Dear sir
The credit & liability statement of our gstn in the gst portal shows the figure as per our books of account. However an alert message we have received showing difference in gstr1 and gstr3b. Kindly advice what to do.

We also let you inform that some b2b invoices which were shown as b2c was rectified on march'19 gstr1 return by adding in b2b column and reducing that amount in ammendment b2c section
