Recurring Revenue for Agencies: Stop Selling Projects

Recurring revenue for agencies is the difference between a business that compounds and one that constantly restarts. Agencies that build retainer-based, subscription, or productised income streams grow more predictably, retain better talent, and command higher valuations than those running on project cycles alone.

Most agency leaders know this. Very few have actually built it properly.

Why Project Revenue Is a Structural Problem

I have run agencies on both sides of this. When I was building out iProspect’s UK operation, growing the team from around 20 people to over 100, one of the things that became clear early was that project revenue creates a particular kind of organisational anxiety. You close a big piece of work, the team celebrates, and then three months later everyone is quietly aware that the work is nearly done and nothing equivalent has been signed to replace it.

That anxiety is not just cultural. It has real commercial consequences. You understaff to protect margin, which means you deliver less and retain clients poorly. Or you overstaff to deliver well, which means your bench costs eat you alive between projects. Neither outcome is good. Both are symptoms of the same structural problem: you are running a business where revenue disappears at the end of every engagement.

The agencies I have seen grow most reliably are the ones that treat recurring revenue as a strategic priority, not a nice-to-have. They build toward a position where a significant portion of their income is contractually committed before the month starts. Everything else, the project work, the one-off campaigns, the ad hoc briefs, becomes upside rather than survival.

If you want a broader view of how go-to-market thinking applies to agency growth, the Go-To-Market and Growth Strategy hub covers the structural decisions that matter most for service businesses building sustainable revenue.

What Recurring Revenue Actually Means for an Agency

There is a version of this conversation that gets too abstract too quickly. So let us be specific about what recurring revenue looks like in practice for an agency.

The most common form is the ongoing retainer: a client pays a fixed monthly fee for a defined scope of work, typically with a notice period of 30 to 90 days. Done well, this is stable, predictable, and scalable. Done badly, it becomes a vague arrangement where the client asks for more and more, the agency says yes to protect the relationship, and the margin erodes to nothing within six months.

The second form is the productised service: a defined deliverable at a fixed price, sold on a recurring basis. Think monthly SEO reporting, a weekly content package, or a quarterly brand audit. The scope is fixed, the price is fixed, and the client buys it on an ongoing subscription. This model is particularly useful for agencies that want recurring revenue without the complexity of managing open-ended retainers.

The third form is performance-based recurring revenue, where the agency takes a percentage of media spend, revenue generated, or some other commercial metric. This can be extremely lucrative if the underlying performance is strong, but it introduces variability that undermines the predictability you are trying to build. I have seen this work well in paid media and affiliate, less well in brand and creative, where the link between agency output and commercial outcome is harder to isolate cleanly.

Each model has different implications for how you staff, price, and sell. The mistake most agencies make is treating all three as interchangeable when they require fundamentally different commercial structures.

The Pricing Problem That Kills Retainer Margins

Most agencies price retainers by working out their cost base and adding a margin on top. This is understandable and almost entirely wrong.

Pricing on cost means your ceiling is determined by your internal efficiency, not by the value you deliver to the client. If you are running a paid search programme that generates three million in revenue for a client, and your retainer is priced at a modest percentage of your team’s time, you are leaving an enormous amount of money on the table. The client is not paying for your hours. They are paying for the outcome.

I saw this clearly when I was managing large-scale paid search at lastminute.com. A well-structured campaign could generate six figures of revenue in a single day from a relatively modest investment of time and budget. The commercial value of that work bore almost no relationship to the hours it took to set up and manage. If an agency had been running that campaign on a cost-plus retainer, they would have been dramatically undercharging for the outcome they were delivering.

Value-based pricing for retainers requires you to have a clear understanding of what your work is worth to the client commercially. That means knowing their margins, their customer lifetime value, their cost of acquisition before you got involved, and what improvement you are delivering. Most agencies do not have this conversation. They talk about deliverables and timelines and then present a number based on day rates. That is a cost conversation, not a value conversation.

The agencies that price well on retainers are the ones that have done enough discovery to understand the client’s commercial model before they quote. They know what a percentage point of improvement in conversion is worth. They know what the client is currently spending on the problem they are solving. They price against that context, not against their own cost base.

How to Shift Existing Clients from Projects to Retainers

The most common question I get asked about recurring revenue is not how to build it from scratch. It is how to convert the clients you already have.

The short answer is that you do not pitch a retainer. You earn one.

A client agrees to a retainer when they trust that the ongoing relationship will deliver more value than the cost of maintaining it. That trust is built through project work that consistently delivers, through conversations that go beyond the brief, and through demonstrating that you understand their business well enough to be genuinely useful on an ongoing basis.

When I was at Cybercom in the early days, I remember being handed the whiteboard pen in a Guinness brainstorm when the founder had to leave for another meeting. The room was full of experienced people, and the internal reaction, mine included, was something close to panic. But the instinct I fell back on was to ask questions about the brand’s commercial context before proposing any creative direction. That habit, understanding the business before proposing the solution, is exactly what turns a project relationship into a retainer relationship. Clients keep you around when they feel you are thinking about their business, not just executing their briefs.

Practically, the transition from project to retainer works best when you can identify a specific ongoing need that your project work has surfaced. You have just finished a campaign audit. The natural follow-on is a monthly optimisation retainer. You have delivered a website build. The natural follow-on is a performance monitoring and CRO retainer. The retainer should feel like the logical continuation of work the client already values, not a new product being sold to them.

