How to submit GSTR1 or 3B, If the invoice is generated in a month and payment received in the next month or 2 months later? Let me ask through an example, There are two company A & B. Company A provide services to B. Company A Generated an Invoice against the services taken by B in the month of September and Company B paid the fee in the month of November. In this case on which month I can file or submit this transaction in GSTR 1. November (Invoice generated date) or September(Payment receiving date)??
