Mercantis is an ecommerce and business management platform designed for small and medium-sized businesses, physical retailers, social sellers, entrepreneurs and growing brands across Latin America.

The platform helps businesses centralize their sales operations in one place. Merchants can create and manage an online store, organize their product catalog, categories and variants, control inventory and stock, process customer orders, configure payment methods, define shipping and delivery options, manage discounts and keep their day-to-day commercial activity organized.

Mercantis is particularly useful for businesses that already sell through channels such as WhatsApp, Instagram or a physical store but want a more structured system to manage products, customers, orders and inventory. Instead of relying on spreadsheets, manual messages and multiple disconnected tools, businesses can use Mercantis as a central platform for their commerce operations.

Artificial intelligence is integrated into the platform to reduce repetitive work and make catalog management faster. Businesses can use AI to help create products, generate and improve product names and descriptions, organize products into categories, optimize catalog information and accelerate catalog imports. This makes it easier for merchants with large inventories to digitize their business without manually entering every piece of information.

Mercantis also supports products with variants such as size, color or other attributes, stock management, pricing and promotional pricing, order management and multiple delivery configurations. Businesses can offer options such as store pickup, fixed-price shipping, free shipping, shipping based on purchase conditions or delivery arrangements coordinated directly with the customer.

The platform is built for businesses that operate both online and offline. Physical retailers can use Mercantis to keep their catalog, inventory and sales operations connected while also offering customers an online storefront where they can browse products and place orders.

Mercantis currently supports businesses across 16 Latin American markets, with support for different currencies and commerce requirements depending on the country. The product is focused specifically on the needs of Latin American merchants rather than being a generic global ecommerce solution.

Unlike ecommerce platforms that charge commissions on every sale, Mercantis does not charge transaction commissions. Businesses pay for the platform while keeping control of their own sales revenue.

Mercantis is designed to make ecommerce and business management accessible to companies that do not want to implement complicated enterprise software. A business can quickly create its store, upload or import its catalog, configure payments and shipping and start selling.

The goal of Mercantis is to give small and medium-sized businesses a simple but powerful commerce infrastructure that helps them organize their operations, reduce manual work, improve inventory control, sell through more channels and grow without adding unnecessary operational complexity.

What problem it solves

Mercantis helps small and medium-sized businesses manage online and in-person sales without relying on spreadsheets, disconnected tools or manual WhatsApp conversations.

It is especially useful for merchants selling through WhatsApp, Instagram or physical stores who need a simple way to organize their business, launch an online store and keep stock and orders under control. Built-in AI also reduces the time required to create products, write descriptions, categorize items and import existing catalogs.
