There are two fields in Order Entry that look to be related. They also have corresponding fields in Customer Entry for default values. We don’t use auto-invoicing, but the help documentation makes it sound like no invoice is created and that the Customer pays directly to the pack.
Ah you misunderstood, I mean look for existing BPM’s - I see you say there are no BPM’s on the system so my suggestion isn’t relevant. I am aware of what @tsmith mentioned, but I thought that would only generate an invoice when you use the freight button and not any time you hit save…
Check in the Company Configuration > Modules > Sales > Order for “Save Shipment for Invoicing”. If that box is not checked then invoicing is not done through Epicor (meaning they’re using some other software for their invoicing). I’ve never worked with that box not checked, so I don’t know what the results would be, but it’s worth a look.
