Meta Will Force Ad Buying Solutions to Separate Spend From Fees
From 3 February 2027, Meta requires ad buying solutions operating through its developer platform to tell you the amount they spent on Meta advertising, separate from their fees, and the fee structure they charge, if you ask. The condition is that you ask.
The obligation sits in section 10 of Meta’s Developer Policies, under a block headed Transparency and marked effective 3 February 2027. If an end advertiser requests it, an ad buying solution must disclose the amount it spent on Meta advertising on that advertiser’s behalf, separate from its fees, and the associated fee structure it charges. The same clause covers campaign configuration, campaign settings and post-campaign reporting, using Meta’s terminology rather than a house translation.
Two lettered clauses beside it matter as much. Clause b of that block reads, in full: “Display Meta ad campaign reporting separately from other publishers.” Clause c states that Meta may require documentation from a provider to ensure compliance with these terms, and may require it to disclose who its end advertisers are. Separately, and already in force with no effective date attached, section 10 forbids combining multiple end advertisers or their Meta business assets in the same ad account without meeting Meta’s stated requirements or written approval.
Our math: a blended invoice does not just obscure the fee, it breaks the arithmetic. A line reading media and management, $6,000 CAD, against 40 deposits, produces a cost per deposit of $150 CAD. Split it into $4,500 CAD of working spend and $1,500 CAD of fee and the media cost per deposit is $112.50 CAD, while the delivered cost is still $150 CAD. Those two numbers answer different questions. The first tells you whether the channel works. The second tells you whether the arrangement does. One combined line answers neither, because the deposits are known and the media spend is not, and the numerator is the half the invoice withholds.
Our read: this is reactive, not proactive. Meta states that unless required by law it does not disclose this information proactively, and that where it identifies or suspects a violation it may provide the disclosure itself on the end advertiser’s request, and may but is not obliged to notify the provider. So the operative question for an owner-operator is not whether the policy protects them. It is whether they have ever asked, and whether the provider they are asking operates through Meta’s developer platform, which is what these policies bind.
Send this sentence: please provide my Meta advertising spend separate from your fees, and your fee structure, for the last twelve months.
