Cost Per New Customer Acquisition (CPA)

The cost of getting the first order from a customer.
Cost per new customer acquisition (CPA) is a frequently used e-commerce metric that measures how much money you spend (or you would like to spend) for one new customer.
It’s important to realize that the focus of CPA is on the customer, not on the transaction. The expenses on an order made by a new customer can be -- for example -- 5-10x higher than expenses on an order made by a returning customer.
When you run a business determine the average investments that you have to make in order to get that first order by a new customer placed. To be as precise as possible include all costs, even human resources.
Compare this to the average that the first order a new customer places is worth.
