Short answer: You should own your ad accounts. Your business should hold the Google Ads account, the Meta business portfolio and ad account, GA4, Merchant Center, Tag Manager and your pixel or datasets, and your agency should work inside them with partner or manager access. If the agency owns them, you can lose years of history, audiences and conversion data when you part ways.

Key takeaways
- Ownership means your company is the top level owner or admin of each account, not just a user someone added.
- Agency-owned accounts look fine day to day. The problem only shows up when you leave, and then it is expensive.
- What you lose is not the ads. It is the conversion history, audiences and learning that make the ads work.
- Agencies do not need ownership to do their job. Manager links and partner access give them everything they need.
- If your agency owns your accounts today, ask for admin access and a transfer now, while the relationship is good.
This question usually comes up at one of two moments: when you are signing with a new agency, or when you are trying to leave one and discover you cannot take your accounts with you. The first moment is much cheaper than the second.
Most agencies are not trying to trap anyone. Agency-owned setups often happen by accident: the agency created the account quickly to get started, used its own business portfolio because it was convenient, and nobody revisited it. The fix is simple if you handle it early.
Why should you own your ad accounts and not your agency?
Because the accounts hold data that belongs to your business and keeps getting more valuable over time. Your agency is a supplier. Suppliers change. Your conversion history, customer audiences and tracking setup should not change with them.
Think of it like your domain name or your bank account. You would not let a web agency register your domain in its own name, even if it built your site. Ad and analytics accounts are the same kind of asset.
Here is what "you own it" means for each platform:
| Asset | What ownership looks like |
|---|---|
| Google Ads | The account sits under your own manager account or has your company login as admin. Billing runs through your payments profile. |
| Meta business portfolio (formerly Business Manager) | Your company owns the business portfolio. Your ad account, Facebook Page and Instagram account are owned by that portfolio, not by the agency's. |
| Pixel and datasets | Created inside your business portfolio, then shared with the agency. |
| GA4 | The Analytics account and property sit under your company's Google login, with at least two people at your company as administrators. |
| Google Shopping (Merchant Center) | Your company is admin of the account that holds your product feed and verified website. |
| Google Tag Manager | The account and container are owned by your company, with the agency added as a user. |
A good rule of thumb: if your agency disappeared tomorrow, could someone at your company log in to every one of these as an admin without asking anybody? If the answer is no for any of them, you do not fully own it.
Ownership tied to one employee's personal Gmail is almost as risky as agency ownership. Use a shared company address and keep at least two admins on every account.
What does an agency-owned setup look like, and what do you lose?
An agency-owned setup is one where the account was created inside the agency's own structure, and you only have the access the agency chose to give you, or none at all. Common versions:
- Your Google Ads account was created under the agency's manager account and you have no admin user of your own.
- Your ad account and pixel live in the agency's Meta business portfolio, and your business only has partner access, or none.
- Your GA4 property sits inside the agency's Analytics account.
- Your ads are billed to the agency's card and you pay the agency, so the payment profile is theirs.
Nothing feels wrong while you work together. The cost appears when you leave. If the agency will not hand the accounts over, or the platform does not allow it, you start again in a fresh account. What you lose:
- History. Years of performance data, search terms, tests and what worked. Your next agency has nothing to learn from.
- Learning. Smart Bidding and Meta's delivery system use your past conversions to decide who to show ads to. A new account starts with none, so performance is usually weaker and less stable for the first weeks.
- Audiences. Remarketing lists, website visitors and lookalike or similar audiences built from the old pixel or tag stay with the old account.
- Conversion data. Conversion actions, offline conversion imports and the record of which campaigns drove sales.
The setup
Say you spend €10,000 a month on Google Ads at a 4x return. After three years you switch agency and find your account sits in the old agency's manager account, billed to their card.
The cost
You open a new account. If the return dips to 3x for two months while bidding relearns, that is €20,000 of revenue gone (2 months x €10,000 x 1x lower return), before counting the lost audiences.
How does agency access work when you own the accounts?
You own the account and grant the agency access. Every major platform is built for this, so there is no technical reason an agency needs to own anything.
- Google Ads: your account is linked to the agency's manager account. The agency manages campaigns from there, and you can remove the link whenever you want.
- Meta: your business portfolio adds the agency's business portfolio as a partner and assigns it the ad account, pixel or datasets, and Page with the permissions it needs.
- GA4, Tag Manager and Merchant Center: you add the agency's people as users with the access level they need, often editor or admin for the person running tracking.
The agency gets full working access. You keep the keys. When the relationship ends, you remove the link or the partner, and everything stays where it was.
A common mistake is giving the agency the same top level ownership role you hold, then forgetting about it. Give enough access to do the work, and keep a record of who has what.
How we work
PPC management services in accounts you own
We run your campaigns inside your own Google Ads and Meta accounts through manager and partner access. If you leave, you keep everything.
See our PPC management servicesWhat should you do if your agency currently owns your accounts?
Ask for ownership now, in writing, while the relationship is working. Most agencies agree quickly, especially when you frame it as housekeeping rather than a sign you are leaving.
What can be moved depends on the platform, and the rules change, so check each platform's current help pages before you start. In general terms:
| Asset | What usually happens |
|---|---|
| Google Ads | An account can be unlinked from the agency's manager account and linked to yours. You need admin access first, and billing must move to your own payments profile. |
| Meta ad account | An ad account owned by the agency's business portfolio usually cannot simply be moved into yours. The common fix is a new ad account in your own portfolio, with the agency as partner. |
| Meta pixel and datasets | Often cannot change owner. The agency can share it with your portfolio for now, but plan to set up your own and run both side by side for a while. |
| GA4 | A property can usually be moved to another Analytics account if the person doing it is admin on both. |
| Tag Manager | Ask to be made admin. If that is not possible, export the container and import it into one you own. |
| Google Shopping (Merchant Center) | If it sits under an agency's advanced account, ask for admin access and for it to be separated so you control it directly. |
Ask for ownership in one email
- List every account: Google Ads, Meta business portfolio and ad account, pixel or datasets, GA4, Tag Manager, Merchant Center.
- For each, ask the agency to add your company login as admin, or to transfer ownership where the platform allows it.
- Ask them to move billing to your own payment method.
- Ask for a written list of anything they cannot transfer, and an export of key data (campaign structure, conversion setup, audience definitions) for those.
- Set a date, two to four weeks out, and confirm each item when it is done.
If an account truly cannot move, set up your own version in parallel before you leave, so your new pixel or tag builds data while the old one still runs.
Do not wait until you give notice. Transfers need the agency's cooperation, and that is easiest to get while you are still a happy client.
What should the contract say about account ownership?
One short clause is enough. It should say you own the accounts and data, the agency has access only, and the agency will help hand over when the contract ends. For example:
"All advertising, analytics and tracking accounts, including their data, audiences and conversion history, are owned by the Client. The Agency receives access only for the term of this agreement and will, on request or at termination, transfer any accounts it created on the Client's behalf and remove its own access within 10 working days."
Have your own lawyer check the wording against the rest of the contract. The point is that ownership is written down before work starts, not argued about later.
What to do next
Check who owns each account today, fix anything that is not in your name, and get the clause into your next contract.
- Log in with a company login to Google Ads, Meta, GA4, Tag Manager and Merchant Center, and confirm you are admin or owner in each.
- Send your agency the ownership email above for anything you do not control.
- If you are about to hire, raise ownership early. It is one of the questions to ask a digital marketing agency, and it matters just as much when you are working out how to outsource digital marketing in general.

Frequently asked questions
Look at the account's access and security settings, which list users and linked manager accounts with their access levels. If no one from your company has admin access, or the only manager account is your agency's, you do not fully control it.
It is worth asking why. Sometimes it is just habit or convenience. If the agency refuses to put the accounts in your name when you ask, treat that as a serious warning.
It can, but it complicates handover, because billing is tied to the agency's payment details. Paying the platform directly with your own card or invoicing is cleaner and keeps the account fully in your hands.
Yes. They should sit in your own business portfolio, with the agency added as a partner. Losing access to your Page is harder to fix than losing an ad account.
The campaigns live inside your account, so they stay with you when the agency's access is removed. That is exactly how it should work.
