The company mistakenly issued 2 tax invoices (with the same sequence number)  for two separate customers. In case one of the customer uses the tax invoice to claim VAT already, does it mean that the other customer does not need to use the tax invoice. How to do for this case?. 

Panwa : For this matter, the company must cancel the other tax invoice that has not yet been used to claim VAT  and issue a new tax invoice (with the same date, but with the correct tax invoice sequence number) to the customer.
