To be able to add multiple email addresses in each of the 3 fields.
We send email invoices to the venue we are delivering to and then also to the accounts department so multiple email addresses in 'email 1' would serve that purpose.
It would be useful to be able to send statements to multiple emails as well so 'email 2' could be used to send email statement to the business owner and the accounts department.
If you try to put several email addresses in one field Sage checks the email address and says its not valid.
Multiple email addresses would certainly be a benefit. OK, maybe you cannot have indefinite addresses but in our organisation, at least 50% of our customers require the invocies to be sent to at least 2 people (accounts and the "purchaser")
