This is normal. Because they wanted to make the price right for everyone/every situation, Webflow pricing ended up to be a little bit complex.
You need a Site Plan for each website you want to host with a custom domain. You don’t even need an Account Plan if you pay for the Site Plans, for the sites to be full featured.
CMS: need a Site plan each. As soon as the Site Plan is paid for, you can add Collaborators roles for the CMS. Account Plan has nothing to do with this either here.
Can you rephrase this question please?
Client Billing possible on every site with a Site Plan.
Digital, you have the choice of who’s emiting the invoice: it’s either your name and address on the invoice, or Webflow’s. This choice depends on your local laws. If you’re in France, as Webflow collects the money, then set the invoice to show Webflow’s name and address.
So what is Account Plan for then?
Account Plan gives you the possibility to have an unlimited number of sites in development or just hosted on .webflow.io domain (unlimited for Pro, 10 for Lite). It also gives you the ability to transfer sites to another account. Also unbranded stagings (stagings are sites on .io domain). Also Account Plan gives you the ability to export the code of any of your projects. Also white labeling and site’s password.
