Is it difficult to upgrade the company invoice?

Company invoices are difficult to upgrade. Judging from the relevant public information, it is not easy to ensure that the tax burden of invoices is at least 1 to 2 cents per month, and it is not easy to buy tickets for at least 5 months in a row. Invoice promotion needs to be applied according to the real situation of enterprises. If it is really a business need, you can apply directly at the electronic tax bureau.
