Currently the service allows for monthly client billing with the option to increase the rate.
Adding the ability to hand off the responsibility for managing payment for hosting to the client would be great. I don't need to be involved in the post launch website management for all my clients.
Client billing allows you to retain control of the project and charge your client for hosting. You can learn more about how to set that up here.
If you wish to transfer ownership of the project and its hosting subscription to your client, you can transfer your project to your client once you client creates an account on Webflow. Learn more here.
