You must disclose your COI in at least one place, but the safest approach is all three: on your User page using templates like {{Paid}} or writing your own disclosure statement, on the Talk page of articles you're connected to using {{Connected contributor (paid)}}, and in edit summaries when making suggestions. Your disclosure should clearly state your connection to the organization, acknowledge you understand Wikipedia's COI policies, and confirm you'll follow proper procedures like using Talk pages instead of direct editing.
