When an agency runs campaigns from its own ad account, everything the campaign learns stays with the agency. Audiences, conversion history, the pixel that took months to train — all of it walks out of the door when the engagement ends.
How it should work
You own the ad account and the business manager. You grant the agency partner access, which can be revoked in one click. Billing sits on your card, so there is no markup hidden in a media buying fee.
What to check in the contract
Who owns the account, who owns the creative, what the notice period is, and whether reporting shows spend against leads rather than impressions. If any answer is vague, ask again before signing.
