The brand. Create the Google Ads account, Merchant Center, conversion tracking and GA4 property under the brand's Google login, and let the agency work through a manager account link you can remove. Put that in the contract with month to month terms and a dated exit. An agency that resists any of it is pricing in your inability to leave.
This page is for stores spending $10,000 a month or more on Google Ads in the US, or £5,000 or more in the UK, about to sign or renew with an agency. At that spend the account is not a login. It is two years of change history, the conversion data Smart Bidding runs on, the audience lists, the Merchant Center claim on your domain and Google's own invoices. A Google Ads account has no owner field. Control is three things: who holds Admin access, which manager account holds the ownership flag, and whose payments profile pays Google.
Plan the exit before you sign, because you will probably use it. In Setup's sixth annual Marketing Relationship Survey, released late 2024 with more than 400 brand and agency contributions, 40% of clients said they would switch agency partners within the next six months. The question is not whether you leave. It is what you take with you.
There is still no page one worth reading on this. As of September 2026, no phrasing of the question has a crawled search result in Ahrefs for the US or the UK. Google shows its own help page and eight agency posts; none that we read leads with the three Google rules that decide whether an ecommerce account survives a handover: the Merchant Center URL claim, the cross-account conversion rule and the GA4 move rule. We take over accounts other agencies built. This is the ownership map we wish each had started with.
The ownership map: who creates what, who keeps what
| Asset | Created under | You keep | The agency gets | If the agency holds it instead, on exit you lose |
|---|---|---|---|---|
| Google Ads account | Your company Google login and your payments profile | Admin access, on at least two company logins | Access through its manager account link | The account itself: campaigns, 2 years of change history, conversion history, audience lists. A replacement starts Smart Bidding from zero |
| Manager account (MCC) link | The agency's own manager account | The right to unlink at any time, which needs Admin | Day to day working access | Nothing, if the link is all it holds. If the manager created the account or was given ownership, it controls who has access to your account, and every manager above it inherits that |
| Conversion tracking (conversion actions, Google tag, GTM container) | Your Ads account and your Tag Manager account | The conversion actions and their history | Standard access to build and edit them | Cross-account actions live in the manager account and cannot be edited from yours. A tag container under the agency's login cannot be edited after exit |
| GA4 property | Your Analytics account | Administrator on the account | Editor on the property | The property and its data. Moving it needs Administrator and Editor on both accounts, so it moves only if they agree |
| Merchant Center and the website claim | Your company Google login | Admin, and never the agency as the only admin | Standard, or Admin alongside yours | The claim on your URL (one account per URL), the feed, product data history and any reinstatement history |
| Product feed source (Shopify Google & YouTube app, or a feed app) | Your Shopify admin, your app subscription | Ownership and billing of the app | Staff or collaborator access | Feed rules, supplemental feeds and title rules built inside an app on the agency's subscription |
| Payments profile and billing | Your payments profile, Google bills you directly | Google's invoices and payment history | Billing access at most | The record of what Google charged, as distinct from what you were invoiced |
| Audience lists (remarketing, customer match) | Your Ads account, not manager-level shared lists | The lists and their membership | Use of them in campaigns | Lists built and shared from the manager account belong to the manager account |
Each row is a separate asset and can be lost on its own. A brand can hold Admin on the Google Ads account and still find on exit that the conversion actions belong to the agency's manager account and the Merchant Center claim sits in a login nobody at the company can open.
The four things that decide whether you can leave in 30 days
1. The Google Ads account and the Merchant Center are created under your own Google login. Not the agency's, and not an employee's personal Gmail. Google Ads Help is exact about the alternative: "If a manager creates a new account, the manager will automatically become the owner of that account." Ownership is transitive, so "all the managers above your manager account will also have ownership", which matters when your agency white-labels or sits under a parent network. Google's own guidance is that a manager "should be made owner if and only if the manager account requires these privileges". Running campaigns does not require them.
2. The agency links in through a manager account it uses, not one that owns you. Google Ads Help states that Admin users "can accept and reject manager account link requests" and "can unlink manager accounts", while Standard users can see the user and manager lists but cannot change access levels, accept a link request or unlink a manager. Ownership does not take the data away, either: owners "do not take data ownership or administrative rights away from client accounts", and a client Admin "can always unlink a manager with ownership". Every one of those sentences depends on your company login holding Admin. If nobody at the company is an Admin user, there is nobody who can click unlink.
