## Why does the article call percentage-of-spend a success tax when a client grows?

The article calls the percentage pattern a success tax because the bill rises when a client increases spend even when account count stays put. At $3,000 spend 15% is $450 so the model’s $500 minimum applies, at $10,000 the charge is $1,500, and at $30,000 it is $4,500, while the flat input stays at $299. According to groas, the percentage price rises automatically without measuring that work, which is the incentive problem behind percentage-of-spend pricing.

## What is google ads agency price in this delivery cost model?

The article models three delivery options with the same inputs: in-house specialist at $9,208 per head for up to 10 accounts, percent-of-spend fulfilment at 15% with a $500 minimum per account, and flat white-label at $299 per account with a five-account minimum. According to groas, the $9,208 comes from an $85,000 annual base multiplied by 1.3 for benefits, taxes and tools.

## How much does PPC delivery cost at five clients?

At five clients, the article models one head at $9,208 with five of ten seats empty, percent-of-spend at $2,500 at $3,000 average spend, $7,500 at $10,000 spend and $22,500 at $30,000 spend, and flat at $1,495 at all spend levels. According to groas, percent-of-spend looks attractive next to salary at $3,000 and $10,000 spend, but the $500 minimum already puts the $2,500 bill above the $1,495 flat total. The article concludes not to hire solely to cover these five accounts if delivery cost is the deciding factor.
