TL;DR
- A manager account is a separate, new Google Ads account; it cannot hold campaigns itself, and its time zone and currency cannot be changed after setup.
- One email address can be associated with up to 20 Google Ads accounts, manager accounts included, which is the point where Google recommends a manager account.
- A client account can have only one owning manager, keeps ownership of its own data, and its users can always unlink the owner.
- Unlinking keeps campaign history but stops the manager's shared remarketing lists and cross-account conversion tag, and halts ads if that manager was the paying manager on monthly invoicing.
A Google Ads manager account (often called an MCC, from its old name "My Client Center") is a separate Google Ads account that lets you see and manage many other Google Ads accounts from one sign-in. It does not run ads itself; campaigns always live in the linked client accounts, and the manager account sits above them for access, reporting, billing and shared tracking.
That last point causes most of the confusion. Agencies use manager accounts to run client work, and business owners often only find out about them when they try to change agencies and discover they cannot see their own account. This guide covers how a manager account works, how to set one up and link accounts, how access levels and ownership decide who controls what, and what happens on the day an agency relationship ends.
What a Google Ads manager account actually is
Google describes the manager account as an umbrella account with individual Google Ads accounts linked underneath it. It is a new account, not an upgrade of an existing advertiser account, so you cannot turn the account that already runs your campaigns into a manager account.
From a manager account you can:
- sign in once and move between every linked account, including other manager accounts;
- create and edit campaigns inside the client accounts;
- compare performance and run reports across accounts;
- link a payments profile for monthly invoicing and consolidated billing;
- set alerts on linked accounts;
- give users different access levels;
- hold ownership of client accounts so it can manage their user access.
Manager accounts can also be nested. A large organization might have one top-level manager, a manager per region underneath it, and the advertiser accounts at the bottom. Reporting and access then follow that tree.
There is one practical limit worth knowing before you start. A single email address can be associated with up to 20 Google Ads accounts, and manager accounts count toward that number. Once you look after more than a handful of accounts, signing in to each one separately becomes unworkable, and that is the point where Google itself recommends a manager account.
How to create a manager account
The steps in Google Ads Help are:
- Go to the Google Ads manager accounts page and choose to create a manager account.
- Sign in with the email address you want to use for it. Use an address your business controls, not a personal inbox that leaves with an employee.
- Enter an account name. Clients will see this name in their client account, so use your real business name. URLs are not accepted.
- Choose how you will use the account: to manage your own Google Ads accounts, or to manage other people's.
- Select your country and time zone.
- Select a currency.
- Finish setup and open the account.
Two of those choices are permanent. The time zone cannot be changed later because Google uses it for reporting and billing, and the currency is also fixed. Client accounts keep billing in their own currencies; the manager account only lets you view costs converted into its currency. If you work across Thailand and other markets, pick the currency you want to read your roll-up reports in.
Once a manager account exists, you can create further manager accounts underneath it from the sub-account settings, which is how the nested structure above is built.
How to link client accounts
There are two ways to get an advertiser account under a manager account.
Create a new client account from the manager
Open the Accounts icon, go to Sub-account settings, select the plus button and choose Create new account. Follow the prompts. A manager that creates an account becomes its owner automatically, which matters later (see the ownership section below).
Link an existing account by invitation
For an account that already exists, open Sub-account settings, select the plus button and choose Link existing account. Enter the 10-digit customer ID of each account, one per line if you are linking several, preview the request and send it.
The link is not active until the client side accepts. Users with administrative access to the invited account receive an email. They can accept from that email, or in Google Ads under Admin, then Access and security, then the Managers tab, where pending link requests appear. Once accepted, the account shows up in the manager account. The sender can withdraw a request that has not been answered yet from the Sent Link Requests list.
Linking an existing account does not give the manager ownership. That is a separate setting the client account has to enable.
Manager link vs giving someone direct user access
There are two separate ways to let someone into your Google Ads account, and they behave differently.
Direct user access means you invite a person's email address to your account as a user, at an access level you choose. That person signs in and sees only your account. Removing them is a single action in Access and security.
A manager link connects your account to an agency's manager account. Everyone the agency has given access to inside its manager account can then reach your account through it. You do not see those people as individual users of your account, and you cannot invite your own staff into the agency's manager account. Google states that client account users cannot be given access to the manager account or to other accounts linked to it.
For a business owner, the safe pattern is to use both: keep at least one person from your own company as an Admin user directly on the account, and let the agency work through its manager link. The direct Admin is your way back in if the relationship ends badly.
Access levels, explained
Google Ads has five access levels.
| Access level | What it can do | What it cannot do |
|---|---|---|
| Admin | Everything below, plus manage users and access levels, accept or unlink manager accounts, add or remove product links, edit payments profile and payment methods, complete advertiser verification | No restrictions listed by Google |
| Standard | Edit campaigns, run reports, edit billing information, create conversions from Google Analytics events | Manage user access, accept or unlink manager links, add or remove product links, edit the payments profile |
| Read only | View campaigns, users and managers, run performance and billing reports, grant email-only access | Edit campaigns or any billing details |
| Email only | Receive notification emails and reports | View campaigns, billing or users |
| Billing | View and edit billing information, make payments, manage the payments profile | View or edit campaigns, see users, receive notifications |
Most agencies only need Standard access to do the day-to-day work of building and optimizing campaigns. The jobs that require Admin are about control of the account itself: who can get in, which managers are linked, and how it is paid for.
