Google Ads Management Fees | Which Model Is Right

The Google Ads management fee is a separate line item from ad spend. You pay ad spend directly to Google; the management fee goes to whoever runs the account, whether that’s a freelancer or an agency. This page covers the fee models that exist and which side each one favours.

What you pay Google is covered separately on the Google advertising costs page.

The percentage-of-spend model

This is the most common model in the industry: the manager takes a fixed percentage of your monthly ad spend. The logic is that their income grows with your growth.

The problem sits right there. In this structure, cutting the budget lowers the manager’s income. So finding and cutting waste — often the highest-return work in an account — gets financially penalised. The model doesn’t require bad intent; the incentives just point the wrong way.

If you choose this model, build a separate framework for discussing budget cuts.

Fixed scope, fixed fee

This is how I work. How many campaigns, which campaign types, how often changes are made and what gets reported — all defined in writing, with the price following from that.

The advantage is that incentives point the right way: reducing your spend doesn’t touch my income, so I can say what needs cutting without hesitation. If scope grows we discuss the price; it doesn’t rise automatically because spend grew.

The downside is that scope has to be defined clearly upfront — extra work, but it clarifies expectations on both sides.

Hourly and project-based

For a specific piece of work — an account audit, a setup, or a one-off fix — project pricing makes sense.

For ongoing management, hourly gets awkward: tracking time spent is a burden for both sides, and a quickly-solved problem gets paid less, penalising experience.

Performance bonus

Sounds fair on the surface: pay more as results improve. In practice it has two problems.

First, results aren’t entirely under the manager’s control — your product, price, landing page and stock also decide the outcome. Second, if the bonus is measured short-term, it creates an incentive to push the account for short-term gain, which can hurt its long-term health.

It can work as an added component, but I don’t think it belongs as the sole fee structure.

How do we start? First, we discuss scope and I send you the price in writing. You can reach me from the contact page.

Frequently Asked Questions

Is the management fee deducted from ad spend?

No, they’re separate. You pay ad spend directly to Google from your own account; the management fee is paid separately. That separation ensures your full budget goes to advertising.

Does a management fee make sense on a small budget?

Below a certain threshold the fee becomes disproportionate to spend and stops being economical. In that case, Google Ads training and managing your own account may make more sense.

How long should the contract be?

Meaningful results in Google Ads usually take a few months, so I suggest at least three. But avoid long binding contracts that force you to continue.
