Management fee
A management fee is what a store pays an agency or a freelancer for running its ads, on top of what it pays Google for the ads themselves.
How it works
Google charges for clicks and impressions. A PPC agency or a freelancer charges for running the account. The fee usually takes one of four forms, and each pays the contractor for something different:
| Model | How it is set | What raises the contractor’s pay |
|---|---|---|
| Share of spend | A percentage of monthly ad spend | More spend, whether or not it pays off |
| Flat fee (retainer) | The same amount every month | Nothing that happens in the account |
| Pay for results | A bonus or a share tied to revenue or ROAS | The metric named in the contract |
| Hourly | Time actually spent | More hours |
A fee tied to one month’s ROAS rests on a number that moves by itself. For the median store, a typical month’s ROAS sits 16% away from the store’s own median, and its best month brings 3.1× the ROAS of its worst (GetProfit data, 110 stores, June 2025 – June 2026).
The models compared on price: what Google Ads management costs.
Formula
Total cost of the ads = ad spend + management fee
Where you see it
On the contractor’s invoice, separately from Google’s charges. Google’s third-party policies require partners who charge a management fee to tell new customers in writing before their first purchase and to show it on every invoice. Google costs reported to a client must be the exact amount Google charged, without the partner’s fees.
Example
Example store, not client data.
The tableware shop spends 40,000 a month on ads and gets 180,000 in revenue: ROAS 4.5. At a 10% share of spend, the fee is 4,000 and the ads cost 44,000 in total, so revenue per unit of total cost is 180,000 ÷ 44,000 = 4.09. If spend rises to 50,000, the fee rises to 5,000; a flat fee of 4,000 stays at 4,000.
Not to be confused with
- Spend — what Google charges for the ads. The fee goes to the contractor and never appears in the ad account.
Right and wrong readings
- Wrong: “ROAS is 4.5, so every unit we put into advertising returns 4.5.” Right: ROAS divides revenue by ad spend only. With a 10% fee, the example store gets 4.09 per unit of its total cost.
