We construct real estate & infrastructure projects for government & private developers. Sometimes our clients (government & private developers) supply material or incur labour charges on our behalf. They debit us for such material & labour charges. Can we take cenvat credit of tax portion on such debits? If yes, are proper debit notes enough for taking cenvat credit or proper invoices are required?
