The study aims to explain the omnichannel characteristics and behaviors of micro, small and medium-sized enterprises (MSMEs) in the food sector in Antioquia, Colombia. It evaluates the conditions necessary to achieve an omnichannel classification based on three dimensions: marketing models, multichannel options, and supply chain with digital technologies. An explanatory methodology using empirical data from surveys of 140 MSMEs was applied, and cluster analysis was used to group the companies. The results show relatively low overall omnichannel behavior, with medium enterprises outperforming small and micro enterprises. Enhanced digital technologies and integrated platforms can significantly improve omnichannel conditions, leading to better profitability and customer retention. The findings emphasize the importance of digital integration and the need for further research into the technological and methodological aspects of omnichannel implementation.The study aims to explain the omnichannel characteristics and behaviors of micro, small and medium-sized enterprises (MSMEs) in the food sector in Antioquia, Colombia.

Avalia as condições para alcançar a classificação omnichannel em três dimensões: modelos de marketing, opções multicanal e cadeia de suprimentos com tecnologias digitais. A metodologia explicativa utilizou dados de pesquisas aplicadas a 140 MPMEs e análise de cluster para agrupar as empresas. Os resultados mostram um comportamento omnicanal geral relativamente baixo, com as médias empresas superando as pequenas e microempresas. Tecnologias digitais aprimoradas e plataformas integradas podem melhorar significativamente as condições omnicanal, levando a uma melhor lucratividade e retenção de clientes. Os achados enfatizam a importância da integração digital e a necessidade de mais pesquisas sobre os aspectos tecnológicos e metodológicos da implementação omnicanal.
