I would like to know what bill book we required our some products are tax free and some taxable in this case tax invoice required or bill of supply pls suggest us
As per Notification No. 45/2017 – Central Tax dated 13th October 2017
If a registered person is supplying taxable as well as exempted goods/ services to an unregistered person, then he can issue a single “invoice-cum-bill of supply” for all such supplies.
Yes as per Rule 46A , CGST , "Invoice cum bill of Supply" can be issued if taxable & exempted goods supplied to Un-registered person. As its optional so better to maintain just one bill book & issue Tax Invoice
