Hi jsilov ,
Apologies for any inconvenience caused.
That is very weird. I tried to reproduce your issue on my dev server. The correct purchase price was copied to the PO.
Please note that prices are copied without taxes. Is the "Prices entered with tax" option set to "Yes" in WooCommerce Settings -> Tax? If so, ATUM will remove the taxes from the purchase price value when creating the PO.
Best Regards,
José Andrés
