How Much to Spend on Marketing: Professional Services

How much should professional services firms spend on marketing? Most partners answer this question with a number pulled from last year's budget, adjusted slightly for inflation. Almost none of them answer it by looking at what firms actually growing at scale spend.

That gap, between habit and benchmark, is bigger than most leadership teams realize, and it is quietly the reason a lot of growth plans stall before they start.

ALTA Consulting's clinical research across twenty technical firms found a pattern that repeats with striking consistency: the firms struggling to grow are underspending on marketing by more than half, and most of them don't know it.

What is a healthy marketing budget benchmark for professional services firms?

A marketing budget benchmark is a reference point, usually expressed as a percentage of revenue, that shows what firms at different growth rates typically invest in marketing. For technical professional services firms, the most cited reference is the Hinge Research Institute's High Growth Study, which tracks marketing investment across hundreds of firms every year. It consistently finds that firms growing fastest spend meaningfully more on marketing than firms that are stalling, and the gap between the two groups is not small.

How much should professional services firms spend on marketing?

Here is the benchmark that matters. Hinge's research finds that high-growth firms, defined as those achieving 20 percent compound annual growth or more, spend a median of 10 percent of revenue on marketing. Low-growth firms spend a median of 6 percent. That gap alone should give any partner pause.

Now compare that to what ALTA actually found inside its sample. Across twenty technical firms studied, fourteen of twenty, or 70 percent, were spending between 1 and 2 percent of revenue on marketing at the start of their engagement. Eighteen of twenty firms sat below the low-growth benchmark entirely. Only two firms in the whole sample were investing anywhere near the high-growth number.

Put plainly, most of the firms in this study were spending less than a third of what the slower-growing firms in Hinge's research spend, let alone the high-growth cohort. If you are a partner or principal wondering whether your firm's marketing line item is too thin, the odds are good that it is, and by a wider margin than you'd guess.

Why do most technical firms underspend on marketing?

If the case for investing more is this clear, why does the underspend persist across firm after firm? Three reasons show up again and again in ALTA's engagement work, and none of them are about firms being careless.

The attribution problem. A consultant's or engineer's hours bill against a specific project, and the revenue traces directly back to them. Marketing investment doesn't work that way. A research publication, a content program, or a conference presence takes 18 to 36 months to show up in closed revenue, and it touches multiple people along the way. In a culture built around direct attribution, that lag makes marketing spend feel speculative in a way that billable work never does, even when the long-term return is stronger.

No one owns the case for it. Most partners in technical firms came up through delivery, not marketing. They don't have an intuitive sense of what a marketing investment should produce, so the conversation about spend tends to get resolved by referencing last year's number rather than by evaluating what the investment would actually generate. Marketing gets treated as overhead to minimize, not production to fund.

The visible alternative wins. When growth stalls, hiring a person feels concrete. A salesperson has a name, a quota, and a calendar full of meetings you can watch fill up. A marketing investment, by comparison, produces effects you can't point to on a Tuesday afternoon. Faced with that choice, firms consistently reach for the visible option. We've written separately about what that choice actually costs when it happens before the firm is ready, in The Seller-Doer Question, where hiring ahead of the marketing engine was the single most common failure mode ALTA's research identified.

These three forces compound. With no inbound engine, every bit of new business falls to founders and partners who are also responsible for delivery, and billable pressure wins that fight more often than not. The pipeline goes quiet, growth plateaus, and the firm reaches for a sales hire to fix a problem that started upstream.

Old approach vs. the marketing-first approach

The habit-driven approach	The marketing-first approach
Marketing budget set by last year's number	Budget set against the 8-10% high-growth benchmark
Marketing treated as overhead to minimize	Marketing treated as the prerequisite for every growth lever
Growth plateau addressed by hiring a salesperson	Growth plateau addressed by building the pipeline first
Origination falls entirely on founders and partners	Inbound activity reduces founder dependency over time
Content and IP are occasional, reactive	Content and IP are a recurring, resourced function

What does an 8 to 10 percent marketing budget actually fund?

Moving toward the high-growth benchmark isn't about spending more on the same activities. It's about resourcing the specific levers that produce inbound pipeline in a buying environment where most evaluation now happens before a buyer ever contacts a vendor.

That typically includes:

• Content engineered for how a buying committee actually researches, not generic blog output

• Original research and intellectual property published under the firm's own name

• A sustained presence at the conferences and events where the firm's defensible expertise gets seen

• Ongoing curation of the firm's digital presence, since that is the surface buyers encounter before any sales conversation starts

None of this is a one-time project. The firms in ALTA's sample that got this right treated marketing as a system to build and sustain, not a campaign to run once and revisit next budget cycle. Firms weighing where to start often benefit from an outside read on which of these levers matters most for their specific stage, which is where marketing consulting or a fractional marketing engagement tends to fit, particularly for firms not yet ready to build an in-house function at full scale.

The sequence matters more than the number

Here's the part most firms miss. Hitting 8 to 10 percent isn't the finish line, and spending your way to the benchmark doesn't automatically fix a stalled pipeline. What matters is the order in which a firm builds capability, and which investments have to be in place before others make sense. ALTA's research found that firms who hired sales talent before this upstream work was done reproduced the same failure pattern, almost without exception, regardless of firm size or how experienced the seller was.

The full study breaks down exactly where firms typically get this sequence wrong, sorts firms into the patterns that predict success or failure, and shows what separates a marketing investment that compounds from one that just becomes a bigger, equally underperforming line item.

Frequently asked questions

What percentage of revenue should a professional services firm spend on marketing?

High-growth firms spend a median of 10 percent of revenue on marketing, according to Hinge Research Institute's ongoing High Growth Study, compared to a median of 6 percent among low-growth firms. Most technical firms studied by ALTA were spending only 1 to 2 percent, well below even the low-growth benchmark.

Why do technical firms spend so little on marketing compared to the benchmark?

Three forces tend to reinforce underspending: marketing's return takes 18 to 36 months to show up and doesn't attribute cleanly the way billable hours do, most partners came up through delivery and don't have an intuitive feel for marketing investment, and hiring a person feels more concrete than funding a content or IP program. Together these push firms toward habit-based budgets rather than benchmark-based ones.

Is marketing spend or a sales hire the better investment for a stalled pipeline?

In ALTA's research, firms that hired dedicated sales staff before building marketing infrastructure consistently underperformed, regardless of the seller's experience or seniority. Marketing investment functions as the prerequisite that makes a future sales hire productive, not a competing line item to be traded off against it.

Does a small or founder-led firm need to spend at the same rate as a large firm?

The percentage benchmark applies across firm sizes in Hinge's research, though how the budget gets spent differs by stage. Smaller firms typically get more return from building visible expertise and founder-led content than from broad digital lead-generation campaigns, which tend to pay off more once a firm has multiple senior people who can carry client relationships.

How quickly does increased marketing investment show results?

Marketing investment in technical firms typically takes 18 to 36 months to translate into closed revenue, which is part of why it gets underfunded relative to work that shows up on this month's invoice. Firms that stay the course past that lag tend to see inbound pipeline develop into a durable growth lever rather than a short-term spike.

What to do next

If your firm's marketing budget has been set by habit rather than by what actually drives growth, the number to check first is simple: what percentage of revenue are you really investing, and how does it compare to the benchmark. The bigger question, which levers to fund first and in what order, is where most firms get stuck.
