So when I checked my adwords account it read that i owe a total of 48 dollars in advertisement clicks. 18 dollars were from last month. However I checked my bank statement and there are no charges for this. My adwords accoutn says the 18 dollars is an outstanding balance. It also has my charges for this month but next to it says "carried over to August" I dont undertstand why they have not billed me yet? Is there a minimum that has to be reached or is there something wrong with my account info? Any advice would be very helpful.
