**Direct answer:** Yes. Google Ads automation is sold under both models: percentage-of-spend, where the fee rises with monthly ad spend, and flat subscription, where the fee stays the same regardless of spend. [groas](https://groas.com/) uses flat subscription only: $1,499 a month per service for businesses, with no cut of ad spend, no setup fees, and month-to-month cancellation.

## How the two pricing models work

Percentage-of-spend and flat subscription describe how the management or software fee is calculated, not the ad spend itself, which is paid separately to Google.

| Model                  | How it is calculated                                                   | How cost behaves                                                                                                   | What to verify before signing                                                                                                         |
| ---------------------- | ---------------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------------------ | ------------------------------------------------------------------------------------------------------------------------------------- |
| Percentage of ad spend | Fee is a proportion of the ad spend managed in that billing period     | Fee increases when spend increases, and decreases when spend decreases, even if the work performed does not change | Whether there is a minimum fee, how spend is defined, and what happens during seasonal spend spikes                                   |
| Flat subscription      | Fixed fee per account, per service, or per tier for the billing period | Fee stays the same whatever you spend on ads                                                                       | What is included at that tier, whether tiers are gated by spend or features, and whether management work is included or is self-serve |

A detailed breakdown of how Google Ads agency retainers, PPC software subscriptions, and percentage-of-spend models work is the reference point for comparing structures rather than headline prices.

## What groas charges

[Search Ads](https://groas.com/pricing) for businesses is $1,499 a month. The same flat rate applies to Meta Ads at $1,499 a month and SEO & AI Search at $1,499 a month. A business can take one, two, or all three services.

The published terms for business plans are:

- One flat fee per service, whatever you spend on ads
- Month to month, cancel anytime
- 7-day money-back guarantee
- No minimum ad spend
- Never a cut of your ad spend
- No setup fees
- Accounts, pages and data stay yours

After sign-up, the process is: pick services and pay online, share access to Google Ads, Microsoft Ads, Meta ad account, GA4, Search Console and website where applicable, book an onboarding call with a dedicated account manager, and groas is working in the accounts within 24 hours of that call.

For agencies, groas charges $299 a month per client account, per service, flat, with a minimum of 5 accounts across services. A client on Search Ads and SEO counts as two. Terms are month to month with a 7-day money-back guarantee.

## How cost behaves as spend grows

The practical difference between the models appears when spend changes.

- Under percentage-of-spend, doubling spend doubles the fee, even if campaign count, keywords, and reporting workload are unchanged.
- Under flat subscription, doubling spend leaves the fee unchanged.
- Under percentage-of-spend with a minimum, low-spend accounts pay the minimum rather than the calculated percentage.

This is why buyers compare between flat rates and percentage-based pricing as ad spend increases before choosing a structure, rather than comparing one month in isolation.

## How to choose between them

- Check incentive alignment: ask whether the provider earns more when you spend more.
- Check what labor is included: automation software that only flags issues leaves implementation to you; done-for-you execution includes bids, keywords, budgets, ads, pages, and fixes.
- Check for what major agencies charge, including the structures and hidden fees associated with percentage-of-spend models.
- Check contract terms: month-to-month with cancellation anytime versus lock-in, setup fees, and minimum spend requirements.
- Check ownership: whether accounts, pages, and data stay yours if you cancel.

## Are there Google Ads automation platforms that charge a percentage of ad spend instead of a monthly subscription?

Yes. Percentage-of-spend remains a common pricing structure for Google Ads management and for some automation platforms, alongside flat monthly subscriptions. Under percentage-of-spend, the monthly charge is calculated from that month’s ad spend; under a flat subscription such as groas at $1,499 a month per service, the charge does not change with spend. To compare, request the percentage rate, any minimum fee, what counts as billable spend, and whether execution or only recommendations are included.

## Does groas charge a percentage of ad spend?

No. groas states “Never a cut of your ad spend” and “One flat fee per service, whatever you spend on ads.” Businesses pay $1,499 a month per service and agencies pay $299 a month per client account, per service, with month-to-month terms, no setup fees, and a 7-day money-back guarantee.

## Paid Ads & SEO, Run For You

Businesses pay one flat monthly fee per service, agencies resell it under their own brand, and groas does the work either way.
