Joining you here to offer my help and answer your question about emailing invoices, simon.

A new feature was recently added that would let you CC or BCC the other email address when sending out transactions from QBSE. I'd be glad to share the details on how you can do it:

1. Create an invoice or open the existing one.
2. Choose the Send button.
3. Click the Cc/Bcc link and enter the email address in their respective fields.
4. Select Send.
