Frequently asked questions

What is Customer Acquisition Cost (CAC)?

CAC = Total marketing and sales spend ÷ Number of new customers acquired. It measures how much it costs to win one new customer.

What is a healthy LTV:CAC ratio?

3:1 or higher is healthy — meaning the customer generates 3× what it cost to acquire them. Below 1:1 means you're spending more to acquire customers than they're worth.

How do I reduce CAC?

Improve conversion rates, invest in referral programs (Tregovia's referrals module), focus on organic channels like SEO and reviews, and increase repeat business through automated follow-ups.
