Draft Purchase Orders contain Items that are yet to be ordered. Draft Purchase Orders are seen in the Draft column in Orders > Purchase Orders.
A Draft Purchase Order (PO) allows you to keep adding products until the PO is ready. You can add all or selected products from one or more Projects and Stock Items.

After the Draft PO is ready, you can export the PO as a PDF document or email or send it to the supplier.
