If you want to transfer a Google Ads account from an agency, you are not moving a file. You are moving control. Take administrator access in your own login first, run your own conversion tracking beside the agency's, and only then remove the agency's link. The account's campaign history stays where it always lived.

Whose account is it, and why does that decide everything?
Most owners say "the agency has my ad accounts" and mean one of two very different things.
In the first, you opened the account, put your card on it, and gave the agency access. The agency is a guest. Leaving is a matter of taking the guest's access away, and nothing about your history has to move.
In the second, the agency opened the account under its own manager account, paid for the spend and billed you for it. Here you may not have a single login that can administer the account. You cannot unlink what you cannot administer, so the first job is not technical at all. It is a written request, to the agency, for administrator access in your own Google login.
Find out which one you have before you say anything about leaving. Ask for the account ID, the list of people with access, and the name of the manager account it sits under. An agency that answers that in a day is telling you something. One that needs a week is telling you something else.
What do you collect before anyone touches a setting?
The ad account is the visible part. The things that decide whether your numbers survive sit beside it.
| Asset | What it holds | What to confirm |
|---|---|---|
| Google Ads account | Campaigns, budgets, search terms, change history | You are an administrator, and you know which manager account it is linked to |
| Conversion actions and tags | What counts as a win, and the record of it | Whose tag fires on your site, and whether it comes from the agency's manager account |
| Tag container | Every tracking tag on the site | The container lives in an account you own |
| Analytics property | Sessions and goals, linked to the ads | Your login owns the property, not the agency's |
| Meta ad account | Campaigns and spend | Which business portfolio owns it |
| Meta pixel and audiences | Event history and the lists built from it | Which portfolio owns them, and who has been given access |
| Payment method | Whether spend continues | Your card is on file before the agency's ends |
Take a screenshot of each screen before changing anything. It costs ten minutes and it is the only record of how the accounts were set up on the day you left.
In what order do you move the Google Ads account?
The order matters more than the speed. Each step protects the one after it.
- Get administrator access with your own login. Ask the agency to invite you, or confirm that you already have it. Without it, nothing below is yours to do.
- Put your own billing in place. Add your payment method and confirm it is accepted while the agency's is still active, so the day of the switch is not the day spend stops.
- Install your own conversion tracking, and leave the agency's running. This is the step owners skip. Google's help page on unlinking says that when an account stops using a manager's cross-account conversion tag, "that tag will no longer record conversions for clicks that take place after the account was unlinked." Clicks from before the unlink keep being counted for the conversion window, which Google describes as typically 30 days. If you had your own tag before, it resumes. So put yours on the site first, then keep the old one in place for the full window.
- Unlink the manager account. Google says a user with administrative access to either account can do it, and that the account keeps its own record: "The individual account won't lose its own account campaign history or access to any Google Ads features."
- Check the first week against the last. Compare spend, clicks and conversions for the seven days before and after. A drop in recorded conversions that is not matched by a drop in leads usually means a tag, not performance.
That fourth step is the one people fear, and it is the safest of the five. Campaign history sits in the account. What you can lose is the tracking that feeds it.
How do you move the Meta side without breaking the pixel?
Meta organises everything under a business portfolio, and each asset has an owner. The question to settle is not "can the agency hand it over" but "which portfolio owns it today". The pages on giving a partner access to business assets in Meta's help centre are where partner access is managed, and the idea behind them is simple: an owner shares access with a partner, not the other way around.
What you want is your portfolio as the owner and the agency as a partner. If it is the reverse, you are the guest in your own advertising, and the agency can remove you.
Work through four checks in your own portfolio settings:
- The ad account, the pixel and your audiences each list an owner. It should be your portfolio.
- The agency appears only as a partner, with only the access it needs.
- Your Page is owned by you, not by the agency's portfolio.
- Your payment method is yours.
If any of the four fails, the fix is a request to the agency, in writing, naming the asset. Do not delete a pixel or an audience to "start clean". The event history behind them is the evidence your next agency will build on, and it cannot be recreated.
What does losing this history actually cost?
More than the agency's invoice suggests. In an industry survey distributed through Businesswire, 71% of brands said they were frustrated by how hard it is to demonstrate marketing ROI. A new agency starting from an empty account has one fewer way to answer that, because the baseline it needs is the history you just discarded.
Conversion history is what lets you say which campaigns produced a customer rather than a click. Without it, the first ninety days with the next agency are spent rebuilding the evidence you already paid for once.
What should the agreement say, so this never comes up again?
Put the ownership in the contract on day one. It costs nothing to write and everything to retrofit.
- The company owns every ad account, pixel, tag container and analytics property, and the agency is added as a user or partner.
- The agency's manager account links to yours, and either side can unlink at any time without notice.
- On exit, the agency hands over a written list of every asset and login within a set number of days.
Our contract terms guide covers the clauses that matter, and the week-one onboarding checklist shows what to grant at the start and what to keep. If you are already planning the exit, switching agencies without losing a quarter sequences the whole move, and the same logic applies to the website your agency may also host.
The test is the same one that applies to any asset. If your agency stopped replying tomorrow, could you still log in, still adjust a budget, and still read last quarter's results? If not, you do not own your advertising yet. You rent it, and the rent is invoiced as management.
