CREDIT NOTE - GOOD RETURN

Hi all,
we are trading company for packed food & drink.

We are now having problem with the issuance of credit note.

When customer return goods to us, its usually come with a  whole bunch of products,
lets say 12 items of goods & stated in 1 good return note.

According to gst rulling, credit note to issue must contain : number & date of the original invoice.
But for this 12 goods item, there are origin from 12 invoice issued previously.

In this case, can we just issue 1 credit note and notify against any of 1 invoice,
or we must issue 12 credit note (to credit against 12 invoice)?

pls help~~

1 credit note will do. Just state all the 12 invoice numbers and their respective dates on the face of the credit note.

If your accounting software does not allow you to capture multiple imvoice particulars, you may have to do 1 credit note per tax invoice.

Thx Joseph for ur reply =)
if 1 credit note, do we need to specifically stated in the credit note, per item to which invoice there are credited to?
Says item A - credit against invoice no. 00001
Item B - credit against invoice no. 00015
Item C ....
Is it necessary to notify customer In such a detail way?

No need such details, just make reference to the original tax invoices.

Hello,
I issued credit note to a tax invoice but wrong quantity. How do i adjust the wrong credit note.

Issue another Credit Note or Debit Note, and make reference to the original Tax Invoice and the wrongly issued Credit Note.
