On the MYOB Business dashboard, the amount shown under Superannuation Payable is in fact the sum of Superannuation Payable plus PAYG Withholding Payable. I have confirmed this by checking against ledger reports.
To correct this, the heading should be changed from "Superannuation Payable" to "Superannuation and PAYG Withholding Payable", OR even better display Superannuation and PAYG Withholding as separate items.
As it currently stands the Dashboard is showing wrong information.
