Excuse me, after the inquiry of invoice by SMS, the old date and invoice amount are blank. What is the reason?

Because the invoices were bought one by one, now I only give you one, and that one has not been opened and has not been handed over to the tax bureau. It is impossible for the tax bureau to know how many invoices a company has issued at the same time when it has finished issuing invoices. Only when the company uses up the whole invoice and then goes to the tax bureau to check the old one for the new one, the tax bureau will display its old check date and invoiced amount, so when you inquire, it will display its purchase date, invoice number, invoice code and company name. Explain that this invoice is true.
