Under " Export on payment of IGST without any requirement of Bond or Letter of Undertaking" - the taxpayer deduct IGST but he/she don't charge is from foreign customer. 

For example: 

If total sale amount is Rs 5,000

The taxpayer will charge Rs 5,000 straight to customer. 

The IGST on Rs 5,000 = Rs 900 is paid separately by taxpayer under "Zero rated supply" and its up to taxpayer to claim the refund later.

My question is, is there a way to show this example in sales invoice in QuickBooks?
