Whoever created the ad account controls it. If your agency set up your Google Ads or Meta account inside their own manager account with their billing and their logins, then the account, and every dollar of performance history in it, effectively belongs to them. If it was created under your email with them invited in as a manager, it is yours.
Most owners have never checked which of those two worlds they live in, because as long as the ads are running, both worlds look identical. The difference only appears on the day you leave, and by then it is expensive.
Why the history matters more than the account
An ad account is not just a container for campaigns. It is years of accumulated learning: which keywords produced calls, which ads got clicked, what a lead costs in your market in February versus July, the conversion data that Google’s automated bidding uses to find your next customer. That history is why a mature account outperforms a brand-new one running identical ads. When an agency keeps the account, you do not just lose access to some settings. You start over from zero, paying full tuition again for lessons your money already bought once. Owners switching away from certain large ad platforms report exactly this: cancel the service, lose the account, keep nothing, sometimes without ever having seen inside the account at all.
Find out today: the ownership checks
- Google Ads: ask for your Customer ID (a ten-digit number). If nobody can tell you your own Customer ID, that is your first red flag. Then confirm you have admin access under your own email, not a login the agency created and can revoke. Check whose billing is on the account: if the agency’s card pays Google directly and rebills you, the account almost certainly lives in their structure.
- Meta (Facebook and Instagram): your ads should run from an ad account inside a Business Manager owned by your business, with the agency added as a partner. If the ad account sits inside the agency’s Business Manager, it is theirs, and Meta generally does not migrate ad accounts between Business Managers.
- The direct question: email your agency: “Please confirm our ad accounts are owned by us, list the account IDs, and confirm we have admin access.” A clean agency answers with a list. A hostage-keeper answers with a phone call about how the accounts are “proprietary.”
If the agency owns your account
You have three moves, in escalating order. First, request a transfer or admin handover in writing; on Google, accounts can often be unlinked from the agency’s manager account and linked to yours with ownership handed over, if the agency cooperates. Second, if they refuse, demand a full export of the data your money produced: search terms, ad copy, conversion history, audience lists you legally own. Some contracts oblige them to provide it; even where they do not, the request creates a paper trail. Third, if you get neither, accept the restart but do it smart: before your access disappears, screenshot everything you can see, note the winning keywords and ads, and stand up a fresh account in your own name so the new history accrues to you forever. It stings once. It never stings again. Our guide to switching agencies without losing everything sequences all of this so you secure assets before you give notice, which is the part most people get backwards.
While you are checking, look at one more quiet asset: your audience and customer lists. Remarketing audiences, uploaded customer files, and pixel data built from your website’s traffic are part of the account they live in. If that account is the agency’s, years of audience-building walk out with them too, which is one more reason the container matters as much as the campaigns inside it.
The arrangement to insist on next time
The industry-standard setup that protects you is simple, and any competent agency can work inside it: the account is created under your business’s email, your billing goes straight to the ad platform, and the agency is linked in with manager access to do their work. They get everything they need to perform. You keep the asset. When we run Google Ads for clients, that is the only structure we use, full admin access and live reporting from day one, because a family business should never have to ask permission to look at its own advertising. It is the same principle running through our whole who owns your marketing assets guide, and it is question number one on the pre-hiring checklist in the agency hiring pillar.
