Contracts and ownership

Who should own the Meta ad account: the company, not the supplier

September 2026 · Contracts and ownership · Quebec City

The ad account should be opened in your company's name, and the supplier should work in it as a guest. That is my position, and I argue it from mechanics, never from the platform's authority. Meta requires nothing here. Its documentation describes several working arrangements, including one where the marketing partner owns the ad accounts. What it does document is that owning an asset and accessing one are two different positions, and that only one of them carries the right to hand out access.

This is written for the owner of an industrial SME about to hand campaigns to a supplier, or already working with one and never having thought to ask. The wider framework sits on the Facebook and Meta advertising page. This page covers one question only: whose name the account is in, and what that changes the day the relationship ends.

Owning is not accessing

Meta's developer documentation describes two ways a business reaches an advertising asset. It owns the asset, or it accesses it as an agency. The word agency there means a type of business entity that can manage or access assets owned by another business. That is not sales vocabulary. It is the platform's data model.

The consequence is written plainly in the business-to-business documentation:

You cannot grant access to assets of which you are just an AGENCY.Meta, Business-to-Business Functions, developer documentation, fetched 23 September 2026

Translated into your world: whoever owns the account decides who comes in and who goes out. Whoever only accesses it as an agency can do the work, but cannot pass that access to a third party. The same documentation notes that one business may request access to an ad account or a Page owned by another. Request. If your supplier holds the owner position, your company is the one asking and your supplier is the one granting or refusing. That is not paperwork. It is the order in which the two companies can act on each other.

What Meta writes to marketing companies

Meta's page on ad accounts speaks directly to suppliers, and it is short:

Most marketing companies won't need to claim ad accounts from their clients.Meta, Ad Accounts, business asset management, developer documentation, fetched 23 September 2026

The next sentence points those same companies to the procedure for requesting access to assets owned by another business. In the platform's own documentation, the ordinary case is to request access, not to claim ownership.

A second model is documented, the one where a partner acts on behalf of its client. Meta writes there that the client continues to be the owner of their business, and that the client can revoke the partner's system user or remove access to certain assets. The supplier works without friction, the client keeps the controls. That is the arrangement I argue for.

I owe you the other half. Meta's best practices page also describes, without disapproval, an arrangement where the marketing partner owns the ad accounts and the customer owns only its Pages. Meta neither requires nor recommends anything on this point. The word should, in the first sentence of this page, is mine. It stands on what the alternative costs the client, not on a platform rule that does not exist.

The structure where the client has no access, and it is legitimate

Meta documents a two-tier structure. A parent business creates a child business on behalf of its client, keeps complete access to it, pays for the child's ad activity and bills its clients separately. It is documented, it is sanctioned by the platform, and serious suppliers use it. It also contains one sentence every buyer should read before signing:

By default, the client does not have access to the Child Business Manager.Meta, 2-Tier Business Manager Solution, developer documentation, fetched 23 September 2026

By default. The documentation adds that the parent business may choose to give permission to the client based on their use case. May choose. A Beauce manufacturer spending every month inside that structure has not necessarily made a mistake. It does need to know which structure it is in, and to have known at signature rather than at the moment it changes supplier.

LinkedIn describes the same idea in other words

LinkedIn documents five roles on an ad account: Billing admin, Account manager, Campaign manager, Creative manager and Viewer. Its documentation on managing accounts for a business says a user can claim ad accounts the business owns or request access to a partner's ad accounts. The same split as Meta, in different vocabulary: owned on one side, shared on the other.

LinkedIn adds a mechanic that traps people a different way:

Ad accounts must have a billing admin. To remove a billing admin, you'll need to add another billing admin first.LinkedIn, Remove a User from an Ad Account, LinkedIn Marketing Solutions help, fetched 23 September 2026

The person who creates the account is automatically assigned as the billing admin, per the same documentation. If your supplier opened the account, your supplier holds that seat, and it cannot be vacated without naming a replacement first. LinkedIn also states that you must be an account manager to remove another user. Two platforms, two vocabularies, one question: who holds the position that carries the last word.

The four questions to ask, and the answer that should end the conversation

These belong before the signature, not at the notice period. They fit in one email.

  1. Whose company name is the ad account opened under. The good answer names yours, in one sentence, with no detour.
  2. Who pays the platform. If ad spend runs through the supplier's card and comes back to you as a rebill, you need to know why and to see it in writing. Meta documents that arrangement. It is not illegitimate. It is simply different from what many owners think they are buying.
  3. Can I remove your access myself. In the model where the client stays the owner, Meta's documentation says the client can revoke the partner's access. Ask whether that is your case. An answer that starts with "we would have to handle that for you" is already an answer.
  4. What stays with me the day we stop. Ad account, Pages, pixel, audiences, one asset at a time, in writing. Meta's documentation lists the pixel among the same business assets as the ad account, owned or shared. What then happens to each asset when an access is removed is documented nowhere public, and I am not going to invent it to scare you. That is precisely why it belongs in the contract.

The answer that should end the conversation is one line: it is simpler if we open it on our side. It is indeed simpler, for the supplier. The same instinct applies to audiences. Meta documents that a partnership relationship must first be established between the two businesses, and that audiences can only be shared in one direction. None of this negotiates well over the phone six months later.

On the Signal programme, it is settled in advance: the client owns the ad accounts. There are two of us, I run the accounts myself, and nothing is relayed through an account manager. I would rather a company be able to leave with what it paid for. Ownership is also one of the questions to put to any supplier in how to choose a B2B marketing agency, and it decides the value of everything described in Meta pixel conversion events.

One thing I will not cover: who legally owns an ad account. That is a contract question, and it is not mine to answer. Have the clause drafted by your own counsel. What this page gives you is what to ask that counsel to cover.

When this does not apply

Two situations where this page should not alarm anyone.

The first: your company has never advertised and has no account at all. You are not in danger, you are in the strongest position available. Nothing was built under the wrong name and there is no history to defend. The only thing to do is put the four questions to the first supplier, before anything is opened.

The second: your current supplier already set it up properly. The account is in your company's name, you see your invoices, you have your own access. There is nothing to tear down to prove a point, and a machining subcontractor in Levis does not need to reopen a file that works. If you are unsure, the question fits in one sentence by email, with no drama.

There is also an honest limit to what you can demand. A supplier does not owe you access to its own internal assets, its other clients' accounts, or its tools. What must carry your name is what your budget paid for.
