ChatGPT Ads for Agencies: How to Manage Multiple Client Accounts

Yes, you can manage multiple clients’ ChatGPT Ads accounts using the same OpenAI login, but as of September 17, 2026, OpenAI does not currently have a Meta Business Manager / Google Ads MCC-style agency hierarchy where you create an agency manager and formally nest client ad accounts beneath it.

The recommended agency setup is:

1. Each client creates their own advertiser account using their legal business details at OpenAI Ads Manager. OpenAI specifically says agencies creating advertiser accounts on behalf of clients isn't currently supported.
2. The client completes business verification, billing, country, currency and payment setup under their own company.
3. The client invites your agency email—for example, your ads@agency.com account—to their advertiser account.
4. They can give you Admin, Member, or Viewer access. Admin can manage the account and users; Member can manage campaigns; Viewer is read-only.
5. You then use the same OpenAI ads login to access multiple client advertiser accounts and switch between them. OpenAI explicitly supports one login belonging to multiple advertiser accounts.

So structurally, think of it this way:

Meta

Agency Business Manager → Client Business → Ad Accounts

Google

Agency MCC → Client Google Ads Accounts

ChatGPT Ads today

Your agency login → invited separately into Client A / Client B / Client C ad accounts

There is currently no agency-level MCC dashboard sitting above all those client accounts in the same mature sense as Google Ads Manager Accounts.

One important limitation: once your login belongs to 10 or more ad accounts, you can't self-create another advertiser account yourself. However, clients can continue inviting your login to additional existing ad accounts, so this does not prevent an agency from managing more than 10 clients.

For your agency, I would structure access like this:

This keeps billing, verification, advertiser identity and ownership with the client, while Nikitha handles campaigns and optimization. That's much safer than creating all client accounts under your agency's business details.

Also relevant for you: India currently has self-service ChatGPT Ads Manager access, so Indian businesses can create their own accounts directly.

For larger agency arrangements, OpenAI also mentions agency/technology partners and direct Ads sales support, but the standard self-service product currently uses the individual-ad-account invitation model.
