Purchase/contract orders and invoices

All goods/services/works provided to us must be supported by a valid purchase/contract order. Once we have approved a purchase/contract order, we will send you the correct purchase/contract order number and line number. You must include this in your invoice.

Valid purchase/contract order numbers are 9 digits long and start with a ‘4’.

If you have not received your number, please contact the person you have been working with at Watercare. If your details are incorrect on the purchase/contract order or you wish to change your bank account details, please email [email protected].
 

Standard terms of purchase

Our purchase order standard terms and conditions contain the default terms and conditions that apply to all purchase orders created by us, unless otherwise agreed in a contract or within the purchase order.

Please send your invoices punctually. We need to receive invoices for the previous month by 5th of the following month, to allow time for processing.

Note: Invoices should be dated for the month that the goods/services/works were supplied. For example, an invoice for services carried out in the month of January should be dated 31 January at the latest.

Here’s how you can avoid delays

• You must include an approved purchase/contract order number and line number on your invoice (we cannot pay invoices and may return invoices without this number)
• ​​You can send your Watercare contact a copy of the invoice (mark it clearly with the word ‘copy’)
• Your invoice should also contain:
  • The words ‘Tax Invoice’ in a prominent place
  • Your name and GST number
  • The date of issue
  • Our name and address: Watercare Services Limited, Private Bag 92521
    Victoria Street West, Auckland 1142
  • A description of your goods/services/works
  • The quantity or volume of your goods/services/works
