Starting in Version 8.1, you can email previously created invoices to your customers with just a click.
On the Financials>Customer Invoices screen (not Bulk Invoices) on the left is the list of invoices. Next to each is an envelope icon. You need only click this icon to send the invoice to the Client Billing Contact.
