I know this subject has some posts on the archives but I don't think it sorts it out!
When Auspost goes to the Auspost website and calculates shipping it does it accurately - to a point. Auspost is a GST supply and as such the rates returned by the Auspot website include a GST element.
i.e. shipping from Sydney to Sydney for a 200g package is $3.70. Setting Auspot rates to be GST Payable in the postal module causes the order total to show $4.07 and 37c GST. The 37c GST has to be shown because invoices should detail the GST paid. But the 4.07 is now gross/gross.
It needs to show $3.70 on the shipping line and 34c as the GST charged. It could also show $3.36 on the shipping line and 34c GST Charged providing the invoice total is $3.70 for the shipping.
Any help on how to configure this please?
