Dear Atools,
Currently, billing does not automatically deduct money from your balance. When you replenish the balance, the money just sits there and waits until you decide how to use it.
In the recent past, our billing automatically debited money from the client's balance, but this led to driving clients into debt without their direct consent, so we cut this feature.
Here you can see your balance -
