the reason why the invoice can't be folded is not the invoice, but the deduction. The invoice issuing unit usually issues two bills together, one is the invoice copy and the other is the deduction copy. Invoices are used for settlement and can actually be discounted. What can't be folded is the deduction coupon. There are many unique identification matches in the upper right corner of the deduction coupon, which are used for tax authorities to check the deduction. After folding, the tax authorities may not be able to check it by computer, but will not recognize it, resulting in a financial loss of 17%.
