## Purchasing Power Purchasing Power = Current Balance + Credit Limit - Temporary Hold ### Current Balance The actual amount in your account balance ### Credit Limit A set amount that you can access as needed. Your current credit limit is 0.00. If you spend more than the credit limit, you will be automatically deducted the total charges from your default payment method. {% hint style="info" %} **Note** To avoid possible loss due to service downtime, please make sure that your purchasing power is not negative. {% endhint %} ### Temporary Hold * In pay-as-you-go billing method, a one-billing-increment amount will be temporarily "frozen" in your order to verify that your account is valid and has enough balance. This is required to guarantee your transaction. This one-billing-increment amount is called Temporary Hold. * If your account balance is insufficient to pay for the Temporary Hold, you will not be able to complete your resource activation. * When your resources are released without any overdue payments, your Temporary Hold will be unfrozen and returned to the account balance. If there is any remaining account payables, your Temporary Hold will be used to offset. ## Refill Balance * When your resources are released without any overdue payments, your Temporary Hold will be unfrozen and returned to the account balance. If there is any remaining account payables, your Temporary Hold will be used to offset. Click **Refill** beside your purchasing power to refill your balance.
