Who owns the Google Ads account, and what to settle before you cancel

The short answer: ownership is what you can operate without the agency

Who owns a Google Ads account is not written in the contract but in user management. The contract governs what you can demand. The technical setup governs what works on the morning after you cancel. That is why I consider one question telling: could you cut the agency off from the account today without its help, and would measurement, delivery and payment keep running afterwards?

Often the honest answer is "partly". That is rarely down to bad intent. Agencies set up accounts in the way that is convenient for their work: create the account in their own manager account (MCC), manage conversions centrally, pay through their own billing. Each of these decisions is reasonable on its own. Together they make switching expensive.

Disclosure: I sell freelance Google Ads management myself. What is written here applies to me just as much as to any agency.

Ownership and admin access are two different things

A Google Ads account has users with access levels and, alongside them, at most one owner manager account. According to Google, a client account can only have one owner, and a manager that creates an account from its manager account automatically becomes its owner. So if the agency created your account for you, ownership lies with the agency. If your existing account was linked to its MCC later, by default ownership does not lie with the agency. Technically, the manager account initiates a link and the client account accepts it.

The difference has consequences. Admins of the owner manager account can invite and remove users in the client account and grant and revoke admin rights. Ownership also passes upwards: if the agency's MCC sits under a further manager account, for example a holding company or a network, that account is an owner as well.

According to Google, the client account keeps ownership of its data and can remove the link. To do that, however, you need admin access to the client account. If you only have standard or read-only access, you cannot disconnect the agency yourself. According to Google's overview of access levels, only an admin can give access, change access levels, manage product links and unlink manager accounts.

The checklist in the order in which things break when you separate

Work through the points from top to bottom. The order follows what fails first when you disconnect, not what sounds most important.

Payments profile: whoever pays determines how fast you can switch

If you pay yourself by card or bank transfer through your own payments profile, this point is usually not critical. Still check who the primary contact is. Users of the payments profile cannot be changed directly in Google Ads; that only works through support, requested by the primary contact or someone with the same company domain. If an agency address is listed there, you depend on the agency for every change.

Agency billing is more delicate: the agency pays through its payment manager account and recharges you. According to Google, monthly invoicing and credit lines require ownership access for the manager account in any case. When you switch, an admin in the current paying manager account has to initiate the transfer, which means the old agency. The new agency then has seven days to accept the request, otherwise it lapses. Expect this step to be the slowest part of the whole handover if the old agency does not cooperate.

Conversion actions in the agency MCC: the silent break

This point is missing from many handover checklists and can do the most damage. Many agencies use cross-account conversion tracking: the actions sit in the manager account and apply to all clients underneath it. According to Google, client accounts can see them but not change them, and an account uses either account-specific or cross-account conversions, never both.

When you cut the agency off, its actions are gone. Your bid strategies, however, learn on exactly these actions. Target ROAS or Maximise conversion value then work without a signal, or with old account-specific actions that have not been maintained for months. The old statistics are kept, but current conversions only flow if working actions are ready in your own account.

Running both in parallel is therefore not possible. Before you cancel, prepare your own actions, with tags pointing to your account's conversion ID or an import in your own account, and set the switchover date while the agency is still cooperating. Afterwards, compare the first few days with your shop backend or GA4 and expect a short learning phase for bidding. What a clean foundation looks like is covered in conversion tracking in an online shop.

Merchant Center: verification is tied to a person

In Merchant Center, only admins manage people. Website verification is the critical part: if it is associated with a person who is removed, the verification and claim are lost, and another person has to complete both again. Check which user your domain is verified through and, if necessary, verify it again through your own admin before anyone from the agency is removed.

Tag Manager and GA4: Google itself recommends managing them in-house

For Tag Manager, Google recommends at least two active administrators and that the account is managed by someone in your organisation rather than an external agency. For GA4, check the same principle: the admin role at account level sits with you, not just at property level with the agency.

What the contract does and does not do

Clauses on handing over the account, campaigns and data make sense, but they do not replace the technical check. A contract gives you a claim that you have to enforce in a dispute. The checklist above ensures you never need it. Whether campaign structures or ad copy are protected by copyright is a legal question. A lawyer answers that, not this article.

I advise writing the technical setup into the contract rather than the other way round: account in the retailer's name, admin with the retailer, payments profile with the retailer, conversion actions in the client account. You can check all of that on day one. How to grant access correctly from the start is described in granting Google Ads access to external partners safely.

When the rule applies less strictly

Not every dependency is a problem. Agency billing can make sense for retailers who do not want to front ad spend. Cross-account conversions save maintenance if you run several accounts yourself and the manager account belongs to you. And if you are not planning to switch anyway, you do not have to rebuild everything at once. I see a genuine exception in the pay-per-lead model, in which the agency pays Google and runs its own landing pages and its own tracking. There, consultant Sam Frost also considers it more appropriate for the agency to own the account, because it builds and funds the whole system. In that case you are buying leads, not an advertising account.

I draw the line where a point can only be resolved with the agency's cooperation. As long as the relationship is going well, moving things over costs almost nothing. Once you have cancelled, you negotiate every step from a weaker position. Every point that sits with the agency can cost days of measurement or delivery during the switch. How the switch itself works without a drop in performance is covered in switching agency without a performance drop.
