How is a marketing agency valued?

The multiple gets all the attention. What most owners underestimate is how much of the final number is decided by how the books were kept in the two years before anyone made an offer.

What multiple do marketing agencies sell for?

These are broad market ranges and any individual deal can sit outside them. Smaller agencies — under roughly $1M of EBITDA — tend to trade toward the lower end regardless of profile, simply because the buyer pool is thinner and the concentration risk is higher.

What actually moves the multiple

Four things, in roughly this order of impact.

Revenue quality

Contracted, recurring revenue is worth substantially more than the same dollars won project by project. A buyer underwriting a retainer base is buying something they can forecast; a buyer looking at project revenue is buying your ability to keep selling, which they may not be able to replicate.

Client concentration

The single fastest way to lose turns. An agency where one client is 40% of revenue carries a risk the buyer has to price, and they will price it conservatively. Below roughly 15–20% for the largest client is comfortable; above 30% expects questions and a discount, or an earnout structured around that account staying.

Margin, and whether it is real

Buyers examine whether margin comes from pricing discipline or from underpaying people who will leave after the sale. A 25% net margin achieved by not replacing three departed staff is not a 25% margin, and diligence finds it.

Founder dependence

If you hold the client relationships, the pitching and the quality bar, the buyer is acquiring a job rather than a business. This is usually the difference between a strategic price and an earnout that pays out only if you stay three years.

The accounting decisions that change the number

Everything above is about the multiple. This section is about the number it multiplies — and it is where agencies quietly give away value.

Gross versus net revenue

The single largest one. If you report client media spend as revenue, your reported EBITDA margin collapses and your business reads as a low-margin reseller.

Identical business, identical profit. One version looks like a business with structural margin problems; the other looks healthy. Sophisticated buyers restate this themselves, but you will have spent the process arguing about your own numbers from a weaker position — and less sophisticated buyers simply pass. The full explanation of gross versus net is here.

Revenue recognition on retainers

An agency recognising a twelve-month retainer in the month it invoices produces a revenue line that swings for no operational reason. A buyer sees either sloppiness or an attempt to flatter a period, and both invite a closer look at everything else. A deferred revenue schedule is a few minutes a month and removes the question entirely.

Add-backs you cannot evidence

Owner salary above market, personal expenses run through the business, one-off legal costs — all legitimately added back to arrive at adjusted EBITDA, but only if you can evidence them line by line. Add-backs a buyer cannot verify get struck out, and each struck-out dollar costs you the full multiple.

Client-level profitability

Increasingly asked for in diligence, and most agencies cannot produce it. Being able to hand over margin by client demonstrates control and lets you defend the accounts a buyer is nervous about. Not being able to produce it invites the assumption that you do not know.

What buyers ask for in diligence

Broadly the same list every time. The agencies that come out well are the ones for whom this is a download rather than a project.

• Three years of financial statements, with revenue clearly stated net of pass-through
• Revenue by client by month, ideally three years
• Client contracts, with notice periods and any change-of-control clauses
• The deferred revenue schedule and its reconciliation to the balance sheet
• Delivery cost by client, or the hours data to derive it
• Staff list with roles, salaries, start dates and contractor arrangements
• Add-back schedule with supporting evidence for every line
• Aged receivables and any bad debt history

The pattern to notice: almost every item depends on the books having been structured properly all along. None of it can be assembled retrospectively without a great deal of work, and doing it under deal pressure is where mistakes and discounts happen.

If you might sell in the next two years

1. Restate revenue net of pass-through now. Not at the point of sale. You want two clean comparable years, which means starting at least two years before you plan to run a process.
2. Get the deferred revenue schedule running monthly. Cheap, fast, and it removes a whole category of question.
3. Reduce client concentration deliberately. It is the fastest single improvement to the multiple and the slowest to execute, which is why it has to start early.
4. Build the margin-by-client report and keep the history. Two years of it is a genuinely differentiating artifact in diligence.
5. Document add-backs as they happen, with evidence attached, rather than reconstructing them from memory in a data room.
6. Move yourself out of delivery and out of the client relationships. The hardest item and the one with the largest effect on whether you get paid at close or over three years.

None of this is a sale tactic. It is the same work that makes the agency easier to run in the meantime, which is what makes it worth doing whether or not you ever sell.
