Instructions once you are onboarded

To ensure we can receive and process your eInvoices quickly, you’ll need the Ministry’s New Zealand Business Number (NZBN).

Our NZBN is:

To help us ensure smooth processing and payment of your invoices, we’d like to remind you to make sure your invoices include a purchase order number.

• Please ensure your MSD contact provides you with a Purchase Order when they request any goods or services from you.
• The Purchase Order must be in the format, starting with MSDP, followed by 8 digits (as shown on the purchase order notification).
• Please reference the Purchase Order Line number for invoices related to a multi-line purchase order (as shown on the purchase order notification).

To ensure we can receive and process your eInvoices make sure they:

• are addressed to The Ministry of Social Development
• are a “tax invoice” and clearly show you PO number, and your NZBN
• include your GST number, and
• your supplier/contact email address (so we can get in touch if we have any queries). 

If your eInvoice is rejected from our gateway provider, we will be in contact with you to correct the invoice for resending to the Accounts Payable Team.

Please also note that we can accept credit notes via the e-invoicing process.
