How the difference is calculated
Price effect = invoiced quantity × (invoiced price − agreed price). Quantity effect = (invoiced quantity − ordered quantity) × agreed price. Their sum equals invoice total minus PO total; the effects do not double count. Positive means the invoice total is higher.
Synthetic example: 10 units at $12 ordered and 12 units at $13 invoiced gives $120 ordered, $156 invoiced, $12 price effect and $24 quantity effect: $36 difference.