Who owns the account: ownership in a manager account
Ownership is a status a single manager account can hold over a client account. A client account can have only one owner. Admin users of the owning manager can invite and remove the client account's Admin users, grant or remove admin access, accept or decline link requests, unlink other managers, enable remarketing list sharing, change security settings, and transfer or turn off ownership.
Two facts from Google Ads Help matter more than the list of powers:
- The client account still owns its data. Ownership by a manager does not take data rights or admin rights away from the client account.
- Client account users cannot transfer ownership, but they can always unlink the owning manager. After that, they can enable ownership for a different manager.
So "who owns the account" in the business sense comes down to whose payment method is on it, which company's people hold direct Admin access, and whether the account was created under the agency's manager (making the agency the owner by default) or created by the business and linked in later. If an agency created your account, ask for direct Admin access for someone at your company on day one, not when you are about to leave.
Consolidated billing
Consolidated billing puts the costs of many accounts onto one monthly invoice. It has strict requirements:
- a manager account, linked to a payments profile;
- every account on the invoice linked to the same manager account, which Google calls the paying manager;
- monthly invoicing as the payment setting, which is a line of credit Google extends to businesses that meet its eligibility requirements, so not every advertiser can use it;
- a shared currency across the accounts on one invoice. Mixed currencies produce one consolidated invoice per currency.
Google also states the feature is not offered to media agencies.
Cross-account conversion tracking
Normally each Google Ads account has its own conversion actions and its own tag. With cross-account conversion tracking, you create the conversion actions in the manager account and choose which client accounts use them. One tag then records conversions for every account that uses those manager-level actions.
The rules that trip people up:
- An account uses either its own conversion actions or the manager's cross-account actions, not both. The switch is the Conversion account setting.
- If an account is linked to more than one manager, it can use conversion actions from only one of them.
- Client accounts can see cross-account conversion actions but cannot change them. Only the manager account can.
- Google Analytics conversions must be imported into the manager account that owns the cross-account actions.
This is convenient when one website serves several accounts, for example separate accounts per brand or per country pointing at the same checkout. The trade-off is dependency: your conversion data now runs through someone else's manager account.
What happens when you leave an agency
Ending a manager link is called unlinking. Someone with administrative access to either side, the manager account or the client account, can do it. Before you unlink, check what the manager account was doing for you, because several things stop at once:
- The account keeps its own campaign history and all Google Ads features. Your campaigns, ads, keywords and past data stay where they are.
- The manager account, and everyone who reached you through it, loses access.
- Remarketing lists that depend on the manager's shared tag stop filling. Ad groups that target those lists, and campaigns that exclude them, stop running.
- If you used the manager's cross-account conversion tracking, its tag stops recording conversions for new clicks. Clicks from before the unlink can still convert within their conversion window. If the account had its own conversion tag before, that tag resumes tracking.
- If the account is on monthly invoicing and the manager being unlinked is the paying manager, the account stops serving ads. The new billing setup has to be created under the manager the account will move to, before you unlink.
A clean handover therefore looks like this: confirm someone at your company has direct Admin access, rebuild any remarketing lists and conversion actions inside your own account (or under the new agency's manager), sort out billing if you are on monthly invoicing, link the new manager, and only then unlink the old one. Google also requires that a client account keeps at least one user with access, or a link to an owning manager, before a manager can drop it.
Can you use a manager account for one business?
Yes. The setup screen asks whether you will manage your own accounts or other people's, and "your own" is a supported choice. A business with one Google Ads account gains little from it. A business with several accounts gains a lot: separate accounts per brand, per country or per currency, a single login for staff, roll-up reports, and the option of a shared conversion setup.
It also changes the agency conversation. If you hold your own manager account with your accounts under it, you can link that manager to an agency's manager instead of handing over each advertiser account, and you stay the owner of the structure.
What this means for businesses in Thailand
The permanent currency and time zone choices matter more than they look. A Thai business that later expands into other markets may end up with accounts in THB and in another currency; reporting can be converted to the manager's currency, but consolidated invoices, where available, are split by currency. Choosing the Bangkok time zone keeps the manager's reporting days aligned with local business hours.
Agency changes are the other common situation. Before signing with any agency, ask three questions in writing: whose manager account will the ad account sit under, who will be the owner, and will your company keep a direct Admin user. Those answers decide how easy it is to leave later.
Frequently asked questions
Can one Google Ads account be linked to more than one manager account?
Yes, an account can be linked to more than one manager, but only one of them can be its owner. It can also use cross-account conversion actions from only one of those managers.
Can I run ads directly from a manager account?
No, a manager account cannot hold campaigns of its own. You create campaigns inside a client account, which you can do while signed in to the manager.
Will I lose my data if I unlink my agency's manager account?
No, your account keeps its campaign history and data after unlinking. What stops are the shared items that belonged to the manager: its remarketing lists, its cross-account conversion actions, and billing if the manager was your paying manager on monthly invoicing.
What access level should I give my agency?
Standard access covers campaign work, reporting and conversions from Google Analytics events. Keep Admin with someone at your own company so you control users, manager links and payment details.
How many accounts can one email address manage without an MCC?
One email address can be associated with up to 20 Google Ads accounts, manager accounts included. Past that point, a manager account is the practical way to reach every account from one login.
