- Retainer pricing transforms unpredictable project income into stable, reliable monthly revenue.
- Price retainers based on value delivered to clients, not just hours worked.
- Clear scope boundaries prevent retainers from becoming unprofitable all-you-can-eat service buffets.
Are you tired of the feast-or-famine cycle that comes with traditional agency pricing and project-based work? One month your marketing agency is overwhelmed with client projects, and the next you're scrambling to find new business to keep the lights on.
If unpredictable revenue is keeping you up at night, you’re not alone. In my experience working with hundreds of agency owners, cash flow volatility ranks as their number one operational challenge—and it’s precisely why retainer pricing models have become the gold standard for sustainable agency growth.
Let me show you how retainer pricing works and how you can implement it to create predictable revenue while delivering exceptional value to your clients.
What is retainer pricing?
Retainer pricing is a business model where clients pay a fixed, recurring fee in advance for access to your agency’s services over an agreed-upon period—typically monthly. Unlike project-based pricing, where payment is tied to deliverables, retainer pricing creates a consistent revenue stream in exchange for ongoing value.
Think of it as a subscription to your agency’s expertise rather than a one-time purchase.
Examples of marketing agency retainers
To make this concrete, here are several examples of how marketing agencies can structure their retainer offers:
SEO agency retainer: $3,500/month for comprehensive search optimization, including technical audits, content optimization, and monthly reporting
Social media management retainer: $2,000/month for daily posting across three platforms, community management, and performance analytics
Full-service digital marketing retainer: $7,500/month covering SEO, content creation, social media management, and PPC campaign management
CMO-as-a-service retainer: $10,000/month for strategic marketing direction, team leadership, and implementation oversight
With that said, retainer pricing isn’t just about repackaging your services—it’s about restructuring your entire approach to client relationships to emphasize ongoing value rather than one-off deliverables.
5 retainer pricing models for agencies
Let’s look at the most common retainer pricing models used by successful marketing agencies.
1. Hourly credits retainer
In this model, clients pre-purchase a set number of hours each month.
How it works: The client pays upfront for 20 hours of agency time at $150/hour ($3,000 monthly retainer). They can allocate these hours across different services as needed.
Best for: Agencies offering diverse services where client needs vary month-to-month.
Tip: Always implement a "use it or lose it" policy where unused hours don’t roll over—this incentivizes clients to fully utilize their investment while protecting your revenue stability.
2. Output-based retainer
This model provides specific, predefined services for a fixed monthly fee.
How it works: A client pays $4,500/month for a content marketing package that includes 4 blog posts, 15 social media posts, and 1 email newsletter.
Best for: Specialized agencies with standardized delivery processes.
3. Results-based retainer
Here, pricing is tied to specific performance metrics or outcomes.
How it works: Base fee of $2,500/month plus performance bonuses when certain KPIs are exceeded (e.g., $500 for every 10% increase in conversion rate above baseline).
Best for: Established agencies with proven track records that can confidently predict results.
4. Tiered retainer packages
The tiered retainer model offers different service levels at corresponding price points.
How it works:
Bronze package: $1,500/month for basic SEO and content
Silver package: $3,000/month adds social media management
Gold package: $5,000/month includes paid advertising management
Best for: Agencies looking to create clear upsell paths and accommodate different client budget levels.
5. Value-based retainer
This advanced approach bases pricing on the estimated business value delivered, rather than time or deliverables.
How it works: If your SEO services typically generate $15,000 in additional monthly revenue for similar clients, you might charge a $5,000 monthly retainer (capturing ⅓ of the value created).
Best for: Sophisticated agencies with strong analytics capabilities and confidence in their impact on client business outcomes.
5 retainer pitfalls that kill agency profits
After seeing hundreds of agencies implement retainer models, I’ve observed these recurring issues:
The scope creep trap
What it looks like: “Could you just quickly add this small task? It’ll only take a minute…”
Why it’s dangerous: These “quick tasks” compound, eating into your profit margins and setting precedent for future free work.
