In a significant update, Census has introduced a self-service billing portal allowing users to upgrade their plans without human interaction. This change enables users to manage payment information and access invoices at their convenience. The process involves three easy steps: selecting a plan, confirming and checking out, and then accessing various features such as a free trial, destination connectors, and the Segment Builder. To support customers, Census has provided helpful resources including product documentation, pricing information, and a Slack community. With this update, users can now efficiently manage their plans and take advantage of Census's features without relying on human assistance.
