Google Ads Manager Account: How to Manage Multiple Accounts

A Google Ads manager account is the tool Google built for anyone who runs more than a handful of Google Ads accounts: one sign-in, one place to link client accounts, control who sees what and pull reports across all of them. Agencies still call it an MCC, but the setup choices you make in the first week decide whether it stays tidy at 50 accounts or turns into a permissions maze.

This guide is the Google counterpart of our Meta Business Manager setup guide (Meta now calls Business Manager a business portfolio). The logic is similar, but Google's model of linking, ownership and billing has its own rules, and every fact below comes from Google Ads Help pages we checked.

What a manager account is

Google describes a manager account as an "umbrella" account with individual Google Ads accounts linked underneath it. According to Google's overview of manager accounts, it lets you:

• Sign in once to reach every linked account, including other manager accounts
• Create and manage campaigns for client accounts from one dashboard
• Compare performance and run reports across several accounts at once
• Monitor all linked accounts with alerts
• Create new Google Ads accounts or link existing ones
• Link to a payments profile for monthly invoicing

Two details matter early. First, a manager account is a new account, not an upgrade of your existing one. Second, Google allows up to 20 Google Ads accounts, manager accounts included, per email address, and recommends a manager account once you handle more than that.

Step 1: Create the manager account

Google's creation guide walks you through a short form:

1. Go to the manager account homepage and select Go to Manager Accounts.
2. Sign in with the email you want to own the manager account. Use a shared business address, not one person's inbox.
3. Enter an account name. Clients see this name in their own account, so use your agency's trading name. Google no longer accepts URLs in account names.
4. Choose the primary use: managing your own accounts or managing other people's accounts.
5. Pick country and time zone. Google states that time zones cannot be changed, and the time zone affects reporting and billing.
6. Pick a currency. It is permanent for the manager account, while client accounts keep billing in their own currencies.

Treat time zone and currency as fixed decisions. If you report to clients in several regions, set the manager account to the zone your finance team closes the month in.

Step 2: Link client accounts

You have two routes: create new accounts from the manager account (they link automatically), or link accounts that already exist. For existing accounts, Google's linking steps are:

1. In the manager account, open the Accounts icon, then Sub-account settings.
2. Select the plus button and Link existing account.
3. Enter the customer ID, one per line if you are linking several.
4. Preview, then Send request.

The request goes by email to people with administrative access to the invited account. The client accepts under Admin > Access and security > Managers, or straight from the invitation email. You can withdraw pending requests from Sent Link Requests, which helps, because Google's linking errors page caps a manager account at 20 pending invitations.

What linking does and doesn't change

According to Google's linking overview, linking leaves the client account as it was. Its existing users keep their sign-in and permissions, and billing access is unchanged. The manager account also does not become an administrative owner by default: the client has to turn that on.

That distinction is the heart of agency access in Google Ads. Without ownership, your team can run campaigns. With ownership, your admins can also manage the client's administrative users and transfer or remove ownership. Ask for ownership only when you genuinely need it, and explain why in the onboarding email.

Step 3: Set user access levels

People access client accounts through the manager account, so their access level there matters more than any setting inside a single client account. Google lists five levels:

What an administrative user can do on a client account also depends on ownership. Google notes that without it, admins are limited to actions such as inviting standard, read only or email only users. Some tasks, like reactivating an account or unlinking another manager, may need ownership or a direct sign-in with administrator credentials.

Least privilege in practice: most of your team should be Standard. Keep Administrative to two or three named people (never one: if that person leaves or loses their Google account, you lose hierarchy control). For a broader role design that covers every platform you run, see our guide to setting up agency team roles across ad accounts.

Step 4: Decide on consolidated billing

Consolidated billing puts many Google Ads accounts on one monthly invoice instead of one invoice each. Google lists the requirements:

• A manager account acting as the single paying manager for every account on the invoice
• The monthly invoicing payment setting, which is a line of credit repaid on agreed terms
• One currency per invoice (mixed currencies produce one consolidated invoice per currency)
• Up to 50,000 accounts per invoice

Google also notes two exclusions: media agencies can't use consolidated billing, and it is no longer offered to advertisers in France. Many agencies skip it entirely and leave each client paying on their own card or invoice, which keeps ad spend off the agency's balance sheet. Decide this with your finance lead before you onboard the first client, because moving accounts between payers later is a formal billing transfer that needs approval.

Step 5: Use the cross-account features

Linking is only half the value. These features are where a manager account saves real hours.

Account labels

Account labels are created in the manager account and assigned to client or sub-manager accounts. Only manager accounts can see them, so clients never notice your internal tags. Use them for team owner, vertical, contract tier or "at risk" status, then filter the accounts list by label.

Shared negative keyword lists

From the manager account's Shared library you can create negative keyword lists for client accounts. They appear in each client's Shared library by default, but nothing changes until the client account applies the list to campaigns. Any later edit to the list flows to every campaign that uses it, so a single update can protect many accounts, and a single mistake can hurt them all.

