What's a customer actually worth to your business?
Most clinics size their marketing budget against the first sale. The math gets very different when you factor in repeat visits, referrals, and the service-mix upgrade most paying customers make in year 1. Run your numbers — the LTV/CAC ratio you actually run on is the only number that tells you how much you can spend to acquire one.

Customer lifetime value (LTV)
