Interest on late payment in case of QRMP Filers

Filing of IFF is optional, and the vendor has not yet uploaded the invoices, so the invoices are not appearing in GSTR 2A/2B of first 2 months of the quarter.

Vendor uploaded all the invoices in Quarterly GSTR 1 and now the invoices are reflecting in GSTR 2A/2B.

So in this situation There's a tax payable if I calculate net tax liability on monthly basis, but no tax payable if I calculate it on quarterly basis..

My question is, whether we need to pay interest on such monthly shortfalls due to vendor's non compliance with IFF??
