Marketing Investment: Stop Funding Activity, Start Funding Outcomes

Marketing investment is the allocation of financial resources to marketing activities with the expectation of a measurable commercial return. The distinction between investment and spend matters more than most finance directors give it credit for: spend is a cost you tolerate, investment is a commitment you manage. When marketing leaders frame their budgets as the latter, the conversations they have with boards, CFOs, and commercial teams change entirely.

Most marketing budgets are built on precedent, not evidence. Last year’s number, adjusted up or down depending on how the business feels about marketing that quarter. This article is about how to break that cycle and build a case for marketing investment that holds up under commercial scrutiny.

Early in my career, I asked the managing director of the agency I was working at for budget to build a new website. The answer was no. Not “let’s look at the business case.” Just no. I could have accepted it. Instead, I taught myself to code and built it anyway. The experience taught me something I’ve carried for two decades: when the business won’t fund something, the question isn’t whether to give up. It’s whether you can find another way to prove the value first. That instinct, proving value before asking for resource, is at the core of how the best marketing investment decisions get made.

What Makes a Budget a Marketing Investment?

The word “investment” implies three things: intent, expectation, and accountability. You put money in with a specific purpose, you expect a return that can be defined in advance, and you hold someone responsible for delivering it. Most marketing budgets satisfy none of these criteria. They are approved in annual planning cycles, distributed across channels based on habit or internal politics, and evaluated after the fact using metrics that were never tied to commercial outcomes in the first place.

A genuine marketing investment starts with a question: what commercial outcome are we trying to produce, and what is the most efficient way to produce it? That question forces a conversation that most marketing teams avoid because it requires them to commit to something measurable. The principles behind sound marketing budget planning are well-documented, but the execution consistently falls short because the commercial framing is missing from the start.

If you want to go deeper on how marketing investment decisions sit within a broader operational framework, the Marketing Operations hub covers the full picture, from planning and process through to measurement and team structure.

How Do You Set a Marketing Investment Level That Makes Sense?

There is no universal answer, and anyone who tells you otherwise is selling something. The right level of marketing investment depends on your sector, your competitive position, your growth ambitions, your margin structure, and whether you are trying to acquire new customers or retain existing ones. These variables interact in ways that make generic percentage-of-revenue benchmarks almost meaningless in practice.

That said, benchmarks are not useless. They give you a starting point for a conversation. A professional services firm investing 2% of revenue in marketing while its competitors invest 8% should at least understand why that gap exists and whether it is intentional. An architecture firm in a growth phase needs to think about its marketing investment differently from one that is managing a stable, referral-driven client base. The architecture firm marketing budget question is a useful case study in how sector-specific context changes the investment calculus entirely.

The same logic applies to non-profits, where the tension between mission and margin creates a genuinely different investment framework. Spending too little on marketing in the non-profit sector is not virtuous frugality. It is a failure to reach the people the organisation exists to serve. The question of what percentage non-profits should allocate to marketing is one that boards consistently get wrong because they treat it as a cost question rather than an impact question.

When I was running iProspect, we grew the team from around 20 people to over 100. That kind of growth does not happen without commercial discipline in how you think about investment, both the investment clients make in their marketing and the investment the agency makes in its own capability. I watched businesses in the same sector make wildly different decisions about marketing investment and produce wildly different results. The gap was rarely the channel or the creative. It was whether the investment decision was connected to a commercial goal before the money was committed.

Which Channels Deserve the Most Investment?

This is the question most marketing teams spend the most time on, and it is often the wrong question. Channel allocation is a downstream decision. It should follow from a clear view of where your customers are, what they need to hear, and at what point in the buying process your marketing can most efficiently influence them. When channel allocation drives strategy rather than follows it, you end up with budgets that reflect the confidence of channel specialists rather than the logic of the commercial problem.

I spent a significant part of my career in performance marketing, managing hundreds of millions in paid media spend across 30 industries. One of the things that experience taught me is that most performance marketing is better at capturing demand than creating it. Paid search is enormously efficient at intercepting people who already know what they want. It is much less efficient at building the awareness and preference that creates that demand in the first place. When businesses over-invest in performance channels and under-invest in brand, they are essentially mining a seam that they are simultaneously failing to replenish.

Early in my time at lastminute.com, I ran a paid search campaign for a music festival. The campaign was not complicated. But within roughly a day, it had generated six figures of revenue. That kind of result is seductive. It makes performance marketing look like a magic tap you can turn on whenever you need revenue. The risk is that you start to believe the tap will always work at the same rate, and you stop investing in the brand equity that makes people search in the first place. The marketing process framework matters here because it forces you to think about the full funnel, not just the bottom of it.

For organisations that are thinking about how to run structured sessions to align on channel investment priorities, running a marketing workshop is one of the most effective ways to get internal stakeholders to the same starting point before budget decisions are made.

How Should Smaller Organisations Think About Marketing Investment?

Smaller organisations face a version of the marketing investment problem that is structurally different from large enterprises. They typically cannot afford the full-service agency model. They often do not have the internal headcount to run a properly resourced marketing function. And they are frequently making investment decisions based on what their founder or MD thinks marketing should cost, rather than what it actually needs to cost to move the commercial needle.

