title: How do I set sales receipt GST (sales tax or GST centre) attributes via external application? (Non US)
body: <p>I am working with a Non US version of QuickBooks online (QuickBooks Online Plus Australia). I'm trying to deal here with our Goverment services tax or GST which is 10%. What I want to do is create a sales receipt that calculates the total charge to the customer and <strong><em>displays</em></strong> the GST component through calculation. Right now the GST is being added to the charge, I simply want to acknowledge how much GST is included in the total charge.</p>
  
  <p>I am using the traditional SDK QBXML for QB online (SalesTaxLineAdd). I have alternatively tried setting up the tax through the GST centre but doing so seems not to be harmonious with the SDK because when I create a sales receipt through the SDK in line with the GST centre, for the field "All Amounts Are" it automatically sets it as "Out of Scope of GST" and ideally I would want this to automatically be "Inclusive of GST". For the line Items the SDK doesn't set the "GST Which" field at all which then requires manually setting it to GST. What would be ideal is if the SDK did this all automatically.</p>
  
  <p>As a workaround using the SDK and the SalesTaxLineAdd element, I have been subtracting 10% from each line item price so that "SalesTaxLineAdd" adds the 10% which then represents the true total. I will accept this If I have to but if a customer calls and asks how much they paid for their last order I will be telling them the price exclusive of gst.</p>
  
  <p>If I work with the REST API v2 is it more flexible for this specific scenario?</p>
  
  <p>Your help is appreciated</p>
