The honest answer to "what does performance marketing cost" is that it is three separate costs, and most quotes only make one of them obvious. Understanding the split is what stops you comparing an agency charging R6,000 a month against one charging R15,000 and assuming the cheaper one is better value.
Key takeaways
- Your total cost is ad spend plus management fee plus tooling. Ad spend is usually the largest of the three and the one you control directly.
- Below roughly R8,000 to R10,000 a month in ad spend, most accounts cannot gather enough conversion data to optimise properly.
- Pay the platforms directly from your own billing account. The agency should invoice its fee separately.
- Judge cost per acquisition, not cost per click. A cheaper click that never converts is the more expensive option.
The three costs, separated
Ad spend. The money that goes to Google, Meta, TikTok or LinkedIn. This is not an agency fee. It should be paid from a billing account in your name, and you should be able to log in and see exactly what was spent. Google documents its own billing and payment settings publicly, so there is no reason for this to be opaque.
Management fee. What you pay a person or agency to plan, build, run and improve the campaigns. This covers keyword and audience research, ad and landing page creation, bid strategy, testing, and reporting.
Tooling and tracking. Analytics, call tracking, heatmaps, a CRM connection, sometimes a landing page tool. Often small, occasionally significant, and frequently left off a quote entirely.
How management fees are structured
Percentage of ad spend
Scales with budget
Best for
Larger accounts with substantial and stable monthly spend
- Fee rises automatically as spend rises
- Simple to understand
- Creates an incentive to recommend spending more
Flat monthly retainer
Predictable
Best for
Small and mid-sized businesses that need budget certainty
- Same cost every month regardless of spend
- Easy to forecast
- Fee is unaffected if you pause campaigns
Hybrid
Base plus performance
Best for
Businesses with clean tracking and a clearly defined conversion
- Lower base fee
- Upside tied to an agreed outcome
- Only works when attribution is genuinely trustworthy
None of these is inherently better. What matters is that you know which one you are on, and what happens to the fee in a slow month. Ask that question directly before signing.
The minimum worth starting with
This is the question behind the question, and most agencies avoid answering it because the honest answer sometimes loses them a client.
Paid platforms need conversion data to optimise. Modern bidding is largely automated, and automation needs volume to learn from. Starve it and the campaign sits in a permanent learning phase, spending money without ever getting better. This is also why the quality of the page you send traffic to matters as much as the campaign itself, something we cover in our website development guide.
As a working guideline, below roughly R8,000 to R10,000 a month in ad spend it becomes hard to generate enough conversions for that learning to happen within a sensible timeframe. That is a guideline, not a law. A high-value B2B service with a narrow keyword set and a R60,000 deal size can work on less. A competitive consumer category with a R400 basket will need considerably more.
Why cost per click is the wrong number to shop on
Two accounts in the same industry can have wildly different costs per click and identical costs per customer. Click price is an input. What you actually care about is what it costs to acquire a paying customer, and whether that figure is comfortably below what that customer is worth to you.
The number that decides whether paid marketing is working
A cheaper click that lands on a slow, unconvincing page is the more expensive option, because you pay for the click either way and get nothing for it. Page speed is part of this: Google's own Core Web Vitals thresholds exist because slow pages lose people before they convert.
This is why conversion work is not a nice-to-have bolted on afterwards. Improving the rate at which visitors convert lowers your acquisition cost without spending a cent more on media. Our performance marketing service treats the two as one job for that reason.
What to check before you sign
- Ad spend and management fee are itemised separately
- The ad accounts are registered in your business name, and you have admin access
- Conversion tracking is set up and verified before spend starts, not after
- Reporting shows cost per acquisition and revenue, not just impressions and clicks
- You know the notice period and what happens to the accounts if you leave
That second point is the one people regret ignoring. If the agency owns the ad account, you lose the entire conversion history when you part ways, and the next team starts from zero.
If you are still deciding whether paid media is even the right lever to pull, what digital strategy actually is walks through how to find the constraint before you spend against it.
