Advance invoice: We want to pre-invoice, e.g. 50% of an order with inventory items. We can not activate "invoice in advance of item item fulfillment". Any ideas to make a good process out of this?

I’ve seen it where you add a non inv or other charge item to the invoice for the 50% Then add a negative line for the same as an offset

Thank you @MGBC! I will look into it, we have a 3PL so it must work from there too..
