WordPress basically resolves the basic-most problem for most of the potential business persons who don't have any technical background, yet want to raise a website.
I have had witnessed the fact that a non-technical person has raised an average functioning website using WordPress within 3 hours. I mean, imagine having a technical expert or a dedicated WordPress developer by your side, developing a website on WordPress for your business could not only produce a fully-functional website but could also add some dynamism like scroll up and down, and interactive transition effects, etc. using additional WordPress Plugins.
Make sure to ask your hired developer or a software development company about all the customized themes. Also, we should also keep our eyes on not just ours but the development platform's competitors like WooCommerce, Drupal, Magento, etc.
Why WordPress is better than the others is the must to know fact, because when 'Why' is clear, the 'How' becomes easier.
