Balance:
The figure shown under “Balance” represents the funds in your Cash Account. You can use these funds to send money, and when you successfully fund your account you’ll be able to see it here.
Available to Spend:
“Available to Spend” shows how much you are able to spend on your Slash Platinum Cards in a given day.
Credit Balance:
Your credit balance shows the amount you’ve already spent from your available credit. Transactions that are settled or pending will count against your maximum credit limit, which means the maximum amount you can spend in a day will be reduced by any pending transactions.
