  • Paid tier (Startup, Developer, Professional, Expert) exact USD prices are not published on the public pricing page

Vizion

  • No price is published: the site names a pricing link but shows no per container rate, no plan tier and no minimum, and every route leads to a demo or a sales conversation
  • There is no self service signup, so even a small shipper must go through sales to start tracking
  • Container tracking, trade intelligence and supply chain optimisation are separate product lines rather than one subscription
