If we received advance for something in the financial year 2021-22 and issued pro forma invoice, paid GST and mentioned that as advance in the GST return of previous year, can we issue a tax invoice (with zero amount due)? Initially that advance was for 50% of the amount but now that amount has been finalized as the total payment so there nothing more to pay. When we issue that invoice, do we have to mention the actual amount in invoice details in GSTR-1 and also in adjustment of advances?
