In regards to performing maintenance, we highly suggest having backups (which we’ll help you make), and a staging area (which we can help with on specific hosts, such as SiteGround or WP Engine).
In regards to billing, we bill each site that we maintain together in a multisite if you have a professional plan or higher. We don’t support multisite on personal plans, as they can get complex and large, and each site could stand alone in many cases.
Contact us if you’d like to setup a custom plan. We’re flexible!