3. Conversion tracking and the GA4 property stay yours. Google's rule is exact: "A Google Ads account can use account-specific conversions or cross-account conversions. It can't use both." Cross-account actions are created at the manager level, and client accounts "will be able to see, but not make changes to" them. A purchase action built in the agency's manager account means your account does not own its own conversion setup, and Google gives the manager's tag priority over yours. For GA4, Analytics Help states that "to move a property, you need the Administrator and Editor roles for both the source and destination accounts", so a property created in the agency's Analytics account moves only with their cooperation.
4. The contract says month to month with a dated exit. A 6 to 12 month term is not a service feature. It is the agency's protection against the first three items being true. Month to month, or a short initial term with a dated end, 30 days' notice, and a written handover list are what make the ownership above worth anything.
These four are terms, not evaluation criteria. The questions that sort agencies before this point are on our guide to how to choose a PPC agency.
How to check who owns what right now
Six read-only checks, about 20 minutes, no agency involvement. Google Ads, Admin, Access and security: your company login appears as Admin, and the Managers tab lists every linked manager account with an Owner column; only one can say Yes. Google Ads, Goals, Conversions, Summary: a purchase action you cannot edit is a cross-account action owned by the manager account. Google Ads, Billing, Settings: whose payments profile pays Google. Merchant Center, People and access: who holds Admin, and which agencies sit in the Partners table. Merchant Center, online store verification: whether the claim on your URL sits in an account you can open. GA4, Admin, Account access management: which Analytics account holds the property, and who holds Administrator on it. Write the six answers down. They are the baseline for every contract conversation that follows.
How brands lose ownership, hardest to undo first
The agency created the Google Ads account inside its own manager account at onboarding. Fastest for the agency, most expensive for you. Google's rule makes the agency's manager the owner automatically, and an account with no company Admin user has nobody who can unlink it. Google does document a transfer: an existing Admin invites your login as Admin, then removes their own access. Only an Admin can send that invitation, so the party you are leaving holds the button. The same applies to an account under a former employee's or freelancer's personal login. Recovery means negotiating that invitation or building a replacement.
The Merchant Center was created by whoever set up Shopping first, under their login. Merchant Center Help states that "a single URL can only be claimed by one account". While their claim stands, your products run through their account.
Tracking was set up in the agency's accounts to save a week. Cross-account conversion actions, a Tag Manager container under the agency's login, a GA4 property in the agency's Analytics account. Each was quick on day one and is a dependency on day 400.
Billing runs through the agency. The agency's card pays Google and rebills you with the fee folded in. Google's transparency requirements oblige third parties to report "the exact amount charged by Google, exclusive of any fees that you charge", to disclose any management fee "in writing before each first purchase" and "on all customer invoices", and to provide customer IDs "when requested". Direct billing turns that request into a receipt.
The fix before you sign, and what changes at $50,000 a month
All of this is DIY at any spend. Creating the Google Ads account, the Merchant Center and the GA4 property under a company login takes about an hour; then grant the link and the roles in the table above, and let the agency link in once setup is done. Put Admin on at least two company logins: Google warns that an account with only one administrator can lose access to its tags if that user becomes unavailable.
If the account already exists under the wrong login, the fix is a decision, not a click. Decide with your counsel and the agency whether the account transfers or a replacement is built, get the decision dated in the contract before work starts, and validate afterwards that tracking still records correctly with our Google Ads and GA4 tracking audit checklist. A moved purchase action that silently stops counting is the most expensive outcome of all. UK stores: the mechanics are identical, English law on the contract changes nothing about which login holds the account, and if a Comparison Shopping Service partner set up your Merchant Center, confirm it sits under your login.
At $50,000 a month and above the same rules meet three things that do not exist at $10,000. First, monthly invoicing. Google Ads Help states that "a manager account is required for Ads accounts using monthly invoicing" and, for invoicing or a credit line, to "ensure that manager account ownership is enabled". That is the one legitimate reason an agency asks to own your account. Do not grant it to theirs: create your own manager account, make it the owner, apply for invoicing under it, and let the agency's manager link to the account without ownership. Second, more accounts. Separate US and UK accounts and a Merchant Center multi-client account, which Merchant Center Help says is what lets several accounts share one URL claim, mean more places to hold Admin and more people touching them, so review the user lists quarterly. Third, losing history costs more. Google Ads Help says Smart Bidding performance "typically converges to your new goal within 1 to 2 conversion cycles" and that "conversion data from previous campaigns can help drive faster results". At $50,000 a month with a seven day conversion cycle, that is roughly $12,000 to $23,000 of spend under an algorithm that has forgotten what it knew.
