A direct question to start. What was your agency’s gross margin last month?
If you know the number to within a point or two, you’re in the top twenty percent of agency founders I talk to. If you’re guessing, or if you’re thinking “I track net profit, isn’t that the same thing,” you’re in the group whose valuation multiple is about to come in lower than expected.
Tracking gross margin weekly, not just monthly or quarterly, was one of the biggest shifts in how I ran my agency. Within six months of that discipline, we had moved net profit from 11% to 17%. Same clients. Same pricing. What changed was visibility.
This article is about why that visibility matters, and the specific numbers any agency founder should be tracking.
The difference in plain English
Gross margin = revenue minus the direct cost of delivering the work.
Net margin = revenue minus all costs (direct delivery plus overheads, admin, premises, owner salary, everything).
If you bill £100,000 in a month and it cost you £55,000 in team time and subcontractors to deliver that work, your gross margin is £45,000, or 45%.
If you then pay £30,000 in overheads (rent, software, admin, pension, all the fixed costs), your net margin is £15,000, or 15%.
Gross margin tells you whether your pricing and delivery are working. Net margin tells you whether your overall business is profitable.
Buyers care about both. They care about gross margin first.
Why gross margin tells buyers more than net margin
Net margin is easy to manipulate. You can cut overheads, defer hiring, underpay the founder, run lean on benefits. Net margin improves. Nothing fundamental has changed about the business.
Gross margin is harder to fake. Gross margin tells you whether the work you’re selling is actually profitable to deliver at the price you’re charging. It’s the truest measure of whether your pricing is right and your delivery is efficient.
When buyers look at an agency:
- Gross margin under 45%: Suggests underpricing, scope creep, inefficient delivery, or team costs out of line with revenue. Buyer flag.
- Gross margin 45-55%: Typical for agencies running well. Nothing special.
- Gross margin 55-65%: Strong pricing discipline, efficient delivery, good return on team time. Premium signal.
- Gross margin above 65%: Very strong, usually productised or specialist services. Highest premium.
The gross margin number tells buyers what’s possible. Net margin tells them what you’re currently extracting. Both matter. Gross margin is the leading indicator.
The gross margin calculation buyers actually use
Here’s the maths.
Direct costs include:
- Salaries of anyone who delivers work (designers, developers, account teams, strategists)
- A proportion of benefits, pension, employer NI for those people
- Freelancers, subcontractors, and specialist suppliers
- Direct tools used in delivery (software licences, stock assets)
Direct costs exclude:
- Sales and marketing team salaries
- Admin team salaries
- Owner salary (if the owner is not delivering client work)
- Rent, utilities, office costs
- General tools (accounting, HR, meeting software)
- Training, professional development, benefits overhead
The split you are drawing is between costs that scale with client work (direct) and costs that run regardless (overhead).

What moves gross margin up
Four levers in my experience.
Lever 1: Pricing discipline
The single biggest driver of gross margin is whether you’re charging the right price for the work. Under-pricing is the default state for agencies, especially founder-led ones. You know what it costs to deliver (you did it yourself for years). You know what you’d pay. You struggle to charge more than that.
The fix is benchmarking. What do clients pay for equivalent work from agencies of your size? Usually 20-40% more than you’re charging. Close that gap and gross margin follows.
Don’t do this by putting new prices on old work. Do it on new clients first, then gradually migrate existing ones to new pricing at renewal points.
Lever 2: Team cost-to-revenue ratio
The second lever is whether your team cost structure matches the revenue each person generates. The rule of thumb for healthy creative agencies is that salary cost (the direct delivery team) should be 30-45% of revenue. If you’re over 50%, you have a structural problem.
The tool I use for this is Revenue Per Seat. Every team member should generate 3-5x their salary cost in billed revenue. 3x is baseline. 5x is gold medal. Anyone under 2.5x is a structural drag on gross margin.
A client of mine had a 72% salary-to-revenue ratio at a £900K agency. After 12 months of deliberate hiring, repricing, and one difficult conversation about a long-tenure underperformer, the ratio came down to 46%. Gross margin went from 28% to 54%. Net profit went from breakeven to 18%.
