What is the difference between the general fapiao and the special VAT fapiao?

General fapiao are issued after a purchase, and they are split into the categories of personal and company fapiao.  These categories allow the government to know who can claim the amount indicated in the purchase.  General fapiao are far simpler than special VAT fapiao, which contain much more detail about the vendor involved in the transaction.  Unlike the general fapiao, special VAT fapiao can be used for tax deduction services.
