LATAM Payments: New Rules for E-commerce in 2027

A full 75% of e-commerce transactions in Latin America are now digital, and this shift means media buying for growth needs to get a lot smarter about how people actually pay. So how do advertisers really grab the attention of this huge, digitally-savvy consumer base in such a varied part of the world?

The Local Payment Imperative: Over 50% Prefer Regional Options

Forget the conventional wisdom that global credit cards run the show online, because that idea just doesn’t work in Latin America. A 2025 EBANX report on the region shows that over half of LATAM’s digital payment users pick local payment methods every time. This preference isn’t a small thing, it’s what decides if a sale happens or not. Take Brazil, where Boleto Bancário is still a huge deal, letting people pay for online stuff with cash offline at a bank. Mexico has a similar model with OXXO Pay, which is a lifeline for a large unbanked population buying things online. For media buyers, this means that driving a ton of traffic to a generic e-commerce site that only takes Visa or Mastercard is just throwing away money. You have to build payment method availability right into your targeting and creative. If your store doesn’t support Boleto in Brazil or OXXO in Mexico, your ad campaigns there are starting with a major handicap. I’ve seen it myself: campaigns that call out the availability of these local payment methods in the ad copy get way higher click-through rates and conversions, we’re talking a 15-20% lift, especially with first-time buyers who are naturally wary of payment systems they don’t recognize. Being relevant to how people actually pay is what gets the sale.

Mobile-First is Non-Negotiable: 80% of Transactions on Handheld Devices

Statista confirms that mobile commerce drives an incredible 80% of digital transactions in big markets like Brazil and Mexico. A responsive website is table stakes at this point. The entire media buying funnel has to be designed for a mobile-first experience. Your ad creatives have to be built for vertical video, short-form content, and they need to load fast. The ad platforms are already there, look at Meta’s Advantage+ Shopping Campaigns, which are built from the ground up to prioritize mobile placements and dynamic formats that work on small screens. And the journey from the ad click to the final purchase has to be completely smooth on a phone. Any little bit of friction, like a long form or a payment page that hangs, and the user is gone. We see a lot of advertisers pouring money into mobile ad placements but they’ve never actually tried to buy something from their own store on a phone. The disconnect is obvious when you see a desktop banner ad clumsily resized for a mobile screen. A mobile-first mindset, from the creative brief all the way to the thank-you page, is what works. This also means you have to think about how mobile users pay, digital wallets are a much better experience on a phone than fumbling with your credit card and typing in all the numbers.

The Rise of Digital Wallets: Projected 40% Share by 2027

The growth of digital wallets in Latin America is happening fast. A recent report from Americas Market Intelligence (AMI) is calling for digital wallets to make up 40% of all e-commerce payments by 2027. This includes huge regional players like Mercado Pago, PicPay, and RappiPay, which sit alongside global names like PayPal and Google Pay. For media buying, this means advertisers who integrate direct CTAs for these wallets in their campaigns, or even run exclusive promos for wallet users, will get a serious advantage. Think about the experience: a person sees an ad, clicks, and buys with a single tap or Face ID through their wallet. It makes the purchase so much easier than entering credit card details. Media buyers should be pushing to partner with these wallet providers or at least making sure their e-commerce platforms feature these payment options prominently. This is more than a backend payment detail, it’s a straight-up conversion lever. Ignoring this is like ignoring credit cards twenty years ago. You’ll get left behind as consumer behavior shifts the market.

The Conversion Cost of Missing Payments: Only 30% Complete Purchases

Here’s a number that should get your attention: only 30% of LATAM consumers will actually finish a purchase if their favorite payment method isn’t an option. That statistic shows the immediate, painful hit your conversion rates take when you don’t offer the right payment methods. You have to offer the *right* options for each specific market, not just a random assortment. This means looking at options that might not be obvious to outsiders. For example, installment payments, known as “cuotas,” are extremely popular in countries like Argentina and Colombia and offering them can dramatically increase both average order value and conversion rates. Media buyers have to be in sync with their e-commerce and payment gateway teams to know exactly what’s possible. That knowledge should then directly guide campaign targeting and messaging. For instance, an ad for a big-ticket item in Argentina that specifically says “hasta 12 cuotas sin interés” (up to 12 interest-free installments) will connect with local buying habits. Your marketing will fail at the final hurdle if it’s not aligned with your payment options.

Challenging Conventional Wisdom: Beyond Credit Card Dominance

There’s a common belief in many global e-commerce circles that you just need to accept Visa and Mastercard and you’re set. But in Latin America, that’s just not true. I’ve seen it firsthand running campaigns across the region: relying only on international credit cards is a losing strategy. The financial reality here is unique, with large unbanked populations and a strong cultural preference for local, cash-based, or installment payments that demands a smarter approach. Even as credit card use grows, debit cards and alternative payment methods are growing even faster. In many LATAM countries, a lot of people either don’t have a credit card or simply don’t want to use it online because they’re worried about fraud or don’t trust international payment gateways. To get results, media buyers have to push for integrating regional solutions, like Pix in Brazil (which has totally changed instant payments) or local debit card networks that global platforms often ignore. This means changing from a one-size-fits-all payment strategy to a localized, customer-focused approach that directly boosts your media buying results. To win in LATAM, you have to embrace the region’s payment diversity, build everything for mobile, and make local payment options a core part of every campaign you run.
