Choosing the Right Marketplace: Fees, Regions, and Your Products

Pick platforms by matching them to your priorities. Consider this framework:

1. Match products to categories: MercadoLibre's 20 main and 123 smaller categories across 19 LATAM countries including Colombia work well for varied items like clothing or tech.

2. Evaluate fees: Weigh Vinted at 0% or Facebook Marketplace at 5% for used goods, Mercari at 10% for general resale, against MercadoLibre's 16-17%.

3. Consider regional operations: Colombia and LATAM sellers gain from MercadoLibre's local presence over platforms without it.

High-volume sellers in LATAM may trade MercadoLibre's fees for its category variety and biweekly payouts, while sampling lower-fee sites for targeted stock.
