Why can't I see or access the Set purchase order number button?

If you are on the Documents page of your Cloud Billing account and you don't see or cannot access the Set purchase order number button, the reasons could include the following:

  • The Cloud Billing account you are viewing is not configured to be paid by invoice, but rather is an automatically paid, self-serve/online account. Purchase order numbers can only be set on Cloud Billing accounts that are configured as an invoiced account.
  • You do not have the Cloud Billing account permissions needed to set or update the purchase order number associated with your invoiced account. Contact your Cloud Billing account admin.

Update the purchase order number on previously-issued invoices

To change the purchase order number on invoices that have already been issued, after setting the new purchase order number, regenerate each invoice you want to update — one invoice at a time.

To regenerate an invoice, do the following:

  1. From the Documents table, click the row of the invoice to view its details. A pop-up opens, showing you document header details including the invoice or memo number, amount, status, purchase order number, account details, and more.
  2. In the top right of the invoice pop-up, select Actions.
  3. To request a revision to your invoice, including updating the purchase order number, select Regenerate invoice with updated information.
  4. Read the Request status confirmation, and then click Got it to return to the Documents table. Note that for each invoice you choose to regenerate, you must wait 48 hours to make another revision requests on that same invoice.

To update the purchase order number for another invoice, repeat the steps above.
