Many website headaches begin with unclear ownership. Your domain is the address people type. Hosting is where the website runs. The website files and database are the site itself. Business email may be hosted by a completely different provider.
Keep access organized
Know who owns the registrar account, hosting account, DNS, email service, analytics, and site administrator accounts. Use named users where possible, enable multi-factor authentication, and keep renewal notices going to an address the business controls.
Ask what a proposal includes
Clarify whether hosting is included, who handles renewals, how backups work, and what happens if you change providers. A professional should be able to explain the arrangement without making access dependent on one person.
These details are part of a responsible website handover, not an afterthought.
