Subcontractor and paying superannuation

Have a cleaning subcontractor who invoices and has their own ABN so they look after their own PAYG.  They send through an invoice so is done as a payable; however, we are required to pay Superannuation to them so have set them up and manually do the Superannuation.  I use their invoice amounts and then do the 11.5% and go into the Super Portal and do the payment quarterly and then code in bank reconcilation the code of Superannuation payable.

MYOB is calculating the invoices and showing PAYG payable and the Superannuation balance is also way off so not sure what it is calculating.

Any suggestions??