Scope definition matters enormously here. Vague retainers create vague expectations, which create scope creep, which create resentment on both sides. The best retainer agreements I have seen are specific about what is included, what is not, and what the process looks like when the client wants something outside the agreed scope. That specificity protects your margin and actually improves the client relationship because everyone knows where they stand.

Productised Services: The Fastest Route to Recurring Revenue

If your agency does not yet have the client relationships or the positioning to sell open-ended retainers, productised services are the most direct route to building recurring revenue.

The logic is straightforward. You take a service you already deliver and package it with a fixed scope, a fixed price, and a fixed delivery process. The client knows exactly what they are buying. You know exactly what you are delivering. The repeatability means you can systematise the work, which improves your margin over time as your team gets faster and more efficient at the delivery.

Good productised services share a few characteristics. They solve a specific, recurring problem rather than a one-off need. They have a clear output the client can see and evaluate. They are priced at a level that is easy for a client to approve without a lengthy procurement process. And they are designed so that the delivery process can be documented and delegated, which means your senior people are not required for every instance of the work.

The mistake agencies make with productised services is trying to productise their most complex, high-value work. That work is complex because it requires judgement, context, and experience that cannot easily be systematised. Productise the repeatable, lower-complexity work instead. Use the recurring revenue that generates to fund the senior capacity you need for the complex, higher-margin work.

For agencies thinking about how to structure growth systematically, it is worth looking at how growth-oriented businesses approach scalable service delivery. The principles that apply to product businesses, repeatability, systematisation, and clear value metrics, apply equally to agency service design.

The Operational Changes Recurring Revenue Requires

Building recurring revenue is not just a sales and pricing problem. It changes how you need to run the agency operationally.

The most significant change is in how you think about capacity. On a project model, you staff up for projects and wind down between them. On a retainer model, you need consistent capacity to deliver consistent work. That means your hiring decisions become more strategic and less reactive. You are building a team for the ongoing workload, not scrambling to resource individual briefs.

It also changes your account management model. Project relationships are episodic. Someone briefs the work, you deliver it, there is a review, and then there is often a gap before the next engagement. Retainer relationships are continuous. That requires a different kind of account management, one that is proactive rather than reactive, that brings ideas to the client rather than waiting to be briefed, and that monitors performance and flags issues before the client notices them.

When I was turning around a loss-making agency business, one of the first things I looked at was the ratio of reactive to proactive client communication. In the agencies that were struggling, almost all client communication was reactive, responding to briefs, answering complaints, chasing approvals. In the agencies that were growing their retainer base, account managers were bringing commercial insights to clients without being asked. That difference in behaviour was directly correlated with retainer renewal rates.

Reporting also needs to change. Retainer clients need to see ongoing evidence that the relationship is worth maintaining. That means regular, clear reporting that connects your work to their commercial outcomes, not just activity metrics. How many posts were published is not a retainer-sustaining metric. What impact did those posts have on organic traffic, lead quality, and pipeline is. The Forrester intelligent growth model makes a similar point about connecting marketing activity to business outcomes rather than reporting on process.

What a Healthy Recurring Revenue Mix Looks Like

There is no universal answer to what percentage of revenue should be recurring, but there are some useful reference points.

Agencies that are valued at a premium in acquisition conversations typically have 60 to 70 percent of their revenue on retainer or subscription arrangements. That level of contracted revenue gives a buyer confidence in the forward earnings of the business. Below 40 percent, the business looks much more like a project shop, and the valuation reflects that uncertainty.

Within the recurring revenue base, concentration risk matters. If 60 percent of your retainer revenue comes from one client, you do not really have a stable recurring revenue business. You have a dependency. The target should be a retainer base where no single client represents more than 20 to 25 percent of total recurring income. That gives you resilience when a client relationship ends, as they always eventually do.

Project revenue still has a role. It is often where new client relationships start, and it can generate significant margin if it is scoped and priced well. The goal is not to eliminate project work but to ensure it is not the foundation of your business model. Project work should sit on top of a retainer base, not beneath it.

Agencies scaling toward this kind of revenue mix often find it useful to think about growth in the same systematic way that BCG describes for scaling business models with agile structure. The principle of building repeatable systems before scaling headcount applies directly to how agencies should approach recurring service delivery.

The Retention Problem Nobody Talks About

Agencies spend a lot of time thinking about how to win retainers. They spend considerably less time thinking about how to keep them.

Retainer churn is the silent killer of recurring revenue models. You can be winning new retainers consistently and still see your recurring revenue base stagnate if you are losing clients at the same rate you are winning them. The net effect is a lot of sales effort for no net growth.

The agencies with the best retention rates share a few consistent behaviours. They set clear expectations at the start of every retainer relationship, including what success looks like and how it will be measured. They have a structured onboarding process that gets the client to value quickly, rather than spending the first two months on admin and access requests. They review the retainer formally every six months, which gives both sides an opportunity to recalibrate scope and expectations before frustrations accumulate. And they treat the renewal conversation as a strategic moment, not a formality.

Understanding what is working and what is not within a retainer relationship requires honest feedback mechanisms. Tools like Hotjar’s approach to feedback loops illustrate how continuous input shapes better outcomes, and the same principle applies to agency client relationships. Regular, structured check-ins where you genuinely ask what is working and what is not will surface problems before they become cancellations.

The agencies I have seen lose retainers most often lose them not because the work was bad, but because the client felt the agency had stopped caring about their business. That is an account management failure, not a delivery failure. And it is entirely preventable.
