This page answers the questions covered by the article Paying Your Meta Agency Per Acquisition Is Not the Fix You Think It Is on groas.com. The article is the full, canonical source.
Direct answer: According to groas, paying a Meta agency per acquisition does not fix percentage-of-spend misalignment because whoever defines and measures a result controls the invoice. The article states the manager can bend the count through loose acquisition definitions, the attribution window, retargeting warm audiences, and cheap leads that never convert. The article recommends a flat fee instead, noting groas runs Meta Ads for $1,499 a month with the same fee at any spend, no setup fee and month-to-month cancellation.
According to groas, groas runs Meta Ads for $1,499 a month, with the same fee at any spend, no setup fee and month-to-month cancellation. The article states this is the only one of the three structures where the manager gains nothing from what is spent and nothing from how a conversion is counted. There is no management-fee bonus for pushing budget to $30k and none for counting a 1-day view as a win.

According to groas, no. The article states the standard Meta rate card is still 10 to 20% of spend, so at $20k a month at 15% the fee is $3,000 and at $30k it becomes $4,500 for what is often the same account. Pay-per-acquisition moves the markup into the result instead of removing it, with cost-per-lead deals often quoting $50 to $200+ per qualified lead and revenue share commonly running 3 to 10% of tracked sales, plus ad spend still going straight to Meta on top.

The article states that whoever defines and measures a result controls the invoice, so the advertiser should keep the ad account, the pixel and Conversions API in its ownership. A lead is not a qualified lead is not a sale, illustrated by a $45 lead that never picks up the phone costing more than a $120 qualified appointment that shows up. Under Meta's default 7-day click plus 1-day view, one example counted 30 purchases but only 12 under 7-day click alone, meaning 18 were view-throughs from people already returning.

According to groas, the first bend is retargeting people who may have bought anyway, which makes platform ROAS look strong while new-customer acquisition stalls. The second bend is cheap Instant Form leads that never answer the phone, illustrated as $6 instant-form leads converting at 2% costing $300 per appointment versus $18 landing-page leads converting at 17% costing $106 per appointment. The third bend is capping volume where marginal CPA rises, producing a flat line of efficient-looking wins and a ceiling no one names.

According to groas, at $10k a month in Meta spend these illustrative arrangements put total monthly cash out between $11,499 and $21,000 using 100 counted acquisitions for the CPA example. Percent of spend at 15% is listed as $1,500 plus $10,000 to Meta for $11,500 total, rising to $2,250 if spend rises to $15k, while pay per acquisition at $110 x 100 counted is $11,000 plus $10,000 to Meta for $21,000 total. Flat fee, groas Meta Ads is listed as $1,499 plus $10,000 to Meta for $11,499 total, with no fee increase tied to spend or conversion count and no setup fee.