The virtual marketing department model has become a genuinely viable answer to this problem. Rather than hiring a full internal team or paying agency retainers that eat into margin, smaller businesses can access senior marketing capability on a flexible basis. The investment case is different but the principle is the same: you are still committing resource with an expectation of commercial return. The structure just changes.

Interior design firms are a good example of a sector where this tension plays out regularly. The principals are often exceptional at their craft and uncomfortable with the commercial side of marketing. They under-invest in marketing during busy periods because they do not need new clients, and then scramble to invest when the pipeline dries up. A properly structured interior design firm marketing plan treats investment as a consistent commitment rather than a reactive measure, which changes the economics of client acquisition significantly over time.

The principles of outsourcing marketing operations effectively are worth understanding for any organisation that is trying to access capability without building a full internal function. The quality of the brief and the clarity of the commercial objective matter more than the structure of the engagement.

What Does Good Marketing Investment Measurement Look Like?

Measurement is where marketing investment decisions either get validated or quietly abandoned. Most marketing teams measure what is easy to measure rather than what matters. Click-through rates, impressions, social engagement: these are activity metrics. They tell you whether something happened. They do not tell you whether the investment produced a commercial return.

The measurement framework needs to be agreed before the investment is made, not after. This sounds obvious. It is almost universally ignored. When I was judging the Effie Awards, one of the things that separated the entries that won from the ones that did not was the quality of the commercial objective that had been set at the start. The winning cases had a clear before-and-after: here is what the business needed, here is what we invested, here is what changed. The unsuccessful entries had activity metrics dressed up as outcomes.

The honest version of marketing measurement acknowledges that attribution is imperfect. You will rarely be able to draw a clean line from a specific marketing investment to a specific commercial result. What you can do is build a framework that gives you honest approximation rather than false precision. Understanding how marketing teams use behavioural data to build a clearer picture of what is actually driving results is part of that process. So is being willing to say that some of your investment is working in ways you cannot directly measure, and being honest about that rather than pretending the attribution model captures everything.

Privacy changes have complicated this further. The shift away from third-party cookies and the tightening of data regulations have reduced the resolution of digital attribution models significantly. Organisations that built their measurement frameworks entirely on cookie-based tracking are now flying with less visibility than they had five years ago. The implications of GDPR and data privacy for marketing measurement are not going away, and investment decisions need to account for that reduced visibility rather than pretending the old models still work.

How Do Regulated Sectors Approach Marketing Investment Differently?

Regulated sectors add a layer of complexity to marketing investment that most general frameworks ignore. Financial services, healthcare, and similarly regulated industries face constraints on what they can say, how they can say it, and which channels they can use. These constraints change the investment calculus in ways that matter.

Credit unions are a useful example. They operate in a competitive financial services market, often against banks with significantly larger marketing budgets, but they carry constraints around membership eligibility, regulatory language, and community trust that shape what effective marketing investment looks like. A credit union marketing plan that ignores those constraints and simply tries to outspend the competition will fail. One that builds investment around the genuine differentiators of the credit union model, member ownership, community focus, and transparent pricing, can compete effectively at a fraction of the budget.

The broader point is that marketing investment decisions in regulated sectors need to account for compliance costs, approval processes, and the reputational risk of getting the message wrong. These are real costs that belong in the investment calculation, not afterthoughts.

What Are the Most Common Marketing Investment Mistakes?

After two decades of running agencies, managing client budgets, and watching businesses make decisions about marketing investment from the inside, the mistakes cluster into a small number of patterns.

The first is treating the marketing budget as a fixed percentage of last year’s revenue with no connection to what the business is trying to achieve this year. If you are entering a new market, defending market share, or launching a new product, the investment logic is different in each case. A single percentage figure cannot capture that.

The second is concentrating investment in channels that are easy to measure at the expense of channels that are hard to measure but commercially important. Brand investment is the most common casualty. Because it is difficult to attribute brand spend to specific revenue outcomes, it gets cut first when budgets are under pressure. The result is a business that is increasingly efficient at capturing existing demand while slowly depleting the brand equity that generates that demand.

The third is failing to invest in the data and measurement infrastructure that would allow better investment decisions in the future. Integrated data strategy for marketing organisations is not a nice-to-have. It is the foundation on which every future investment decision rests. Businesses that treat it as a technology cost rather than a marketing investment consistently make worse decisions with larger budgets than businesses that invest in the infrastructure first.

The fourth is making investment decisions in isolation from the rest of the business. Marketing investment that is not connected to sales capacity, product readiness, and operational capability will underperform regardless of how well the marketing itself is executed. I have seen businesses pour significant budget into demand generation campaigns while their sales team was at half capacity. The leads came in and went nowhere. The marketing looked like it failed. It did not fail. The investment decision failed because it was made without reference to the commercial system it was supposed to feed.

The inbound marketing process is a useful reminder that marketing investment works as a system, not as a collection of individual channel decisions. Every element needs to be funded and functioning for the investment to produce its intended return.

There is a broader body of thinking on how to structure marketing operations to support better investment decisions across the full range of business contexts. The Marketing Operations section of The Marketing Juice covers this in depth, from how to build planning processes that connect marketing to commercial goals through to how to structure teams and measurement frameworks that hold up under scrutiny.
