All too often a cheque bounces and you need to note this so that the child's account balance will show that the amount is unpaid.
Click on "Finance" and then on "Bounced Cheques".
You can search by all your cheques or a range of cheques.
1) Tick the box next to the cheque you want to bounce.
2) Click "Discard".
The payment is now deleted and the amount becomes due again.
