Calculating CAC When You Have SLG and PLG Motions | SaaS Metrics School | CAC
Welcome to SaaS Metrics School with Ben Murray! Today, we’re unpacking Customer Acquisition Cost (CAC) when managing both Sales-Led Growth (SLG) and Product-Led Growth (PLG) strategies. Accurate CAC segmentation for SLG and PLG is essential for understanding acquisition costs, sales and marketing efficiency, and maximizing growth. I’ll break down why CAC is more than a single number and how dividing SLG and PLG metrics can improve your growth insights.
Why Separate SLG and PLG for CAC?
CAC is vital in SaaS, affecting metrics like CAC payback, Lifetime Value (LTV), and Gross Expense CAC. However, if you have both sales-led and product-led motions, combining them can misrepresent true acquisition costs. SLG relies on a direct sales team, while PLG focuses on users engaging with your product independently. Without segmenting SLG and PLG new customer wins, efficiency metrics may appear misleading, leading to poorly informed decisions.
Segmenting New Customer Wins and Allocating Sales and Marketing Expenses
To calculate CAC accurately, segment new customers based on acquisition source. Avoid the common error of lumping all new customers under total sales and marketing expenses, which can distort actual costs for each motion. Allocate sales and marketing expenses specific to each motion, and consider how R&D costs tied to PLG may impact acquisition, especially when product-led strategies heavily involve engineering resources.
PLG to SLG Handoff: Managing Transition Costs
For some SaaS companies, customers start through PLG but transition to SLG as they require enterprise support. This PLG-to-SLG handoff can incur additional SLG costs, which should be factored into CAC calculations. Segmenting these stages offers insights into your customer journey and helps optimize budget allocations.
Key Benefits of SLG and PLG CAC Separation
1. Accurate Efficiency Metrics: Separating SLG and PLG ensures reliable sales and marketing efficiency data.
2. Improved Budget Allocation: Allocate budgets more effectively based on actual CAC data.
3. Better Decision-Making: Refine acquisition strategies based on the cost-effectiveness of SLG and PLG.
Final Thoughts
Understanding and calculating CAC across SLG and PLG motions allows you to paint a more accurate picture of your SaaS company's customer acquisition efforts. Whether you’re a SaaS founder, CFO, or finance leader, segmenting CAC will lead to better financial insights, improved planning, and smarter growth decisions.
