What does it mean to 'short pay' or 'block' an invoice, and when is each used?

Intermediate

Answer

Short paying means paying less than the invoiced amount—used when part of the delivery is missing, damaged, or overcharged and a credit is expected. Blocking (holding) stops the entire invoice from paying until an exception is resolved. Short pay keeps the supplier partly paid; blocking is used when the whole invoice is in dispute.
Real-world example An invoice billing 100 units when only 90 arrived is short-paid to 90 units, with the balance pending a credit note.
