Executive Summary
Customer Acquisition Cost (CAC) isn’t one-size-fits-all for MSPs. Whether you’re growing through referrals or scaling with a full sales team, understanding and optimizing your CAC is crucial for sustainable growth. This guide shows you how to calculate, track, and improve your CAC at every stage of your MSP’s journey, emphasizing its role within the broader context of a business strategy.
KEY STAGES OF CAC
- Early Stage: Often referral-driven with varying CAC
- Growth Stage: Balanced CAC with marketing investment
- Enterprise Stage: Strategic CAC for larger contracts
“Many MSPs don’t look at their customer acquisition costs until they’re forced to by outside investors or advisors,” explained Ken Peterson, President and Founder of Next Level Now, a company focused on providing fractional CFO and Controller services to MSP’s. “But understanding your CAC early on can prevent costly mistakes as you scale.”
What is Customer Acquisition Cost?
At its most basic, CAC is the total cost of gaining a new customer divided by the number of new customers acquired. Understanding the cost to acquire customers is crucial for analyzing marketing return on investment and identifying the most cost-effective channels. However, the real insight comes from understanding what goes into that total cost.
CAC FORMULA
Customer Acquisition Cost = Total Acquisition Expenses / Number of New Customers Acquired
Direct Costs to Include:
- Sales team salaries and commissions
- Marketing campaign expenses
- Website and SEO investments
- Event and networking costs
- Sales tools and CRM licenses
Hidden Costs Often Missed:
- Technical staff time in sales meetings
- Proof of concept deployments
- Security assessments for prospects
- Proposal development time
- Contract negotiation hours
- Lead qualification effort
“One of the biggest mistakes I see is MSPs only tracking their marketing spend,” noted Julie Ferraz, fractional controller at Next Level Now. “They forget about the labor costs for sales staff, the time spent on lead conversion, and especially the technical resources involved in the sales process. These hidden costs can account for up to 70% of your true CAC.”
CAC Varies by Business Stage
Your CAC isn’t just a number – it’s a reflection of your growth strategy and business stage. Let’s break down what healthy CAC looks like at different phases:
Early Stage MSP
- Growth often driven by referrals and word-of-mouth
- Marketing spend varies by strategy
- May have dedicated sales or founder-led sales
- CAC typically lower but varies by approach
- Focus on building strong client relationships
Growth Stage MSP
- Mix of referral and marketing-driven growth
- Dedicated sales resources
- Increasing marketing investment with effective marketing strategies
- Moderate CAC with clear tracking
- Expanding market presence
Enterprise-Focused MSP
- Sophisticated sales and marketing operations, including optimizing each stage of the sales funnel
- Higher CAC justified by larger contracts
- Longer sales cycles with multiple stakeholders
- Strategic investment in growth
- Often targeting specific verticals
“The key is matching your CAC strategy to your business stage,” said John Parins, Fractional CFO at Next Level Now. “If you’re successfully growing through referrals with minimal costs, that’s perfectly valid. The problems start when MSPs try to jump stages without understanding the CAC implications.”
Calculating CAC at Your Stage
Let’s look at how different MSPs might calculate and interpret their CAC based on real scenarios:
Analyzing monthly recurring revenue alongside CAC and Lifetime Value is crucial to assess the efficiency of a company’s revenue generation and customer acquisition strategies.
CAC BY BUSINESS MODEL
- Referral-Based Growth: Lower acquisition costs, focused on relationship building
- Marketing-Driven Growth: Balanced investment in multiple channels
- Enterprise-Focused: Higher investment with larger contract values
Early Stage Calculation Example
“Many MSPs start with very efficient client acquisition,” explained Julie Ferraz. “When you’re primarily growing through your network and referrals, your customer acquisition cost might only include the time spent nurturing relationships and basic marketing infrastructure.”
Early Stage CAC Components Might Include:
- Website maintenance
- Networking event costs
- Time spent on referral relationships
- Basic marketing materials
- Proposal development time
Growth Stage Calculation Example
At this stage, MSPs typically see their CAC increase as they invest in systematic growth. “The trick is balancing increased marketing spend with efficient conversion,” noteed Kenneth Peterson. “You’re investing more, but you should be tracking returns carefully.”
Growth Stage Additional Components:
- Dedicated sales salaries
- Marketing automation tools
- Lead generation campaigns
- Sales enablement materials
- Professional event participation
Enterprise Focus Calculation Example
“When targeting larger contracts, your CAC naturally increases,” explained John Parins. “The key is ensuring your larger deal sizes and improved margins justify the higher acquisition costs.”
