Is there a way to create a Purchase order from an invoice?
With Square for Retail Plus, you can create purchase orders from your online Square Dashboard by logging in then heading to Purchase Orders > click Create Purchase Order. You can also easily generate purchase orders for items likely to run out of stock - you can learn more about auto generating Purchase Orders here.
Creating a Purchase Order from an Invoice would be considered a feature request at this time, @Allison-PNR.
