Entering daily sales summary from pos?

Hi everyone,

At the end of each day in our store, we complete a paper report (using data in our POS) that describes how much sales we had, tips to employees, gift certificates used, etc...

I am trying to enter this data into FA.  I am going to use a "New Sales Order Entry" to capture the entire days of sales into FA.  My question is that it is prompting me to create a Customer.  Should I create a "dummy customer" to represent in-store sales that come through the POS?  I see there is a way to create a "POS", is there a different process that I should follow to enter this data?

I am also looking for some guides on how to use FA in this fashion. I am willing to pay for a few hours of support as I get up and running.

Thanks.
Phillip
