There is an 'Issue Invoice' link from each
order. This can be used to view a print version of the invoice for
printing if you require a customer be sent a print copy with their
order, or by post to request payment. Note that viewing or printing
this invoice does not automatically check the 'An invoice for
payment has been issued' box. That box must be checked manually by the admin user
to confirm that the invoice was sent to the
customer.
Customers may view invoices from within
their 'My Account' section in a print-ready format so some stores may
decide to use this as the primary delivery method for invoices and
receipts.
