To view your billing information go to REI Landleads > Account on your WordPress Dashboard.
Scroll down to the Billing section. This will be blank as the subscription you purchased is a lifetime subscription and we wont need to bill you again.
However, if you do wish to add the details, you can fill the boxes out and click the Update button to save.
Scrolling down to the Payments section will show you details of your purchase including the purchase ID, date, and the amount. If you need your invoice, click on the invoice button.
