Bolt Food Balance is a system that tracks any potential refunds. When you are refunded, the amount will be added to your account as a credit that you can use towards your next order.
You can check your balance in the Payments section. If you don’t see it, your balance is either zero or you haven’t updated the app to the latest version.
You will also see Bolt Food Balance in the basket screen. If the value is positive, your next order will be automatically discounted by the value of your balance, and the balance will be reduced.
