Two agencies, same gross profit, same margin, same team size – and one sells for nearly double the other. The difference isn’t the quality of the work or the calibre of the clients. It’s how the revenue arrives. Buyers don’t pay for what you billed last year; they pay for what they’re confident you’ll bill next year, and most agency owners only discover this when the offer lands lower than they imagined.
This post covers why acquirers pay a premium for recurring revenue, the real multiple gap between retainer-heavy and project-heavy agencies, what buyers actually count as recurring income, and how to shift your revenue mix in the two to three years before you sell.
Why Buyers Pay More for Predictable Revenue
When an acquirer values your agency, they’re not buying your history. They’re buying a stream of future cash flows, and the price they’ll pay is a direct function of how confident they are that those cash flows will materialise.
A project-based agency starts every financial year at zero. However good the team, however strong the reputation, the revenue has to be re-won, month after month. From the buyer’s side of the table, that’s risk – and buyers price risk ruthlessly. Every pound of revenue that has to be hunted rather than harvested gets discounted.
A retainer-based agency starts the year with most of its revenue already contracted. The buyer can look at the client roster, read the agreements, check the renewal history, and model the next three years with reasonable confidence. Less uncertainty means a lower discount, which means a higher multiple on exactly the same profit.
This is why two agencies with identical EBITDA can attract wildly different offers. The numbers on the P&L look the same. The quality of the earnings does not. When I ran my agency, it took me longer than I’d like to admit to internalise this – we celebrated big project wins because they felt like growth, when the retainers quietly doing their job each month were what actually built value.
The valuation conversation, in other words, starts years before the sale process does. It starts with how you structure the next deal you sign.
“You can’t easily double your EBITDA in two years. But you can shift your revenue mix – and let the multiple do the heavy lifting.”
The Multiple Gap: 5-7x Versus 3-4.5x
Here’s the gap in hard numbers. Agencies with 80% or more of their revenue on recurring contracts typically command 5-7x EBITDA at exit. Comparable agencies running predominantly on project work settle for 3-4.5x.
Put that against a real agency. Take a business generating £500K of EBITDA. At the project-heavy end of the range, that’s a valuation of £1.5M-£2.25M. At the retainer-heavy end, the same profit supports £2.5M-£3.5M. Same EBITDA, same effort to build – and a gap of more than £1M in enterprise value, driven by nothing other than revenue mix.
That makes recurring revenue one of the most valuable levers an agency owner controls. You can’t easily double your EBITDA in two years. You can materially shift your revenue mix in that time, and the multiple expansion does the heavy lifting for you.
It’s worth being precise about the threshold, too. Buyers don’t award the premium multiple for “some retainers”. The full effect kicks in when recurring revenue dominates – 80% and above is where an agency stops being valued as a project shop with some contracts and starts being valued as a genuinely predictable business. Between 50% and 80%, you’ll see partial credit. Below 50%, most buyers will treat you as project-based regardless of how you describe yourself.
What Buyers Actually Count as Recurring Revenue
This is where agency owners routinely overestimate their position. Not all repeat revenue is recurring revenue, and buyers apply a much stricter definition than most founders do.
At the top of the hierarchy sit contracted retainers – fixed monthly fees, twelve-month terms or longer, with notice periods and renewal history. This is the gold standard. A buyer can read the contract and bank the revenue.
One rung down: rolling retainers on 30 or 60-day notice. Still recurring, but the short notice period weakens it. A buyer will look hard at tenure – a rolling retainer that’s renewed for four years is worth more than a twelve-month contract signed last quarter.
Then comes repeat project work from long-standing clients. Founders love to present this as “effectively recurring” – the client comes back every year, after all. Buyers don’t accept the framing. There’s no contractual obligation, so it’s relationship revenue, and relationships walk out of the door when founders do. It gets some credit in diligence, but nothing like retainer treatment.
At the bottom: one-off projects from new clients. Pure project revenue, fully discounted, valued only as evidence that your new business engine works.
The practical test a buyer applies is simple: if the founder left tomorrow, which revenue would still arrive next quarter? Be honest about how much of your income survives that question. The signs that your “recurring” revenue won’t hold up in diligence are usually visible well in advance: no signed contracts, fee levels renegotiated every renewal, retainers that flex monthly with scope, and client relationships held exclusively by the founder.
How to Shift Your Mix Without Losing Clients
The good news: moving from project to retainer revenue is a sales and packaging problem, not a service problem. Most agencies already do work that clients need continuously – they just sell it in lumps.
Start with your existing clients, because that’s where conversion is fastest. Look at any client who has bought two or more projects in the past eighteen months. That repeat pattern is an unpriced retainer. Take the pattern to them: “You’ve briefed us four times this year. Here’s what an ongoing arrangement looks like – better availability, faster turnaround, a senior team that knows your business, at a fee that rewards the commitment.” Most clients say yes, because predictability serves them too.
Next, productise the ongoing version of your service. Project agencies sell outcomes with end dates; retainer agencies sell capabilities with cadences. A brand project becomes brand management. A website build becomes continuous optimisation. A campaign becomes an always-on programme with quarterly planning cycles. The skill is defining a recurring scope that’s genuinely valuable rather than a bag of hours – retainers built on vague “support” erode into over-servicing and get cancelled at the first budget review.
Then fix the commercial architecture. Twelve-month terms as the default, not the exception. Sixty or ninety-day notice periods. Annual fee reviews built into the contract. Scope defined by deliverables and cadence, not hours. Every one of these clauses is invisible to you day-to-day and highly visible to a buyer in diligence.
Finally, change what you sell to new clients. Lead with the ongoing engagement and position the project as the entry point to it. Agencies stuck at Standstill sell the project and hope for more. STANDOUT agencies design the relationship from the first proposal.
The Bottom Line
One last thing: this lever takes two to three years to pull. Buyers don’t value the mix you have at the point of sale – they value the track record behind it. A retainer signed six months before you go to market carries little weight in diligence; what earns the premium is contracted revenue with two or more years of renewals behind it. So the realistic timeline is: convert your repeat clients and rebuild your contracts in year one, accumulate renewal history in year two, go to market in year three with a revenue base a buyer can model with confidence. And if you’re not planning to sell at all, pull the lever anyway – everything that makes an agency valuable to a buyer also makes it calmer, more profitable, and easier to run. The agency that’s ready to sell and the agency that’s a pleasure to own are the same agency. Valuation is just the scoreboard.
Frequently Asked Questions
What EBITDA multiple do marketing agencies sell for?
Most independent agencies sell for between 3x and 7x EBITDA. The biggest driver of where you land in that range is revenue quality: agencies with 80%+ recurring revenue typically command 5-7x, while project-heavy agencies settle for 3-4.5x. Positioning, growth rate, and founder dependency move the number within those bands.
How much recurring revenue should an agency have before selling?
Aim for 80% or more of revenue on contracted retainers, with at least two years of renewal history. That’s the threshold at which buyers stop treating you as a project business and apply the premium multiple. Between 50% and 80% you’ll get partial credit; below 50% you’ll be valued as project-based.
Does repeat project work count as recurring revenue?
Not in a buyer’s eyes. Repeat work from loyal clients is relationship revenue – there’s no contract obligating it to continue, so acquirers discount it heavily in diligence. Only contracted retainers with defined terms, notice periods, and renewal history get full recurring treatment.
How long does it take to shift an agency from project to retainer revenue?
Realistically two to three years. Converting existing repeat clients takes six to twelve months; building the renewal history buyers want to see takes another one to two. Retainers signed shortly before a sale carry little weight in diligence, so the work has to start well before you plan to exit.
