The process that you go through to acquire a paying customer is clearly 

repeatable

repeatable. 

If your process involves salespeople, you can add new hires and they can achieve the same 

productivity level as the original sales team.

If it is a touchless web sales model, your web traffic converts in a predictable way through 

your web site.

The process is scalable. 

You can increase the sources of your leads and/or web traffic without reaching a near‐term 

limit. 

The resources (e.g. salespeople) in your conversion funnel can easily be scaled without 

reaching a near‐term limit

Your cost to acquire a customer [http://www.forentrepreneurs.com/startup‐killer/]

customer’s lifetime.

In a SaaS business I recommend that LTV should be more than three times higher than CAC.

It should also be possible to recover CAC in less than 12 months for a capital‐efficient startup.
