we use SO and Cash Sales for our eCom transactions but wanted to test a Paypal integration. when I did that it creates a SO from Celigo and get a Invoice,. what could be happening??

What eComm platform? We had to discontinue using Paypal and SCA because it was a mess. Returns were the worse. Maybe that was specific to our setup.

Hello, Whether a SO is converted to Invoice or cash sale depends on whether it has billing information entered correctly in the billing subtab
