What a Google Ads agency account is
Google does not sell a product called an 'agency account.' The phrase is industry shorthand, and it can describe two very different arrangements:
1. Your account, linked to the agency's manager account (MCC). You keep the Google Ads account you already own. The agency links it to its manager account and manages campaigns from there. Google's documentation is explicit that linking leaves the original account intact: account history remains, your users keep their existing access, and invoicing and payment methods do not change unless consolidated billing is deliberately set up.
2. An account the agency creates for you. Agencies can create new Google Ads accounts directly from their manager account. When they do, the manager account automatically becomes the account's owner — which is why ownership questions matter so much in agency-created structures.
In both cases, campaigns live in an individual Google Ads account. The manager account is a separate Google Ads account that sits above it. Google describes it as an umbrella account with several individual Google Ads accounts linked to it — not an upgrade of your existing account. One individual account can be directly managed by up to five manager accounts, but only one manager can hold ownership at a time.
So when an agency says it will 'run your Google Ads account,' the practical question is which structure they mean. Who owns the account, who is financially responsible to Google, and what you can take with you when you leave all flow from that single choice.
Agency ad account vs manager account (MCC): the difference that confuses everyone
The confusion is understandable: both objects are technically 'Google Ads accounts.'
The manager account (MCC) is the agency's control layer. Google defines it as a Google Ads account that lets you view and manage multiple Google Ads accounts — including other manager accounts — from a single location. It is where the agency links client accounts, manages users, and attaches payments profiles for invoicing. Google's own business pages pitch manager accounts as a way to manage multiple ad accounts and campaigns in one place, with reporting, access control, and consolidated billing. A manager account is required for any Ads account using monthly invoicing.
The ad account is where your campaigns, keywords, conversion data, and history actually live. It can sit under the agency's MCC or stand on its own.
Three distinctions prevent most disputes:
- Linking is not ownership. Google warns that linking a manager account doesn't automatically grant administrative ownership. If the agency linked your existing account, it manages campaigns but does not own the account unless ownership is turned on from your side.
- Ownership is singular. A client account can only have one owner. Google moved to this single-owner model in 2020; before that, an account could have multiple owner managers. If the agency created the account, it became owner automatically.
- Access is tiered. Manager account users hold one of five access levels — Administrative, Standard, Read only, Email only, or Billing. A Billing-level user can view and edit billing information without touching campaigns; an Administrative user on an owner manager can invite and remove users, transfer ownership, and adjust security settings.
One boundary cuts the other way too: your team never gains access to the agency's manager account or its other clients. Client account users have no visibility into the manager account their account is linked to.
Who owns billing, assets, and data in each setup
Billing follows the payments profile. Every billing setup is attached to a payments profile, and Google's guidance is blunt about what that choice means: with the payments profile, you are choosing who will be financially responsible for the Google Ads account. In a client-owned setup, that profile is usually yours. In an agency-run setup, it is often the agency's, with your account consolidated onto the agency's monthly invoice.
Some agencies operate under a contract setting called Sequential Liability. This puts two payments profiles on the account: the agency's profile as primary, and the advertiser's as secondary — the advertiser is sequentially liable for invoice payment if the agency does not pay. Ask directly whether this applies to your account, because it changes who Google ultimately pursues for unpaid spend.
Data stays with the client account. Google states that even an owner manager's privileges do not take data ownership away from the client account: the client account still owns its data and can remove ownership access by unlinking. Ownership grants the agency's admins administrative power — inviting and removing users, granting or revoking access, adjusting security settings — but not ownership of your performance history.
Access is the practical ownership question. If the agency created the account, its admins control who holds access. If your team only holds Standard or Read only access, you can work in campaigns but cannot perform the administrative actions that matter during a dispute or a departure. Google notes that users who have lost all administrative access may need to contact an existing administrator or submit an account access request to regain control — a position no advertiser wants to be in.
How spend and credit work in agency-run accounts
When an agency holds the payments profile, spend is typically paid through monthly invoicing, which Google describes as receiving a line of credit from Google and paying costs down according to agreed-to terms and conditions. This is why agency-run accounts can spend before money changes hands — and why Google's credit relationship sits with the payments profile holder, which in agency-run structures is usually the agency.
With consolidated billing, the agency receives one monthly invoice covering many client accounts. Google's requirements:
- A manager account is required, and all accounts on one invoice must be linked to one common manager account, known as the paying manager.
- All accounts sharing an invoice must use the same currency.
- A single consolidated invoice can cover up to 50,000 Google Ads accounts.
Each invoice shows the amount spent for each Google Ads account, the purchase order number, and a total amount due, and Google provides a monthly cost report showing activity for each account. Two caveats are worth knowing: consolidated billing is not available to media agencies and is no longer provided to advertisers in France under Loi Sapin; and budgets are set through the billing setup — during an onboarding transfer, the receiving agency sets the budget amount, budget dates, and the service agreement that governs the account.
The practical consequence: when the agency holds the payments profile, your spend capacity depends on the agency's terms with Google and the budget the agency sets on your account — rather than on a billing relationship you control directly.

What happens on exit depends entirely on which structure you were in.
If the account is yours and the agency only managed it: users with administrative access can terminate the relationship at any time by unlinking the account from the manager account. Unlinking removes the agency's access; your billing setup, history, and data stay where they were.
If the agency paid the invoices: billing has to move before the relationship is fully severed. That is the Change Who Pays process — Google defines a billing transfer as moving the billing ownership of a Google Ads account from one payments profile to another. Moving to a new agency outside the current hierarchy is an external billing transfer, and the current paying manager — the agency you are leaving — must initiate the request. Google introduced a self-serve version of this process in 2024 so agencies no longer need to contact support to start it. The receiving side has 7 days to approve or deny the request, or it is automatically canceled. Google Support reviews the submission and, if no issues arise, processes the transfer on its stated 48-hour handling timeline — though support can reject it and ask for resubmission, and the feature is in beta with some steps still requiring support assistance. Invitation emails (Account Transfer Agreement, Budget Agreement, or Service Agreement) must be accepted to finalize the move, and the account must be linked to the new manager within 7 days of the transfer or ads stop running.
If the agency created and owns the account: you have less leverage. Client account users cannot transfer ownership themselves — though they can unlink an owner manager if they hold administrative access. If you never had administrative access in the first place, regaining control may require an account access request. This is why the ownership question belongs at the start of the relationship, not the end.
Questions to ask before letting an agency run your spend
Get written answers to these before signing:
- Who creates the ad account? If the agency creates it under their MCC, they become the owner automatically. If ownership matters to you, create the account yourself and let the agency link it — linking does not grant ownership by default.
- Who is the paying manager? Ask to see the Billing Settings page. The paying manager controls the invoicing setup; if it is the agency, your billing lives inside their hierarchy.
- Whose payments profile is attached to the billing setup? That profile determines who is financially responsible for the account. If it is the agency's, ask whether Sequential Liability applies and what you are liable for if they do not pay.
- What access level does our team get? Administrative access to your own account is the difference between owning your data and requesting it. Standard or Read only access will not let you manage users or unlink a manager.
- Is our account on a consolidated invoice? If so, require the monthly cost report showing activity for your account so you can verify what you are billed.
- What is the exit process? A professional agency will describe the Change Who Pays transfer, who initiates it, the 7-day approval window, and the agreements that must be accepted. An agency that cannot describe the exit has not planned for it.
- Do we keep administrative access for the life of the account? If the answer is no, ask why — and treat it as a signal.
None of this is adversarial. Agencies with clean structures answer these questions in minutes.
