Hi lola_d,
Thanks for checking that and for the screenshot. I can see what you mean, even though the order number is selected, it isn’t pulling through to the invoice, and at the moment there isn’t a separate field available to show a PO number there as well. Also, just to clarify, the instructions shared earlier by our previous moderator are for the browser version. So right now, only the invoice number will appear on the invoice. I know that’s not ideal if you need to search by order number later on. As a workaround, you could pop the order or PO number into the email subject or message when you send the invoice, so it’s easier to find again later.
