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 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.
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.
Search Ads 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:
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.
The practical difference between the models appears when spend changes.
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.
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.
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.
