Steps:
Assign the user role
Go to your Settings then Users.
Click on the user you want to assign this role to and activate Archive sales invoices without delivery to the customer.
Turn on the setting Forward to your accountant the sales invoices that were archived without delivery to the customer

Go to your Settings > Outbound.
Scroll down to Archiving and turn on Forward to your accountant the sales invoices that were archived without delivery to the customer.
