Every second, 566 transactions are processed within the Mercado Pago ecosystem. This pace leaves no room for error: any instability, however brief, directly impacts the revenue of companies that depend on the platform to operate.
It was in this veritable testing ground, with billions of reais in transactions per day and a user base of 78 million in Latin America, that Mercado Pago developed the infrastructure that consolidated its presence in the Large Accounts and Enterprise segments.
Throughout its history, Mercado Pago has become known for serving millions of small and medium-sized entrepreneurs, becoming a gateway to the world of digital payments. This foundation, however, is only part of the story.
The same technology has evolved to meet increasingly complex operations, expanding its scope of action. Today, Mercado Pago operates across the entire pyramid – from micro-entrepreneurs to large corporations – supported by a structure capable of handling significant transaction volumes, different channels, and continuous demands for performance.
In the Large Accounts and Enterprise segment, Mercado Pago already serves leaders in the electronics, technology, tourism, and other markets, and continues to structure itself to expand its leadership in this segment. The model also encompasses cross-border and e-commerce transactions.
These are operations that deal with peak demand, high transaction volume, and low tolerance for failure. In this context, the payment method directly influences business performance.
As the payment solution for Mercado Libre, the largest e-commerce platform in Latin America, Mercado Pago is able to analyze an extensive database of consumer data. This volume feeds models that make real-time decisions, adjusting risk parameters and reducing friction throughout the purchase journey.
“In practice, this represents a major competitive advantage,” says Beni Harari, Commercial Director of Large Accounts and Enterprises at Mercado Pago. The executive points out that small variations in the approval rate can represent millions of reais in additional revenue for large companies – and this is where the platform's technology stands out.
Another advantage is that Mercado Pago has specific models based on artificial intelligence for large accounts, such as prevention systems capable of identifying suspicious behavior without compromising legitimate transactions. This demonstrates the level of personalization and assertiveness. The result is a rare balance in the sector: increased conversion with rigorous risk control.
“We put all the knowledge that Mercado Libre provides us to work for our clients,” says Harari. “With this, we can guarantee the same experience that someone has within Mercado Libre also within Mercado Pago.”
In addition to combating fraud, artificial intelligence is also being applied to improve customer service, combining automation and human interaction to make the payment experience even better. Specifically for Enterprise accounts, Mercado Pago offers premium service, providing a team of payment specialists dedicated to personalized support for these clients.
Not surprisingly, Mercado Pago has an NPS score of 77, one of the highest in the industry, an indicator that measures customer satisfaction. In 2025, Mercado Pago processed US$83.7 billion in total payment volume, with US$55.7 billion in acquiring alone.
Although native to the digital environment, the company has recently moved into the physical world. In addition to point-of-sale terminals, it has begun offering an EFT (Electronic Funds Transfer) solution, which integrates payments with management systems, inventory control, and invoice issuance, consolidating its movement to meet the needs of large accounts.
With this model, a company can use online checkout and, at the same time, connect its physical stores to the same infrastructure, centralizing data and simplifying processes.
At the heart of the strategy, Harari emphasizes, is omnichannel. Mercado Pago has integrated digital and in-person payments into a single environment, allowing companies to operate seamlessly between channels and transform scattered data into business intelligence.
Harari points out that this architecture relies on a broad portfolio of payment methods – which includes cards, Pix, QR Code, bank slips, payment links, digital wallets and EFT – offering alternatives for different operations.
Furthermore, Mercado Pago also has a Cross Border Payments model, allowing companies without a legal entity in Latin America to sell and receive payments in local currency from end customers in countries throughout the region, without the need to establish a company locally.
Embedded in an ecosystem that combines e-commerce, media, and financial services, Mercado Pago has also begun to operate in demand generation.
This is achieved through solutions like Mercado Ads and the presence of brands within the app itself, connecting companies to millions of active users. As a result, the platform no longer acts solely at the point of payment, but also influences the beginning of the consumer journey, directing traffic directly to the online or physical stores of Mercado Pago clients.
In sectors such as e-commerce and entertainment, where peak access times are critical, the combination of scale and technology becomes crucial. In product launches or ticket sales, for example, seconds of instability can represent significant losses – it is in this type of scenario that the robustness of the Mercado Pago platform reaffirms its value.
By expanding its reach to large companies, Mercado Pago is no longer seen merely as an entry point for small businesses, but is establishing itself as a payment solution capable of handling complex operations. "We want to be a partner in the growth of companies," concludes Harari.
