Why can enterprises in Shanghai Free Trade Zone open special tickets?

We should understand the difference between ordinary tickets and special tickets. Generally, the difference is the biggest when deducting fees. Because ordinary tickets are not deducted, special tickets are deducted. However, special tickets are often troublesome when invoicing, which requires the buyer to provide a lot of information, while ordinary tickets do not.

In terms of the duration of use, the general ticket is only two months, while the special ticket time is not limited.
