The answer follows the arithmetic. Below roughly R10,000 a month in ad spend, a management fee is a large share of your total budget and self-managing usually wins. Above roughly R15,000, a single management mistake costs more than the fee.

The arithmetic

Monthly ad spend	Management at R6,000	Sensible route
R5,000	120% of spend	Do it yourself
R10,000	60% of spend	Yourself, or a setup-only engagement
R15,000	40% of spend	Borderline
R25,000	24% of spend	Agency
R50,000+	12% of spend	Agency

All figures exclude VAT. Advertising spend is billed separately by the platform and is never marked up by Juicy Designs.

At R5,000 of spend, paying R6,000 to manage it means R11,000 buying R5,000 of advertising. Even a very good agency struggles to justify that. The exception is a one-off setup engagement, which is a better use of the same money.

What self-managing actually involves

Setup: four to eight hours, done properly. Conversion tracking, keyword research, negatives, ad copy, landing page alignment, geography and campaign settings.

Ongoing: two to four hours a month. Search terms report weekly, negatives, pausing non-performers, testing ad copy, checking cost per lead.

Learning: 20 to 40 hours across the first few months, and this is the part people underestimate. The mechanics are learnable from Google's own documentation; developing judgement about what a change will do takes repetition.

Two to four hours a month is genuinely achievable for a business owner. The failure mode is not the hours, it is consistency: accounts that get attention in month one and none in months two and three drift badly.

What you are actually buying from an agency

Not the mechanics. Anyone can add negative keywords.

Pattern recognition. Someone who has watched fifty accounts through a seasonal shift knows whether a rising cost per click is a competitor, a quality score decline or a normal December. That takes years to acquire and a phone call to use.

Avoiding expensive mistakes. Broad match on a small budget, Display left on in a Search campaign, Performance Max as a first campaign, bidding changes that reset the learning phase weekly. Each of those can cost more in a month than a management fee.

Being told to stop. A good agency will say when your landing page is the problem, or when your budget is too small to compete, or when the money would do more elsewhere. That advice is worth something and it is hard to give yourself.

The middle option most people miss

Pay for a proper setup, then run it yourself.

A once-off build covering conversion tracking, keyword research, campaign structure, negatives, ad copy and landing page guidance typically runs R8,000 to R15,000. You then maintain it, with the structure right from the start.

This suits businesses spending R5,000 to R12,000 a month better than either extreme, and it is rarely offered because ongoing management is the more profitable product to sell.

Signs you should hand it over

Your cost per lead has been rising for three months and you cannot say why. You have not opened the search terms report in a month. Your spend has grown past R15,000 and the account still has the structure it launched with. Or you keep making changes and cannot tell which one caused what.

That last one is the clearest signal. An account being adjusted without a hypothesis is being made worse.

If you hire, insist on these

The account in your name with the agency added as a user, so you can leave with your history. Ad spend billed to you directly by Google, never marked up. Month-to-month, because a lock-in removes your only leverage. And reporting on cost per lead rather than impressions and clicks.

Juicy Designs offers both setup-only and ongoing management from R6,000 per month, month-to-month, account always in your name. See Google Ads management. Related: percentage vs flat fee and your first campaign.

Frequently asked questions

Should I manage Google Ads myself or hire an agency?

Manage it yourself below about R10,000 a month in ad spend, where a management fee would be a large share of the total. Hire above roughly R15,000, where a management error costs more than the fee. Between the two it depends on how much your own time is worth.

How many hours does managing it myself take?

Four to eight hours to set up properly, then two to four hours a month to maintain: search terms, negatives, ad testing and reporting. The learning curve is another 20 to 40 hours spread over the first few months.

What does agency management cost in South Africa?

From about R6,000 per month, or 10% to 20% of ad spend on percentage models. Ad spend should be billed to you directly by Google and never marked up.

What does an agency actually do that I cannot?

Recognise patterns from having watched many accounts through the same conditions, judge when a rising cost per click is worth paying, and avoid the expensive mistakes. The mechanics are learnable; the judgement takes repetition.

Can I start myself and hire later?

Yes, and it is a sensible order. Running it yourself for three months teaches you enough to judge an agency properly, and the account history transfers with you.
