Your invoice is from a Dutch supplier and has a positive amount due, but it does not include payment instructions.

Intra-community B2B supplies are reverse-charged to the customer, so the seller must show a 0 rate. It is the category-K member of the EN 16931 line-rate family (BR-S-05, BR-Z-05, BR-E-05, BR-AE-05, BR-G-05, BR-O-05).
