Many SME CEOs eventually reach the same uncomfortable moment.
They review their marketing spend and ask a familiar question:
“How did we end up spending this much… for so little impact?”
They realise the cost has grown steadily while the commercial contribution still feels light. Activity is high. Confidence is low.
What usually follows is a round of cost cutting. Suppliers are dropped. Roles are trimmed. Activity stalls.
Then, slowly, over time, the costs creep back in again. Different people. Different agencies. New ideas. Same outcome.
This cycle is surprisingly common, and it’s bad for the business. It damages momentum, it’s not good for morale, and it’s definitely not good for marketing results.
So how does it happen? This article looks at what causes marketing costs to escalate and how to prevent it.
How marketing cost creep really happens
Marketing cost problems rarely begin with a single reckless decision.
They begin with uncertainty.
In most SMEs, leadership teams don’t have clear reference points for marketing investment. They don’t know:
- What a business like theirs typically spends at their size and stage
- What “good” looks like for cost per lead or acquisition in their category
- What over- or under-resourced actually means in practical terms
Without those anchors, every decision is made in a vacuum.
On top of that, marketing often feels more discretionary than other functions. Sales, operations, and finance are seen as unavoidable costs of doing business. Marketing still feels optional; something you add when profit allows, rather than design to create profit.
Finally, there’s the confusion of the marketing landscape itself. Marketing is noisy. Full of trends, tools, tactics, and strong opinions. For leaders without a marketing background, confidence in where to invest is hard to come by.
Uncertainty leads to caution.
Caution leads to compromise.
The rise of small bets
When confidence is low, businesses often default to small bets.
Investment decisions are broken down into smaller pieces, budgets are released incrementally in ways that feel manageable and low risk:
- A single marketing hire instead of a properly designed team
- One channel test instead of a system that compounds
- A new supplier bolted on to “fix” a specific problem
- £500 here, £1,000 there, £3,000 on something else
Each decision makes sense on its own. But over time, these small bets accumulate.
You end up with layers of people, partners, and activity, without a unifying strategy or delivery model. Costs rise quietly, complexity increases, and marketing becomes busy rather than effective.
Ironically, this approach often costs more than making a few deliberate, well-structured investments upfront, while delivering far less commercial impact.
Small bets vs big bets
The pattern I’ve just described reflects an investment mindset rather than a cost control or spending issue.
Small bets prioritise comfort and optionality, reducing pressure on individual decisions. They minimise perceived risk, but maximise long-term inefficiency.
Big bets work differently. They require more thought upfront, more clearly defined outcomes, and a longer time horizon. They feel heavier and harder to reverse, but ultimately lay the foundations for sustainable, profitable growth.
Think about it this way:
- You wouldn’t buy a house floor by floor and expect it to work as a family home
- You wouldn’t build a car one part at a time and expect it to get you from A to B
Yet this is exactly how many SMEs build their marketing functions.
People work around capability gaps rather than resolving them. Suppliers overlap or duplicate effort. Channels compete for attention rather than reinforcing each other. Strategy becomes implicit rather than explicit.
Costs rise quietly because no single decision feels excessive. Impact remains inconsistent because the sum of the parts aren’t greater than the whole.
The way out: outside-in planning
A different outcome requires a different starting point.
Breaking the cycle requires planning better. Specifically, planning outside-in.
This means establishing reference points before committing resources, grounding decisions in evidence beyond your own four walls:
- How much do comparable businesses invest at this stage?
- What level of capability does it take to outperform competitors in this category?
- Which channels genuinely deliver ROI in this market?
- What skills are essential to execute those channels properly?
- What does it realistically cost to compete effectively in this space?
- Given the buying cycle in this category, how long should we expect before returns show up?
With answers to these questions, decisions become clearer and investment stops being guesswork.
Investment shifts from incremental to intentional.
Priorities narrow.
Bets get fewer, but bigger.
Fewer decisions. Higher standards.
High performing marketing functions make fewer decisions with greater clarity.
They commit to defined plans.They resource those plans properly.They allow sufficient time for results to emerge.When that happens, costs stop spiralling and confidence improves. Contribution becomes easier to see because it is tied to a clear plan rather than a collection of activities.
That is how marketing spend in a P&L moves from a difficult expense to a growth function the business depends on.
