Dear sir /madam
we sold goods to one of our party ,after receiving goods the party told rate in sale invoice is higher than actual rate and party issued debit note on us after reducing the invoice amount,,
my question is if we not issued credit note against that debit note then what will happen.. will it be problem for us in future...?
kindly clarify to me
