Buy things do not give the invoice, perhaps he that place is not a formal place to sell things.

That is to say, he did not have the invoice, not with the cooperation of the tax bureau, so that he could not open the invoice with you, can not open the invoice, in this case, you can only not use this invoice.

If it is said to be well from him here to open an invoice, it is still difficult, can only say is to find those who can develop the invoice of the place to buy.