Lever 3: Scope management
The third lever is whether you deliver what you quoted, or whether you deliver that plus another 30% of unpaid work because “it’ll only take an hour.”
Scope creep kills gross margin silently. Every hour of unquoted work is an hour of uncharged delivery cost hitting your margin. If your teams are running 30% over scope on most projects, your gross margin is 30% lower than the quote suggested.
The fix is tight scoping at point of sale, change orders for anything outside scope, and monthly scope audits per project. It’s boring. It’s also where the margin lives.
Lever 4: Productisation
The fourth lever is moving from custom work to productised offerings. Custom work has volatile margin (each project is different). Productised offerings have repeatable margin (you’ve built it once, you deliver it many times).
For more on productisation as a margin lever, see the productised services for agencies article (coming shortly in the cluster).
What moves net margin up (once gross margin is healthy)
Once your gross margin is sitting above 50%, net margin becomes about overhead discipline. Three things to look at:
One: headcount in non-delivery roles. Sales, admin, marketing. These don’t scale with client work. Keep them lean. One excellent senior operator beats three mid-level ones for operational efficiency.
Two: software sprawl. Agencies over £500K typically spend £2K-£5K a month on software, half of which is redundant. An annual software audit can release £10K-£25K per year.
Three: office and property costs. Post-2020, many agencies carry property costs that don’t match their new operating model. Review lease commitments against actual usage.
Net margin reflects operational discipline. It matters, but it’s secondary to gross margin for two reasons: buyers see through artificial net margin, and net margin follows gross margin most of the time.
The monthly discipline
Here’s what every agency over £500K in revenue should be doing, weekly or at worst monthly:
Gross margin by project, not just at business level. Every project should have a target gross margin (usually 50-60%). Every project should be measured against it at close. Underperformers reveal either pricing issues or delivery issues. Over time you spot patterns.
Utilisation rates per team member. How much of their paid time is billable? Target 65-75% for delivery roles (not 100%, that’s a burnout metric).
Monthly management accounts. Gross margin, net margin, revenue, pipeline. On one page. Reviewed by the leadership team together.
This is the substance of the Agency KPIs article (coming next in the cluster). If you’re not tracking these yet, that’s the first piece of work.
Where this connects to valuation
Remember the valuation equation from how to value a creative agency: EBITDA × multiple.
Gross margin discipline improves EBITDA (because you’re delivering more profitably). Gross margin discipline also improves the multiple (because buyers see a business that has pricing power and operational control, which commands more confidence in future performance).
A £2M agency with 35% gross margin and 8% EBITDA trades at 3x EBITDA = £480K. The same agency 18 months later at 55% gross margin and 17% EBITDA trades at 5x = £1.7M.
The revenue didn’t move. The gross margin discipline did. That’s £1.2M of additional enterprise value from one operational discipline.
Where to start this quarter
One. Calculate your current gross margin. If you don’t know it, that’s the first piece of work. Last three months, revenue minus direct delivery cost. What’s the percentage?
Two. Check your salary-to-revenue ratio on direct delivery team. Above 50% is a warning. Above 60% is urgent.
Three. Pick your biggest current project and honestly assess: did we deliver to scope, or did we over-deliver by 20-30%? If the latter, that’s the pattern hurting your margin the most.
If you want a full benchmark across the eight value levers buyers price (profitability, recurring revenue, owner independence, concentration, delivery systems, leadership, sales engine, reporting), the free Agency Valuation Calculator is a ten-minute tool.
If you want monthly advisory support holding you accountable to moving these numbers, the Scale programme runs at £1,000-1,500 a month. Monthly strategy calls, rolling commitment.
If you’re ready to do the full operational transformation (all eight value levers in sequence), the Strategic Growth Programme is the seven-month programme for that. £18,000, 1:1, structured.
Gross margin is boring. Gross margin is also where the real commercial power of an agency lives. Start tracking it and everything else gets easier.
