Calculate CAC consistently
Customer acquisition cost is total sales and marketing spend in a period divided by new customers won in that period. Include salaries, tools, agency fees, and ad spend. Calculate it the same way every quarter, and segment it by channel or customer type when you can.
Tighten your ICP
The fastest way to lower CAC is to stop pursuing accounts that rarely close. Compare win rates and cycle lengths by segment. Shifting effort toward the best segment often lowers CAC without any change in spend.
Improve conversion before adding volume
Look at each step from visit to closed deal. A small improvement in demo-to-opportunity or opportunity-to-close conversion lowers CAC across every channel at once. Common fixes include faster lead response, clearer pricing pages, and better qualification.
Make sales time count
Sales salaries are often the largest part of CAC. Route only qualified leads to account executives, automate scheduling and follow-up, and give reps clear disqualification criteria so they spend less time on deals that will not close.
Invest in compounding channels
Paid acquisition costs rise as you scale. SEO, referrals, partnerships, and community take longer to start but get cheaper per customer over time. Shifting even a small share of budget toward them lowers blended CAC over several quarters.
Watch payback, not just CAC
A higher CAC can be fine if customers pay more or stay longer. Track CAC payback period, the months of gross margin needed to recover acquisition cost, alongside CAC itself.
