Is it worth setting up a SAS company in Colombia?

A SAS (Sociedad por Acciones Simplificada) is the most common, flexible company type — one shareholder is fine, setup is relatively quick through a Cámara de Comercio, and it can support a work/investment visa path. Whether it makes sense depends on your goals, tax situation, and whether you need it for a visa. Talk to a local contador (accountant) and lawyer before registering.
