How to do a credit transaction in LS Retail?

Hi Experts,

I’m new in implementation of LS Retail. We are currently implementing NAV and LS Retail. My question is, how can i set up in LS retail if there will be no Tender received. Transaction is by credit. How do LS cater credit transaction and how does it affect the GL Accounts. Thanks.

Sorry If my question is a little bit basic. I really cannot find any LS Retail manual that is as descriptive as the NAV Manuals. Thank you.
