I respectfully disagree @MarkKotyla . It really can be a problem to receive the invoice before the goods. They need to be sure that the quantity they are being invoiced for matches the quantity of goods having been received. In this age of electronic sending of invoices, I can see how the invoice might beat the physical receipt of goods, but it would be helpful to have an option to prevent/alert the quantity on invoice being received greater than the quantity of goods received.
