Adding Purchase Order Number

[Guest]

Currently only the Payment Method is printing on the invoice. Is it possible to include the Purchase Order Number on the invoice as well?

I operate a business to business company that relies on customer purchase orders and having the PO number imprinted on the invoice would speed up the payment process.

 

I have the Purchase Order 1.4.1 and osC-PrintOrder with Store Logo v2.0 contrib. along with SPPC.

Any suggestion?
