The automotive aftermarket is becoming more digital, and we are helping lead that shift through a strategic partnership with Mercado Livre, the leading e-commerce platform in Latin America. By integrating our TecDoc data standard into their system, we are making it faster and easier for sellers to publish parts listings and scale their online business.
Auto parts are now the third-largest category on Mercado Livre, following consumer electronics and home and industrial goods. The company currently manages between 85 and 90% of digital auto parts transactions in the region. However, onboarding remains a challenge for many sellers due to the time and complexity involved in building accurate online catalogs.
Reaching every buyer, everywhere
Before the integration, listing a single part could take up to 43 minutes. Sellers had to manually write descriptions, upload images, and assign vehicle applications. Now, when a product already exists in TecDoc, the seller can add their stock and pricing, check the information, and publish the listing in about 3 minutes.
This process is made possible by TecDoc’s standardised and structured vehicle and product data. Standardisation removes inconsistencies and prevents duplicate entries, making it easier to manage listings and reducing the risk of fitment errors.
As Heloísa Monzani, Managing Director Brazil and Regional Sales Director South America at TecAlliance, explained: “With TecDoc it is online. When manufacturers add the information, it is automatically connected, and all customers, including Mercado Livre, can access it.”
Scaling reach through standardised data
Mercado Livre serves more than 35 million unique auto parts buyers across Latin America every year, including 20 million in Brazil alone. Around 35% of purchases are made by professional buyers such as mechanics, who shop much more frequently than consumers and rely on precise compatibility information.
According to Stefânia Pokladek, Head of Commercial Strategy LATAM Auto Parts at Mercado Livre: “When the catalog is more accurate, it’s more interesting. That means there are fewer complaints, fewer returns, and better acceptance. With correct applications, conversion improves by about 40%.
Latin America also presents unique data challenges. Unlike Europe or the United States, many countries in the region do not have standardised vehicle registration information. In Mexico, for example, documents can vary by region, and “chocolate cars” – used vehicles imported informally – are part of the active fleet. TecAlliance actively maps and maintains these vehicles in its database to ensure coverage is as complete and accurate as possible.
“What is behind it, the strategy behind this alliance, is our expertise, our database – which TecAlliance builds for vehicles and replacement parts in a standardized way, in a single language – and making that information available in Mercado Livre’s system to make life easier for sellers, so they can sell in a simpler, more accurate way and avoid rework,” highlighted Pokladek.
By combining structured data with marketplace scale, our collaboration is helping transform how auto parts are sold across Latin America. From Mexico to Argentina, the partnership brings faster onboarding, more accurate listings, and broader market access to sellers of all sizes.
