How to implement adding a WordPress "company"?

Question

CMS

That is, it is necessary for users to add their company in their personal account only 1 time to display it on the site.
I understand that this is a blog structure in any case, but in addition to such a "blog", the site will also have a blog that will be used for its intended purpose.
That is, there is also a problem in the " multi- blogging " on the site.
Maybe someone faced a similar problem?
I will illustrate:

Answer 1

It's unclear. Where to add a company? Is it just a company name? Where should it be displayed? Should any data be filtered / sorted by it?
What is a "blog structure" and what is "multi-blogging", how are they related in this context, and what is the actual problem?
Write in more detail, especially your goals, what you want to get at the end.

Answer 2

Make it possible for a registered user to add your post (Company). Use wp_insert_post, then let the author of the post (company) make changes. But without knowledge of PHP, you can't do it for sure.
