Within a Meta ad account, roles are assigned specific permissions to control access and capabilities. Only the 'Admin' role has the highest level of access, which includes managing all administrative and financial settings. This explicitly grants them the ability to add, remove, or edit payment methods and view billing details. The other roles are designed for campaign management and analysis and are intentionally restricted from accessing these sensitive financial functions to maintain account security and control.

A. Analyst: This role has view-only permissions for ad performance and reports; they cannot make any changes to the account, especially financial ones.

B. Editor: While Editors can create, edit, and manage ad campaigns, their permissions do not extend to administrative tasks like managing payment methods.

D. Advertiser: Similar to an Editor, an Advertiser can create and manage ads but is not permitted to access or modify billing and payment information.

1. Meta Business Help Center, "About roles and permissions for your Meta ad account." This document outlines the capabilities of each role. Under the "Ad account roles" section, it specifies that an Admin "Can manage all aspects of campaigns, including creating reports, viewing and editing billing details and assigning account roles."

2. Meta Business Help Center, "Add people to your ad account." In the table detailing permissions, the row for "Manage ad account payment methods and edit billing info" has a checkmark only for the Admin role, explicitly confirming this is an admin-only permission. The Advertiser and Analyst roles are shown without this capability.
