PO number
Electronic invoices and credit notes sent to DEAS must include a PO number. The number will guide your invoice to the right person at DEAS, who must confirm that the service was received.
If you enter the wrong number, your invoice may be rejected by our invoice system. For this reason, it is important that you, the supplier, ensure that you have the right PO number.
PO numbers for the claimants
The claimant, i.e. the person who commissioned the good/service, should give you the correct PO number.
If you are in doubt about the number, you should contact the claimant.
