Customer Reports

SUGGESTED

I have very limited experience using this program and have a very basic question.

We have two types of customers, COD and account customers. We would like to be able to run reports for sales from both groups separately. 

What is the best way to differentiate the two types when creating the customers?

How do I run a report that would only include sales totals from one customer type.

Thanks for any help I can get on this!
