Out put sales not showed in GSTR-1 but Tax paid to Govt against invoice in GSTRB

The GSTR-3B is a summarised return form while GSTR-1 is a reporting of all output invoices and taxes on them. ... If a system reconciliation were to take place, any additional tax liability would be throw up on it own with the filing of the 3 forms and will have to be paid up accordingly.

Thanks for your reply Sir,

We had got the Notice from GST department because we showed less out put in GSTR-1, and actual output sales showed in GSTR-3B because of that we have paid tax to government and , mismatch showing in GSTR-1 to GSTR-3B, 

We have replied to GST department for mismatch in GSTR-1 to GSTR-3B

As party saying that If He gets the notice from GST Department regarding claiming the ITC , He said he will say We didn't uploaded the GST invoices of party,  But we have paid the GST against invoice in GSTR-B and not uploaded invoices in GSTR-1.

I don't know how to solve the issue.

Kindly suggest on this