Enterprise Focus Additional Components:
- Multiple stakeholder management
- Complex proposal development
- Proof of concept investments
- Industry certification costs
- Advanced security assessments
CAC WARNING SIGNS
- CAC increasing without corresponding revenue growth
- Sales cycle length growing without larger deals
- High variation in acquisition costs between similar clients
- Marketing spend increasing without improved conversion
Understanding Your Numbers
Each business stage has different customer acquisition cost benchmarks. Here’s what to consider when evaluating yours:
Early Stage Benchmarks
- Focus on cost per qualified lead
- Track time spent on sales activities
- Monitor referral source effectiveness
- Measure conversion rate by lead source
- Calculate time to close
Growth Stage Benchmarks
- Compare CAC across marketing channels
- Evaluate sales team efficiency
- Analyze CAC by service type
- Track CAC trends over time
- Monitor customer lifetime value ratio
Enterprise Stage Benchmarks
- Segment CAC by deal size
- Calculate ROI by market segment
- Compare CAC to industry averages
- Analyze win rates versus investment
- Measure multi-year contract impact
“The key isn’t just calculating CAC,” said Julie Ferraz. “It’s understanding what the numbers tell you about your business model and growth strategy. Sometimes a higher CAC is perfectly acceptable if your service model and margins support it.”
Optimizing CAC at Every Stage
OPTIMIZATION QUICK WINS
- Document and streamline your sales process
- Track lead source effectiveness
- Measure time spent on proposals
- Monitor technical team sales involvement
- Calculate conversion rates by channel
Early Stage Optimization
When you’re just starting out or running a smaller MSP, optimization focuses on efficiency and relationship building.
“At the early stage, it’s not about minimizing every cost – it’s about understanding where your costs are,” explained Ken Peterson. “Many MSPs can grow quite effectively with minimal marketing spend if they’re strategic about it.”
Key Focus Areas:
- Document your current acquisition process
- Track time spent on sales activities
- Measure referral program effectiveness
- Optimize proposal creation time
- Monitor networking ROI
Growth Stage Optimization
As your MSP scales, systematic optimization becomes crucial. “This is where many MSPs hit what we call the ‘valley of death’ around $5 million in revenue,” noted Julie Ferraz. “They’ve grown naturally to this point, but then they start dumping money into sales and marketing without understanding their CAC. That’s when things can go sideways fast.”
Optimization Strategies:
- Standardize your sales process
- Implement proper tracking systems
- Test and measure marketing channels
- Improve lead qualification
- Reduce technical team sales time
Enterprise Focus Refinement
At this stage, optimization often means balancing higher customer acquisition costs with larger contract values.
“For MSPs targeting larger clients, it’s about strategic investment,” explained John Parins. “You might have higher CAC, but your focus should be on efficiency in the enterprise sales process and ensuring your margins justify the investment.”
Focus Areas:
- Streamline enterprise sales cycle
- Improve proposal win rates
- Optimize proof of concept process
- Enhance sales team training
- Refine target market selection
Value Communication at Every Stage
VALUE DEMONSTRATION
Focus on showing value through:
- Clear solution benefits
- Industry expertise
- Client success stories
- Specific problem-solving
- ROI demonstrations
“Speed up your acquisition by quickly demonstrating value,” advises Julie Ferraz. “Whether you’re small or large, clients need to understand how you’ll solve their specific problems. The faster you can demonstrate this, the lower your CAC will be.”
Value Demonstration Strategies:
- Create targeted solution packages
- Develop clear value propositions
- Build compelling case studies
- Share relevant client success stories
- Demonstrate industry expertise
Taking Action: Implementing CAC Tracking and Optimization
ACTION STEPS
- Start tracking all acquisition costs
- Document your sales process
- Measure key conversion metrics
- Implement optimization strategies
- Review and adjust regularly
Step 1: Begin Tracking
Start with these foundational measurements:
- List all customer acquisition activities
- Track time spent on sales and proposals
- Document marketing expenses
- Record technical team sales time
- Note networking and event costs
“The sooner you start tracking, the better off you are,” explained Julie Ferraz. “You don’t need complex systems – you just need to consistently capture the data that shows you where your money and time are going.”
Step 2: Analyze Your Current Position
Evaluate your starting point:
- Calculate your basic CAC
- Review your client acquisition sources
- Analyze sales cycle length
- Assess conversion rates
- Evaluate client profitability
Step 3: Identify Improvement Opportunities
Look for areas to optimize:
- High-cost activities with low returns
- Inefficiencies in your sales process
- Underperforming marketing channels
- Time-intensive client acquisition methods
- Opportunities for automation
Step 4: Implement Changes Systematically
“Don’t try to change everything at once,” advised Ken Peterson. “Pick the areas where you can make the biggest impact with the least disruption to your current business, and start there.”
Focus on:
- One process improvement at a time
- Clear metrics for success
- Regular progress reviews
- Team feedback and adjustments
- Documented results
Step 5: Monitor and Adjust
Create a regular review cycle:
- Monthly CAC calculations
- Quarterly trend analysis
