Revenue growth on marketplaces does not always translate into real profit for small and medium-sized companies. Before scaling sales on Mercado Livre, specialists recommend that entrepreneurs evaluate the business's financial structure to prevent expansion from turning into debt. Mercado Livre has established itself as the largest e-commerce platform in Latin America, attracting thousands of Brazilian SMEs that see the channel as an opportunity to expand operations without the fixed costs of a physical store.
The apparent ease of entry, however, can hide challenges that only become apparent with increased order volume. Commission fees, subsidized shipping costs, payment release timelines, and the need for working capital to replenish inventory make up an equation that, if miscalculated, compromises the financial health of the operation.
Pricing represents the first point of attention. Many sellers replicate prices used on other channels without incorporating all the specific costs of the marketplace, which can result in negative margins even with high sales volume. Additionally, the payment collection timeline for sales on Mercado Livre can create gaps in cash flow that require adequate working capital planning.
