Invoices are very important, they help keep track of records and purchases. To locate your invoice from the main front page, click on the dashboard button on the top left corner of the page. From the dashboard then you can navigate to the payment page on the drop-down menu to see all transactions.
Each transaction has 2 options to the right of the panel. Click on the invoice option and a pdf version will pop up. Being a pdf document allows you easily share or print each desired invoice.
