But of course!
An invoice is automatically emailed to your listed contact whenever a parcel is shipped via Flaunter.
To resend a parcel invoice at any point in time:
Select 'Sample Tracking' at the top of your dashboard, then select 'Send outs'.
Search for the contact or use the drop down on the right-hand side to sort by 'Sent' or 'Overdue'.
Once you find the parcel, select the three dots on the top right-hand side and select 'View/Edit'.
On the top right-hand side of the send out you can select 'Email invoice'. Double-check the contact's email first before you hit send ;)
