I think that there needs to be a facility with MYOB AccountRight for entering automatically reversing journals.
This would be a great feature and one that lots of MYOB users would appreciate as...
All you would need to do is have the same function as the current reverse transaction, but the ability to put a different date on it.
IE Accrue the expenses at month end @ 30 June
At 30 June
DR Expenses
CR Accruals
Reverse the above entry, but you want a 1 July date on it.
At 1 July
DR Accruals
CR Expenses
