How this agency makes money

Revenue, margin and what an hour of work brings in. Everything on the earning side sits together here.

Revenue trendgross margin per financial year

202120222023

Latest year: € 1,43 mln gross margin, growth +6,9% against a sector median of +15,5%.

Loss-making

Revenue per headGross margin per FTE, against payroll cost

€ 61.439

Median (2023) € 69.371

Against a payroll cost of € 96.874 per FTE. The ratio between the two is the coverage rate above.

Below the median

Yield levelYield per hour worked, against payroll cost

€ 39

Median (2023) € 41

36.475 hours worked, 1.565 per FTE. Against that sits € 62 of payroll cost per hour worked, leaving € -23 for premises, equipment, depreciation and profit.

Around the median

No hourly rate follows from this. Gross margin is already net of services and sundry goods, which mixes rebilled production with the agency's own overhead, and the accounts do not say how many hours were billable. Deriving a rate from this systematically understates it.

2

Can the agency take a hit

Buffer, cash position and payment behaviour side by side, so you can see where they disagree.

Bufferequity in months of payroll

Buffer: -4,5 months (median 7,0 mo). Equity in the latest year: € -846.467.

Critical buffer

Cash positionAvailable cash, and whether it covers short-term debt

Cash -. Liquidity ratio 0,32: current assets cover short-term debt not in full. Solvency -114,6%.

Payment behaviourTowards suppliers and towards the NBB

What this factsheet does not know

How good the work is. Figures do not measure creativity, strategy or chemistry.
How the client portfolio is spread. Concentration is not in the accounts.
Freelancers and subcontractors are not in the FTE figures. An agency with 40 staff may in practice run with 70 people.
The figures cover financial year 2023, filed on 03/06/2024. At a fast-moving agency reality today may differ.

People 7 people mapped

This is first a build crew — 2 of 7 are developers. Within that core, Full Stack and DevOps stand out. The titles skew top-heavy: lots of seniority, few juniors — you're mostly buying experience. A specialist, not a generalist: the expertise is narrow but deep.

Seniors or juniors?

Payroll cost per FTE is the best public proxy for a team's experience level. Higher is not automatically better, but it says something about who sits at the table.

Team composition

Median Social media bureau (2023) € 49.147All agencies (2023) € 57.182

Read with care. Directors and partners invoicing through a management company are not in the payroll cost. At small agencies this skews the picture downwards considerably.

3

Will your team stay?

Inflow and outflow from the social report. This series only counts people on the payroll: freelancers who invoice do not appear in it. A low figure therefore means two very different things, a stable permanent team or a small core with heavy outsourcing. A high figure usually points to short contracts. Compare only within the same type of agency.
