Can I have a Purchase Order field with QuickBooks Online?
At the time of publishing this article, QuickBooks Online does not have a built-in field for Purchase Order. However, we do have a workaround that works well for many users.
You can add a custom field called "P.O. Number" (must be spelled just like that) and our sync servers will know to store that in our own internal field for Purchase Order. This will then be shown in the Purchase Order column.
