How Much Should My Firm Spend on Business Development?

Budget roughly 5–6% of net service revenue for marketing and business development — and expect most of it to be staff time, not media spend. NSPE benchmarks put AEC firms at about one BD professional per 35 staff, with total spend (including labor) landing in that 5–6% range. PSMJ's research narrows it slightly, at 3.1–5.3% of net service revenue, but finds that firms with a dedicated "center of excellence" for BD invest around 3.9% of NSR while reporting 22% revenue growth — spending less than average and growing faster.

What does the typical AEC marketing budget actually cover?

Mostly people, not campaigns. NSPE's benchmark of roughly one BD professional per 35 staff means the 5–6% of net service revenue figure is dominated by salaries — proposal writers, marketing coordinators, principal time spent on pursuits — not advertising or paid content. If your "marketing budget" line only counts a website and some print collateral, you're almost certainly undercounting the real spend, since the biggest cost is time your team is already spending on pursuits.

Why do top-performing firms spend less and grow faster?

Because the return comes from focus, not volume. PSMJ's research found that firms with a dedicated BD center of excellence — a defined function and process, not just ad hoc effort — spent around 3.9% of NSR, below the broader 3.1–5.3% range, while reporting 22% revenue growth. The lesson isn't "spend less" in isolation; it's that a structured, accountable BD function outperforms diffuse effort even at a lower cost.

Where should a small firm reallocate first if the budget is tight?

Before cutting spend, look at where the current 5–6% is going. If it's concentrated in production time — proposal writing, formatting, chasing down qualifications material — that's the same waste this blog covers in how long a proposal takes to write. Reallocating hours from rebuilding proposals to qualifying pursuits and nurturing relationships costs nothing extra and moves the same budget toward higher-return activity.
