Rewards Vault has the option for you to create an invoice at anytime. It can be settled at the time you create it or created to pay at a later date.
Navigate to your Manage Funding Page.
Select the ‘Create Invoice’ Button.
Enter the amount you want to pay and hit ‘Submit’. If you would like to settle the invoice at a later date toggle ‘Settle Now’ to off before clicking submit.
Success! Once the invoice is created you can scroll down to the transaction table to download the invoice.
