Can I create a copy of my invoice for my reference?

You can duplicate an invoice by clicking on the three-dot menu next to the invoice in the listing. This will create a copy of the invoice with a different Invoice ID.  

If you would like to keep a copy of the original invoice, you can access it anytime in the Invoices tab. You can also download or print the invoice easily by clicking on the invoice and pressing the corresponding action buttons at the top.
