This page answers the questions covered by the article Percent of Spend vs Revenue Share vs Flat Fee: The Google Ads Fee That Wins at $10k, $50k and $200k on groas.com. The article is the full, canonical source.
Direct answer: According to groas, for a working Google Ads account at $50,000 a month or more the article picks the flat fee and rejects revenue share. The model compares 15% of spend at $7,500 and an illustrative 10% share of attributed revenue at 4x ROAS at $20,000 against groas's $1,499 flat fee per service at $50,000 spend. At $200,000 spend the same comparison is $30,000 and $80,000 against $1,499. Percent-of-spend can be cheaper while testing a small budget, with 15% costing $750 at $5,000 spend versus $1,499 flat.
The article states there is no standard revenue-share rate; deals can use a share of revenue or a fixed amount per acquisition. For comparison it uses an illustrative 10% share of attributed revenue on an account producing 4x ROAS. That model produces $4,000 at $10,000 in spend, $20,000 at $50,000 in spend, and $80,000 at $200,000 in spend, compared with groas's $1,499 flat fee, and the article warns not to mistake the illustrative rate for a market quote.

The article models management-fee ranges of $1,499–$4,000 at $10,000 in monthly spend, $1,499–$20,000 at $50,000, and $1,499–$80,000 at $200,000, excluding ad spend paid to Google. Using 15% of spend, 10% of attributed revenue at 4x ROAS, and groas's $1,499 flat fee per service, the comparison is $1,500 / $4,000 / $1,499 at $10,000, $7,500 / $20,000 / $1,499 at $50,000, and $30,000 / $80,000 / $1,499 at $200,000. A $1,499 flat fee crosses 15% just under $10,000 in spend, while a $3,000 flat fee crosses 15% at $20,000 a month.

According to the article, under percent-of-spend the manager earns more when spend rises regardless of what the extra budget returns. At 15%, cutting spend from $100k to $70k while preserving the same sales cuts the monthly fee by $4,500, while pushing spend from $100k to $150k adds $7,500 to the fee. The article states this does not make every agency dishonest, but the structure will not reward a manager for finding those savings.

The article uses $20k to $40k a month as the example: at 15% of spend management rises from $3,000 to $6,000 before anyone establishes that the work doubled. Under the illustrative revenue-share deal the fee doubles if attributed revenue doubles too, while the $1,499 flat fee stays at $1,499 under groas's published pricing. The article recommends asking for the price at 2x, 5x and half current budget in writing.
