Great question—LTV and CAC for accounting clients can vary based on service type, business size, and service frequency, but here’s a breakdown based on typical client behavior in small business accounting and personal tax services.

🧠 Upsell potential: Many small businesses start with basic services and grow into more profitable relationships (e.g. adding tax planning, advisory, or CFO services).

  • CAC Range: Typically $100 to $500, but can be reduced through SEO, referrals, or bundled offerings.
