Whether it is compulsory to mention C.I.N. (Company Identification Number) in the Invoice.
whether cin is mandatory to mention in invoice
Whether an invoice must display the Corporate Identity Number (CIN) depends on corporate stationery requirements: excise rules do not mandate CIN on excise invoices, but companies are required to print CIN on business stationery such as billheads and letterheads. If a single document series serves both as a commercial/excise invoice and as company billhead/stationery, the CIN should be included on the invoice to meet corporate compliance. (AI Summary)
