If your firm is registered under GST Act, you are eligible to issue GST invoice.

Purchase bill is required to avail ITC. So if you do not have any purchase bill you cannot avail ITC credit on your purchases.

So you are completely within the law in issuing GST Tax Invoice but you cannot avail income tax credit on those purchases.

Hello,

Yes you may raise the invoice and there will be no problem in filing return, however you will not then be eligible for input tax credit.

You cannot raise an invoice without GST.

If the contract manufacturer do not accept without GST then it will become a problem for you, hence you better charge GST and add it in your returns.
