Can I raise Invoice without submitting new rates to Dept.

Hello,

My company has made revised costing regarding the manufactured goods, but havent submitted the details to the Excise Dept yet. As old stocks are exhausted and new orders being taken, can I raise The Invoice for new rate goods without submitting the details. I will submit the costing details in a few days..

Is there a rule to mandatory submit the Cost Details before selling goods?

This is urgent as my business is getting hampered.

Regards
