/invoicing partial shipments.

I sell 40 units worth lets say $1,000 a piece and collect 50% as a down payment $20,000/$40,000. I then go to ship 8/40 and create an invoice for the second 50% of those 8 units. the invoice should be for $4,000 + shipping yet the invoice just applies the prepayment to cover this so it shows up as a PAID invoice. How do I fix this.

Hi Nick!

Could you provide screenshots or links to these invoices so I can take a look?
