Invoicing for cash on delivery orders.

Dear Saleem,

You can create a credit note for the goods that remains undelivered if you have already created invoice.Cancellation of invoices multiple times will raise unnecessary doubts.

In case invoice is not created beforehand you can create the invoice of only those goods which are delivered as under GST law invoices must be raised within 30 days from the date of supply of goods.For details you can contact me at cashivalikhdhari @ gmail.com

Dont no agree with Mr. Shiva. Extract of Section 31(1) for your reference:

SECTION 31. Tax invoice. — (1) A registered person supplying taxable goods shall, before or at the time of, —
(a) removal of goods for supply to the recipient, where the supply involves movement of goods; or
(b) delivery of goods or making available thereof to the recipient, in any other case,
issue a tax invoice showing the descripttion, quantity and value of goods, the tax charged thereon and such other particulars as may be prescribed
