Everybody has this.
That's how much your bill has to be before they bother to actually bill you. If you only owe $5, that balance will carry forward until you owe more than $9.23, and then they'll bill you on the 29th.
Mine also says $9.23 and I don't owe anything this month, so they won't be billing me until I actually owe them money for something, like a domain registration.
Farther down under my Hosting Plan is the money I paid and when my plan expires.
