Hi Dorothy, that would be the same cc email address for every customer. What I am trying to achieve is a customised default cc for each customer I have clarified the example.

I know this can be done after creating the invoice, by editing the invoice. But I would prefer it to be the default for each customer as I import my invoices. 

i.e. for my company XYZ ltd. for customer ABC Ltd, [accounts email] is emailed and [customer contact email address] is cc.ed (for every invoice sent to the customer ABC Ltd. by my company XYZ ltd.)
