appear for Mexican customers turns market entry into a configuration exercise, which is the problem payment orchestration addresses. Gr4vy supports SPEI and OXXO through several connectors, alongside cards and Mercado Pago, so a Mexican payment mix can be assembled without separate builds for each method.

Frequently asked questions
What are the most popular payment methods in Mexico?
Credit and debit cards are the most used online payment method among banked consumers, usually with interest-free instalments on higher-value purchases. SPEI bank transfers are widely used for larger transactions, OXXO cash vouchers serve cash-preferring and unbanked shoppers, and digital wallets such as Mercado Pago are growing. Most merchants selling into Mexico need cards, SPEI, and OXXO at minimum.
What is OXXO Pay and how does it work?
OXXO Pay lets a customer buy online and pay in cash. At checkout the customer selects OXXO and receives a voucher with a reference number, then pays at any of the more than 20,000 OXXO convenience stores in Mexico. The merchant is notified once payment is made. It accounts for roughly half of cash-based voucher transactions in Mexican digital commerce and carries no chargeback risk, though payment is not instant and some vouchers expire unpaid.
What is SPEI?
SPEI is Mexico’s interbank instant payment system, operated by Banco de México. It moves funds between bank accounts in seconds at low cost and is widely used for higher-value online purchases. For merchants it is cheaper than cards and carries no chargeback exposure, but it typically requires the customer to complete the transfer in their banking app, which adds friction compared with card entry.
Do I need to offer instalments to sell in Mexico?
For higher-value purchases, effectively yes. Interest-free monthly instalments, known locally as meses sin intereses, are a standard expectation on larger baskets in Mexico, and their absence noticeably reduces conversion on categories such as electronics, appliances, furniture, and travel. Local competitors generally offer them, so an international merchant without instalments is at a disadvantage.
Can I sell in Mexico with cards only?
You can, but you will reach a limited share of the market. Card penetration in Mexico is comparatively low, with debit usage around 36% of adults and credit around 11% as of 2024, and a large share of consumers prefer or need to pay in cash. A card-only checkout excludes the customers who rely on OXXO and misses those who prefer SPEI for larger purchases.
What is the difference between CoDi and DiMo?
Both are Banco de México initiatives for account-to-account payments. CoDi, launched in 2019, uses QR codes over SPEI and saw slow adoption, reaching roughly 1.9 million users in four years. DiMo, launched in 2023, uses phone numbers to send transfers and grew much faster, passing 7 million users in its first year with major bank support. Banxico projects DiMo could lift A2A to around 8% of online transactions by 2027.
Is local acquiring important in Mexico?
Yes, for approval rates and cost. Routing Mexican cards through a domestic acquirer generally produces higher authorization rates than processing them cross-border, and avoids cross-border fees. For merchants with meaningful Mexican volume, local acquiring is usually one of the higher-impact changes available.
How big is e-commerce in Mexico?
Mexican e-commerce was worth around USD 43 billion in 2024 and is projected to exceed USD 60 billion by 2027, with the number of digital buyers growing from roughly 67 million toward 77 million. Growth rates have run well above the global average, which is part of why the market attracts international merchants despite its payment complexity.
Getting the Mexican payment mix right
Mexico rewards merchants who take local payment behaviour seriously and penalises those who assume a card-first checkout will travel. The market has real scale and fast growth, but the buyers are split across three quite different payment behaviours: banked card users who expect instalments, bank-transfer users paying through SPEI, and cash users reaching digital commerce through OXXO. Serving only one of those groups leaves most of the market unaddressed.
The practical approach is to cover all three from the start, then let the data show where volume concentrates by category and basket size. Merchants that treat OXXO as an afterthought usually find it carries more volume than expected, and those that skip instalments usually see it in their higher-value conversion rates.
