Cost Feature - Copy of notice of cost emails

What is your challenge?

When sending a notice of cost, the customer does not receive a copy of the email that is being sent to the subcontractor. The customer needs a copy of this email to prove it's been sent and to keep a copy for their records.

How does this impact you?

Unable to prove this has been sent to the subcontractor.
