adding a Reference Number / PO Number

2014-11-13T09:53:59Z

I have invoices to create that require inclusion of reference number / purchase orders number.
Noticed that under credit invoices, the Customer Reference 'can be used' to accommodate it.

However, for Cash Sales ( where customers paid up before shipping ), there is no Customer Reference textbox.

Please advise the alternatives / possibilities available.