Cross-account conversion tracking

Cross-account conversion tracking lets several accounts share conversion actions created in the manager account, with one Google tag. Google's rules to know:

• An account uses either account-specific or cross-account conversions, not both
• Client accounts can see cross-account actions but only the manager account can edit them
• Switching methods can change which goals campaigns bid towards, so check campaign goals afterwards
• Keep the old tag running until the conversion window has passed

This suits a brand that splits activity across several accounts on the same website. It rarely suits separate agency clients.

Cross-account bid strategies

Cross-account bid strategies are Smart Bidding portfolio strategies created at manager level and stored in the manager account's Shared library. Google supports Target CPA, Target ROAS, Maximise conversions, Maximise conversion value, Maximise clicks and Target impression share for Search, and Target ROAS for Shopping. Each portfolio can only hold campaigns in one currency. Watch the unlinking side effect: if an account leaves the manager account, its campaigns get an invalid bid strategy and stop showing ads until someone picks a new strategy.

If you want rule-based guardrails rather than bidding portfolios, our Google Ads automated rules guide covers what native rules can change and where they stop.

Step 6: Plan the hierarchy and limits

Manager accounts can link to other manager accounts, so large agencies often build sub-managers per team, region or client group. The limits from Google's account limits page and linking pages:

Google also limits hierarchy depth, and an account can be linked only once within the same hierarchy. Its help pages disagree on the exact depth (the linking overview says six levels, the linking errors page says five manager levels), so keep your structure shallow: two or three levels is plenty for almost every agency.

Step 7: Lock down security

Google's security mandates for manager accounts let admin users set a minimum baseline for the manager account and every account it owns:

• Require 2-Step Verification or Advanced Protection for users signing in, with an effective date you choose
• Restrict allowed email domains, so only addresses on your company domain (and your client's) can be invited

Sub-accounts can be stricter than the mandate, but not weaker. Set both on day one. Personal Gmail addresses on a client account are the most common way former freelancers keep access long after they should have lost it. Google's 2-Step Verification page explains the options for the second step, from an authenticator app to a security key.

When a client leaves

Offboarding is where ownership decisions come back to you. Google's unlinking guide gives two paths:

• From the agency side: Accounts icon, Sub-account settings, tick the accounts, Edit, Unlink, review the preview and confirm.
• From the client side: Admin, Access and security, Managers tab, Remove access, then confirm.

Either way you need administrative access. Google's errors page adds a rule that catches agencies out: every account must keep either a user with administrative access or a manager account with administrative ownership. If you created the account from your manager account and nobody at the client has admin access, invite their admin first, then unlink. Remember the bid strategy side effect above, and move any campaigns off cross-account portfolios before the handover.

Common mistakes

Creating the manager account with a personal email. The address becomes a single point of failure. Use a shared business mailbox and at least two administrators.

Asking for ownership by default. Clients are right to be wary. Request it when you have a concrete reason, and offer to release it at the end of the contract.

Making everyone an admin. Standard access covers day-to-day campaign work. Admin rights should be rare and named.

Applying shared lists without a review step. One bad negative keyword in a shared list can block traffic across every campaign that uses it.

Mixing up account labels and campaign labels. Account labels sit in the manager account and are invisible to clients. Campaign labels sit inside each client account, where the client can see them.

Forgetting the rest of the media plan. A manager account only sees Google Ads. If your clients also spend on Meta, TikTok or Snapchat, you still have several dashboards to reconcile. Our framework for managing ads across multiple platforms shows how to bring them together.

Beyond Google: one view for every platform

The manager account solves access and reporting inside Google. Most agencies run Meta business portfolios, TikTok Business Centres and more alongside it, each with its own permission model. That is the gap Wevion fills.

Wevion connects six platforms (Google, Meta, TikTok, Snapchat, Taboola and Outbrain) through their official APIs, using OAuth for Google, and syncs them into one view about every 15 minutes. You can give each client its own workspace and assign team roles so a media buyer only sees the clients they run, without anyone sharing platform logins. Our case study on onboarding client accounts without sharing a login shows how one agency did it.

Wavo, the AI copilot, can read across those accounts and propose budget or status changes that you approve before anything happens. Your Google manager account stays the home of access and billing, and Wevion becomes the place where you compare and act across every platform.

Key takeaways

• A Google Ads manager account (formerly MCC) is a separate umbrella account, not an upgrade
• Time zone and currency are permanent, so choose them with finance
• Linking does not change client users or give you ownership; the client grants ownership
• Give most people Standard access, and keep at least two named administrators
• Consolidated billing needs a paying manager and monthly invoicing, and isn't open to media agencies
• Use account labels, shared negative lists, cross-account conversions and bid strategies deliberately
• Enforce 2-Step Verification and allowed domains with security mandates from day one
• Before unlinking, make sure the client has its own admin and move campaigns off shared bid strategies
