Ms. Aey,
I am sorry for this inconvenience
We do really understand your situation also.
But as per new regulation also with BIR (Bureau of Internal Revenue) we also need to follow their rules.
As per additional information, before we only required to register the sales invoice in BIR but as per new regulatory memorandum Order No. 13-2013.
We are required to register all documents including the packing list.
Then normally in new registration will start to Contol no. 0001, but we are still waiting for the approval of our packing list that is why we used the previous one.
Our invoice also is new registered that is why start to 5001, which we need to surrender some invoice which we don't used and they gave us new control no. and new format of sales invoice.
This was implemented by this month September 1, 2013.
We cannot revise the number because this will be the correct control.
But if you will accept, we will include a note below sales invoice and packing list , sample is attached. (please check)
Hope your patience to understand the new regulation also.
We hereby asking your approval and acceptance
Please advise if attached can be more convenient to used for us to revised it.
Thank you!
