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

20212022202320242025

Latest year: € 1,63 mln gross margin, growth -1,7% against a sector median of +0,4%.

ElixirSector median

EBITDA margin 9%, sector median 20,8%. Value-added coverage 1,10 (median 1,12). Value-added coverage sits in the sector-wide grey zone (0.95-1.15): context, not an alarm.

Below sector level

Revenue per headGross margin per FTE, against payroll cost

Median (2025) € 86.163

Against a payroll cost of € 72.202 per FTE. The ratio between the two is the coverage rate above.

Around the median

Yield levelYield per hour worked, against payroll cost

€ 48

Median (2025) € 59

33.809 hours worked, 1.665 per FTE. Against that sits € 43 of payroll cost per hour worked, leaving € 5 for premises, equipment, depreciation and profit.

Below 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.

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: 21,2 months (median 7,2 mo). Equity in the latest year: € 2,59 mln.

Adequate buffer

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

Cash € 202.099. Liquidity ratio 4,11: current assets cover short-term debt in full. Solvency 76,9%.

Amply covered

Payment behaviourTowards suppliers and towards the NBB

Trade payables correspond to 79 days of supplier credit, sector median 73. The accounts were filed 287 days after closing; the legal deadline is seven months.

The annual accounts were filed after the statutory deadline. Over a third of the sector does this, usually because of the accountant's calendar. Rarely a story in itself.

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 2025, filed on 14/10/2026. At a fast-moving agency reality today may differ.

Based on publicly filed annual accounts (NBB) and official records (CBE, Belgian Official Gazette). An indication, not financial advice. Sector medians calculated on 2 Nov 2026. Sector medians based on financial year 2025: the last year for which nearly all accounts have been filed.

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.

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.

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.
