Why vendor email is missing in PO creation form?

Vendor email is missing in the Purchase Order creation form due to a bug in QuickBooks API that does not allows to save vendor email. ApprovalMax completely depends on QuickBooks Online here and we can't fix this on our side unfortunately. This bug is planned to be fixed in the new version of QuickBooks API (v4).

For the time being you should go to the Purchase Order in QuickBooks after Purchase Order has been created there by ApprovalMax, set the email and send Purchase Order to the Vendor.
