A business website is often built on whatever platform was easiest on the day. Years later, the company finds that moving away is hard, and the monthly fee has become a permanent cost. Portability avoids this.
What portable means
A portable website is one where you hold the source files and can host them with more than one provider. If prices change or service quality drops, you move. The site, its content and its search history stay with you.
Static sites are a good fit for most companies
Many company websites are mainly information: services, industries, articles and a contact form. Such a site can be built as static files. Static files load fast, have a small attack surface because there is no database or server code to break into, and can be hosted at very low cost.
The trade-off is that content changes are made in the source files and published through a build step. For a site that changes a few times a month, this is a small price for speed and security.
Questions to ask before you build
Who owns the code and the domain? Can the site be exported and hosted elsewhere? What happens to forms and email if the platform is changed? Is there a written guide for making routine updates?
Clear answers at the start save cost and trouble later.
