C-Form

Sir/Madam,

for eg. This is an Interstate transaction.

Our approved & Purchase Order Rate is Rs.100 per unit., but the vendor not agreed for that price. They are asking Price Increase for Rs. 110 per unit. In the meantime we need materials urgently.

Our vendor made invoice for Rs.110 per unit. We bought it and used it for Production. After due date we made payment for Rs.100 only . Because our approved rate is Rs.100/- .For  Remaining Rs.10 we made debit note as Price difference.

Now the party asking 'C" Form for that Bill. What we can do? whether , we issue the Form for the Invoice value (OR) the payment amount what we made.
