Something needs to be done about the CCS estimates. Every week when the system calculates our family payments, when the actual CCS updates on a Monday the payments are out and I need to manually adjust every one of the scheduled payments as it's not done automatically because the payment increases. I know sometimes there is a difference of a few cents to a couple of dollars due to rounding but we consistently have families balance differ by over $10 and sometimes as much as $30-$40. This cannot be due to rounding and cannot be a family Centrelink issue as it happens with almost all of our families. Last week I worked out the CCS estimate myself and the system clearly had it wrong so calculate the weekly payment as the wrong amount.
