it is important to distinguish fees inclusive or exclusive of GST.
If the price is $5,000 ex GST and you need to calculate total invoice:
$5,000 x 1.1= $5,500 (total including GST)
If the line item is $5,500 (Incl GST) total invoice and you need to seperate the GST component:
$5,500 / 1.1 = $5,000 (ex GST)
