E-commerce in Brazil will generate $19.7bn in 2015 - a 17,3 percent increase on last year's figures, according to research from consulting firm eMarketer.
Within Latin America, Brazil is the best performing market, followed by Mexico with predicted sales of $5.7bn and Argentina, where the forecast is $4.96bn, according to the research.
E-commerce revenues in Latin America should reach $38.2bn in 2015 - a 23,9 percent increase on 2014 numbers.
According to the consultancy, the forecast is that the region will generate $84.7bn in online sales by 2019.
Separate research by AT Kearney suggests that Brazil is currently the ninth largest market in the world in terms of online sales, with 106 million Internet users and 60 million online consumers.
However, the AT Kearney report also points out that between 2014 and 2015 Brazil has performed poorly in the global e-commerce market: due to the current economic slowdown, the country went from 7th to 21st place in the analyst's ranking of 30 countries, based on aspects such as online commerce attractiveness and growth potential.
