Editors with a COI must disclose the COI, especially if you are being paid per the Terms of Use, in which case, there is a separate (but similar) process for disclosing paid editing.

COI editors are strongly discouraged to edit affected articles directly. Instead, use the {{ Edit COI}} template to propose changes to an existing article and Articles for creation for creating a new article.

The bottom line is, COI editing is just not a good idea. COI editing can cause many problems, and there are even legal consequences for hidden advertising mimicking a content format such as a Wikipedia article. If your company tells you to make or edit a Wikipedia article about them, tell them it can't be done.
