Dear Sir, 

In QB GST exempt GST and 0% GST option are already there, please us the same to do prepare the invoices.

I was doing by selecting GST 0% but when I upload to GST portal it saves it as with payment of GST which is without LUT.

When we select 0% GST it should save it as without GST and with LUT.

It's my priority to help you with exporting your invoices accordingly, @ashish91tulsian.

As per section 16 of the IGST Act, 2017, the export of goods and services is treated as a zero-rated supply. This means that the GST would not apply to the export of any kind of goods or services. Since selecting the GST 0% saves the payment of GST, you need to choose the GST exempt option.

To learn more about the zero-rated supplies and Letter of Undertaking, you can check out these links:
