Common questions

      

        What counts in CAC?
        
All customer-facing spend: paid ads, sales team salary, marketing team salary, tools, agency fees, content production. Exclude engineering and product.

      

      

        What's a good payback period?
        
SaaS SMB: under 12 months. Enterprise: 12-24 months. B2C: 3-6 months. Longer = you need more cash to fund growth.

      

      

        How to lower CAC?
        
Content marketing / SEO (slow but compounds), referral programs, partnerships. Paid ads have highest CAC — use last, not first.
