In fact, there exists just one case where using WordPress is deemed a good business decision: if it meets the software requirement specification of a given web project.

Generally speaking, WordPress is usually the no.1 choice if the project falls under the category of content-based portals such as blogs/newspapers.

When making a decision on the use of WordPress, security vulnerabilities of the WordPress core and plugin should be considered. At the same time, most of the themes and plug-ins as well as the core of WordPress are not fully compatible with PHP 7. Moving WordPress website from PHP 5 to PHP 7 can as such break the website.

There are limits of customization that come with any system built with WordPress CMS. If the WordPress-based project grows (more registered users, more operations per second, etc.), at some point there is no choice but to re-create it with a framework (such as Laravel) or (if it is possible) to migrate the website to the Laravel framework.
