If we received an advance for the service in February. We paid the GST through challan on time. But it obviously wasn't mentioned in the IFF of February. Then we issued the invoice in March and received the balance payment in March. So do we just have to enter the invoice details in the GSTR-1 or do we also have to mention the adjustment of advance received in February in the GSTR-1 of March?
Thanks in advance for your help.