Prevention strategy: Document every out-of-scope request and implement a formal change order process through your client portal.
The always available expectation
What it looks like: Clients sending urgent requests at all hours expecting immediate response.
Why it’s dangerous: Creates team burnout and impossible service standards.
Prevention strategy: Clearly define response time expectations in your retainer agreement and set up automated responses for after-hours communications.
The value communication failure
What it looks like: “We’re not sure what we’re getting for our monthly fee anymore.”
Why it’s dangerous: Leads to contract cancellation when budgets tighten.
Prevention strategy: Implement monthly executive summaries that translate your activities into business impact metrics.
The resource allocation imbalance
What it looks like: Some retainer clients consuming significantly more resources than allocated in your pricing model.
Why it’s dangerous: Creates hidden unprofitability that’s often discovered too late.
Prevention strategy: Track time against all retainer clients and review profitability monthly.
The retainer as discount perception
What it looks like: “Since we’re paying you monthly, we should get a significant discount on your services.”
Why it’s dangerous: Positions your retainer as a commodity rather than a premium service.
Prevention strategy: Frame retainers around priority access, strategic continuity, and proactive service—never around discounted rates.
How to calculate profitable retainer fees
The most common mistake agencies make with retainers is underpricing. Let’s walk through a practical process to calculate profitable retainer fees.
Determine your actual costs
Start by calculating your true hourly costs. For a small agency, this includes:
direct labor costs (salaries + benefits)
overhead (office, software, utilities)
administrative time
management/oversight costs
Example: If your total monthly costs are $30,000 and your team has 640 billable hours available (4 people × 160 hours), your minimum cost per hour is $46.88.
Add your target profit margin
For sustainable agency growth, aim for a minimum 40-50% profit margin.
Example: $46.88 × 1.5 = $70.32 minimum hourly rate (with 50% margin)
Estimate service delivery requirements
For each retainer service, map out the typical hours required:
Content creation: 12 hours/month
SEO optimization: 10 hours/month
Client meetings: 4 hours/month
Reporting: 2 hours/month
Account management: 2 hours/month
Total: 30 hours/month
Calculate your minimum viable retainer
Multiply your required hours by your target hourly rate: 30 hours × $70.32 = $2,109.60
Add value-based premium
Fret not about charging solely based on hours—the true value of your services likely exceeds your time investment.
Consider adding a premium based on:
your specialized expertise
market positioning
client’s potential ROI
competitive landscape
For our example, adding a 30% value premium brings our monthly retainer to $2,742.48, which we’d likely round to $2,750.
Use cost-plus pricing to calculate your retainer
How to implement retainer agreements
Let’s look at how to successfully implement retainer pricing in your agency.
1. Define clear scope boundaries
The key to profitable retainers is precise scope definition:
specify exactly what’s included (and what isn’t)
set clear limits (e.g., "up to 4 rounds of revisions")
outline additional fees for work beyond scope
document communication expectations (response times, available hours)
2. Create a structured onboarding process
Successful retainers begin with thorough onboarding:
welcome packet with process overview
kickoff meeting to align on goals and expectations
collection of all required client materials and access
setting baseline metrics for performance tracking
introduction to your client management system
Tip: Use a client portal like SPP.co to streamline this process and set professional expectations from day one.
3. Establish value-demonstration protocols
Regular reporting is essential for retainer success:
weekly progress updates (brief email or portal update)
monthly comprehensive performance reports
quarterly strategy reviews to realign priorities
annual relationship reviews to discuss renewal terms
4. Implement change management procedures
Create a formal process for handling scope changes:
change request form in your client portal
impact assessment (how the change affects timeline/resources)
additional fee calculation when applicable
approval workflow before implementing changes
5. Build renewal and upsell strategies
Don’t leave renewals to chance:
proactive renewal discussions (60-90 days before contract end)
performance-based upsell opportunities
loyalty incentives for long-term commitments
exit interviews for non-renewing clients to improve offerings
Setting up retainer management in SPP.co
Let’s look at the specific steps to implement your retainer model in Service Provider Pro.
