An agency reselling paid search is taking responsibility for a client's money in a system it does not operate, and every difficulty in this arrangement comes back to that. Who owns the advertising account, who holds the conversion history, who is named on the billing, who speaks to the client when performance falls, and what the client is entitled to see. Answer those five before the first campaign and the model works well; leave them and the first bad quarter is unmanageable.
The client should own the advertising account
The cleanest structure is the advertiser owning their own account with your agency as manager and the fulfilment partner added beneath. The conversion history has real value, it takes months to rebuild, and a client who discovers they cannot take it with them has a legitimate grievance against you rather than against your supplier. Accounts pooled inside a partner's manager are convenient for the partner and a liability for you.
Decide what the client is told, and be consistent
Some clients neither know nor care who executes; some would consider it material. What is not defensible is a claim of in-house expertise that would embarrass you if the client learned otherwise. Settle the story before you sell, keep it true, and make sure nobody on your team is improvising a different version on a call.
Margin has to survive the work you will actually do
Reseller pricing looks comfortable until you count the client calls, the reporting you rewrite, the strategy questions the partner will not answer and the escalations when results slip. Price for the account management you will genuinely provide, not for the pass-through. Agencies that price on the partner's fee plus a percentage discover the real cost in the third month.
Quality varies enormously and you carry the reputation
Before committing clients, run one account and read the search terms, the negative lists, the account structure and the conversion setup yourself. A partner that has bundled your client into a template with generic negatives is producing work you would not accept from an employee. Your client will not distinguish between you and them, so the diligence is yours to do.
Write the exit into the contract
What happens to the accounts, the conversion data, the creative and the landing pages when either side ends the arrangement, and how much notice applies. The moment this matters is the moment relations are worst, which is exactly why it has to be agreed while they are good. A partner unwilling to put it in writing is telling you what the exit will be like.
Questions people ask about white label ppc services
Who should own the ad account in a white label arrangement?
The advertiser, with your agency as manager and the fulfilment partner added beneath. Anything else means the conversion history, which takes months to rebuild, sits with somebody the client has no relationship with.
Do we have to tell the client the work is outsourced?
You have to avoid saying something untrue. Many clients neither ask nor care; what damages a relationship is a claim of in-house capability that turns out to be false. Decide the story, keep it accurate, and brief your team.
How do we judge a white label partner?
Run one real account first and inspect it yourself: structure, search terms, negatives, conversion setup. Templated work with generic negatives is what you would be reselling, and the client will hold you responsible for it.
Is the margin worth it?
Only if priced for the account management you will genuinely do. The pass-through looks profitable until the client calls, the report rewrites and the escalations are counted, which is usually by month three.