What losing the account costs at your spend
Round numbers, substitute your own. A store spending $30,000 a month signs a 12 month term at 15% of spend, the middle of the 10% to 20% of spend that WebFX's PPC pricing page reports as typical (our own rate card is on the Google Ads management pricing guide). The fee is $4,500 a month. At month three the fit is wrong. Under the 12 month term, $40,500 of remaining fees and $270,000 of managed spend stay with an operator you want to leave. Under month to month with a 30-day exit, the same discovery costs one month.
Now add ownership. If the account, tracking and audiences belong to the agency, leaving means a new account with no conversion history. Google says Smart Bidding performance typically converges to a new goal within one to two conversion cycles. For a store at $30,000 a month with a seven day conversion cycle, that is 7 to 14 days, about $7,000 to $14,000 of spend. If the account runs 20% below its normal efficiency in that window, an assumption to replace with your own number, a store at 3.0x ROAS gives up about $4,200 to $8,400 of conversion value. The audience and negative keyword lists and the 2 years of change history stay behind, so the new operator diagnoses blind. And the old account does not wait: Google Ads Help states that an account inactive for more than 15 months with no spending is canceled automatically, and a canceled account's remarketing and Customer Match lists are closed, then emptied about a month later.
The contract costs nothing to fix. The account structure costs an hour. Both are cheapest before the first invoice.
What the contract must say
Read the contract as if the engagement has already failed, because that is the only time these lines are used. We are not lawyers; have yours review the wording. These are the points to insist on.
| Clause | What it should say |
|---|---|
| Ownership | Every account and its data are your property: the Google Ads account, conversion actions and history, audience lists, the Merchant Center account and URL claim, the GA4 property, the Tag Manager container, feeds and feed rules, and all creative. All were or will be created under your company login. Any account already created under another login is transferred before work starts: its current Admin invites your login as Admin and removes their own access, and the transfer is dated |
| Access | The agency works through a manager account link or named users. You hold Admin on Google Ads, Admin on Merchant Center and Administrator on the GA4 account for the whole engagement. The agency is never the only admin anywhere and its manager account is not given ownership |
| Term and exit | Month to month, or a short initial term with a dated end. 30 days' written notice from either side, no automatic renewal into a fixed term |
| Handover | Within the notice period: agency access removed, campaigns documented, conversion and feed setup documented, and exports handed over (search terms, change history, negative lists, feed rules) |
| Reporting and billing | You hold reporting access for the whole engagement. Google's charges are reported exclusive of fees at account level, and the management fee is disclosed in writing before the first purchase and on every invoice; both are Google's own requirements of third parties. Google bills your payments profile directly, or invoices a manager account you own |
| Data use | Your first party data and audiences are used for your account only, and nothing is retained after exit |
How we run ownership at Just Lead Market
We sell Google Ads management for ecommerce brands, so read this section knowing that. The model is the one on this page, on every account. Test any other proposal against it.
The Google Ads account and the Merchant Center are created under the brand's own Google login. We link in through our manager account; the link is ours to use and yours to remove, and you keep Admin. Conversion tracking is built in your account, not ours, and the GA4 property lives in your Analytics account. The terms are published on our service pages: month to month, a 30-day exit, no long contracts, and 100% ownership, your account and your data. Audits run on read-only access you can revoke in a minute, and you keep the findings whatever you decide.
The reason is practical. Accounts we take over arrive with the previous operator's structure still in them: on one US ecommerce account, ten automated rules built by the previous agency between December 2019 and October 2022 were still there, inactive, when we opened it. A clean ownership model lets the next operator see that, and lets you fire us in 30 days if we earn it.
Already signed, and the agency owns the account?
Do not open the argument yet. Export what you can from the access you have: search terms, change history, the conversion action list, negative keyword lists, the feed. If the question is whether the agency is performing rather than what it holds, run our check on whether your Google Ads agency is doing a good job first. Then decide whether you are negotiating a transfer or building a replacement; the timelines differ and the agency's incentives run the other way in both. The handover mechanics, from unlinking the manager account to moving the GA4 property and reclaiming the Merchant Center URL, are in the switching Google Ads agencies handover guide.