Create a retainer service
Navigate to Services → + Service and toggle “Recurring service” on. Set the billing cycle to monthly and define clear deliverables in the service description.
Optimize the client dashboard
By default, the client dashboard shows the order view. If your clients don’t have more than one order, it makes sense to replace the default dashboard with the onboarding page that you can customize.
Give the client tasks to fullfill (such as uploading brand information), add an introduction video, and give them an idea of the next steps to expect.
Automate your reporting
Service Provider Pro supports different reporting integrations that you can use natively, from Agency Analytics to Whatagraph. Set up reports for your clients and allow them to access them easily in the sidebar.
Configure client communication
Set up automated check-in messages at day 15 of each cycle. While SPP.co doesn't support internal automations, you can use the Zapier integration to set this type of automation up.
This systematized approach creates a professional experience while reducing the administrative overhead that often eats into retainer profitability.
Overcoming common client objections to retainer pricing
Even with a well-structured retainer model, you’ll face objections. Here’s how to address the most common ones.
It’s too expensive compared to project-based pricing
Response: I understand your concern about the investment. What makes our retainer model valuable is the continuous optimization and strategic oversight you receive. With project work, you’re paying for isolated deliverables—with our retainer, you’re investing in ongoing results and improvements that compound over time. Most clients see significantly better ROI by month three compared to one-off projects.
We don’t need all those services every month
Response: That’s actually why our retainer model is flexible by design. While the specific tactics may shift based on your needs each month, our team’s focus remains constant: driving [key metric] for your business. Some months we might emphasize content creation, while others we’ll focus more on conversion optimization—always prioritizing the highest-impact activities for your current situation.
We prefer to pay for results, not ongoing services
Response: I appreciate that perspective! That’s why we’ve structured our reporting to clearly demonstrate ROI. Additionally, we can explore our performance-based retainer option where part of our compensation is tied directly to achieving specific metrics we agree upon. This aligns our incentives even more closely with your business goals.
We’re not ready for a long-term commitment
Response: I completely understand wanting to ensure we’re the right fit before making a longer commitment. We offer a 3-month initial retainer that allows you to experience our process and see preliminary results before deciding on a longer-term engagement. Most of our successful client relationships began this way.

Frequently asked questions
How long should my retainer agreements be?
Most successful marketing agencies start with 3-6 month initial terms, then transition to 12-month agreements for renewal. The longer commitment allows for more strategic planning and typically yields better results for clients.
Should I require a deposit or setup fee alongside the retainer?
Yes, a one-time setup fee of 50-100% of the monthly retainer amount is standard practice. This covers the intensive onboarding process and demonstrates client commitment.
How do I handle scope creep in retainer relationships?
Document everything meticulously and implement a formal change request process. When clients ask for work beyond scope, respond with: "I’d be happy to help with that. Since it falls outside our current agreement, I’ll prepare a quick estimate for the additional investment required.
What’s the best billing cycle for retainers?
Monthly billing in advance is standard, though offering a discount for quarterly or annual prepayment (typically 5-10%) can improve your cash flow and reduce administrative overhead.
How do I transition existing project clients to retainers?
Start by identifying clients with recurring needs, then present a retainer option as a solution to their ongoing challenges. Frame it around the benefits: priority service, strategic continuity, and often cost savings compared to multiple separate projects.
Closing thoughts
Implementing retainer pricing in your marketing agency isn’t just about creating predictable revenue—it’s about transforming your entire business model to focus on long-term client success rather than one-off deliverables.
I’ve hopefully given you a comprehensive framework for developing, pricing, and implementing retainer services that benefit both your agency and your clients.
