Sales posted from internet sales

Sales posted from internet sales

We receive a sales report from our daily sales from our website. This is a CSV report. Can I upload these sales figures into a sales module and then be able to pull sales reports from this data?

 Also, We have suppliers and customers. I input information under contacts that were suppliers. They were turned into accounts as well as contacts. Is there a difference with regard to accounts being sales accounts or supplier accounts or do they all just reside in the same place?
