Pricing
CustomCoRover uses a custom, subscription-based enterprise pricing model with no public self-serve rate card. Pricing depends on factors such as the number of users, deployment type (chatbot, voicebot, videobot, or IVR bot), selected platform modules, and whether the organization needs on-premises, cloud, or hybrid infrastructure. Both monthly and annual billing options are available, and customizations or fully custom enterprise solutions are quoted directly by CoRover's sales team after a requirements discussion. Prospective customers should contact CoRover via its website to request a demo and tailored quote.
